UNPACKING AND POSITIONING
Unpack your CAV-180 Multichannel Power
Amplifier carefully. If you notice any shipping
damage, contact your dealer immediately. Saving
the packaging material is advised in case the unit
needs to be shipped for service. If you choose to
dispose of the packaging, please recycle.

Positioning the CAV-180 Multichannel
Power Amplifier
For best performance, place your CAV-180
Multichannel Power Amplifier on a solid, non-
resonant surface. Do not place the CAV-180
Multichannel Power Amplifier directly on top
of another component.

Place the CAV-180 Power Amplifer near its final set-
up position, allowing 8 inches of clearance at the
rear for tightening the speaker output connectors.
For optimum sonic performance we recommend a
Classé Reference AC cord.
Please contact your dealer for more information.

The power transformer in the CAV-180
Multichannel Power Amplifier is located at the
bottom of the chassis and just behind the front
plate. Ideally a few feet should separate this area
from any components which are susceptible to
hum. These include preamplifers, turntables, and
interconnect cables. Allow 6 inches above and on
each side of the unit to provide adequate cooling.

CONNECTIONS
AC power
Check that the AC voltage for which this unit is
configured matches your local AC line voltage.
The correct operating voltage is indicated on the
rear of the chassis, adjacent to the AC power inlet.
Operating this unit on AC voltage other than that
specified on the rear of the unit can damage or
destroy this unit and increase the risk of electric
shock.

Connect the AC power cord to the rear of the
unit – See Fig 1 – and directly to an AC outlet.
For best results, do not use extension cords or
multiple-outlet “power strips”. Also, do not
disable the ground pin as this can increase the
risk of electric shock.

Analog inputs
The CAV-180 Multichannel Power Amplifier
has both balanced (XLR) and single-ended
(RCA) inputs – See Fig 1. Both types of inputs
have been carefully optimized to give best possible
performance. However, the most realistic and
natural sonic quality is obtained by connecting the
balanced outputs to the balanced inputs on your
amplifier.

amplifier.
The balanced (XLR) and single-ended (RCA) inputs
may be used separately but not simultaneously.
Ensure that your new CAV-180 Multichannel Power
Amplifier is OFF before changing any connections.
When the amplifier is shipped from Classé there is a
jumper between pins 1 and 3 of the balanced (XLR)
inputs. To use your amplifier in single-ended mode
simply connect the single-ended interconnects from
the preamplifier to the RCA inputs of your CAV-180
Multichannel Power Amplifier. To use your amplifier
in balanced mode, remove the single-ended
interconnects if attached. Remove the jumper
between pins 1 and 3 of the balanced (XLR) input
and save them for later use. Connect the balanced
interconnects from the preamplifier to the XLR
inputs of your CAV-180 Multichannel Power

Infrared (IR) input and output
The CAV-180 Multichannel Power Amplifier is
equipped with 1/8“ mini-plug connectors that allow
the unit to directly receive and transmit remote IR
commands – See Fig 1. These connectors can be
used with equipment that receives IR commands
and converts them for transmission on copper wire.
This is especially useful for situations where the
CAV-180 Multichannel Power Amplifier is outside of
the line-of-sight of your listening location. Contact
your Classé dealer for information on installing and
using remote IR repeating equipment.
