Two Notes Torpedo VB-101

The Torpedo VB-101 is a DI for your head amplifier composed of 3 main parts: a 150W RMS Loadbox to play silently with your amp or preamp, a speaker & miking simulator powered by the acclaimed Torpedo technology with all your favorite cabs inside and a Post-FX section with all the processing effects you usually need when miking a guitar cab (low-cut filter, 5-band EQ, exciter, compressor).

Using the Torpedo VB-101

The Torpedo VB-101 is made to be used with a guitar/bass amp or preamp.
Plug it in place of your regular cabinet and enjoy all the great characteristics of your audio amplification chain (from the guitar to the amp, including effects pedals) silently!

The Torpedo VB-101 can replace the whole guitar sound-recording process with some powerful simulation of the cabinet, microphone, mic preamp and studio acoustics. Choose your speaker among the more than 50 available, your microphone among the 8 most used studio mics and sculpt your sound with the included effects section (EQ, Exciter, Compressor).

Sound recording is done in silence and with perfect control of every critical parameter.

In the studio

VB-101 in studio (2)

In a home / project studio, where the cabins are not necessarily suitable for miking guitars (and the resulting high volume), the Torpedo allows engineers to achieve sound recording silently with no compromise with regards to sound quality.

For studios already equipped for miking guitar (cabins, microphones), it offers an alternative to the regular sound recording process and can also be used as an addition to provide a wider range of possibilities at the mixing stage.

Another common use in a studio environment is when you need to record a whole band in live conditions. The Torpedo VB-101 then allows you to completely isolate the sound from the bass guitar and other instruments without necessarily having a dedicated cabin.

On stage

On stage, the Torpedo VB-101 will be a big asset for the comfort of the musicians and the public.

Find your own sound every night, gig after gig, do not be dependent on the bad microphone or the one not necessarily very well placed, etc.

The sound recording is not “polluted” by other instruments, making the FOH and personal monitor mixes much easier to do and more comfortable for the musicians.

Dual Miking

The new feature of the Torpedo VB-101 is what every sound engineer wants: the possibility to precisely place two microphones in front of a cabinet, or to select two different cabs and mics to mix the sound as you wish.


In the studio, it can be very interesting to record a raw track that you can later reprocess (we call this “remiking”) at the mixing stage thanks to the Torpedo VB-101. This allows you to concentrate on the music when recording, not on the sound

Of course, you can record both processed and unprocessed signals to your DAW at the same time.

Torpedo Remote

The use of computer stations has become a must these days, that’s why we have developed an application to control the Torpedo VB-101 remotely from your Mac/PC via the USB connector on the rear panel of the Torpedo VB-101.

With its clear and intuitive interface, the Torpedo Remote software will give you access to all the VB-101 parameters, loading and saving presets, loading new IR’s and updating your VB-101. Via an enhanced graphical interface, you have access to easier management of the VB-101′s speakers and presets.

The Torpedo Remote is Mac/PC compatibe and can be freely downloaded in the downloads section.

Two Notes Torpedo VB-101

High-quality electronic design

The best simulation is nothing without a perfectly designed analog and digital circuit. Two Notes focuses on the whole signal chain, from your amp or preamp output to the PA, monitor, headphones or recorder to ensure the best performance. Guitar and bass players deserve studio quality gear !

Power amp emulation

Plug your preamp directly into your Torpedo VB-101. It embeds our component-based tube power amp simulation. Simply choose the amp design and characteristics, and select the tube type.

Torpedo Technology

Highly realistic speaker simulation is achieved by use of convolution. Two Notes started from that technology and brought it much further, to accurately reproduce the characteristics of the whole miking chain (speaker, microphone, preamplifier, studio room acoustic).

Many parameters influence the sound of your guitar or bass rig when it comes to recording. Taking good care of the cabinet selection and miking will dramatically improve the sound of your takes. The Torpedo simulation reproduces the tiniest variations of a cabinet behavior such as frequency response and distortion (*). Move the microphone in the virtual studio room thanks to the Torpedo IR synthesis, control the phase with the Variphi: all the settings you need to achieve great recordings are here.

The VB-101 gives you a miking simulation using your own real amp.

It offers you all the advantages of a silent, portable and quickly configurable system.

