1b VOLUME: The VOLUME pot matches the SR 80s output level  
to the input sensitivity of your mixer or amplifier.  
1c SQUELCH: The squelch circuit switches the receiver off if the  
received signal is too weak, in order to suppress the related  
noise or the residual noise of the receiver while the transmitter  
is off. Set the SQUELCH control to minimum before first switch-  
ing the receiver on. (For details, refer to section 9.)  
1d CHANNEL: This rotary switch selects the desired carrier fre-  
quency or its alternative frequencies.  
1e Telescoping antennas: The SR 80 is a diversity receiver and  
uses two antennas in order to receive the transmitter signal at  
two different spots. The diversity electronics will automatically  
activate the antenna that delivers the better signal.

This is necessary to provide the minimum frequency spacing re-  
quired for intermodulation-free multichannel operation.  
Im p o rta n t: Prior to changing a carrier frequency, b e su re to  
sw itch th e tra n sm itte r O FF. To activate the new carrier  
frequency, switch the transmitter back ON. (If you try to change  
the carrier frequency while power to the transmitter is on, the  
frequency will remain the same.)  
9 .6 . Im p o rta n t Hin ts fo r Re lia b le O p e ra tio n  
The propagation of RF radiation is subject to certain physical laws  
that you need to take into account in order to obtain trouble-free  
performance from any wireless microphone system. Here are a  
few useful hints on how to avoid problems such as sudden noise  
surges, phasiness (whizzing, whirring), dropouts, or clicks:  
1. In a multichannel system, always leave power to all transmitters  
on. To cut the transmitter signal, use the MUTE switch only.  
2. Keep a minimum transmitter to receiver distance of 16 ft. (5 m).  
3. Make sure the transmitter will never be farther away from the  
receiver than 164 ft. (50 m).  
4. Make sure there is a direct line of sight between the transmitter  
and receiver.  
5. Keep any two transmitters at least 40 inches (1 m) apart.  
If this is impractical (for instance, during ”love duets”), check  
prior to the performance what frequencies will work best at  
close quarters.  
6. Make sure the antenna of the bodypack transmitter will hang  
down freely throughout the performance and will not touch the  
user’s skin. The human body attenuates RF signals.  
7. Do not place the receiver in a recess in a wall or near sheet  
metal or wire structures. W ire mesh is a particularly efficient  
absorber of RF energy.  
8. Do not align antennas parallel to metal surfaces.  
9. Avoid lighting racks and fluorescent lamps. Dimmers and  
ballast circuits emit RF radiation.  
9 .4 .5 . An te n n a s  
For optimum reception, make sure to extend the two telescoping  
antennas (1e) exactly as far as specified for each Frequency Set  
in Table 1 on page 39.  
9 .5 . Sy ste m Ad ju stm e n ts  
1. Ha n d h e ld tra n sm itte r: Using the supplied screwdriver  
(1q), set the GAIN control (2e) so that on the receiver the green  
AF LED (1h) will light constantly and the red PEAK LED (1h) on  
the receiver and the status LED (2b) on the transmitter will only  
flash on the loudest signal peaks.  
Bo d y p a ck tra n sm itte r: Using the supplied screwdriver  
(1q), set the GAIN control (3j) so that the green AF LED (1h) on  
the receiver will light constantly and the status LED (3c) on the  
transmitter as well as the red PEAK LED (1h) on the receiver will  
only flash on the loudest signal peaks.  
2. The red PEAK LED (1h) on the receiver and/ or the status LED  
(2b, 3c) on the transmitter lighting brightly means the transmit-  
ter is overloaded. Turn the GAIN control (2e) or (3j) on the  
transmitter CCW to the point that the PEAK (1h) and status (3c)  
LEDs will only flash occasionally.  
3. Set the VOLUME control (1b) on the receiver so that the receiv-  
er output will optimally drive the connected device (e.g., mixer  
input). Refer to the instruction manual for the connected device.  
4. Check the performance area for "dead spots", i.e., places where  
the field strength seems to drop and reception deteriorates.  
If you find any dead spots, try to eliminate them by reposition-  
ing the receiver. If this does not help, avoid the dead spots.  
5. If unwanted noise becomes audible, turn the SQUELCH control  
(1c) CW just enough to suppress the noise.  
10.Avoid digital effects units and PCs. They, too emit RF radiation.  
1 0 . Cle a n in g  
To clean the transmitter and receiver surfaces, use a soft cloth  
moistened with methylated spirits or alcohol.  
The MUTE LED (1f) will light every time the squelch mutes the  
audio output of the receiver.  
Im p o rta n t: Never set the squelch threshold higher than abso-  
lutely necessary. The higher the squelch threshold, the lower the  
sensitivity of the receiver and thus the usable range between  
transmitter and receiver.  
6. Check the field strength of the received signal. If the RF LOW  
LED (1g) lights, reposition the receiver and/ or transmitter such  
that field strength will increase back to optimum (OK LED (1g)  
illuminating).  
7. The MUTE LED (1f) on the receiver illuminating means that the  
squelch is active.
