Recommendation on the proper use of a
loadbox with a tube amplifier
1 What is a loadbox?
In the normal use of a tube amplifier, it is highly recommended that you always connect its power
output to a speaker cabinet prior to powering it up. The speaker cabinet (4, 8 or 16 Ohms) must
always be connected to the corresponding speaker output of your amplifier. Not doing so can lead to

torpedo_live:torpedo_live_user_s_manual http://wiki.two-notes.com/doku.php?id=torpedo_live:torpedo_live_user_s_manual
http://wiki.two-notes.com/ Printed on 2018/07/25 19:55
partial or complete destruction of the output stage of the tube amplifier.
Most tube amplifiers makers protect their products with fuses or other protection systems, however
some amplifiers are still insufficiently protected. It is impossible to predict the behavior of all the
amplifiers on the market in case of use without a load (a speaker cabinet or a loadbox).
The electronic term that describes the speaker cabinet with respect to the amplifier is the “load”: we
say the cabinet “loads” the amplifier. The term “loadbox” is used to describe any product that
provides a load to the amplifier. The main parameter of the loadbox is its impedance, expressed in
Ohms. An 8-Ohm loadbox must be plugged to the 8-Ohm speaker output of the amplifier.
The power sent to the load is turned into heat, so please follow the cooling recommendation in the
manual — otherwise overheating may cause damage, both to the loadbox and to the amplifier.
The Torpedo Live is a digital loadbox. This term indicates that the Torpedo Live is a load which can
electrically replace the speaker cabinet while dissipating (transforming into heat) the power coming
out of the amplifier.
Within the Torpedo Live is a Reactive load. A Reactive load simulates the complex impedance of a
real speaker.
Always connect the speaker out of your tube amplifier to an appropriate
load (speaker cabinet or loadbox). The Torpedo Live, once powered up,
is such a load. Please note that you should always power up the
Torpedo Live before your amplifier. The maximum admissible power of
the Torpedo Live is 100W RMS, your amplifier shouldn't be set to play at
a higher output power value. See this article if your amplifier is more
powerful than 100W.
2 Which output volume for my amplifier?
The correct use of your amplifier with a loadbox requires some precautions. Because of the silence
while playing, it is much easier to accidentally run your amplifier beyond the reasonable limits set by
the manufacturer than when using a real speaker cabinet with it. This can lead to faster tube wear
and, in some cases, to more serious inconveniences.
When first testing the amplifier at high volume, monitor the color of the
tubes and the general state of the amplifier. Red-glowing tubes or any
appearance of smoke are signs of a problem that may result in partial or
complete destruction of the amplifier.
Keep in mind that the “sweet spot” - the perfect running point of the amplifier, the one that will give
you the tone you’re looking for - is rarely obtained at maximum volume. In addition, the volume
control of the amplifier is usually logarithmic, which means the volume goes up quickly on the first
half of the potentiometer rotation, reaches its maximum at 12 o’clock, and doesn’t change much
beyond this point. Therefore, you can reach the maximum volume of your amplifier even if the
volume potentiometer is not set at maximum.
By reaching the maximum output power of your amplifier, you will hear a lot of distortion, which may
not sound as well as you may hope. In fact, most amplifiers sound rather poorly at maximum volume.

