6.4 Final System Checks
1. Turn on the power to your audio system and ensure the stereo source unit is also powered
on.
2. The amplifier’s status LED will turn red during ‘start up’ and after a few seconds will then
turn blue to indicate the amplifier is operational.
3. Once the LED illuminates blue, wait at least two seconds then slowly increase the volume
control and listen to the audio. If you hear any noise, static, distortion or no sound at all,
check all the connections and refer to Troubleshooting. Depending on your system, the
volume may become quite loud even at low level settings. Use care when adjusting the
controls.
4. Turn the source unit’s balance controls to extreme positions (left and right) and listen to
the results. Audio output from the speakers should match the source unit settings (i.e. audio
from left speaker when balance is left).
5. Increase the volume and ensure the amplifier produces the audio at full frequencies and
without distortion. If you hear any distortion check the connections and verify that the gain
control is set correctly and/or Refer to troubleshooting.
If the LED remains red this indicates the amplifier is in Protect mode. Turn the amplifier off, check all wiring and
turn on again. If LED continues to stay red, contact your local Aquatic AV dealer.
