Lectrosonics CR185 - Manual (Page 8)

OPERATING INSTRUCTIONS
1) Connect the power cord or install the battery.
2) Attach and extend the antenna.
3) Connect the audio cable.
4) Set the front panel switch to either "EXT" or "INT", depending upon the power source. Check
to see that the red POWER LED lights up.
5) THIS IS PERHAPS THE MOST IMPORTANT STEP IN THE SET UP PROCEDURE. Adjust
the transmitter "gain". See your transmitter manual (Operating Instructions section) for
specific directions on the proper gain adjustment of your particular transmitter.
6) Adjust the output 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. 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. The CR185 output was designed to drive microphone level inputs. The output signal
level ranges from -50dBV with the output control fully counter clockwise to -20dBV with the
output control fully clockwise.
INDICATOR QUICK REFERENCE
(Refer to Controls and Functions section for more detailed descriptions)
RF - This 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 LED lights up when the receiver is properly connected to a power supply and
switched on. It indicates proper battery voltage when the receiver is using a battery.
MODULATION - The "-20" LED lights up when an audio signal is present at an adequate level to
produce a good signal to noise ratio. The "0dB" LED lights up when the audio level is high and
the signal is being compressed in the transmitter. An extremely high audio level may cause
distortion.
