IMPORTANT: Make sure all equipment is turned off before making
any connections.
For speaker connections, use a minimum #16-gauge 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 of
speaker wire is required. The wire channels on the rear of the
Infinity Alpha 25
ES
will accommodate most types of 14- to 18-
gauge wire.
NOTE:
If desired, consult your local Infinity 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 8.
To ensure proper polarity, connect each
+
terminal on the back
of the amplifier or receiver to the respective
+
(red) terminal on
each speaker, as shown in Figure 9. Connect the
–
(black)
terminals in a similar way. See the owner’s guides that were
included with your amplifier or receiver to confirm 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
.
NOTE:
Banana plugs will protrude past the speaker enclosure,
requiring a small cutout in the wall behind the speaker. Speaker
wire may be run through this hole as well.
