Lectrosonics R400A Digital Hybrid Wireless UHF Diversity Receiver, Frequency Block 22 (563.200-588.700MHz)

A cutting-edge addition to your audio equipment, the R400A Digital Hybrid Wireless UHF Diversity Receiver, Frequency Block 22 (563.200-588.700MHz) is a high-performance, tabletop UHF receiver that is fully compatible with all Lectrosonics 400 Series Digital Hybrid Wireless transmitters, 200 Series, 100 Series analog transmitters, and IFB transmitters. It also works with some analog transmitters from other manufacturers, making it a versatile choice for your audio needs.

This advanced receiver boasts 256 user-selectable frequencies and proprietary audio processing that includes a digital signal processor (DSP) for ultra-low distortion. It delivers a superior signal-to-noise ratio and features two independent audio outputs, one balanced and one unbalanced, for maximum flexibility.

The R400A is equipped with a menu-driven graphic LCD display, providing a convenient way to view and alter user settings. It utilizes Digital Hybrid Wireless Technology, SmartTune auto frequency selection, and SmartDiversity enhanced reception for optimal performance.

The Digital Hybrid Wireless design is a revolutionary combination of digital audio with an analog FM radio link, providing both outstanding audio quality and exemplary, noise-free RF performance. It uses a patented algorithm to encode 24-bit digital audio information in the transmitter into an analog format, which is then transmitted over an analog FM wireless link. At the receiver, the signal is decoded to restore the original digital audio, eliminating compandor artifacts and producing an audio frequency response flat to 20 kHz.

The SmartTune feature overcomes the common problem of finding clear operating frequencies in RF saturated environments by automatically scanning all available frequencies in the receiver's frequency block and tuning to the one with the lowest RF interference.

SmartDiversity uses a microprocessor-controlled antenna phase combining to deal effectively with multipath dropouts. It analyzes both the incoming RF level and the RF level's rate of change to determine the optimum timing for phase switching and the optimum antenna phase.

The R400A also features SmartSquelch, which dynamically adjusts squelching behavior under varying conditions, delivering acceptable audio quality from otherwise unusable signals.

The receiver is designed to operate with Lectrosonics 400 Series transmitters for the best performance, but its digital signal processing allows it to operate with Lectrosonics 200 Series, 100 Series, and certain non-Lectrosonics transmitters in special compatibility modes.

The R400A is equipped with a Smart Noise Reduction algorithm, SmartNR, which removes hiss without sacrificing high frequency response. It also uses a DSP-based Pilot Tone to control the receiver audio muting (squelch), eliminating thumps, pops, and other transients.

The receiver offers both Balanced (XLR) audio output and Unbalanced (1/4-inch jack) Line Out and Monitor output, each controlled by their own digital attenuator. The Unbalanced Output can drive Low-Z headphones to a modest level, making it also suitable for system monitoring.

In summary, the R400A Digital Hybrid Wireless UHF Diversity Receiver, Frequency Block 22 (563.200-588.700MHz) is a sophisticated, state-of-the-art device that offers high-tech features and innovative solutions for your audio needs.
