2. Recommendation on the proper use of a load box with a tube amplifier

2.1 What is a load box?

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 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 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 “load box” is used to describe any product that provides a load to the amplifier. The main parameter of the load box is its impedance, expressed in Ohms. An 8-Ohm load box 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 of the load box — otherwise overheating may cause damage, both to the load box and to the amplifier.

The Torpedo Captor X is a load box. This term indicates that the Torpedo Captor X 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 Captor X is a Reactive load. A Reactive load simulates the complex impedance of a real speaker.

Always connect the speaker output of your tube amplifier to an appropriate load (speaker cabinet or load box). The Torpedo Captor X is such a load. The Torpedo Captor does not need to be powered up to act as a load box. The maximum admissible power of the Torpedo Captor 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.

2.2 Which output volume for my amplifier?

The correct use of your amplifier with a load box 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. 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.

2.3 Is the use of a load box totally silent?

We usually talk about “silent recording” when a load box is involved. If we compare the load box solution to a traditional cabinet miking solution, it is obviously several orders of magnitude quieter, but you will still experience some minor sounds, noises, that have to be taken into account:

  • Your guitar or bass strings can be heard. This is obvious, but it can be disturbing, depending on your environment.
  • You may hear some noise coming out of your Torpedo 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 in the Torpedo Captor. The vibration is related to what power comes out of the amplifier connected to the Torpedo and to the signal’s frequency content (notes played are heard). Your amplifier may also produce similar noise, at the output transformer’s level. Such noise is usually not heard, simply because it is normally overcome by the sound coming from the loudspeaker.
  • The Torpedo Captor X embeds a 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 that fan.

3. About the Torpedo Captor X

3.1 Introducing the Torpedo Captor X

Playing your tube amp in a great sounding room with an exceptional choice of perfectly matched speaker cabinets and microphones is truly joyous and an unparalleled experience. The Torpedo Captor X is for tube amp lovers who crave this every time they play – no matter the environment. Play your tube amp at its sweet spot and control your volume with the attenuator, anywhere. You can even enjoy your 100 watt rig in silence with an immersive headphone experience. Fed up with lifting heavy cabinets, inconsistent sound and stage volume issues? Go direct to the PA and audio interface with studio-grade cabinet simulations. 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 these players, the Torpedo Captor X 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 Torpedo Captor X is the perfect line output everybody should have at the final stage of their pedalboard or after their amp section to send the sound directly to a PA or a recorder.

The Torpedo Captor X is a compact reactive load box, tube amp attenuator, miked cab simulator, IR loader and stereo expander for home, live and studio use.

The Torpedo Captor X comes with a large library of 32 cabinets and 8 microphones per cabinet among the most commonly used models in the world. You can also upgrade and add many other cabinets through the Two notes Store, our online virtual cabinet store. The virtual miking is achieved by choosing one cabinet and two microphones, and fine-tuning the position of each microphone in front of the cabinet. The Torpedo Captor X 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 Captor X 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 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 studios and stage environments and is the alternative many musicians are looking for, to achieve a professional sound capture of their amplified instruments. The Torpedo Captor X will give you the elusive sound of the greatest recording studios and producers, anytime, anywhere.

3.2 Only A Speaker Simulator?

The Torpedo Captor X is a standalone unit you can bring with you in any situation, whenever silent playing is needed or if you wish to control the level coming out of your cabinet.

The role of the Torpedo Captor X is to replace the following elements of the traditional guitar or bass setup:

  • 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 Captor X:

  1. Choose a speaker cabinet and a microphone
  2. Position the microphone inside the virtual studio
  3. Shape the signal (EQ, Enhancer, Twin Tracker,Reverb)

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 Captor X. 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 300 Two notes cabinets available in the Two notes Store that you can try in real time and purchase with Torpedo Remote (requires a working Internet connection).

4.1.3 Virtual Cabinet / IR loader mode

4.2 Creating a preset with a Virtual Cabinet

A preset contains:
- a cabinet
- two microphones and their positions in regards to the cabinet
- effects settings (eq, enhancer, Reverb, Twin Tracker)
- levels for left and right outputs

4.2.1 Cabinet choice

cabinet_rack.jpg To create a preset, first select a cabinet. Torpedo Captor X comes with a collection of 32 Virtual Cabinets already loaded in the internal memory. Click on the blue screen or the arrow to access the list of cabinets in your Torpedo Captor X.

4.2.2 Microphone choice

All Two notes Virtual Cabinets come with a dedicated collection of 8 microphones. Positioning

mic_position.jpg You can move the microphones anywhere in the trapezoid highlighted area, in front or at the back of the cabinet. Select Mic A or Mic B with the switch and move the microphone with your mouse (when using a computer) or your finger (when using a mobile device) by pressing on the mic or the mic stand. Mic A / Mic B

mic_a.jpg For each microphone, you have the same settings: the fader to set the volume level, front/back switch to place the mic in front or at the back of the cabinet, Bypass button to send an unprocessed signal(B), Mute button (B), Phase button, Distance and Axis knob to position the mic.

