Troubleshooting - Chapter 6 CHAPTER 6 TROUBLESHOOTING Troubleshooting Index If you are experience problems while operating the MicroVerb 4, please use the following table to locate possible causes and solutions before contacting Alesis customer service for assistance. Symptom The display does not light when the unit is powered on. Sound is distorted, Red "Clip" LEDs are lit Does not respond to MIDI program changes or modulation control. No audio is heard. Hum or noise from output. Unit does not respond to front panel controls. Cause No power. Solution Check that the power cable is plugged in properly. Input level is too high. MIDI channel is set to a different number than the controlling device. Bypass function is on with Mix turned 100% wet. Output level is too low. Ground loop. Unknown software conflict, cosmic rays, aliens, or static electricity. Turn down the Input Level control. Hold [BANK/MIDI] and turn the [VALUE] knob to adjust the MIDI channel. Turn the Mix control to the left or press the Bypass Footswitch. Turn the Output control to the right. Try plugging the unit into another power jack or different audio cables. Disconnect MIDI input. Power down and power up again. If this doesn't work, try reinitialization. Re-initializing To re-initialize the MicroVerb 4, hold down both [STORE] and [BANK/MIDI] while turning on the power. This will reset all User Programs and the MIDI channel to their default values, and will recall Preset 00. 7 Important: The Programs in the User bank are erased when re-initializing the unit this way. Be sure you have stored these Programs into some sort of data storage device via MIDI System Exclusive before performing a re-initialization (see Chapter 6).