2018/07/25 19:55 7/32 Torpedo Live User's Manual
User's manuals - http://wiki.two-notes.com/
Always keep in mind that your amplifier may not have been conceived to be used at maximum
volume for a long period of time. Running an amplifier at high volume will cause premature wear of
the tubes and possible malfunctions or damages at the output stage.
The fact that the volume control of your amplifier is not set at maximum
doesn’t mean your amplifier is not running at maximum volume. A good
habit is to keep the usual volume setup you would use in rehearsal or on
stage, rather than just following what the volume potentiometer indicates.
3 Is the use of a loadbox totally silent?
We usually talk about “silent recording” when a loadbox is involved. If we compare the loadbox
solution to a traditional cabinet miking solution, it is obviously A LOT quieter. Noises that you may
have not been able to hear before due to the volume of the speaker cabinet will now be more
apparent. Here are a few of those sounds that you might have to take into account:
• Your guitar or bass strings can be heard. If you are not used to this, it could be initially distracting,
depending on your environment.
• You may hear some noise coming out of your Torpedo Live when playing, like there is a tiny speaker
inside the box. This is perfectly normal and there is no reason to worry. The sound is produced when
power goes through the coil of the reactive load embedded on the Torpedo Live. The vibration is
related to what power comes out of the amplifier connected to the Torpedo Live and to the signal’s
frequency content (notes played are heard). Your ampli- fier, specifically the output transformer of
your amplifier, may also produce similar noise. Such noise is usually not heard, simply because it is
normally obscured by the sound coming from the loudspeaker.
• The Torpedo Live has a built in fan, as there is quite a lot of power dissipated into heat inside the
box. We selected a so called “silent fan”, but as it is running fast, it is never entirely silent. This said,
you can consider that, in normal use (hearing your guitar through monitors, or headphones), you can
barely hear the fan.
About the Torpedo Live
1 Introducing the Torpedo Live
Two notes Audio Engineering is proud to introduce the Torpedo Live, the optimized for live playing
version of the critically-acclaimed Torpedo hardware series. This product has been developed through
years of technical research, with great attention to the needs of guitarists, bassists and sound
technicians confronted with the challenges of miking instrument amplifiers, on stage or in the studio.
Our goal is to provide ease of use, reliability, versatility and above all, perfect audio quality.
The Torpedo technology was created as an answer to the high pressure musicians have to deal with:
lack of time, limited gear availability, loud amplifiers that can’t be played at desired volume, as well
as bulky and heavy cabinets to carry. In addition, many musicians are more comfortable with their

analog amplifier and effect pedals, and don’t want to perform using digital modeling systems, which
may compromise their playing style and sound.
For them, the Torpedo Live offers a “virtual” alternative to traditional miking, using a technology
derived from the convolution reverberation, to achieve a degree of realism never experienced
previously with simulators. The musician simply plugs the Torpedo Live in place of his cabinet,
connected to the speaker output of his amplifier, without modifying his usual settings (or connected
effect pedals as applicable).
The Torpedo Live comes with a large library of 32 cabinets and 8 microphones among the most
commonly used models in the world. You can also upgrade and add many other cabinets through “La
Boutique”, our online virtual cabinet store.The virtual miking is achieved by choosing one cabinet and
one microphone, and fine-tuning the position of the microphone in front of the cabinet. The Torpedo
Live allows the user to assume the role of the sound engineer in a professional studio.
The Torpedo Technology: to bring you realism and playing comfort, Two notes has developed a
unique technology based on an adaptation of convolution techniques. Starting with the measurement
of an actual cabinet + microphone setup, the Torpedo Live can accurately reproduce the system as it
was measured, as well as the microphone’s position in space. In order to take full advantage of these
digital algorithms, the highestquality audio design assures a perfect analog-to-digital conversion and
a huge dynamic range to retain the ultimate playing experience.
This product has been thoroughly tested in professional studio and stage environments and is the
alternative many musicians were waiting for, to achieve a professional sound capture of their
amplified instruments. The Torpedo Live will give you the elusive sound of the greatest recording
studios and producers, anytime, anywhere.

4 Only A Speaker Simulator?
The Torpedo Live is a standalone unit you can bring with you in any situation, whenever silent playing
is needed.
The role of the Torpedo Live is to replace the following elements of the traditional guitar or bass
setup:
the guitar/bass power amplifier
the speaker cabinet
the microphone
the microphone preamplifier
In order to provide a signal that is the closest possible to a traditional guitar/bass miking in a
professional studio environment.
The miking is achieved in 3 steps with the Torpedo Live:
Choose a power amplifier (or switch it off if you are using a loadbox), a speaker cabinet and a1.
microphone (Power Amp, Speaker, and Microphone sections)
Position the microphone inside the virtual studio (Miking window and parameters)2.
Shape the signal (Low Cut, EQ, Exciter and Comp sections)3.
At each step, Two notes Audio Engineering implements its know-how to offer the most advanced
simulations on the market and ensure absolutely realistic quality both for the musician (in terms of
playing sensation) and for the listener (in terms of sound quality). You can load up to 32 Two notes
cabinets in the Torpedo Live. Download the free Torpedo Remote software (Mac OS X and Windows
PC) from the Two notes Audio Engineering website, and you will be able to add or remove the stored
cabinets. There are currently more than 80 Two notes cabinets available in La Boutique and the Two
notes Store that you can try in real time and purchase with Torpedo Remote (requires a working
Internet connection).
4.1 Tube Stage Output
When using guitar/bass preamplifiers with some other speaker emulators, the musician may feel they
miss a power amplifier’s contribution to the overall sonic texture. Many musicians get their sound
from a particular use of that element and the Torpedo Live gives you the possibility to use it too. To
that effect, Two notes Audio Engineering has developed an original tube-stage modeling that gives

