The speaker output will always behave normally. As an

added bonus, some users will find this useful for "wet/

dry" setups in which they send a signal that utilizes

reverb to FOH (front of house), while playing through a

dry speaker.

The Ground Lift switch should be set to ground (pushed

in) for best results. However, if this produces a buzz or

hum because of ground loops between the amplifier

and the audio interface, press the ground lift switch to

eliminate noise.

Note: The level control under the headphone jack

controls your output level/volume to the XLR outputs.

The clip LED will illuminate if the signal is set too high.

BIAS TEST POINTS

This amplifier is designed to allow the user to set the

bias of the power tubes without removing the chassis

from the head shell. The power tube bias for the pair

of tubes needs to be set according to the tubes being

used. Always use a matched pair of power tubes in

your amplifier. (See Section "Tubes & Bias" Page 11 for

more information)

USB-B JACK

The USB Jack will connect your computer via the

provided USB cable to your D40 to use Two-notes

Remote software, which can be used for deep editing

of presets, creating new ones from scratch, or loading

third-party Impulse Responses!

REVERB LEVEL CONTROL

The reverb level control increases the intensity of the

reverb effect in your sound when the reverb switch on

the front panel is activated. Turn the knob clockwise to

increase reverb and counterclockwise to decrease the

Effect.

REVERB DECAY CONTROL

The reverb decay control will set the amount of

reflections from the reverb circuit. Increase the number

of reflections and the amount of time it takes to fade

out by turning the control clockwise. Turn the knob

counterclockwise to reduce this effect.

WATTAGE SWITCH

This latching push switch sets the overall power output

of the amplifier between 10 watts and 40 watts.

FX LOOP SEND & RETURN JACKS

The D40 features a high-quality buffered, instrument-

level, 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. The output jack on the effects

unit (or last pedal in your chain, if you are connecting

multiple effects in series in the loop) will then connect

back to the return jack on the amp.

Your effect is now part of the signal chain, verify that

your levels are set accordingly to the effect, so you

have a strong signal being sent to the amplifier, then

adjust the volume control on the amplifier to your

requirements.

INTERNAL LOAD SWITCH

This latching push switch engages the internal load

or allows a real speaker cab to be used when set

accordingly. If there are no speaker cabs connected to

the speaker jacks on the amplifier, the internal load will

be engaged automatically.

CABINET LIGHTING

The cabinet lighting jack on the rear of the amplifier

is used to connect the amp 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 amplifier to the cab lighting connector on

the cabinet.

IMPEDANCE & SPEAKER JACKS

The amplifier must always be connected to a speaker

cabinet or load when it is powered up and set to have

the internal load disengaged.

This amplifier can be used with cabinets that provide a

load of 4, 8 & 16 ohms. Because the amplifier provides a

number of speaker jacks with different impedance options,

it can also power 2 cabinets directly from the amplifier.

The speaker jacks must be used correctly for the

impedance to be matched between your amp and the

cabinets being connected.

Most setups are simple, one cabinet plugged into

the amp, select the impedance to that marked on the

cabinet & you're ready to go!

However, when it comes to adding more cabinets to

the rig, more care must be taken to prevent damage.

Most rigs will not utilize more than 2 cabinets, so we

won't go beyond 2

cabinets here.

Selects between 4 & 8 ohm impedance. This should be

set to 4 ohms for normal operation with D40's combo

speaker.

Some examples:

• 2 - 8 ohm cabinets would be plugged into the

two 4 ohm speaker jacks (one per 8 ohm cab)

located on the back of the amplifier.

• 2 - 16 ohm cabinets would be plugged into the

two 8 ohm speaker jacks (one per 16 ohm cab)

located on the back of the amplifier.

• 2 - 4 ohm cabinets cannot be run in parallel

with this amplifier. This will cause damage.

Note: No damage will result when running the amplifier

set at a lower impedance (Ex: 4 ohms) into a cabinet

rated at a higher impedance (Ex: 8 Ohms). However the

opposite will cause damage to the output transformer

or other components & it is suggested that the amplifier

never be run into a lower load.

MIDI CONNECTION

The MIDI IN connection is for external equipment

connections when your rig necessitates control of your

Revv with third-party gear.

The MIDI through jack allows for the connection of

additional MIDI devices in your signal chain, in addition

to your Revv.

Note: See "MIDI" on page 13 for more information.

POWER TUBE FAULT FUSES

The power tubes each have their own fuse. Should a

power tube fail, the fuse will blow & take the tube out of

service. This has the benefit of protecting the amplifier,

but will result in a loss of normal operation.
