EFFECTS SEND LEVEL
This calibrated (-20dB to 0dB) control sets the level of signal being sent to external effects and/or signal pro-
cessors. Clockwise rotation increases the amount of signal being sent; counterclockwise rotation decreases
the amount. For unity gain, set both to 0dB (max) setting. Boost can be achieved by cutting Send or Return
levels. The fact that both knobs cut allows for higher "level" settings on effects. All of this can be used to bet-
ter optimize noise and avoid any chance of unwanted clipping in a given effect.
EFFECTS SEND / EFFECTS RETURN
These 1/4" mono (TS) jacks allow signal to be sent to and returned from external effects and/or signal proces-
sors. Using shielded cables with 1/4" mono (TS) phone plugs, patch from EFFECTS SEND to the input of the
external device, and from the output of the external device to EFFECTS RETURN. If the footswitch is used, the
EFFECTS SELECTOR switch must be depressed to activate the effects loop. See the FOOTSWITCH section of this
manual for explanation of switch operation (page 9).
EFFECTS RETURN LEVEL
This calibrated (-10dB to 0dB) control sets the level of signal being returned from external effects and/or sig-
nal processors. Clockwise rotation increases the amount of signal being returned; counterclockwise rotation
decreases the amount.
REMOTE SWITCH
This eight-pin DIN connector is provided for the connection of the remote footswitch. You must use the in-
cluded eight-pin cable, as it supplies power to the footswitch. The Butcher can also be controlled remotely via
MIDI using a standard five-pin MIDI cable. For a complete description of the MIDI commands, please refer to
page 12 of this owner's manual.
MSDI
™
Microphone Simulated Direct Interface. Peavey's exclusive MSDI simulates the sound of a microphone near
a real speaker cone, allowing the user to send a direct signal to the mixing console with a miked-cab sound.
This is a non-powered output and safe for use with any mixing console. The MSDI also features a TONE control,
GROUND LIFT and LEVEL control, enabling the front-of-house engineer to alter the tone to what is required for
the best sound. The MSDI is a passive circuit that does not clip.
CABINET IMPEDANCE SWITCH
This three-position switch allows appropriate selection of speaker cabinet impedance. If two enclosures of
equal impedance are used, the switch should be set to half the individual value. For example, two 16-ohm en-
closures necessitate an 8-ohm setting, while two 8-ohm enclosures would require a 4-ohm setting. Minimum
speaker impedance is 4 ohms. When the amplifier is set to half-power mode, the impedence selector uses the
bottom row on the switch to indicate the impedence selection. In half-power mode, the minimum speaker
impedence is 8 ohms.
