Lectrosonics SR170AC - Manual (Page 5)

SYSTEM SETUP AND OPERATION
1) CONNECT POWER CORD - On your external power source, be sure the center pin is
positive(+).
2) ATTACH AND EXTEND THE ANTENNA
3) CONNECT THE AUDIO CABLE
4) SET FRONT PANEL SWITCH TO "ON."
Check to see that the red POWER LED lights up.
5) ADJUST TRANSMITTER "GAIN."
This is perhaps the most important step in the set up procedure. (see your transmitter manual
for specific instructions on the proper gain adjustment of your transmitter)
6) ADJUST AUDIO OUTPUT LEVEL CONTROL according to the type of input on your equipment.
The input levels on different VCR’s and PA equipment vary which may require that you set the
OUTPUT control in an intermediate position somewhere in between the MIN and MAX positions of
the knob. Try different settings and listen to the results. If the output of the receiver is too high,
you may hear distortion or a loss of the natural dynamics of the audio signal. If the output is too
low, you may hear steady noise (hiss) along with the audio.
INDICATORS
RF - This red LED lights up when the transmitter is turned on. This indicates that the receiver is getting
an adequate RF signal (carrier) from the transmitter.
POWER - This red LED lights up when the receiver is properly connected to a power supply and
switched on.
MODULATION - The red LED (marked -20) lights up when an audio signal is present at an adequate
level to produce a good signal to noise ratio. The red LED (marked 0dB) lights up when the audio
level is too high and is being compressed in the transmitter. An extremely high audio level may also
cause distortion.
