Adjusting Gain for Summed Outputs
Use the gain controls for each channel to create the overall mix balance. The front panel LEDs indicate the audio level for each
channel. If an overload occurs, the red LEDs will illuminate indicating that the internal limiter is active and the display will show
an overload message. To correct, adjust the overall gain balance.
Receiver Output Level
The following table describes the typical total system gain from the audio input to the receiver outputs:
Receiver Output Gain
Output Jack
System Gain (gain control = 0dB)
XLR (line setting)
+24 dB
XLR (mic setting)
-6 dB*
*This setting matches a typical wired SM58 audio signal level.
