̈ Use the ̆/̄ buttons to select the desired transmission
frequency. Transmission frequencies are tunable in
25-kHz steps within a switching bandwidth of 36 MHz
max. For intermodulation-free frequencies, please refer
to the enclosed frequency table.
Adjusting the sensitivity
SENSIT
Via the “SENSIT” menu, you can adjust the transmitter’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
In order to be able to use highly sensitive directional
condenser microphones, the plug-on transmitter offers a
sensitivity range extended by 20 dB.
With the transmitter plugged onto a directional condenser
microphone, the following figures are a guide to the best
settings:
y Loud music/vocals: –50 to –40 dB
y Presentations: –40 to –30 dB
y Interviews: –30 to –20 dB
