configuring amplifier
turn-on delay/amp no.
In a system that contains multiple Classé amplifiers, you may set the
number of seconds of turn-on delay for each amplifier, allowing each
to turn on in the order you have specified, rather than all at once.
This
number also acts as an ID when using the CAN Bus. (Having several powerful
amplifiers all turning on at the same time can sometimes stress the AC mains in
your home, potentially leading to nuisance tripping of circuit breakers).
For example, to set the delay for two seconds (and to designate a particular
amplifier as #2):
Place the amplifier in standby
(Standby LED on)
Press and hold the Mode
button until both Channel LEDs are
lit. When released, both LEDs will blink to indicate the turn-on
delay and current number of the amplifier (e.g. once to indicate a
one second delay and amplifier #1).
If you want to change the current amplifier number setting, press
and hold the Mode button again until both Channel LEDs are
on.
While continuing to hold the Mode button, press the Select
button two times (the same number as the desired delay in
seconds and the amplifier number);
Release the Mode button. The amplifier will confirm your choice
by blinking the Channel LEDs twice.
4. Make your preamp connections.
With the amplifier in standby (or disconnected from the AC mains), using
high quality interconnecting cables, make the appropriate connections
with the balanced or single-ended connectors (as configured in Step 3
).
Make sure all the connections are snug, even if it means gently squeezing
the outer shell of the RCA with pliers and reinserting it to tighten the
connection.
5. Make your speaker connections.
Make the connection between the output terminals of the amplifier and
your loudspeakers, using high quality speaker wires.
Connect the black (–) terminals on the amplifier to the black (–) terminals
on your speaker, and the red (+) terminals on the amplifier to the red (+)
terminals on your speaker. If bi-wiring, run a total of four conductors
between each amplifier channel and its corresponding loudspeaker: two
separate +/– leads, one for the bass and the other for the mids and treble.
Make sure that no wires cross between the red (+) and black (–) terminals,
at either end.
Make sure all the connections are snug and cannot be easily wiggled free,
but do not overtighten them. If you can give the speaker wires a reasonable
tug without movement, they are snug. Further tightening will not make a
better connection, and (taken to the extreme) may damage the connectors.
