After completing the installation, follow these steps to set the Gain Control and then perform
the Final System Checks.
1.
Turn the Gain Control all the way counter-clockwise.
2.
Turn the vessel's Ignition Switch to the ON position. Then turn the ON/OFF Switch on
the source units to the ON position. Set all Tone or Equalization Controls to "flat" positions
and turn Loudness off.
3.
Play a CD or Tape and set the Volume Control at 75% of full level. NOTE: If the system
uses an equalizer, set its frequency controls to "flat" positions.
4.
Slowly increase the Gain Control. Stop when you hear a slight distortion of audio.
The Audiopipe AP2002 features a fully adjustable crossover. To set the crossover, follow
these steps.
1.
Using the X-Over Mode Switch, select the desired mode - LP for Low Pass, HP for High
Pass and OFF for Full Range.
2.
Using the Freq (Hz) Control, select the desired frequency. If the desired frequency
exceeds the range of the Freq (Hz) Control, press the Crossover Frequency Multiplier
Switch to increase the value by a multiplier of 10.
• For example, 55Hz x 10 = 550Hz or 550Hz x 10 = 5.5kHz.
1.
Initially set the Bass Boost control to its full left position (i.e. 0dB).
2.
Listen to a variety of music styles (e.g. Rock, Rap, etc.) and slowly increase the Bass
Boost control until a noticeable increase in low bass response is perceived.
3.
Slowly adjust the Bass Boost control (up or down) to realize the best bass response.
CAUTION: If you hear a "pop" (due to speaker over-excursion), lower the Bass Boost to
prevent speaker damage. If the system sounds muddy and distorted (due to marine
amplifier clipping), lower Bass Boost to avoid shutdown from overheating.
1.
Start the engine and turn on the source unit. After a two-second delay, slowly increase
the Volume Control and listen to the audio. If you hear any noise, static, distortion or
no sound at all, check the connections, and also refer to Troubleshooting. Depending
on your system design, the levels may become quite loud even at low Volume Control
settings. Until you get an "audio feel" of the system's power, use care when adjusting
controls.
2.
Turn the Balance Controls to their extreme positions and listen to the results. Audio
imaging should match control settings (audio from the left speaker when balance is left).
3.
Increase the volume and verify that the marine amplifier reproduces audio (at full
frequencies) without distortion. If you hear distortion, check the connections and verify
that the Gain Control is set correctly. Another possibility is damaged speakers or under-
powered speakers. Once again refer to Troubleshooting for additional help.
