e pin assignments of these XLR input connectors are:
Pin 1: Signal ground
Pin 2: Signal + (non-inverting)
Pin 3: Signal – (inverting)
Connector ground lug: chassis ground
ese pin assignments are consistent with the standard adopted by the
Audio Engineering Society (AES14-1992).
If you are using your Classé power amplifi er with a Classé preamplifi er,
you’re all set – just take standard balanced interconnect cables and plug
them in. en engage that input on the power amplifi er by confi guring it as
described in Initial Setup.
If you are using another brand of preamplifi er, please refer to the operating
manual of your balanced-output preamplifi er to verify that the pin
assignments of its output connectors correspond to your amplifi er. If not,
have your dealer wire the cables so that the appropriate output pin
connects to the equivalent input pin.
2 Single-Ended (RCA) Input
Single-ended cables using RCA connectors are the most common form of
analog connection used in consumer electronics. When implemented
carefully and with use of high quality interconnecting cables, this standard
can provide excellent performance. Classé has gone to extraordinary eff ort
to ensure that the single-ended (RCA) inputs of your power amplifi er are
as good as possible. However, this connection standard cannot off er the
immunity from interference that balanced interconnection does—hence
our recommendation to use the balanced inputs when possible.
If you elect to use the single-ended inputs of your Classé power amplifi er,
you need to engage them by confi guring the amplifi er as described in
Initial Setup.
3 Speaker Outputs
A pair of high quality fi ve-way binding posts is provided for each channel
of the amplifi er.
Although the binding posts on your Classé amplifi er will accept bare wire
connections, we strongly recommend the use of high quality spade or hook
lugs, crimped and soldered onto the ends of your speaker wires. Using high
quality connectors will ensure that your speaker connections do not
gradually deteriorate from fraying and oxidizing bare wires. It also helps
prevent accidental short-circuits from poorly-terminated connections.
