SUBWOOFER AMPLIFIER CONTROLS & SETUP
This section describes the functions and/or use for each of the amplifier controls located on the back
of the subwoofer. Refer to the diagrams on the pages 8 and 9.
1. Voltage Selector Switch:
Before connecting the amplifier to any power source make sure the AC Voltage Selector is
set to either 110V or 220V to match the power voltage in your area.
NOTE: If switching voltage, also make sure to change the fuse (see #8).
WARNING! If the voltage setting does not match the AC power supplied, damage to the
Subwoofer Amplifier may result.
2. Volume/Gain Control:
The volume/level control should be at the minimum setting (all the way counter-clockwise)
before plugging the subwoofer into an AC wall socket. Once plugged in, turn the level
control up one quarter of a turn (9 o’clock position) for an initial setting. The level control
may be adjusted while playing to match the subwoofer level with the rest of the system.
IMPORTANT! The volume control should be at the minimum setting (all the way counter-
clockwise) before plugging the subwoofer into an AC wall socket.
IMPORTANT NOTICE REGARDING BASS MANAGEMENT
It is important the signal being sent to the subwoofer be a non-boosted
or “flat” signal. Every 3dB of boost relate to doubling the output from the
amplifier and may eventually overload the amplifier and speaker. Check
the settings on your receiver or processor to make sure any “bass boost”,
“super-bass” or “loudness” is set to Off. In most cases a home theater
receiver or processor will determine the crossover frequency through
bass management settings. In this configuration, connect the receiver or
processor to the LFE (Low Frequency Effect) output. Your subwoofer will
now reproduce the bass frequencies as they were originally recorded. Use
the subwoofer level control and the individual bass management control
within the receiver or processor to adjust the subwoofers’ volume. Once
set, the volume controls should not need to be altered as the subwoofers’
volume will track with the master volume control of your receiver or
processor. Use Line Input only if bypassing your preamp or receivers
internal processing to deliver a full signal to your subwoofer which is then
managed by the subwoofer’s frequency and volume control.
