Troubleshooting
It is possible for a static discharge to temporarily disable the microprocessor
that allows the controls to function. If this should occur, depress the ‘Mute’
button, then turn off the preamp and unplug the preamp from the A.C.
receptacle for 60 seconds. Reconnect the A.C. plug and turn the preamp
back on, along with other components. The controls should resume normal
operation. If the problem persists, contact your dealer or Audio Research
Customer Service at 763-577-9700.
