Status indicator
The two-colored LED indicates the active
subwoofers operating status, as follows:
Power ON...............................Lights green
Auto power off (standby mode) .....Lights red
Power OFF .....................................LED off
Protective circuit activated..........Flashing red
o
Power switch (POWER)
The power turns on when this switch is set to
the ON position.
Several seconds are required for the set to
begin operating. This is because the set
includes a built-in muting circuit to prevent
noise when the power switch is turned on and
off.
When set to the OFF position, the power
turns off.
Auto Standby Function
The amplifier is automatically set to the standby
mode if no signal is input for 5 to 11 minutes,
thereby saving electricity.
The power turns on immediately when a signal
is input.
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.
CONNECTIONS
(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 channels bass sound will be produced, so the overall bass sound
will be insufficient.
Active subwoofer (DSW-3L)
Included connection cord
(3-meter RCA pin cord)
