Subwoofer controls
➊
Power mode
"On" means that the subwoofer is operational
and permanently active. "Auto" means that the
subwoofer is operational but is only activated
once it receives an audio signal. In "Auto" mode,
the subwoofer automatically switches to standby
after 20 minutes of inactivity.
➋
Phase
This switch determines the phase relationship be-
tween the subwoofer and the front/centre speakers.
If you are using a modern AV receiver and/or the
subwoofer is positioned in the speaker set-up as
indicated on p. 7 (grey area of drawing), set the
phase to "0°". With other set-ups, the "180°" set-
ting may produce better results.
➌
Level
Use the "Level" control to adjust the subwoofer's
volume. In the receiver's bass management section,
set the bass level to a high value, i.e., b6
and +12 dB. Next, set the subwoofer's level control
to 10 o'clock. While the AV receiver is outputting its
white noise set-up signal, slowly turn up the subwoo-
fer level to the desired volume.
➍
Frequency
Use this control to set the crossover frequency bet-
ween the subwoofer's bass signal and the bass fre-
quencies of the other speakers. If you are using an
AV receiver, set the receiver's crossover frequency
to 150 Hz and turn the subwoofer's frequency con-
trol to maximum (hard right).
➎
Line input
Connect the AV receiver's "Sub Out" to the sub-
woofer's "Line input" using a mono RCA cable (op-
tionally with a Y adapter).
➏
High level
Use these speaker sockets to connect the sub-
woofer to a conventional stereo amplifier or a
surround receiver without a dedicated subwoofer
output. Do not connect anything here if you are
using a multi-channel AV receiver with a sub out.
➐
Power
Switch to "On" to power up the subwoofer; switch
to "Off" to power it down.
➑
Mains power socket
➒
Fuse
This is where the mains power fuse is located.
When replacing the fuse, make sure the new fuse
has the same rating.
