FINE TUNE
After making all connections and calibrating the speakers, fine tune the subwoofer as instructed below.
NOTE:
When using an AV receiver and the LFE input, set the subwoofer calibration level to the factory setting.
1. Ensure that the subwoofer is plugged in.
During initial setup, set the ‘POWER MODES’ switch to the ‘ON’ position. Once calibration is complete, switch to
‘AUTO’ to enable the automatic power-saving mode. For reference, the different modes are as follows:
TRIGGER:
Amplifier turns on when 12V signal is detected and off when 12V signal is absent.
AUTO:
Auto sense enabled. Amplifier turns on when audio signal is detected. Unit enters standby mode if no
signal is sensed after 15 minutes.
ON:
Always on. Amplifier does not turn off automatically. Unit turns on/off using the front panel power button.
2. If using one of the EQ presets, switch the ‘EQ MODE’ to the ‘ON’ position. Then select the desired setting.
EQ PRESET A:
+4dB (optimized for enclosures > 4 cu. ft.)
EQ PRESET B:
+7dB (optimized for enclosures 1 to 4 cu. ft.)
EQ PRESET C:
+10dB (optimized for enclosures < 1 cu. ft.)
3. Set the controls to positions that will enable tuning for maximum performance.
VOLUME
set to 50%, or 12 o’clock
CROSSOVER
set to 175 Hz, or 12 o’clock – OR – set to ‘LFE’ if LFE input is used
PHASE
set to 0º
4. Play a movie scene or music track and set the system volume to an average level. Listen to the bass level from
the preferred listening position. Adjust the ‘VOLUME’ control as desired.
5. If deeper bass is desired, adjust the ‘CROSSOVER’ control toward the lower frequencies. Experiment with
different frequency settings until finding one that sounds best.
NOTE:
When using the LFE input, set to LFE and make any crossover adjustments in the preamplifier or receiver
crossover settings.
6. Continue listening to music and movie sources using the settings chosen for volume and crossover.
7. Experiment with the phase until finding the best setting. Depending on the subwoofer’s placement, the bass
may sound louder or deeper when the phase has been optimized. In some cases, adjusting phase will make
no discernible difference.
