7 .1 - Audio Troubleshooting Tips
No power - Is the detachable AC cord fully plugged in? Is the rear panel power switch on?
Controls don't work - check the Security Level. If set to Full Lockout, then Protea unit is "view only". Change security
settings in Util menu or software.
No sound - Check to see if the input or output is muted. Is the input or output Gain turned down? Check the selected
audio source(s) for each output, making sure there is signal applied to the designated input(s). If the crossover is used, make
sure the high pass filter (HPF) is set to a lower frequency than the low pass filter (LPF).
Clip light stays on - Is the input signal level too high? Check to see that the nominal input level is 0dBu, allowing
20dB of input headroom. Are input or output gain settings too high? Check to see if an EQ filter has too much boost.
Distorted sound but no Clip LED- Check individual EQ filters to see if there is excessive boost.
Muffled sound - If expecting full range audio on an output, make sure the crossover settings are not inadvertently set
so as to limit the pass band.
Excessive Noise - An input signal level or an input gain setting that is too low could require the loss to be made up for
at the output gain stage, producing more noise than a properly set up gain structure. Do not use the DSP processor section for
dramatic increases in level, but rather optimize the signal source for a nominal 0dBu output.