The VB-101 gives you always the same sound you want wherever you play with a real high-end amplifier, and with a professional miking quality.

The sound of a bass or guitar amp is generally made with a preamp and a power amp, especially in the case of a tube amp. A head amp already contains a preamp and a power amp. The most common way of recording an amp is to plug the output of the power amp or the output of the head amp into the “Amp” input of the VB-101.

Besides, the VB-101 includes a XLR line input, symetrical or asymetrical, in which you can connect a bass or guitar preamp. This way, you can take advantage of the VB-101 simulation without having to add a power amp to your preamp.

A full tube amp cannot be used without an output load such as a speaker.
The VB-101 includes an 8 ohms load, which replaces the speaker and dissipates power, allowing the use of the amp without any danger.

However, the fact that the VB-101 is a very silent unit should not make you forget that your amp is still working its normal way. Turning up the volume of your amp brings huge output power ! Most amplifiers aren’t designed to work at a very high level of power. In order to avoid any risk, we recommend not to use your amp near its maximum volume. Ask your amp manufacturer for more informations.

The VB-101/VM-202 is a state-of-the-art product giving you a professionnal quality miking simulation. It uses both analog and digital technologies to offer the best interface possible.

Sound processing is digital and uses high-end DSPs specialized in audio processing. AD and DA converters are top notch, offering a totally transparent 24bits/192kHz sampling.

Inputs and outputs are either digital (AES/EBU and S/PDIF) or analog. The loadbox, the input gain stage and the input and output line buffers are analog circuits.

The VB-101/VM-202 is fully controllable with MIDI and easily finds its place in a MIDI environment.

It reacts in real time to Program Change messages so that every sound processing parameter can be controlled by any MIDI remote device.

For example, you can switch between presets on stage with a MIDI floorboard, control the output volume with an expression pedal or, in studio, move the position of a microphone to experiment new sounds.

The digital inputs and outputs of the VB-101/VM-202 use professionnal AES/EBU and consumer S/PDIF formats. The VB-101/VM-202 can be set as master or slave for transmitting.

In master mode, the VB-101/VM-202 generates its own clock at a selectionnable frequency. In slave mode, you can sync the VB-101/VM-202 with the AES/EBU or the S/PDIF signal, or with the Wordclock input.

The digital inputs and outputs work with frequencies from 44.1 kHz to 96 kHz.

Therefore, the VB-101/VM-202 can be used alone or find its place in a more complex digital audio system.

Installing the VB-101/VM-202 in slave mode

We recommand to install the VB-101/VM-202 in slave mode : this way you will be able to sync the VB-101/VM-202 with your sequencer/recorder by selecting the working frequency in your project.

Please note that the internal working frequency in the VB-101/VM-202 is always 96 KHz. Changing the sync frequency has no impact on the Torpedo process quality.

  1. Check that your digital interface is configured in master mode.
  2. In the setup menu of the VB-101/VM-202, select sync, SPDIF, AES/EBU or Wordclock to indicate the machine on wich signal it has to be synced.
  3. Connect a SPDIF or AES/EBU cable from the digital interface OUT to the VB-101/VM-202 IN, or a wordclock cable from your master clock. On the Torpedo idle menu, you must see the indication “Lock”.
  4. Connect a SPDIF/AES/EBU cable from the VB-101/VM-202 OUT to the digital interface.
  5. In your sequencer recorder software, select the digital input for recording (please refer to the user manual of your digital interface/software). You should ear the signal coming from the VB-101/VM-202.

The Torpedo Capture Software is a simple but powerful tool to make professional impulse responses compliant with the Torpedo VB-101.

Here is the gear you need to do the capture :

  • A MAC or PC computer with an ASIO/Coreaudio soundcard embedding at least one line output and one line input. In an ideal case, the soundcard can go 24bits/96KHz with the best signal/noise ration and THD.
  • A power amplifier that can work at 250W/8ohms with the lowest possible distortion, linear frequency response and the lowest possible output impedance. A solid state studio monitoring amplifier fits perfectly for this task. A Tube guitar amplifier could be a fun thing to try, but as they are everything but linear the result may be… fun.
  • A cab you want to capture
  • A microphone you want to capture
  • A microphone preamplifier you want to capture
  • A room were you can play loud !

