Make your preamp connections | Classe Audio CA-3200 guide

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), and 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.

.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.
