Installation - Classe Audio Sigma Series Owner's Manual

Installation

Your new Classé amplifier is quite simple to set up and enjoy. Please follow the
steps outlined below in order to safely set up and use your new amplifier.
Important: The AC mains connection should be the last connection you
make on your new power amplifier. In addition, it is always
a good idea to power up your power amplifier(s) last, after
everything else has been powered up and has stabilized.
Conversely, it is good practice to power the amplifier(s)
down first when shutting down the system, as this
prevents any transients from other components from
getting through to your loudspeakers.
1. Unpack everything according to the included instructions.
Be careful when doing so, as this amplifier is heavier than it appears.
2. Place your amplifier (be sure to read "Unpacking and Placement")
and connect it to the AC mains. This includes deciding on the location,
making sure you have adequate ventilation, and adequate clearance for all the
wires behind the amplifier. Once accomplished, connect the amplifier directly to
the AC mains. Do not use extension cords, as most are not suitable for the current
sometimes required by your amplifier.
3. Configure your amplifier turn-on delay/amp number.
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).
The amplifier sequence number (turn-on delay) may be programmed by
your Classé dealer using a PC utility.
4. Make your preamp/processor 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.
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.
