AMP A, AMP B, INTERCOM & CASCADE
The AMP A, AMP B INTERCOM and CASCADE buttons work
just like the MUTE buttons for the channels. These just
have on and off states, and offer the same type of tally
information. The examples are given below for AMP A, just
change the parameters numbers for AMP B "08" (30h 38h),
INTERCOM "09" (30h 39h) or CASCADE IN "10" (31h 30h).
It should be noted that AMP A and AMP B buttons do not
power the amplifiers on and off... these buttons are mute

AV-452 Serial Control Specification
controls feeding the amps. These amps do have a power
switch in the rear separate from the main power, and there
is no status information on that switch.
Also, the CASCADE functionality changes with dip switch
settings on the rear panel of the AV-452. (One mode mixes
the cascade input with the internal system, the other mode
replaces the internal signal with the cascade port.) See the
AV-452 Owner's Manual for more detailed information.
