EFFECTS LOOP RETURN
1/4”input jack for returning signals from external low-level effects or signal processing equipment. This is a
switching jack: Inserting a plug into this jack will break the signal path from the EFFECTS SEND (#25) jack.
If the effects loop is used, then it will automatically be on. However, a footswitch can also be used to
bypass the effects loop-- see below.
FOOTSWITCH JACKS
Provided for the connection of the footswitches using TRS (Tip, Ring, Sleeve) jack plugs.
Top jack (CHNL/BOOST):-
‘Ring’ (Left on a Peavey footswitch): Selects between the preamp channels.
‘Tip’ (Right on a Peavey footswitch): Selects the ‘CRCH’ (crunch) boost on the RHYTHM channel.
Bottom jack (RVRB/LOOP):-
‘Ring’ (Left on a Peavey footswitch): Turns the effects loop on or off.
‘Tip’ (Right on a Peavey footswitch): Turns the reverb on or off.
Peavey footswitches are available with and without LEDs to indicate current settings. Please refer to www.
peavey.com or customer services for more information and product codes.
To switch the channels and boost function using the footswitch, the relevant front panel switches need to
be set to their “IN” position.
When using a footswitch, always insert the plug fully (second click) into the FOOTSWITCH jacks to ensure
proper operation.
MICROPHONE SIMULATED USB AUDIO RECORD OUTPUT
The USB Record Output requires no additional drivers – just plug a standard USB 2.0 cable into your
computer and it will detect it as an audio device. Open your favorite recording program and start
recording. The output is derived from the MSDI™ so will sound great right into your computer.
This can be used in any setting of the POWER OUTPUT (#18) or SPEAKER DEFEAT (#21) switches and there
should be little comparative differences in USB audio level. Therefore a good strong signal can still be
recorded while the amp is set to 5% power or even silent.
The actual level of the signal from the USB out will be dependent on the settings of the controls. However
each unit has been calibrated so that a very wide range of sounds and levels will all fit within the USB
headroom. Like with any recording, especially digital, the actual recording levels should be set so as to
prevent any unwanted distortion.
* Power tubes
Warning!!! If the power tubes (EL84) are changed, then the amplifier should be re-biased. We have
designed them so this is a fairly quick and easy procedure, but this should be carried out by a qualified
and competent technician/engineer. This is not only due to safety, but also to ensure the user gets the
best sound and longevity from their new tubes. Incorrectly biased power tubes can either sound dirty and
lifeless or burn out unnecessarily quickly.
