Other Cautions (SC-A3L, SC-C3L)
2 Note that color blotching may occur on a TV, etc., due to interaction with the speaker system if there is a
magnet or an object generating magnetic force nearby.
Examples: (a) When there are magnets on the door of the rack, stand, etc.
(b) When a health device, etc., equipped with magnets is placed nearby.
(c) When toys or other objects using magnets are placed nearby.
2 Note that the illustrations in this instructions may differ from the actual set for explanation purposes.
2 Be sure to keep the operating instructions.
After reading these operating instructions, store them in a safe place. We also recommend filling in the
necessary items on the back cover.
Cautions on Installation – Active subwoofer (DSW-3L)
2 Note that placing the active subwoofer on the same stand or shelf as a record player may result in howling.
2 The DSW-3L active subwoofer is a Lowleakage-Flux type speaker system and can be used near televisions,
but depending on the TV there may be color blotching on the picture. If this happens, turn off the TV's power,
move the TV and subwoofer a little apart, wait 15 to 30 minutes, then turn the TV's power back on. The TV's
automatic degaussing circuit should reduce the blotching on the picture. If blotching persists, move the
subwoofer and TV further away from each other.
2 Install on a firm, flat floor to prevent accidents due to toppling down.
2 Do not place a record player, CD player or other AV device on top of the subwoofer.
Other Cautions – Active subwoofer (DSW-3L)
2 The built-in amplifier of the active subwoofer (DSW-3L) includes a muting circuit. The output signal is strongly
attenuated for several seconds after the power is turned on. If the volume is adjusted during this time, the
output may be extremely high when the muting circuit is deactivated. Be sure to wait for the muting circuit
to be deactivated before adjusting the volume.
2 Note that color blotching may occur on a TV, etc., due to interaction with the subwoofer if there is a magnet
or an object generating magnetic force nearby.
Examples: (a) When there are magnets on the door of the rack, stand, etc.
(b) When a health device, etc., equipped with magnets is placed nearby.
(c) When toys or other objects using magnets are placed nearby.

WARNING:
• Be sure to fasten the power cord to a wall, etc., to prevent people from tripping over it or otherwise pulling
on it accidentally, causing the subwoofer to fall.

q
Line input connector (LINE IN)
• Connect this to the AV amplifier's pre-out
connector ("SUBWOOFER", "MONO OUT",
etc.) using the included connection cord (3-
meter RCA pin cord).
w
Line output connector (LINE OUT)
• The signal input to the line input connector is
output as such from here in parallel.
• When using two active subwoofers, connect
the other active subwoofer's line input
connector to this connector.
e
Phase selector switch (PHASE)
• This switches the phase of the output signal
with respect to the input signal.
• Normally use the subwoofer with this switch
set at the "NORM." position. If the continuity
between the sound of the active subwoofer
and the left and right speakers seems
unnatural, try switching to the "REV."
position, and set the switch to the position in
which the sound is most natural.

LF direct switch (LF DIRECT)
• When using the active subwoofer connected
to a Dolby Digital- or dts-compatible AV
amplifier, if this function is turned on the
signals bypass the active subwoofer's
crossover and volume adjustment circuits,
resulting in purer, higher quality sound. Note
that when this is done the crossover

adjustment control
adjustment control ( y ) will no longer function.
When using in combination with the AVR-550SD,
we recommend turning the LF DIRECT switch on
and setting the AVR-550SD's crossover frequency
to 150 Hz.
