Classe Audio CP-500 - V2.4 Owner's Manual page 15

4 Balanced (XLR) inputs
These XLR jacks accept right-channel and left-channel balanced signals from
source equipment with balanced outputs. Either of these inputs may be selected
by touching the corresponding button on the main operational screen of the LCD
touchscreen.
The pin assignments of the XLR-type female input connectors are:
Pin 1: Signal ground
Pin 2: Signal + (non-inverting)
Pin 3: Signal – (inverting)
Connector ground lug: chassis ground
Refer to the operating manuals of your balanced-output line-level sources to verify
that the pin assignments of their output connectors correspond to the CP-500. If
not, wire the cables so that the appropriate output pin connects to the equivalent
input pin.
To achieve the best possible results, we suggest that you use only high-quality
interconnect cables. Please consult with your local Classé dealer for advice on the
best cables for use in your system.
5 Tape output
Connect these RCA jacks to the right-channel and left-channel recording inputs of
your recorder.
These single-ended RCA outputs are unaffected by the volume control on the
front panel, or by whether you choose to monitor the source or the recorder
(by having the "tape" button on the front panel's touchscreen deselected or selected,
respectively). The record outputs will be disconnected when the preamplifier is
placed into standby, however.
6 Single-ended (RCA) main outputs
Single-ended cables using RCA connectors are the most common form of analog
connection used in consumer electronics. When implemented carefully and
used with high quality interconnect cables, this standard can provide excellent
performance.
Classé has gone to extraordinary effort to ensure that the single-ended
(RCA) outputs of your preamplifier are as good as possible. However, this
connection standard cannot offer the immunity from interference that balanced
interconnection does–hence our recommendation to use the balanced outputs
whenever possible.
If you are not using balanced analog interconnection, then connect these single-
ended outputs to your preamplifier/processor using high-quality shielded RCA-
terminated cables. Your Classé dealer can advise you on the selection of cables
suitable for your system.
