Please check that the packaging contains all system components as
listed above. If anything is missing, please contact your AKG dealer.
The SR 40 diversity is a stationary diversity receiver for use with all
WMS 40 and microtools Series transmitters. The SR 40 operates on
one fixed, quartz stabilized frequency in the 710 MHz to 865 MHz UHF
carrier frequency range and features a half-rack case.
The SR 40 diversity is a diversity receiver and uses two antennas in
order to receive the transmitter signal at two different spots. The di-
versity electronics will automatically activate the antenna that delivers
the better signal.
A preset squelch will mute the receiver if the received signal is too weak
so the related noise or the self-noise of the receiver will not become
audible when the transmitter is switched OFF.
Antennas: The diversity circuit will automatically activate the an-
tenna that provides the better signal.
ON/OFF: On/off pushbutton switch. If the DIVERSITY LEDs A and
B flash alternately and the RF/MUTE LED lights constantly, the
receiver is ON but receives no signal.
If the RF/OK, AF/OK, and only one of the two DIVERSITY LEDs
illuminate, the receiver is ON and receives signal.
When you switch the receiver OFF, all LEDs will extinguish.
RF/MUTE: This LED illuminates to indicate that no signal is being
received or the squelch is active. In both cases, the audio output
will be muted automatically.
RF/OK: This LED illuminates to indicate that the received field
strength of the transmitter signal is high enough to drive the input.
DIVERSITY LEDs A and B: Indicate which of the two receiving
antennas is active at any time.
Color code: The color of the AKG label indicates the carrier fre-
quency of your receiver. Transmitters and receivers tuned to the
same frequency are marked with identical colors.