There is the principle :

the Torpedo Capture Software will send a test signal through the whole cab miking setup and record the result. After a few calculus, it will create a .tur file that you will upload on your VB-101. The whole process can be done in less than 5mn.

Phase 1, the Torpedo Capture Software :

Download and install the Torpedo Capture Software

Launch Capture, choose the driver you want to use (File menu/Audio drivers/ OK to save and quit this window), the recommended frequency is 96KHz, the latency must high enough in order to avoid and overloading of your CPU. We recomand ASIO or CoreAudio drivers.

For example, we will use the line output 1 and the line input 1 of the soundcard.

Phase 2, setting up the recording :

Plug a cable from the output 1 of the soundcard to the input of the monitor amp.

Plug a cable from the output of your amp to your cab. Please take care of the amp output impedance, regarding the cab impedance.

Place your microphone the way you want in the record room. Don’t forget that the mic placement can’t be changed in the VB-101 with user impulse, so take your time to do several measurements to find the right spot.

Plug a cable from the microphone to a mic preamplifier. Please note that the response of the preamp will be captured, changing the preamp may change the overall sound.

Now plug a cable from the preamp output to the line input 1 of the soundcard.

Phase 3, levels :

It is important to note that the level of the test signal going through the cab matters. Based on our experience, we recommend to play at a “rehearsal level”, in other words at the level you are used to record/play. The purpose is to be as close as possible to the real conditions.


Playing at very loud levels may cause permanent damages to your hearing. The test signal is very energetic, so please use the “test” function of the Torpedo Capture Software, starting from low levels, before cranking the amp.

The bargraph in Capture should be between -14dB and -12dB to match perfect gain adjustment.

Phase 4, creating the file and sending it to your VB-101 :

On the Torpedo Capture window, click on the “MEASURE” button. Choose a destination for the file, the best is to select the DATA directory of the Torpedo Remote.

The test signal is called a sinus sweep. The signal will sweep from the ultra low frequencies to the highest and even after the cabinet will cut. Please don’t make any noise before the test is finished. Please control that there is no glitch/clic/pop in the sound that could be a consequence of a latency parameter set to low. If you hear this kind of noise, please increase the latency.

The measure process takes 1 minute, a pop up message will warn you when it’s done.

Your computer will… compute the file to create a .tur file in the previously selected location. This process could take a few minutes, depending on your CPU power.

Phase 5, uploading the file into the VB-101 :

Launch the Torpedo Remote Software

Go to the menu File/Memory Management, click on the .tur tab.

On the left you should see the new created impulse, on the right the locations on the VB-101 to upload it. Right click (or CMD+click on a MAC) on the .tur file, select “move to” and the location you want the file to be uploaded. it is possible to take several .tur in the same time, select the location of the first one and the others will follow.

Once it is finished, quit the Memory Management window and enjoy your new personal cab.

Yes! This is what Dual Miking is about.

Provided you have updated the device’s firmware, the VB-101 will simulate two speaker cabinets and two microphones at a time. Choose them from the library of available cabs and mics, and position them at will.

You can choose to place two different mics in front of the same speaker, or two mics in front of two different speakers.

If you need to update the firmware, connect the VB-101 to the free Torpedo Remote software while also connected to the Internet, and let the firmware update automatically. Then restart the device to complete the updating process.

Yes, you can plus as much units as there are USB ports available on your computer !

Each unit can be named in a dedicated menu. The Torpedo Remote software lists all units and let you control the ones you want.

Latency is the time taken by the processing between an incoming “dry” signal and the outgoing “wet” signal.

The digital transfert AES/EBU or S/PDIF => VB-101 => AES/EBU or S/PDIF takes 512 samples with an internal processing at 96 kHz, i.e. 5.33 milliseconds.

The analog transfert (analog => VB-101 => analog) takes 5 milliseconds

These are measured values, please be awared that the value you can read on your asio/core Audio driver display of you DAW is most of the time wrong and can’t be compared to a measured value. The ony way to measure your DAW’s latency is to use a latency compensation plugin and to link one input to one output.

