SETTING GAIN, ADJUSTING PHASE, LOW-
PASS FILTER, AND BASS BOOST
1. Start with GAIN control set to minimum,
and the crossover control rotated midway.
2. Choose music with substantial bass
content and turn the volume control on
your receiver to ¾ of its total output.
3. Adjust the GAIN control clockwise,
listening carefully to the bass output. If
you hear distortion, turn the GAIN control
counterclockwise to decrease the GAIN.
4. Switch the PHASE back and forth to
determine which setting provides the most
clean bass output.
5. Adjust the LOW-PASS FILTER control
until the BassPro Nano plays only low-
frequency information – you should not
hear elements such as vocals coming from
the woofer.
6. Adjust the BASS-BOOST control
clockwise or counterclockwise to suit your
taste.

TROUBLESHOOTING
No audio and POWER indicator is off
• No voltage at BATT+ and/or terminals, or bad or no
ground connection. Check voltages at amplifier terminals with
VOM.
No audio and indicator ashes every 4 seconds
• DC voltage on amplifier output. Amplifier may need service; see
enclosed warranty card for service information.
No audio and and indicators ash
• Voltage less than 9V on BATT+ connection. Check vehicle
charging system.
No audio and indicator is on
• Amplifier is overheated. Make sure amplifier cooling is not
blocked at mounting location. Or, there may be voltage greater
than 16V (or less than 8.5V) on connection. Check
vehicle charging system.
Amplier fuse keeps blowing
• The wiring is connected incorrectly or there is a short circuit.
Check wiring connections.
Distorted audio
• is not set properly. Check setting. Check wires for shorts
or grounds. Amplifier or source unit may be defective.
Music lacks dynamics or “punch.”
• If using speaker-level inputs, check connections for proper
polarity. Switch back and forth between 0° and 180°
and leave on setting with best sound.
Engine noise—whining or clicking—in system when the
engine is on
• Amplifier is picking up alternator noise. First, check ground
connection on the amplifier – a loose or improper ground is
one of the main causes for noise. Turn down . Move RCA
audio cables away from power wires. Installing an alternator
noise filter on power line between battery and alternator might
also be necessary.
