̈ Use the ̆/̄ buttons to select the desired transmission

Adjusting the sensitivity
SENSIT
Via the “SENSIT” menu, yo u can adjust the
radiomicrophone’s input sensitivity.
The input sensitivity is adjusted too high when close talking
distances, speakers with loud voices or loud music passages
cause overmodulation in the transmission link. When the
audio input level is excessively high (AF peak), the level
display for audio signal “AF” shows full deflection.
If, on the other hand, the sensitivity is adjusted too low, the
transmission link will be undermodulated, which would
result in a signal with high background noise.
The sensitivity is correctly adjusted when the level display
for audio signal “AF” shows full deflection only during
the loudest passages.
Note:
For monitoring the adjusted sensitivity, the transmitter’s
level display for audio signal “AF” always indicates the
audio level – even if the transmitter is muted.
The following figures are a guide to the best settings:
y Loud music/vocals: –30 to –20 dB
y Presentations: –20 to –10 dB
y Interviews: –10 to 0 dB
