Thanks for purchasing this 350W Subwoofer Amplifier. The
amplifier is designed for home theater application. It features an
extension (or rumble) filter that can be used to correct the bass roll-
off of the subwoofer and/or to adjust for room response in the bass
band. In addition, the amplifier is packed with other standard
features such as both speaker level and line level inputs, high-pass
line outputs (12db/oct) for the satellite speakers, continuously
adjustable crossover frequency (40-160hz) for the subwoofer
output, automatic on/off switch (activated by input signal), and a
subwoofer volume control. Mated with a high quality subwoofer
driver, its
350W@4ohm
output is enough to shake your room.
Thermal protection and short circuit protection circuitry ensure
long-lasting durability.
Note: 1. The auto on is only available on left channel input.
2. This amp is intended to be used with a HT receiver, where phase control is not needed. For
musical applications, where phase control is important, we recommend the special edition
amps.
Technical specs
Crossover frequency control
Continuously variable for the subwoofer from 40hz to 160hz, 2
nd
order characteristic (12db/oct).
Phase control
Continuously adjustable phase lag control on the subwoofer from 0
to 180 degrees. Not recommended to use. Please use delay time
adjustment on the home-theater receiver to adjust the phase.
Power switch (Auto ON/OFF)
When the switch is in the auto position, the amplifier will turn on
when the left channel input signal is present. There are also ON and
OFF positions that can override this function.
Volume control
Adjust the output level of subwoofer.
Line in
These are line level RCA inputs. Use them to connect pre-outs or
preamplifier outputs. These inputs are summed as mono. It is the
preferred input method. Mono line level signals needs to connect left
channel input. See setup section for more explanation.
Line out
This line level RCA outputs is high-pass at 100hz (-3db) for satellite
output if the amplifier(s) driving the satellite has a line level direct
inputs.
High Level in
Speaker level input. Use these inputs when the line level outputs
from your receiver are not available. Connect these inputs directly
from the amp outs the drive satellite (or front) speakers.
