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
