Compact Receiver Introduction Thank you for selecting the Lectrosonics multi-frequency, UCR100 Receiver. The UCR100 is the result of extensive engineering experience with the very latest microprocessor advancements and technology. The Lectrosonics 100 System Receiver and companion transmitter are designed expressly for the most discriminating videographer and for other wireless applications needing superior audio quality, flexible operation, and outstanding durability.
UCR100 General Technical Description Features The multi-frequency UCR100 FM Receiver is designed to operate with the Lectrosonics UM100 Transmitter and features microprocessor control of 256 frequencies of operation within each frequency block. Each block covers 25.5 MHz with 0.1 MHz frequency spacing. Any one of ten different frequency blocks are factory available from 537.6 MHz to 805.5 MHz (except 608 to 614 MHz).
Compact Receiver Controls & Functions Power LED Power ON/OFF Switch Antenna Frequency Select Switches (Under Door) RF LED Modulation LEDs Audio LEVEL Control Audio OUT Jack Modulation LEDs The two modulation LED’s indicate the modulation (audio level) of the incoming signal and can be used for proper adjustment of the transmitter’s mic or audio level. The -20 LED glows when the transmitter modulation is at a high enough level to produce a good audio signalto-noise ratio.
UCR100 Audio Level Control Attenuates the audio output level of the receiver to match the input requirements of the equipment with which it is used. The 3.5mm Mini output jack on the front panel provides an audio output at adjustable levels for low or high impedance, unbalanced inputs. At the extreme counter-clockwise position of the control knob, the output level of the Mini jack will be -50dBV at full modulation. In the fully clockwise position, the output level will be 0dBV (1 Vrms) at full modulation.
Compact Receiver 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”.
