Power switch
(ON, OFF)
Power switch. Press down "I" to power on and the indicator will
be lighted. Press "0" to power off. Make sure it is set OFF when
connecting / disconnecting cables.
There is an automatic switch on the subwoofer. When it has
signal in, it will switch on and consequently switch to standby
(this is indicated by the LED, which turns blue when standby is
present) when no signal is present (after a certain time period).
Therefore, you can have it ON constantly.
To obtain the optimal sound, you should let
the subwoofer be in ON mode. The amplifier
will then immediately have the right working
temperature from the beginning.
Turn off the subwoofer if it is not in use for a
long period.
VOLUME
Controls volume level of subwoofer.
Be gentle on the volume
knob,
please remember that certain sound signals may contain
a lot of energy.
FREQUENCY
Variable control from 50Hz to 135Hz provides(-3dB) optimum
setting of subwoofer crossover frequency to match crossover
frequency of Home Theatre components.
EQ
When EQ switch is ON, it will increase about 7dB at 50Hz.
When switch is OFF, it will not increase.
It is NOT RECOMMENDED to use this switch
in normal cases. The risk of damage is
increased. However, if the sensibility is low it
may be used.
PHASE
0-180 phase adjustment
HIGH PASS
Switch ON and the high pass is available. Switch OFF and the
high pass is unavailable.
The high pass crossover removes the deepest
part of the bass spectra. This is helpful in
many rooms, since they heavily amplifies the
deep bass tones, which may lead to
uncontrolled bass.
BALANCE
Balanced input
LINE IN
Line-level inputs to subwoofer. Use these RCA jacks to connect
audio
signals from line-level outputs on a receiver, preamplifier,
television set or surround sound decoder. If only a mono
(single) subwoofer output is provided, connect it to either of
input jack.
Remark: By connecting both line in inputs to
the same signal, you increase the level by 3 dB.
Certain types of simplier low level audio cables
may create a noise in the subwoofer. We
recommend double shielded low level cables
to be used.
SPEAKER IN
Stereo high-level inputs to subwoofer. Use these terminals when
line-level connections are not available from receiver,
preamplifier or surround sound decoder.
AC INPUT
Connect to regular 230 V / 50 Hz.
