RCA Input
L & R
RCA inputs for left and right channel. The left and right inputs are summed up, providing bass for both channels.
These inputs use the low pass filter function.
RCA Input
LFE
The LFE bypasses the low pass filter. When using a receiver with internal filters,
LFE should be used instead of Left & Right to not interfere with the settings in the receiver.
High Level Input
With the high level input you have the ability use the subwoofer with amplifiers that lack a “SUB OUT” or “PRE
OUT” functions. Simply connect a duplicate of left and right speaker cable to the instructed connections on
the subwoofers back, marked with “HIGH LEVEL IN”.
VOLUME
(set to pointing upwards/12
o’clock if using a surround
processor)
This control allows you to adjust the output level of the subwoofer to match the main speakers in your system.
For most home theater receivers & surround sound processors, set the volume control to pointing upwards
/ 12 o’clock position. For music systems, start with the volume control at a low setting and increase slowly
until the levels match. The use of test tones (from a receiver/processor’s built in calibration function or test
disc) and SPL meter are suggested for proper level matching of all speakers.
CROSSOVER
40 to 160 Hz
This control allows you to adjust the upper limit of the subwoofer’s frequency response from 40 to 160 Hz.
The subwoofer’s output level will be reduced above the frequency this control is set to. You should set the
crossover frequency to obtain a smooth and seamless transition from the subwoofer to the main speakers
in your system. If your main speakers are smaller units with limited low frequency output, start with a higher
frequency (such as 100-150 Hz). With larger speakers that have greater low frequency output, you might
start with this control set lower (such as 60-100 Hz).
PHASE
0° - 180°
(set to 0° if
using a surround processor)
The phase control can adjust the sound from the subwoofer to match your loudspeakers with the conditions
within the actual room. Choose the control setting which gives the best possible sound reproduction. If your
amplifier is able to execute the bass management, you should choose 0° and then start the measurement
system of your amplifier.
Power LED
LED Colour Function
GREEN ON The unit is turned on and working normal
RED STANDBY Waiting for signal to power on
EQ Setting Switch
This switch allows you to choose between the three different EQ settings. REF, EQ1 & EQ 2 are explained
in the “EQ Settings” section, found on page 12.
Power Mode
ALWAYS ON/AUTO
The Power Mode switch can be used to select from two operating modes. In the “AUTO” position, the subwoofer
automatically switches itself on when a signal is detected. In the absence of any signal for a certain time
your subwoofer automatically returns to Standby Mode. If the Amplifier Mode switch is “ALWAYS ON”, the
subwoofer will always stay switched on.
AC Power Switch
(110 or 220V)
Make sure the “AC Power Switch” is set to the correct voltage before you insert the power cord. Wrong setting
can destroy the amplifier and will not be covered by the warranty.
Main Power Switch
To switch on the subwoofer, flick the switch to the “ON” position. To cut the power, flick the switch to the
“OFF” position.
