Setting Up
Connect the speakers
CAUTION: Before making any connections, turn off your receiver
or amplifier and unplug it from the AC power (mains) outlet. Not
doing so may result in damage to your system.
CAUTION: Never use broken or frayed wiring, which can result in
damage to your components.
Note: Before running speaker cord through a wall or under a floor,
check your local building code requirements and safety regula-
tions. You may want to contact an electrical installer for this infor-
mation.
If your receiver’s center channel is not amplified, you must con-
nect an amplifier to the receiver. Use an RCA cable to connect the
center channel RCA-type output on the receiver to the RCA-type
input on the amplifier. The speaker will then connect directly to the
amplifier instead of to the receiver.
Choosing speaker cord
Be sure to use the proper gauge (thickness) of speaker cord.
Standard zip cord (2-conductor, 18-gauge wire found at electrical
and hardware stores) works for most applications. If your speak
-
ers will be more than 30 feet (9 m) from the receiver or amplifier,
see the following table, or check with your authorized Bose dealer.
* Based on a maximum frequency response deviation of ±0.5dB.
At the ends of each cord, strip approximately 1⁄2 inch (12 mm) of
insulation from both wires. Twist the bare end of each wire, so
loose strands will not touch across terminals.
Be sure to use the cord properly
Speaker cord consists of two insulated wires. The insulation
around one wire is marked (striped, collared, or ribbed). This
marked wire is always positive (+). The plain wire is always nega
-
tive (–). These wires correspond to the red (+) and black (–) termi-
nals on the speaker and the receiver or amplifier.
Note: It is sometimes difficult to distinguish wire markings. Inspect
both wires carefully.
