1.0 safety instructions & warnings read before connecting This product has been built by the manufacturer in accordance with IEC 62368-1 and left the factory in safe working order. To maintain this condition and ensure non-risk operation, the user must follow the advice and warning comments found in the operating instructions. The unit conforms to Protection Class 1 (protectively earthed).
• Remove the AC power cord from the amplifier when changing tubes, fuses or when moving the amplifier. Always replace fuses with the correct type and rating. • The AC power cord should be removed from the outlet when left unused for long periods or when there is risk of electrical storms. • To reduce the risk of electrical shock, the grounding of this product must be maintained.
***This symbol, wherever it appears, alerts you to the presence of uninsulated dangerous voltage inside the enclosure – voltage that may be sufficient to constitute a risk of shock. ***This symbol, wherever it appears, alerts you to important operating and maintenance instructions in the accompanying literature. Read the manual. ***This symbol, wherever it appears, tells you: Take care! Hot surface! To prevent burns you must not touch.
1.1 set up & power up It is very important to place the amplifier in a dry location that provides 4-6” of space between the rear of the amplifier and anything in the area that has been designated for the amplifier. Tubes produce heat, and anything flammable should be kept away. Verify that the heat vent is free from obstruction so that the heat produced by the tubes can escape from the interior of the amplifier. Make sure that the power and standby switches are in the off (down) positions.
Once all your connections are made, move the power switch to the On position and give the tubes at least one minute to warm up. Now is a great time to begin setting all controls while we wait. We recommend setting the master volume and gain controls to the lowest setting or zero (fully counter clockwise) and all treble, mid and bass controls to the 12 o’clock positions to begin.
2.0 Front Panel Layout Input - ¼” Instrument cable input. Gain Control - The gain control will add body and drive to your signal. It is a push/pull switch as well which when pulled out will give you a more distorted tone. This will give you the ability to find many different sounds and character in the range of the gain control.
Volume Control - The volume control drives the power amplifier producing your speaker output volume, but it also provides signal to the Two notes technology when the Pre/post switch is set to post. This will allow you to control the volume from your speakers but also control the input signal to the Two notes tech.
Note: While you should not feel obligated to use this, this can be a powerful tool for advanced users looking to get a radically different sound out of their D20 for example when recording or sending your signal direct to front of house live. Headphone Jack - The headphone jack on the D20 comes directly from the Two notes output! This allows you to use the amplifier with any of the selected virtual cabinet settings through your headphones.
3.0 Rear Panel Layout Mains Power Connector - When plugging the amplifier into the mains A/C wall receptacle, always make sure the amplifier power and standby switches are in the off position. The Required voltage and fuse ratings are marked on the amplifier underneath the mains input. Verify that they are correct for your electrical mains supply before plugging it in.
Cabinet Lighting - The cabinet lighting jack on the rear of the amplifier is used to connect the D20 to Revv speaker cabinets. Because the Revv badge on our cabinets lights up, you can illuminate the cab badge with this jack. Simply use the 4 pin Din cable provided with all Revv cabinets and connect the D20 to the cab lighting connector on the cabinet. MIDI In - The MIDI In jack is used exclusively with the Two notes Torpedo Embedded.
FX Loop Send and Return Jacks - The D20 features a high quality buffered FX loop, the send and return jacks connect to any pedals or effect units you may want to use with the amplifier. Let’s go through it step by step, just in case you have never used an effects loop and don’t know how to hook it up. The send jack will need to be connected to the input jack on your effects unit.
4.0 Tubes & Bias Power Tubes - The Revv D20 has been designed to use 6V6GT power tubes in the power section, and it is recommended that Revv 6V6GT power tubes be used whenever replacement is necessary for optimal performance. Preamp Tubes - The D20 amplifier uses 12AX7 preamp tubes in tube positions V1 and V2 positions. Preamp tubes do not need to be biased and usually have a long life, unlike power tubes. However it is possible for a preamp tube to become faulty at any stage of its rated lifespan.
Procedure: 1) If you are simply checking the bias, use your multimeter in the bias test points to verify that the tubes are at the recommended bias setting. If the bias setting needs to be adjusted or new tubes were installed, remove the D20 top lid to access the tubes and bias control trimmer. 2) If you are changing tubes, change them now, make sure that the power cable is unplugged from the amplifier. 3) Once the tubes are replaced, or you are ready to adjust the bias.
5.0 MIDI The D20 amplifier is equipped with MIDI for control of the embedded Two notes Torpedo. Program Change - Each preset on the D20 has a single program number. Preset 001 is recalled with MIDI PC 1, and you can recall the 128 virtual cab presets with MIDI PC 1 through MIDI PC 128 in this manner. Control Change - For very specific uses Control Change signals may be appropriate.
5.1 MIDI CC Commands The following table indicates the Control Change numbers for every parameter, as well as their range and behavior. This table is valid for firmware version 4.

6.0 Balanced Out - XLR The balanced out XLR connector on the rear of the amplifier is a direct output from the embedded Two notes Torpedo and not direct from the tube amplifier output itself. The purpose of this output is to be used with audio interfaces to exclude the use of an actual speaker cabinet, using virtual cabinets instead. Note: The reverb or other effects that the Two notes Torpedo provides will only be available through the output at the headphone or XLR jack and not a real cabinet.
7.0 USB The D20 can be connected to Two notes Remote software in order to manipulate all available settings and change the presets found on the front knob of the amplifier. This is via the USB port. You can find the Remote Software for the D20 here: https://www.two-notes.com/downloads Once you connect your D20 to the computer using the provided USB cable, your computer will start recognizing the D20. This may take a couple of minutes.
8.0 Reactive Load The D20 comes with a built in reactive load to allow you to play without the need for a speaker cabinet. On the rear of the amplifier there is an internal load/speaker switch to switch between the speaker cabinet and the reactive load. Depending on what you need, you can switch between the two on the fly.