We made a lot of tests with professional guitar players and bass players to find the good latency value. During these tests, the only way to clearly notice a 5/6ms latency was to add a non delayed signal to the delayed signal

The latency of the Torpedo system direct to digital is comparable to similar latencies when recording to a DAW or using the current industry standard digital touring consoles, using traditional mic and cabinet technologies

No, the VB-101 does not have an impedance selector. The loadbox impedance is 8 ohms fixed which is what most bass and guitar amps provide.

No, the VB-101 only includes a loadbox, in order to play the amp without any sound. The “Speaker Thru” output allows you to connect the VB-101 to a cabinet and get the normal sound of your amp (true bypass) without any volume reduction.

This allows you to record your amp with the VB-101 and, at the same time, by the classic way with cabinets and microphones.

In order to connect your amp to the VB-101, you’ll need a speaker output from your amp. Even though most amplifiers do provide one, please take the time to check your amp. If such an output isn’t available (which may be the case with some combo amps), note that it’s often possible to add a speaker output and you may ask then a qualified technician.

Connecting the VB-101 to your amp is easy :

  1. Plug the loudspeaker cable to the 8 Ohms output of your amplifier
  2. Plug the cable to the “SPEAKER INPUT” of the VB-101

Please note that it is very important to use a 8 0hms output on your amp, not a 4 or 16 Ohms one. Check your amp’s user manual if needed. Not respecting this rule could leads to serious damages to your amp or the VB-101.

Always use a speaker cable (two conductors unshielded, usually thicker than an instrument cable) to connect your amp to the VB-101.

The VB-101 is Mono In to Dual Mono Out. This means that the input is mono but the two outputs (left-right) are both delivering the same signal.

It is also possible to output the dry signal on one output and the wet signal on the other.

When the Spatial effect is activated, the output becomes stereo.

Please refer to the excellent WIKI article here :

The power dissipation of the VB-101 has been carefully designed so that the machine will never go on overheating. The temperature of the machine is constantly monitored and adjusted by an active system of sensors and fans.

Overheating should not be expected in common situations of use.

In case of problem, a first visual warning will appear on the screen. It will be followed by an audio warning and sound will be cut. This state warns of the existence of an unusual and risky situation. If the problem persists, the VB-101 willl activate a protection state where it stops running and heating, without damaging the amp plugged in. Hence, the use of the VB-101 is totally safe.

The VB-101 can handle a maximum of 150 watts (RMS). This means that if your amp’s power rating is lower or equal to 150W, you can safely use it with the VB-101.

You can use the VB-101 even if your amp only has a 4 (or 16) ohms output.
But, in this case, you must connect a speaker cabinet with the appropriate impedance into the “Thru” jack output.

The USB connection of the VB-101/VM-202 only allows for remote control from a PC or a Mac computer. It does not transfer any sound. You need to be in possession of a soundcard with line-level analog inputs/outputs, or digital AES/EBU or S/PDIF.

To digitally record the VB-101/VM-202′s sound, two digital outputs are provided (AES/EBU and S/PDIF).

The VB-101 is not an amp simulator.

It requires a guitar or a bass amp and allows you to record this amp directly, by simulating a cabinet and a microphone in a studio environment.
It simplifies the miking of an amp.

The VB-101 is a speaker and microphone simulator. It makes the process of recording an amplifier easier.

The classic way of recording an amplifier usually implies to plug the amplifier into a cabinet and to record the sound of that cabinet with a microphone.

The VB-101 replaces both this cabinet and this microphone with the same studio quality.
It allows to have a “studio” sound everywhere : at home without making any noise, on stage preventing damages to the microphones, in studio to gain time…

The Torpedo VM-202 simulates 2 different miking setups (PA/Cab/Mic) simultaneously.

The Torpedo VB-101 now also does so (version 2 of the firmware): this is its new Dual Miking feature (see pic opposite).

The PI-101 WOS allows you to add up to 100 simulations in one instance.

PI-101 WOS multiple=

The Torpedo Live and C.A.B. can simulate one miking setup (PA/Cab/Mic) at a time.

Principle :

For recording, a particular configuration allows to take full advantage of the great flexibility of the VB-101. This particular way of connecting the machine allows you to rework a recording after it’s been recorded.

The reamping techniques are already known (recording a guitar or bass through a DI and sending this signal into an amplifier), we’re going to talk here about something we call “re-miking”.


