Engineered with cutting-edge technology, this receiver excels in environments where audio fidelity is paramount, delivering crystal-clear sound with minimal interference. Its hybrid design merges the best of digital and analog audio processing, ensuring a robust signal even in challenging conditions.\u003c\/p\u003e  \u003cp\u003eThis high-performance, triple-conversion, frequency synthesized UHF receiver is fully compatible with all Lectrosonics 400 series transmitters, as well as a number of analog models. The proprietary audio processing includes a DSP (digital signal processor) for very low distortion and a superior signal-to-noise ratio. This DSP eliminates a compandor and its artifacts, providing exceptional audio quality when operating in its native hybrid mode. Special DSP algorithms also ensure compatibility with Lectrosonics 100 and 200 Series analog transmitters.\u003c\/p\u003e  \u003cp\u003eWith a rugged chassis and intuitive interface, the R400a is built for the rigors of live performance, film production, and broadcast applications. It features advanced diversity reception, known as SmartDiversity™, which enhances signal stability by utilizing two antennas to capture the best signal. This ensures that your audio remains consistent and high-quality, regardless of the distance or obstacles between the transmitter and receiver.\u003c\/p\u003e  \u003cp\u003eThe R400a is equipped with SmartTune™ for auto frequency selection and offers 256 selectable UHF frequencies, ensuring versatility for various audio applications. The unit's easy-to-read graphics type backlit LCD display provides real-time information on battery status, signal strength, audio levels, and operating frequency, making it simple for users to monitor their setup on the fly. Additionally, a built-in RF spectrum analyzer allows for site surveys to find interference-free operating frequencies, recording RF activity across the tuning range for quick identification of optimal channels.\u003c\/p\u003e  \u003ch2\u003eKey Features\u003c\/h2\u003e \u003cul\u003e     \u003cli\u003eDigital Hybrid Wireless® technology (U.S. Patent #7,225,135) for superior sound quality\u003c\/li\u003e     \u003cli\u003eSmartSquelch™ and SmartDiversity™ for enhanced reception and noise management\u003c\/li\u003e     \u003cli\u003e256 selectable UHF frequencies for flexible audio solutions\u003c\/li\u003e     \u003cli\u003eLow noise, robust RF front end with RF-controlled digital noise filters\u003c\/li\u003e     \u003cli\u003eRugged and durable chassis designed for professional use\u003c\/li\u003e     \u003cli\u003eReal-time monitoring with a graphics type backlit LCD display\u003c\/li\u003e \u003c\/ul\u003e  \u003ch2\u003eTechnical Specifications\u003c\/h2\u003e \u003cp\u003e\u003cstrong\u003eFrequency Range\u003c\/strong\u003e\u003cbr\u003e 470 to 608 MHz\u003c\/p\u003e \u003cp\u003e\u003cstrong\u003eOperating Frequencies (MHz)\u003c\/strong\u003e\u003cbr\u003e Block 470: 470.100 - 495.600\u003cbr\u003e Block 19: 486.400 - 511.900\u003cbr\u003e Block 20: 512.000 - 537.500\u003cbr\u003e Block 21: 537.600 - 563.100\u003cbr\u003e Block 22: 563.200 - 588.700\u003cbr\u003e Block 23: 588.800 - 607.900\u003cbr\u003e 614.100 - 614.300\u003c\/p\u003e \u003cp\u003e\u003cstrong\u003eFrequency Adjustment Range\u003c\/strong\u003e\u003cbr\u003e 25.5 MHz in 100 kHz steps\u003c\/p\u003e \u003cp\u003e\u003cstrong\u003eChannel Separation\u003c\/strong\u003e\u003cbr\u003e 100 kHz\u003c\/p\u003e \u003cp\u003e\u003cstrong\u003eReceiver Type\u003c\/strong\u003e\u003cbr\u003e Triple conversion, superheterodyne, 244 MHz, 10.7 MHz and 300 kHz\u003c\/p\u003e \u003cp\u003e\u003cstrong\u003eFrequency Stability\u003c\/strong\u003e\u003cbr\u003e ±0.001 %\u003c\/p\u003e \u003cp\u003e\u003cstrong\u003eFront End Bandwidth\u003c\/strong\u003e\u003cbr\u003e ±30 MHz @ -3 dB\u003c\/p\u003e \u003cp\u003e\u003cstrong\u003eSensitivity\u003c\/strong\u003e\u003cbr\u003e 20 dB Sinad: 1 uV (-107 dBm), A weighted\u003cbr\u003e 60 dB Quieting: 1.5 uV (-104 dBm), A weighted\u003c\/p\u003e \u003cp\u003e\u003cstrong\u003eSquelch Quieting\u003c\/strong\u003e\u003cbr\u003e Greater than 100 dB\u003c\/p\u003e \u003cp\u003e\u003cstrong\u003eAM Rejection\u003c\/strong\u003e\u003cbr\u003e Greater than 60 dB, 2 uV to 1 Volt (Undetectable after processing)\u003c\/p\u003e \u003cp\u003e\u003cstrong\u003eModulation Acceptance\u003c\/strong\u003e\u003cbr\u003e 85 kHz\u003c\/p\u003e \u003cp\u003e\u003cstrong\u003eImage and Spurious Rejection\u003c\/strong\u003e\u003cbr\u003e 85 dB\u003c\/p\u003e \u003cp\u003e\u003cstrong\u003eThird Order Intercept\u003c\/strong\u003e\u003cbr\u003e 0 dBm\u003c\/p\u003e \u003cp\u003e\u003cstrong\u003eDiversity Method\u003c\/strong\u003e\u003cbr\u003e Phased antenna combining - SmartDiversity™\u003c\/p\u003e \u003cp\u003e\u003cstrong\u003eFM Detector\u003c\/strong\u003e\u003cbr\u003e Digital Pulse Counting Detector operating at 300 kHz\u003c\/p\u003e \u003cp\u003e\u003cstrong\u003eAntenna Inputs\u003c\/strong\u003e\u003cbr\u003e Dual BNC female, 50 Ohm impedance\u003c\/p\u003e \u003cp\u003e\u003cstrong\u003eAudio Outputs Rear Panel\u003c\/strong\u003e\u003cbr\u003e Independent balanced XLR adjustable from -50 dBu to +5 dBu in 1 dB steps.
