In Case of Difficulty
If you experience low volume, hum only when the DSP volume control is
high, or distortion:
Double check the wiring used to connect the DSP to the receiver's speaker
and headphones jacks. The wiring can be tested by turning the DSP "off".
When the DSP power switch is in the "off" position, the audio input jack is
connected directly to the DSP's speaker and headphones jacks. If the DSP is
properly connected and the wiring is good, the volume level and audio quality
should be exactly the same as when the speaker or headphones is plugged
directly into the receiver's speaker or headphones jacks.
If the DSP fails to process properly when using the Automatic Notch or
Noise Reduction, or if the DSP audio is distorted intermittently:
The receiver's volume or the DSP's level control may need to be adjusted.
Check the Input Level LED.
If you hear hum at high or low volume:
The power supply you are using may not be filtered properly.
If the DSP won't start or shuts off intermittently:
The power supply may not be within the required 10-16 volt range. If the
power supply drops below 10 volts from poor regulation or a bad connection,
the DSP may operate erratically An indication of poor power is the power LED
flashing from red and green.
