Indicate the RF signal strength from the transmitter:
• Amber = Normal (-90 to -70 dBm)
• Red = Overload (greater than -25 dBm)
⑫ Audio LEDs
Indicate average and peak audio levels:
LED Audio Signal Level Description
Red (6) -0.1 dBFS Overload/ limiter
Yellow (5) -6 dBFS
Normal peaks
Yellow (4) -12 dBFS
Green (3) -20 dBFS
Signal PresentGreen (2) -30 dBFS
Green (1) -40 dBFS
Note: In Frequency Diversity mode, simultaneous blinking of the red and
yellow audio LEDs indicates that diversity audio has been routed to this
channel.
