UCR201 GENERAL TECHNICAL DESCRIPTION INTRODUCTION The UCR201 is a portable, high performance, tripleconversion, frequency synthesized, UHF receiver fully compatible with all Lectrosonics 200 series transmitters. The RF performance is extremely stable over a very wide temperature range, making the UCR201 perfectly suited to the rough environmental conditions found in the field. The proprietary audio processing includes a dualband compandor for very low distortion and a superior signal to noise ratio.
UHF Wireless Diversity Receiver SURFACE ACOUSTIC WAVE (SAW) FILTER A state-of-the-art SAW filter on the 244 MHz IF amplifier offers sharp skirts, constant group delay, and wide bandwidth in one filter. Though expensive, this special type of filter allows primary filtering as early as possible, at as high a frequency as possible and before high gain is applied to the signal. Since these filters are made of quartz, they are very temperature stable.
UCR201 protects the unit when an external power source is used. This fuse resets if the power supply is disconnected for 15 seconds or longer. LCD The front panel LCD offers four primary windows. Pressing the MENU button rotates through each of these windows. If the battery gets low on either the UCR201 or the associated transmitter, a message will interrupt the display every few seconds stating “LOW RX BATTERY” or “LOW TX BATTERY.

UHF Wireless Diversity Receiver ANTENNA USE AND PLACEMENT The receiver is supplied with two fixed antennas. It is good to position the receiver so that there is a direct “line of sight” between the transmitter and the receiver antenna. In situations where the operating range is less than about 100 feet, the antenna positioning is much less critical. may also improve or deteriorate as the crowd fills or empties the room, or when the transmitter or receiver is moved to a different location.
UCR201 INSTALLATION AND OPERATING INSTRUCTIONS 1. Install a fresh battery or connect an external power source to the UCR201. Output Level Adjust 4. Set the Power ON/OFF switch to ON and verify that the LCD panel activates. 5. Adjust the transmitter gain. THIS IS PERHAPS THE MOST IMPORTANT STEP IN THE SET UP PROCEDURE. Refer to your transmitter manual’s Operating Instructions section for details on how to adjust the transmitter gain.
