The UCR201 is a portable, high performance, triple- conversion, 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 dual-band 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.