you a choice of 4 different tube models (6L6, EL34, EL84 and KT88) in Push-Pull (PP) in AB class, or
Single Ended (SE) in A class configurations. You can push this tube stage like a conventional amplifier
and look for that subtle yet particular distortion.
The Torpedo Live can be used as a super-DI for keyboards. The tube-amp simulation feature,
developed for guitarists and bassists, can also be a very interesting device to warm up the sound of a
synthesizer, an organ, or a digital piano.
4.2 EQ Section
When recording guitars or basses, it is common to apply a few effects to shape the sound before
sending it to a PA or a recorder. In the Torpedo Live you will find a simple but efficient EQ filter with
two modes, GUITAR or BASS.
4.3 Room reverb
One of the latest additions to our Torpedo firmware is a room reverb. When recording a guitar or a
bass, the room sound is really important, especially with distant miking. With the Torpedo Live, you
get the option to choose how the record room sounds!
4.4 The Torpedo technology, convolution and Impulse Responses
The impulse response (IR) of a system describes its behavior under the form of a very detailed filter.
The convolution technique uses IRs to simulate the behavior of particular systems, such as reverbs,
speakers, EQ…
It is the most accurate way to simulate sound signatures that are linear (i.e. without distortion) and
timeinvariant (i.e. without modulation, compression, hysteresis…). It is particularly well suited for
speaker miking simulation.
Two notes has developed a unique technology based on an adaptation of convolution
techniques. Starting with a measure of a real cabinet + microphone setup, the Torpedo
Live can accurately reproduce the system as it was measured, including the microphone’s
position in space by using IR synthesis.
4.5 3rd Party Impulse Responses
The Torpedo Live is capable of delivering the best guitar and bass tones by using the Torpedo
technology, but you can also embed impulse responses that you have purchased or downloaded for
free from 3rd-party developers, in WAV or AIFF formats. You can upload third-party IRs in the Torpedo
Live, by way of the free Torpedo Remote software.
4.6 Create Your Own IR's

software you will be able to capture your own cabinet + microphone setup and embed its sound
signature into the Torpedo Live.
Connecting the Torpedo Live
1 Overview
The Torpedo Live offers a solution for silent and quality sound pick-up in many situations. The
following illustrations show the most common situations theTorpedo Live has been created for.
1. Guitar/bass
2. Guitar/bass preamp
3. Torpedo Live
4. Audio interface
5. PC/MAC with Torpedo
Remote
6. Guitar/bass amp
7. Guitar/bass
8. Headphones
Even if it was design to go on stage, the Torpedo Live fits perfectly in a digital or analog studio, to
bring you the greatest tone with your amp, whatever the circumstances.
Please keep in mind that tube amplifiers have to be connected to an
appropriate load (cabinet or load box). Always plug the 8 ohms output from
your amp to the 8 ohms input of the Torpedo Live.

http://wiki.two-notes.com/ Printed on 2018/07/25 19:55
Always use a standard speaker cable between the amplifier speaker out and
the Torpedo Live SPKR IN. A speaker cable and an instrument cable may
look similar. You may have to open the jack connector and see for yourself:
the speaker cable is unshielded and carries the powerful signal through two
insulated conductors, the instrument cable is shielded and has only one
internal conductor. Using an instrument cable instead of a speaker cable
can cause significant damage to your amplifier, requiring service by a
technician.
2 In the studio
The studio setup shown here is an integration of the Torpedo Live in a usual Digital Audio
Workstation.
Plug your 8 ohms out on your amplifier to the SPEAKER input of the Torpedo Live. If you want to use a
preamplifier, plug its line output to the LINE INPUT of the machine. Connect the S/PDIF OUT of the
Torpedo Live to the S/PDIF IN of your audio interface. The sampling frequency can be set to 48KHz or
96KHz.
In this configuration the Torpedo Live is the master of the S/PDIF communication. This way, analog to
digital conversion is handle by the Torpedo Live, so you preserve all the tone coming from your

