ADJUSTING THE AMPLIFIER CONTROLS
STEP 1:
Plug your amplifier into a functional outlet and turn the power switch to ON. If applicable to your model, a status light will illuminate when the
amplifier is powered or a signal is detected, depending on the various settings selected.
STEP 2:
Set the power mode for the amplifier:
•
ON:
Places the amplifier in a continuous ON status. Power can be turned on/off using the power button on the front of the amplifier. Use this mode
for initial setup.
•
TRIGGER:
Turns the amplifier ON automatically upon receiving a 12 V signal. When the amplifier no longer receives a signal, it automatically turns
OFF.
•
AUTO:
Places the amplifier in an AUTO sensing status. When set to AUTO, the amplifier turns on automatically upon receiving an input signal.
When the amplifier no longer receives a signal, it automatically moves into a standby state after 15 minutes. Use this mode after the
adjustments are complete.
NOTE:
The NV-SUBAMP100 is always in auto-detect mode.
STEP 3:
Turn the EQ Mode to ON, then select an EQ preset, if desired.

STEP 4:
Place your adjustment controls into a neutral position.
•
VOLUME:
Set to 50% of full sound.
•
PHASE:
Set to 0°.
•
CROSSOVER:
If using the LFE input, set the control to LFE. If using line-level RCA cable connections, reference your subwoofer specifications and
set the amplifier to the low-end frequency limit of the subwoofer. A 60 Hz–80 Hz range is the typical setting for most applications.
STEP 5:
Turn on your sound system and play your favorite movie or music track.
STEP 6:
Adjust your controls as necessary to get the desired bass level.
•
VOLUME:
Increase or decrease the volume as desired.
•
PHASE:
Adjust the amount of bass heard from your subwoofer. When the bass is pleasing to you in your normal listening position, you have the
phase set correctly.
•
CROSSOVER:
When using LFE, you should not need to adjust the crossover knob after setting it to the low-level frequency limit of the subwoofer
used in your system. If the subwoofer is easy to locate by sound alone, lower the crossover frequency until the sound blends with the
system.
