4.0 Troubleshooting
CONDITION: No power to the mixer-amplifier so that
the power ring is not illuminated.
POSSIBLE REASON: The mixer-amplifier is not plugged into the power receptacle
CONDITION: No sound or low sound.
POSSIBLE REASON: The input signal is not present or at a very low level.
POSSIBLE REASON: The Master Volume control is turned down.
POSSIBLE REASON: A CSR-V is connected and turned down.
POSSIBLE REASON: Mixer channel inputs are turned down.
POSSIBLE REASON: The Ch 1 Priority switch is closed, muting all except Ch 1 input.
POSSIBLE REASON: The Hi-Z switch is OFF while using the 70V or 100V outputs.
POSSIBLE REASON: The power switch is OFF. (Note that while plugged in, the
amplifier will be in standby mode and the power ring will be
green until the power switch is activated
and the power ring will turn blue.)
CONDITION: Distorted sound.
POSSIBLE REASON: Input signal level is too high. Please turn down the input level
controls. Note that the mixer-amplifier should not be operated
at a level that allows the clip indicator (red ring around the
Master Volume) to be constantly ON.
POSSIBLE REASON: Master Volume is too high.
POSSIBLE REASON: MIC/LINE switch is in MIC position when using a
line level source.
