Part 2
Warning regarding 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 recommended to 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 partial or complete destruction of the output stage
of the tube amplifier.
Most tube amplifier makers protect their products with fuses or other protection systems, but some amplifiers
still remain not or 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 load box).
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 fits any product embedding a load. The main parameter of the
load box is its impedance, expressed in Ohms. An 8 Ohms load box has to be plugged to the 8 Ohms speaker out
of the amplifier. The power sent to the load is changed into heat, so please follow the cooling recommendation
of the load box, otherwise overheating may cause damage, both to the loadbox and the amp.
The TORPEDO Live is a 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.
The embedded load in the TORPEDO Live is a reactive one: it embeds a specific circuit to simulate the
complex impedance of a real speaker. This kind of system is widely used in the industry to silently test amplifiers.
Always connect the speaker out of your tube ampilifier to a proper load
(speaker cabinet or load box). TORPEDO Live, once powered up, is such a
load. Please note that you always have to power up the TORPEDO Live before
your amplifier.
Two Notes Audio Engineering TORPEDO Live 11

Warning regarding the proper use of a loadbox with a tube amplifier
2 Which output volume for my amplifier ?
The correct use of your amplifier with a loadbox requires some precautions. Because of the fact that you may
be playing "silently," it is much easier to accidentally run your amplifier beyond the reasonable limits set by the
manufacturer than when you are using an actual speaker cabinet. This can lead to faster tube wear and, in
some cases, to more serious inconveniences.
During the first tests at high volume on the amplifier, monitor the color of the
tubes and the general state of the amplifier. Red-glowing tubes or any appear-
ance of smoke are signs of a problem that could lead to 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 are looking for — is rarely obtained at maximum volume. In addition, the volume control of the amplifier
is usually logarithmic, which means that the volume goes up quickly on the first half of the potentiometer’s
rotation, reaches its maximum at 12 o’clock, and will not change much beyond that 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 good as you could hope. In fact, most amplifiers do sound rather poorly at maximum volume. Always
keep in mind that your amplifier may not have been conceived to be used at maximum volume for a long
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 does
not 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.

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 re-
search, with great attention to the needs of guitarists, bassists and sound technicians confronted the challenges
of miking instrument amplifiers, on stage or in 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 45 cabinets and 8 microphones among the most commonly
used models in the world. The virtual miking is done by choosing one cabinet and one microphone, and fine-
tuning the position of the microphone in front of the cabinet. The Torpedo allows the user to assume the role of
the sound engineer in a professional studio.
The TORPEDO Technology : to give you realism and playing comfort, Two Notes developed a unique technol-
ogy 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 position in space. In order to take full advantage of these digital algorithms, the highest quality
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 professional sound capture of their amplified instruments. The TORPEDO Live
will give you the elusive sound of the greatest recording studios and producers, every time, everywhere.

4 Only a speaker simulation ?
The TORPEDO Live is a standalone unit you can bring with you in any situation, when 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
to provide a signal that is the closest possible to a traditional guitar/bass miking in a professional studio envi-
ronment.
14 Two Notes Audio Engineering TORPEDO Live

About the TORPEDO Live
The miking is achieved in 3 steps with the TORPEDO Live:
1. choose a power amplifier (or switch it off if you are using a loadbox), a speaker cabinet and a microphone
(Amplifier, speaker and microphone section),
2. place the microphone in the virtual studio (Miking window and parameters),
3. shape the signal (Low Cut, Eq, Exciter and Comp sections).
With each step, Two Notes Audio Engineering implements its know-how to propose the most advanced sim-
ulations on the market and ensure a total realism both for the musician (playing sensations) and the listener
(sound quality).
You can embed up to 32 Two Notes cabinets in the TORPEDO Live. Download the free TORPEDO Remote
software (Mac OSX and Windows PC) from the Two Notes website, you will be able to add and remove the
embedded cabinets, there are currently 45 Two Notes cabinets, and new free cabinets available directly from
you TORPEDO Remote software.
4.1 Tube Stage Output
When using a guitar/bass preamplifier with other speaker emulators, the guitarist/bassist may miss the power
amplifier’s contribution to the overall sonic texture. Many musicians get their sound from a particular use of this
element and this possibility is present in the TORPEDO Live.
To do this, Two Notes developed an original tube stage modeling, giving you the choice between 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 this 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, is also very interesting to warm-up the sound of a synthesizer, organ or a digital piano.
4.2 Section EQ
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 The Torpedo technology, convolution and Impulse Responses
The impulse response (IR) of a system describes it behavior under the form of a very detailed filter. The convolu-
tion technique uses IRs to simulate the behavior or 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 time-
invariant (i.e. no effect like modulation, compression, hysteresis...). It is particularly well suited for speaker miking
simulation.
Two Notes developed a unique technology based on an adaptation of convolution techniques. Starting
with a measure of a real cabinet + microphone setup, the TORPEDO TORPEDO Live can accurately reproduce
the system as it was measured, as well as the microphone position in space by using IR synthesis.
4.4 Third 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 you can purchase or download for free from 3rd party developers,
in WAV or AIFF formats.
You can upload up to 512 third party IRs in the TORPEDO Live, using the free Torpedo Remote software.
4.5 Create your own IRs
Download the free TORPEDO Capture software from the Two Notes website. With this software you will be able
to capture your own cabinet + microphone setup and embed its sound signature into the TORPEDO Live.

2Guitar/bass preamp 4Audio interface 6Guitar/bass amp 8Headphones
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 appro-
priate load (cabinet or load box). Always plug the 8 ohms output from your
amp to the 8 ohms input of the TORPEDO Live.
Two Notes Audio Engineering TORPEDO Live 17

Connecting the TORPEDO Live
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 PI-101 WoS !!
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 infor-
mation 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 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 in a total silence, at home.
On the following figure you will find a simple setup with an amplifier,the same can be done with a preamplifier
in 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 preset a few
option to use at home, in the studio or on stage:
1. Listen through the headphones out,
2. Listen on a guitar/bass cabinet plugged to the TORPEDO Live THRU output,
3. Having a local monitoring system on stage, by duplicating the LINE OUPUT with a mixer,
4. Having in-ear monitors or wedge speakers controlled by a sound engineer.
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.
