Caution
1. This subwoofer has electronics built into the cabinet and must be properly
ventilated.
2. Do not place the rear of cabinet against a wall, you must allow room for
adequate ventilation of the amplifier (at least 2 inches).
3. Do not place the subwoofer next to heat sources, such as furnace registers,
radiators, etc.
4. Do not place the subwoofer near sources of excessive moisture, such as
evaporative coolers, humidifiers, etc.
5. The power cord should be routed in such a way that it will not be walked
on, pinched, cut, or compressed in any way that could result in damaging the
insulation or wire. Damage to the power cord may result in a shock or fire
hazard.
Connections
All connections for the subwoofer are located on the rear of the unit. Whether you
choose the LFE (Low Frequency Effects) coaxial, Left & Right coaxial or XLR-input,
the subwoofer is auto selecting the one input where there is signal.
Home theater
system
Utilizing this method, the receiver or processor is the main control center for the
system and it provides all the bass management (e.g. sending the low frequency
signals from the satellite speaker channels & LFE for movies, to the subwoofer),
and it provides a low-pass filtered signal (bass information only) to the subwoofer.
Most home theater receivers/processors have at least 1 unbalanced RCA
“SUBWOOFER” output jack, some models have two. For this type of equipment,
connect a single high quality cable from your receiver’s “SUBWOOFER” output
jack to the subwoofer’s input marked with as “LFE”
If your receiver or processor has multiple subwoofer outputs, you may have additional
connection options. Consult the owner’s manual for your receiver/processor to verify
if these outputs are all the same.
Receiver/pre-amp
with internal
crossover
- By connecting to “LFE” input, the internal crossover filter is now by-passed
- The frequency control knob has no effect when using the “LFE” input.
- Adjust the “VOLUME” control knob to poiningt upwards, 12 o’clock.
- Set the “PHASE” to “0”
Music system
Utilizing this method, the preamp provides a full range signal from both left & right
audio channels to the subwoofer. If your preamp does not offer an internal crossover
or bass management functions, the subwoofer’s built in controls will need to be
properly set to utilize the built in crossover and phase adjustments to blend the
subwoofer output with the satellite speakers.
This subwoofer is designed to operate from either a full range audio signal (when
using the subwoofer’s built-in crossover) or home theater (surround sound)
processor/receiver with a “SUBWOOFER” output jack and built in low-pass filter &
bass management. In both cases, proper control settings are required to achieve
optimal system performance.
Amplifier/pre-amp
without
internal crossover
-
By connecting to high level speaker cable inputs or RCA L & R inputs the
internal crossover is used
-
Adjust the “FREQUENCY” control knob to blend the subwoofer output seam-
lessly with your main speakers.
-
Adjust the “VOLUME” control knob to match the output level of the subwoofer
toyour main speakers
-
Adjust the “PHASE” switch to smoothly blend the mid-bass output of the
subwoofer to your main speakers (read Calibration section for further informa-
tion).
