Lectrosonics UCR110 - Manual (Page 6)

OPERATING INSTRUCTIONS
1. Install the battery.
2. Set the “FREQUENCY” switches on the side panel to match the switches on the Transmitter.
3. Connect the audio cable.
4. Set the front panel switch to ON. 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 LEVEL 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 UCR110 output was designed to drive camera line level inputs but can operate into camera MIC inputs if
the receiver output is reduced to prevent Automatic Limiting Control “pumping” in the camera. The output signal
level ranges from -50 dBV with the output control fully counter clockwise to 0 dBV with the output control fully
clockwise when the transmitter signal is at full modulation.
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 switched on. It indicates proper battery voltage when the receiver is
using a battery. See chart on page 7.
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 transmit­
ter. An extremely high audio level may cause distortion.
Review the transmitter instruction manual for proper adjustment and setup of the transmitter mic level or gain.