This is done in 2 steps :

  1. Dry recording of the amplifier (simulation bypassed, or using the “PRE-SIM OUT” output (number 11 in figure).
  2. Using the Torpedo VB-101 like an external processing unit into a digital loop through the AES/EBU or the S/PDIF I/O.

In this configuration, the analog-to-digital conversion is done by the studio converter. Note that it is possible to get a dry signal with no simulation from any outputs of the Torpedo VB-101 if you want the VB-101 to do this conversion.

An even more interesting possibility consists in getting from the Torpedo VB-101 a dry output signal with no simulation and a processed signal at the same time. You can then get at the same time, in one take, a classic track recorded with a real cabinet and a microphone + a simulated track using the Torpedo VB-101 library of speakers and microphones + a dry digital track with no simulation, for later re-miking. This gives you a large amount of sonic possibilities, making you sure to get the tone you’re looking for !

Tutorial :

We recommend doing the recording and the re-miking using the digital I/Os of the VB-101. In this tutorial we will be unsung the digital capacities of the VB-101 assuming the user owns a sound card embedding digital I/Os in coaxial SPDIF or standard XLR AES formats.

1- Setup connections

  • Plug your speaker out of the amp to the VB-101 speaker in.
  • Plug the SPDIF/AES out of your sound card in the Torpedo SPDIF/AES in
  • Plug the SPDIF/AES out of your VB-101 in the sound card SPDIF/AES in (now the digital loop is done)

2- Setup your VB-101 and the recording software for recording

Torpedo VB-101 :

  • Under the “setup” menu of the VB-101, go to Audio/Input Select, choose Amp.


  • Under the setup menu, go to Audio/Output Mode and select Wet/dry. The wet signal from the amp will be sent on the left channel (both digital and analogue) of the VB-101 and a dry signal on the right. This way you can play with a wet signal while recording the dry (and the wet, if needed).
  • Under the setup menu, go to Sync/Sync and select the digital clock the VB-101 will be synced on (at least SPDIF or AES/EBU, WordClock if you have a master clock in your setup). We recommend putting he VB-101 in slave mode so you can control the digital out frequency of the VB-101 in your recording software.

Sound card :

  • Select the Clock/Master mode on your sound card so your DAW is the master clock of the setup.
  • Make sure the VB-101 is synced to your DAW and that you receive the signal from the VB-101 when playing.

Recording Software :

  • Create a track (mono or stereo). Select SPDIF1/AES1 as an input (you will record the left channel, i.e. the wet signal).
  • Create a track (mono or stereo). Select SPDIF2/AES2 as an input (you will record the right channel, i.e. the dry signal).

For any problem concerning your sound card configuration, please refer to your sound card user manual.

Set the software on record mode, you are ready to go.

3- Re-miking

After you recorded all your dry tracks, you may turn off your amp and configure your sound card and VB-101 for re-miking.

Torpedo VB-101 :

  • Under the “setup” menu of the VB-101, go to Audio/Input Select, choose SPDIF or AES/EBU.
  • Note that by selecting a digital or analog line input, the Load Compensation parameter will be automatically deactivated.

Recording software :

  • Select one track with dry signal, and send its output NOT to the master bus (default setting) but to the SPDIF/AES out. For example, in Reaper, uncheck the “master/parent send” under the I/O window of your track. Select SPDIF1/AES1 under the Audio Hardware Outputs/Add Audio Hardware Output list.
  • Create a track (mono or stereo). Select SPDIF1/AES1 as an input (you will record the left channel, i.e. the wet signal).

For any problem concerning your software I/Os configuration, please refer to your recording software user manual.

Set the software on record mode, you are ready to re-mike !

The TORPEDO VB-101 embeds a temperature-monitoring system and an active security load to prevent any and all damage that might be caused to either user or product by overheating or by some improper use of the TORPEDO VB-101 with a guitar or bass amplifier.

When the TORPEDO VB-101 is OFF, the loadbox is not running, the Speaker Input is wired to a 168-Ohm security load.

When the TORPEDO VB-101 is ON, an active switch relay activates the loadbox so the amplifier “sees” the resistive loadbox. The DC impedance of the resistive loadbox is set around 8 Ohms.

