2-channel multifrequency wireless receiver with 24-bit processor for high-end audio quality. Integrated MagicEQ enables amazing microphone modeling of hand-held microphones. Choose from 7 presets based on popular microphone models (e835, beta58, e935, D5, SM57, N/D767a, SM58) and 3 user-definable presets. Integrated Feedback Killer effectively eliminates feedback, providing maximum gain and increased clarity on every microphone. DSP programming and management via Ethernet port and intuitively operated PC software. High-quality true diversity reception. 2 license-free frequency ranges: 823-832MHz (Duplex Gap)and 863-865MHz. 10 groups with 90 fixed frequencies within 11 MHz switching bandwidth. Parallel operation of up to 9 systems is possible without any interference. Pilot tone technology (PLL) and noise squelch for interference-free operation. Operation range with line of sight approx. 80 meters. Automatic frequency scan (AFS) finds interface-free channels. Infrared interface for easy and error-free channel transfer to transmitters via infrared signal. LCDs for battery status of the transmitters, antenna A/B, RF reception level, AF audio level and frequency. Multiple units can be linked with network cables. Lock function avoids accidental changing of settings. XLR and 6.3 mm jack output. 2 detachable BNC antennas allow for use with the R-14D antenna divider. Matching hand-held microphone (UR-260D) optionally available. Delivery includes jack cable and power unit. Durable metal housing. 483 mm rack installation possible with supplied mounting brackets. License-free and approved in large parts of the EU (please check Duplex Gap on a country-by-country basis).
