Caution!
Turn the volume on your controller/preamplifier all the way
down before attempting to connect anything to your Proceed
HPA 2 Power Amplifier.
1
AC MAINS RECEPTACLE
Connect the AC power cord (included in the accessory pack) to the IEC-
standard AC receptacle on the rear panel of the amplifier, then to the AC
mains outlet.
Warning!
Your Proceed amplifier has been safety-tested and is
designed for operation with a three-conductor power cord.
Do not defeat the “third pin” or earth ground of the AC power
cord.

COMMUNICATION PORTS
These RJ-45 communications ports provide for sophisticated inter-compo-
nent communications within the context of a Proceed system, allowing the
multichannel controller to toggle the amplifier between
operate
and
standby
as needed, without forcing the user to turn the amplifier on sepa-
rately. Since this communication link provides two-way communication, it is
more reliable and preferred over simpler DC trigger hookups (although we
support DC triggers as well, since their use is so widespread).
