Check input signal and connection leads
Ensure input level and frequency controls are not turned fully down
Humming noise without any signal present
Test the GND/LIFT switch and check if the noise is from mains earth
Check integrity of signal leads and ensure they are well screened
Output very distorted and/or power LED is
frequently red
Turn down the input level rotary or output level from the audio source
Adjust the cutoff to a lower frequency
Output is working but at very low level
Ensure input source is at line level
Test the phase switch and check if one setting is louder than the other
Increase input level control or output level from audio source
