Meters Present, No Audio Reproduced
The most obvious reason for this would be that the unit is muted, as indicated by a “re-
verse-video M” in the top right corner of the display. If the unit is not muted, ensure that
the volume control is turned up to a nominal level (such as -20dB). If the unit is not muted
and is set to a sufficient volume, check to make sure that the bar graph meters that are
showing signal presence have channels indicated below them. This determines which
channels are routed to the monitoring system for reproduction over speakers, headphones,
or analog outputs. If active bar graphs have no channels indicated, press the Up and Down
sections of the Menu ring to cycle through the programs.
It is possible to invoke the protection circuitry in the power amplifiers. As we have found,
this can be quickly accomplished by leaving the volume control set to +10 and applying a
full-scale signal. While it might surprise you how loud this little box can get, imagine how
the speakers must feel. Protection can be reset by powering off the unit and then powering
it back on. Cleaning up the coffee you spilled on yourself can be fixed with a cloth.