preamp/amp.
An S/PDIF signal contains two audio channels. The Torpedo Live is a mono unit, so we decided to give
a great feature : sending the WET signal (with miking simulation) through the LEFT channel and the
DRY signal (without miking simulation) on the RIGHT. This way you can record the dry and wet signal
simultaneously. Use the Wet signal to play as usual, and the DRY signal from the amp with a plugin
speaker simulator, such as our Torpedo WoS III plugin. You can decide to use both channels to carry
the Wet or the Dry signal, please read about the Output parameter in the Setup menu.
For a working S/PDIF connection, your audio interface must be in slave
mode, while the Torpedo Live is in master mode. Your audio interface must
handle 48KHz and/or 96KHz to properly work with the Torpedo Live. For
more information on your audio interface, please refer to its user manual.
Control the machine from your computer (PC Windows or Mac OSX) with the Torpedo Remote
software in USB. Create, save and load presets, load new cabinets or Impulse Response (IR) files.
Download the Torpedo Remote for free on the Two notes Audio Engineering website.
3 On stage
The analog I/O of the Torpedo Live offers great options on stage. For example, the analog output can
be connected to the front mixing console. Or plug headphones to the appropriate output and enjoy
playing your amp LOUD at home in total silence.
In the following figure, you will find a simple setup with an amplifier. The same can be done with a
preamplifier into the LINE INPUT of the Torpedo Live.

With a MIDI foot controller, you gain access to the presets navigation and even parameter changing in
real time. The Torpedo Live handles both Program Change et Control Change commands.
Playing in silence is a great feature, but at some point you have to listen to what you play! We
present a few options to use at home, in the studio or on stage:
Listen through the headphones out,1.
Listen on a guitar/bass cabinet plugged to the Torpedo Live THRU output,2.
Having a local monitoring system on stage, by duplicating the LINE OUPUT with a mixer,3.
Having in-ear monitors or wedge speakers controlled by a sound engineer.4.
The THRU, S/PDIF and LINE outputs can be used simultaneously.
When you plug a cabinet to the THRU output, the impedance of this cabinet
is the one that your amplifier sees. In other words, with a 4 Ohms cabinet,
you need to connect the 4 Ohms output of your amplifier. In this
configuration, the load box inside the Torpedo Live is disconnected. This
way, you can override the 8 Ohms only limitation of the Torpedo Live.

Configuring and using the Torpedo Live
1 The Torpedo Live interface
The Torpedo Live parameters are organized in menus, accessible by different push-buttons and knobs
as seen in figure 3.2.
Two 2-function rotary encoders: PRESET/PARAMETER, OUTPUT LEVEL/VALUE
Two push-buttons: SETUP and EDIT/HOLD TO SAVE.
One potentiometer: IN LEVEL.
When pushing a button or turning an encoder, you will see a parameter moving on the display.
2 Input gain control
The IN LEVEL potentiometer controls the input gain of the unit. The Torpedo Live being a digital
product, it is absolutely critical to avoid any saturation of the input signal and avoid the risk of
considerably reducing the audio quality. The input level is controlled by a potentiometer and is the
same for all presets. To get the best sound, try to have the same volume (or close) on all different
sounds coming to the Torpedo Live. This way you won’t have to change the input gain when switching
the channels on your amplifier. If you don’t have individual volume settings on your amplifier
channels, always do the gain setting with the loudest channel.
The input gain adjustment must be done with input signal present at the input selected (speaker or
line input). The input bargraph gives you a visual indication of the input signal amplitude. The upper
red led is on when there is saturation in the input stage: lower the volume of your amplifier output
and/or lower the input gain.
For optimum quality, we advise to keep the peak levels of the input signal
at a maximum of -12dB to -6dB on the bargraph.
3 Three menus: PERFORM, EDIT & SETUP
The Torpedo Live has three different menus, giving you access to different parameters:

First line: preset name, preset type (Arcade or Simulation) and number (between 001 and 128.)
Second line: Cabinet name (or IR name) and output volume (OUT LEVEL between -95dB and
+12dB).
In this menu you can navigate in the presets and set the output volume of the unit. You will be in this
menu when playing without editing or modifying any parameter. This way you can have a fast access
to the volume in case you have to quickly lower or increase the volume in any situation.
We recommend first to search for a preset close to the sound you have in mind, then tweak the
selected.
The preset name is limited to 32 letters or numbers. The authorized
characters are capital A to Z, 0 to 9 and space.
The various functions of the buttons in PERFORM menu are described in the following table:

preset modes: Arcade or Simulation. We borrowed the concept of Arcade VS Simulation from the
world of video games.
The Arcade mode is usually the easy way to, for example, drive a race car. You can hit obstacles,
other cars, you can still win the race. We recommend that for your first experience with The Torpedo
Live you start with the Arcade preset mode to get more familiar with the concept of virtual miking.
The simulation mode is not for beginners and requires more experience and knowledge about how
the car actually works, depending on many tiny but still important parameters (weather, type of tires,
track design…). In that preset mode you will gain access to the full list of parameter, to fine tune your
sound and make it perfect to your ears.