4.2.3 Shaping your tone

Torpedo Captor X has many tools to polish your sound before going to the PA or the audio interface. Noise gate

The noise gate is very useful if you are using a high gain amp and want to keep your signal quiet when you are not playing. The threshold sets the level where the noise gate is active: if you are over this level the noise gate is off, if you are under, the noise gate is active. The Learn button automatically sets the Threshold level. Keep your guitar volume to the maximum, mute your strings with your hand and click on the Learn button. The Noise Gate will listen to the input sound and set the threshold level accordingly. Make sure to mute your strings for at least 3 seconds so the Learn can properly analyse the input signal. EQ

The EQ section has 3 modes of operations: guitar, bass and custom. Guitar mode: 120Hz, 360Hz, 800Hz, 2000Hz, 6000Hz (centre frequency of each band from the lower to the highest). You can adjust the gain for each band with a range of -20 dB to +20dB.

Bass mode: 50Hz, 120Hz, 360Hz, 800Hz, 4000Hz (centre frequency of each band, from the lowest to the highest). You can adjust the gain for each band with a range of -20 dB to +20dB.

Custom mode : Instead of having fixed frequencies to work with, the Custom mode gives you access to a 6 band semi parametric eq (12 dB per octave slope). The bands are as follow:

  Low Cut: low cut, 10 - 500Hz
  Low: low shelf, 60 - 240 Hz, +/-20dB
  LMid: peak, 180 - 720 Hz, +/-20dB
  Mid: peak, 400 - 1600 Hz, +/-20dB
  HMid: peak, 1 - 4 kHz, +/-20dB Enhancer

the Enhancer is a combination of dynamic and tone-shaping tools, tailored for your guitar, and bass. The Dry/Wet allows you to balance the cab sim signal and the processed signal by the Enhancer. At zero (knob turned all the way down), only the cab sim signal is heard. At halfway position, the level of the cab sim signal is equal to the level of the enhancer. At full (knob turned all the way up), you are only hearing the signal processed by the Enhancer. Body is a compressor with a high-pass filter. It only affects the low-mids and above frequencies of the signal. Body will render your tone fuller and more present. Thickness and Brilliance emphasize the low end and high end of the tone, respectively. Thickness is centered at 400 Hz in Guitar mode and 150 Hz in bass mode. Brilliance is centered at 1500 Hz in Guitar mode and 2000 Hz in bass mode. Both Thickness and Brilliance have a gain range between 0 and +15dB. Reverb

There are 12 room reverbs and one full custom reverb in the Torpedo Captor X. When using the Custom Reverb, you have access to the following parameters: - Size: adjusts the size of the room. From tiny to gigantic. - Echo: adjusts the level of the reflections. - Color: adjusts the tone of the reverb. From dark to bright.

There is also a switch to change the acoustic characteristics of the reverb: - Room: for more early reflection, and more brightness - Ambience: has more low end, with more subtle early reflections.

4.3 Creating a preset with a 3rd-party IR

The Torpedo Captor X can load up to 512 IRs. All imports of IRs are done by Torpedo Remote through the IR manager. Torpedo Captor X can read IRs that are 40, 100 or 200 ms long. If the IR is longer it will be truncated by Torpedo remote to the selected length.

4.3.1 IR choice

To use custom made IRs with Torpedo BlendIR or 3rd-party IRs, you need to select IR Loader mode in Torpedo Remote. The window will have a similar layout to the Virtual Cabinet. you can load to IRs per channel, and have the same control on each channel: mute, bypass, phase, and volume with the fader.

You will then be able to shape the tone with the EQ, the Enhancer and the Reverb.

4.4 Output Routing

The Torpedo Captor X allows for different routings of the XLR outputs. They can be set to STEREO or to DUAL/MONO. To change routing, click on the purple button above the output level knob.

4.4.1 Stereo Routing

In Stereo, both outputs send the same cab sim signal. In Stereo, you have access to the Twin Tracker and all reverbs are stereo. The Twin Tracker

Twin Tracker is an automatic double tracker. Your mono amp sound is routed to the left output and Twin Tracker creates another track (a virtual guitarist) on the right channel in real-time. The slight differences in timing and attack contribute to a beefed-up tone and massive sound.

It has 2 parameters: - Balance: sets the level of the twin tracker. If turned all the way down, you will only hear the left output of the Torpedo Captor X. - Tightness: sets the delay of the virtual guitarist. The latency can reach 70 ms. (if you plug only the right XLR output and notice an enormous amount of latency while playing, check that you are not in Stereo routing with the Twin Tracker on and that the Tightness parameter is at its highest point).

The Twin Tracker is only available in Stereo routing. When on, the Width of the reverb is automatically set to 100%. Stereo Reverb

In stereo, you can set the stereo size of any rooms with the Width parameter: from mono (knob turned all the way to the left) to full wide stereo (knob turned all the way to the right). Space knob assignement

On the front panel, the SPACE knob allows you to control one parameter on the fly. You will assign the behaviour of SPACE in Torpedo Remote, through the purple button below the SPACE knob in the software. Here are the different assignment possibilities: - ST. EXP. : there are two possible behaviours.

