includes a built-in muting circuit to prevent
noise when the power switch is turned on and

turns off.
CONNECTIONS
CAUTION:
• Do not plug the AC power cord into an AC power outlet until all connections have been completed.
• Check the left and right channels and be sure to interconnect them properly, L (left) to L, R (right) to R.
• Plug the AC power cord in securely. An insecure connection could cause noise.
• Note that clamping pin-plug cords and power cords together or running pin-plug cords near the power
transformer could result in humming or noise.
• Check the polarities of the speakers and amplifier and be sure to interconnect properly. Connect the red
terminal on the speaker to the "+" speaker terminal on the amplifier, the black terminal on the speaker to
the "–" speaker terminal on the amplifier.

(1) Connecting the line input connector (LINE IN)

* Connect this to the pre-out connector for the active subwoofer on the AV amplifier ("SUBWOOFER PREOUT",
"MONO OUT", etc.) using the included connection cord (3-meter RCA pin cord).
CAUTION:
• If this connector is connected to the pre-out connector for the surround center channel of a stereo amplifier
or AV surround amplifier, only the center channel's bass sound will be produced, so the overall bass sound
will be insufficient.
