Appeal No. 1998-2612 Application 08/478,289 The disclosed invention pertains to an apparatus for patching an outboard accessory device into a signal path of a multi-channel music amplifier. More particularly, an effect-mix variable device is coupled between send and receive terminals which are optionally coupled to the outboard accessory device. The effect-mix variable device is controllable by a user to combine affected signal received from the outboard accessory device with unaffected signal received from the send terminal. Representative claim 13 is reproduced as follows: 13. 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 -2-Page: Previous 1 2 3 4 5 6 7 8 9 10 NextLast modified: November 3, 2007
