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. The Smart Squelch™ system is operated by a separate pilot tone and mutes the audio output directly at the output connector. The UCR201 features a menu-driven LCD and a three button control panel (MENU, SELECT Up and SELECT down). The combination of icons and text in the display provides convenient and efficient access to system functions and status using the menu button.  For example, the Main Window alone shows the pilot tone indicator, antenna diversity phase, RF level, audio level, receiver battery status and transmitter battery status.  It is also possible to bypass the pilot tone from the Main Window.  Other windows show operating frequency, audio output level, battery status in tenths of volts, test tone, and provide for selection of levels or functions using the SELECT buttons. The frequency scan mode provides a graphic means to observe all signals “on the air” within the unit’s frequency range in order to find useable operating frequencies free of interference
