IMPORTANT: Make sure all equipment is turned off before
making any connections
.
For speaker connections, use a high-quality speaker wire with
polarity coding.The side of the wire with a ridge or other coding
is usually considered positive polarity (i.e., +). Heavier-gauge
wire should be used when more than 50 feet (15m) of speaker
wire is required.The wire channels on the rear of the C255ES
will accommodate most types of 14- to 18-gauge wire.
NOTE:
If desired, consult your local Infi nity dealer about speaker
wire and connection options.
The speakers have coded terminals that accept a variety of wire-
connectors.The most common connection is shown in Figure 7.
To ensure proper polarity, connect each + terminal on the back
of the amplifi er or receiver to the resp (red) terminal on
each speaker, as shown in Figure 8. Connect the – (black) termi-
nals in a similar way. See the owner’s guides that were included
with your amplifi er or receiver to confi rm connection procedures.
IMPORTANT: Do not reverse polarities (i.e., + to – or – to +)
when making connections. Doing so will cause poor imaging and
diminished bass response.
Figure 7. This example shows how to connect bare wires to the
terminals.