When you are playing with your amplifier, the power sent to the TORPEDO VB-101 is turned into heat. The purpose of the high-quality Maglev fan placed at the back of the TORPEDO VB-101 is to extract that heat and cool the unit down.

At first, the fan will run slowly (or not at all), and it will start rotating as soon as the temperature is high enough. That way, you can operate in silence by choosing a proper amount of power (the output volume) on your amplifier.

Two things may happen while you are playing:

1- If the power is cut down on the TORPEDO VB-101, it will instantaneously switch to the security load, which is safe for your amplifier(*).

2- If the TORPEDO VB-101 is overheating, the unit will switch to the security load. A message appears on the screen “Overheating alert — Stop playing, let the unit cool down.” The sound is switched off so you will notice the problem even if you are not in front of the machine.

Once on the security load, your amplifier will see higher impedance and will stop sending too much power. An amplifier can stand a higher impedance rating but we recommend bypassing the power amplifier as soon as possible. Let the TORPEDO VB-101 cool down to a proper temperature, and the warning notice will disappear as soon as the temperature is back to normal.

(*) You should not be playing when on the security load. Your amp is safe when simply powered up on the security load, but it is nonetheless unsafe to play on the security load over a long period of time.

Zum Schutz vor Verletzungen oder Gerätebeschädigungen, die durch Überhitzung oder unsachgemäßen Gebrauch in Verbindung mit Gitarren- oder Basseverstärkern entstehen können, wurde im TORPEDO VB-101 ein Temperatur-Überwachungs-System sowie ein aktiver Sicherheitswiderstand integriert.

TORPEDO VB-101 im ausgeschalteten Zustand: die Loadbox ist nicht aktiv, auf den Speaker Eingang wird ein 168 Ohm Sicherheitswiderstand gelegt.

TORPEDO VB-101 im eingeschalteten Zustand:  mit dem Einschalten des TORPEDO VB-101 aktiviert ein aktives  Schaltrelais die Loadbox – der angeschlossene Gitarren- oder Bassverstärker erkennt die reaktive Loadbox, die Impendanz der reaktiven Loadbox wird auf ca. 8 Ohm geschaltet.

Während der Benutzung mit einem angeschlossenen Verstärker wird die am TORPEDO VB-101 ankommende Verstärkerleistung in Hitze umgewandelt. An der Rückseite des TORPEDO VB-101 ist daher ein hochwertiger MAGLev Lüfter verbaut, der die Hitze abführt und das Gerät entsprechend kühlt.

Der Lüfter wird erst mit dem Erreichen einer bestimmten Höchsttemperatur aktiviert.

Durch die richtige Einstellung der Ausgangsleistung (Output Volume) am angeschlossenen Verstärker, kann der Lüfter des TORPEDO VB-101 somit für einen lautlosen Betrieb inaktiv gehalten werden.

Folgende 2 Szenarien können beim Betrieb des TORPEDO VB-101 auftreten.

  1. Bei einer Unterbrechung der Stromzufuhr am TORPEDO VB-101 wird umgehend der 168 Ohm Sicherheitswiderstand am Speaker Eingang aktiviert – der angeschlossene Verstärker bleibt dabei unbeschädigt.
  2. Bei einer Überhitzung des TORPEDO VB-101 wird ebenfalls der 168 Ohm Sicherheitswiderstand aktiviert. Auf dem Display erscheint eine Warnmeldung :  “Overheating alert — Stop playing, let the unit cool down.”

Zusätzlich wird das Ausgangssignal TORPEDO VB-101 stummgeschaltet.

Durch die Aktivierung des 168 Ohm Sicherheitswiderstands wird der angeschlossene Verstärker daran gehindert eine zu hohe Leistung auszugeben. Auch wenn dadurch am Verstärker keine Schäden entstehen, sollte das Verstärkersignal schnellstmöglich gesenkt oder unterbrochen werden.

Lassen Sie den TORPEDO VB-101 ausreichend abkühlen – sobald eine akzeptable Temperatur erreicht ist, schaltet sich der Sicherheitsmechanismus ab und das Gerät kann wieder normal verwendet werden.

We recommend placing the distortion and wah BEFORE the amplifier, and the Delay, Chorus, Reverb, or any modulation effect AFTER the VB-101.
This is what is usually done in studio, and that way all the stereo effects will be preserved and sent to the PA.