5.1 Arcade mode
In Arcade mode, the EDIT menu displays all the Arcade parameters, followed by the output volume of
the preset (this volume setting is saved with the preset, so you can adjust the levels in order for the
presets to be at comparable volumes).
Navigate through the parameters with the PARAMETER encoder. On a parameter page, you will see
the name of the parameter and its value. Change the value using the VALUE encoder.
In the simplified interface of the Arcade mode, each parameter actually controls one or several
parameters of the Simulation mode. For more details on the Simulation mode, see its description later
in this document.
The parameters of the Arcade mode are listed below:

Instrument: Guitar or Bass, determine the type of speaker cabinet you can access and select
later, the power amp type and parameters and EQ characteristics of the Contour parameter.
Speaker: Pick a speaker cabinet in the list, the list depends on the Instrument parameter and
the cabinets you actually loaded into you product’s memory.
Mic: Select a microphone in the list.
Room: Select one of the 8 rooms.
Power amp: In Guitar mode we selected an EL34 Pentode PP power amp and a 6L6 Pentode PP
power amp for Bass. Presence and Depth are fixed at 100%. The Power amp parameter
determine the amp master volume, from Cold to Hot. it can also be turned OFF.
Distance: In Arcade mode, Distance triggers both the mic placement algorithm (IR synthesis)
and the Dry/Wet of the Reverb. The farther the microphone is from the cabinet, the more you
will hear the reverb effect. The microphone is always in front of the cabinet.
Tone: Miking tone, from Dark to Bright. Triggers the Center parameter, moving the microphone
from the center of the speaker to the side.
Contour: EQ settings based on a loudness algorithm. Vintage will cut low and high frequencies
while Modern will emphasize them. The EQ parameters depends on the Guitar/Bass setting.
Level: Controls the level of the preset, from -95dB to 0dB.
5.2 Simulation mode
In Simulation mode, the EDIT menu features 4 modules (Power Amp, Miking, EQ and Reverb), followed
by the output volume of the preset (this volume setting is saved with the preset, so you can adjust
the levels in order for the presets to be at comparable volumes). Navigate through the parameters
and/or modules with the PARAMETER encoder.

A module is activated when it’s On, you can change the module state with the VALUE encoder. Once
the module is On, you gain access to the module parameters.
On a parameter page, you will see on the first line the module name, the parameter index and the
number of parameters of the module. On the second line you will find the parameter name and its
value. Change the value using the VALUE encoder.
5.2.1 Power Amp
When using the Torpedo Live with any kind of guitar/bass preamplifier, or even an electric piano or a
synthesizer, you need the color brought by the final stage of a traditional amplifier: the power
amplifier. Plug your device to the LINE input of the Torpedo Live and enjoy the typical sound of the
Two notes electrically accurate virtual tube power amplifier:
Power Amp: Activate the power amplifier simulation by turning “On” this parameter.
Model: Choose the amplifier topology (Push Pull or Single Ended) and the tubes type (6L6,
EL34, EL84 or KT88).
Volume: Set up the output volume of your virtual power amplifier.
Presence: This setting affects the tube stage frequency (loudness).
Depth: This setting affects the tube stage frequency (bandwidth).
Type: Select how the tube is used, either in triode or in pentode mode. Pentode mode has more
headroom and volume than triode.

In the “MIKING” menu, you take the place of the sound engineer. This is where you will find the
“sweet spot”, the perfect microphone position.
You have the option to choose whether you want to use the Two notes cabinets and microphones
combinations (Cab/mic) or a third party IR (User) selected from the installed IR’s in one of the 4
available User banks (of up to 128 files each).
In Cab/mic mode, you have access to 32 different cabinets, each cabinet can be miked with 1 of the 8
available microphones. Please refer to Part 7 to discover the microphones and cabinets library. The 32
cabinets that you will find offer the same list of 8 microphones, but you will discover that the cabinets
offered by the Capture Masters in La Boutique can offer a different set of microphones, to expand the
versatility of your Torpedo.
The next step is to place the microphone on the trapezoidal plan (you can see it in the Torpedo
Remote interface):
Distance: Determine the distance between the simulated cabinet and microphone. Placing a
microphone close to the cabinet will result in a precise sound with a large amount of proximity
effect (dependent on the chosen model of microphone). When you move the microphone away
