Abstract:
An apparatus for patching an outboard accessory device into a signal path of a multi-channel amplifier, the apparatus comprising:a plurality of variable attenuators each coupled to a particular channel in the multi-channel amplifier for controlling a channel signal amplitude; a common effect-send terminal alternately coupled to one of the plurality of variable attenuators for receiving an output signal from the multi-channel amplifier, the common effect-send terminal optionally coupled to an input of an outboard accessory device; a common effect-receive terminal optionally coupled to an output of the outboard accessory device for receiving an outboard output signal; an effect-mix variable device which is electrically coupled in parallel with the common effect send and receive terminals and which is controllable by a user to combine a first user-selectable amount of signal directly from the common effect send terminal with a second user-selectable amount of signal directly from the common effect receive terminal to form a mixed signal; and a variably controllable amplifier means coupled to the effect-mix variable device for receiving the mixed signal and delivering an amplified output signal to an output terminal.
