Make sure you configure the amplifier to use the type of input
connection you will be using.
In a system that contains multiple Classé amplifiers, you may desig-
nate the amplifiers as #1, #2, #3 and so on. When the amplifiers
are linked to a Classé preamplifier via the CAN Bus communica-
tions or Trigger systems, they will turn on in the order you speci-
fied, rather than all at once. (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.)
To designate a particular amplifier as #x, for example:
• Place the amplifier in standby (Standby LED on)
• Press and hold the mode button until all the channel
LEDs are lit. When you let go, all the LEDs will blink to
indicate the current "number" of the amplifier (e.g., twice
to indicate amplifier #2).
• If you want to change the current amplifier number set-
ting, press and hold the mode button again until the chan-
nel LEDs are on.
• While continuing to hold the mode button, click the se-
lect button "x" times (the same number as the desired am-
plifier number);
• Release the mode button. The amplifier will confirm your
choice by blinking the channel LEDs "x" times.
4 Make your preamp connections.
With the amplifier in standby or disconnected from the AC mains,
and using the appropriate balanced or single-ended connections as
chosen in Step 3, make the appropriate connections using high
quality interconnecting cables.
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 ampli-
fier 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 ampli-
fier to the red (+) terminals on your speaker. If biwiring, run a to-
tal of four conductors between each amplifier channel and its cor-
responding 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.
