Doing the soundcheck
Soundcheck
By doing a soundcheck, you can check the reception area for field strength
gaps (“dropouts”) which cannot be compensated for by the receiver’s
diversity circuitry. You can do the soundcheck without the help of another
person.
̈ Switch the transmitter on.
̈ Select the “Soundcheck” menu. The soundcheck is started immediately.
̈ With the transmitter, walk up and down the transmission area.
̈ Press the ̄ button on the receiver to terminate the soundcheck and to
display the result of the soundcheck. The level displays “RF” and “AF” will
indicate the lowest RF and the highest AF level of the received
transmitter.
Optimize the RF level by repositioning the receiving antennas.
The audio level should be as high as possible (max. 0 dB) without the level
display for audio signal “AF” showing full deflection (see the section
“Adjusting the sensitivity“ in the operating manual of the transmitter).
If both receiving antennas are connected and aligned, the diversity
displays I and II appear on the display panel.
If no transmitter is being received, the “MUTE” display appears on the
display panel.
̈ To do another soundcheck (e.g. with an improved antenna arrangement,
another transmitter position or a new transmitter sensitivity), press the
̆ button.