           1. Twin Tracker is OFF. The SPACE knob is assigned to the width of the reverb.
           2. Twin Tracker is ON. The Space knob is assigned to the Tightness of the Twin Tracker. The Width of the reverb is automatically set to 100%. 

- D/W : The SPACE Knob is assigned to the Dry/Wet level of the reverb.

4.4.2 Dual Mono Routing

This routing allows you to send independent signal from each XLR outputs. You will be able to set a different EQ and dry/wet reverb level to the right XLR output. The layout of the Torpedo Remote will show you an addtional EQ next to the right output fader. Additional EQ

You can set a different EQ on the right output. All the parameters of the EQ are the same as the general EQ. See description before for each band and setting. Dry/Wet reverb setting

You can set 2 different Dry/wet reverb levels for each XLR outputs. The parameter in the reverb rack is only editable through Torpedo Remote. Depending of the SPACE knob assignment, the Dry/wet in the reverb rack will affect the Left or the Right XLR output. Space knob assignement

It is possible to set different behaviours to the SPACE Knob: - D/W: the SPACE knob controls the Dry/wet Reverb level for both XLR outputs. - D/W L: the SPACE knob controls the Dry/wet Reverb level for the Left XLR outputs. - D/W R: the SPACE knob controls the Dry/wet Reverb level for the Right XLR outputs. The "Bypass Torpedo Processing"

When the B button is activated on the Right output channel, the whole Torpedo process is bypassed. The Right XLR output is sending the dry amp sound. This is an ideal setup when you wish to record your amp. You will record the full cab sim signal from the Left XLR output, while at the same time recording the dry amp sound from the Right XLR output.

5.5.1 Two notes cabinets

You can preview any cabinets that are not in your license when using the Remote. This is why when you browse the cabinets in the Remote the list is way bigger than what you have in your license or in your Torpedo Captor X.
torpedo_cabm_interface_6.jpg You will see 3 types of icons in front of the names of the cabinets :

torpedo_cabm_interface_icon1.jpg Cabinets which are on your Torpedo unit.
torpedo_cabm_interface_icon2.jpg Cabinets which are on your licence loaded in your computer
torpedo_cabm_interface_icon3.jpg Cabinets which you do not own but can preview before buying them on the Two notes Store.

When you are previewing a cabinet that is on your computer (which means that you own it and it is in your license stored in your computer), the Remote needs to load the cabinet first so you can edit all the parameters. As you are previewing, you will only have access to one microphone for the cabinet. Audio is still going through normally through the pedal, so you can use the Captor X as you would normally.



This box allows you to transfer the cabinet you are previewing from your computer to your Captor X (as long as you have memory slots available in your unit).

When you are previewing a cabinet that you do not own, random silences are inserted and you have access only to one mic to preview the cabinets.


You can add the previewed cabinet in the Store Cart by clicking on the trolley with the plus sign :


This operation can be repeated for any cabinets, and when you want to finalize the cart and buy the cabinets you want, you click on the trolley with the green tick and you will be taken to the online Two notes Store. The trolley with the minus sign allows you to remove the current cabinet from the cart :


No billing or information on the payment method is stored on the Remote, so as to ensure maximum security.

5.5.2 .tur files

.tur are proprietary files created with the Two notes Audio Engineering Torpedo BlendIR software. The software is available for download from the Two notes Audio Engineering website. With Torpedo BlendIR you are able to use the Torpedo technology to capture the sound signature of your own cabinet and microphone in the deepest details.

To load a file into the Torpedo, place it in the default Impulse directory, or select the directory containing the files through Torpedo Remote (this can be done in the menu). You can then load the files into the Torpedo through the Memory Manager or directly listen to them through the main Remote window.

Please note that with .tur files you do not have access to the microphone positioning parameter.

5.5.3 3rd-party IR files (in .wav or .aiff format)

Torpedo Captor X complies with third-party Impulse Responses (IRs) in .wav or .aiff format, 16 or 24bits, 44.1Khz to 96Khz. With Torpedo Remote

To load a file into the Torpedo Captor X internal memory, use the IR Manager window.

The left panel is the files on your computer. You can browse the folders where you have stored your IRs. The right side represents the IR files that are loaded in the Torpedo Captor X. You can drag and drop the IRs from the computer (left) to the Torpedo (right). If you wish to free memory slots in the pedal, you can drag and drop the IRs to the bin at the bottom.

You have access to some options to modify the IR file for the transfer:

  1. IR length: increasing the IR length will improve the resolution of the Torpedo processing (more precision will lead to better accuracy in the low end). Please note that a 40ms IR will take 2 slots in your Torpedo Captor X' s internal memory.
  2. IR offset: you have access to 3 options that will change the way the IR file will be processed:

* Min Phase: an algorithm will move the samples in the file so it will sound in phase with any other IR file (provided you use that function to transfer the other files as well).

* Min. IR Latency: the file is cut so there is no silence before the first sample, this can lead to a change in the sound but your latency will be minimal.

* Original: the samples in the file remain untouched. You may experience phase cancellation issues with mixing it with other IR files.

Note: with 3rd-party files, you do not have access to microphone positioning parameters.
