Description
The R300 receiver is a compact, rack-ready wireless receiver designed to deliver reliable RF performance and clear audio in live and installed sound environments. It provides 32 preset channels and true antenna diversity to maintain stable wireless links. The receiver fits on a tabletop or in a 19-inch rack using available mounting kits.
Key features include ClearScan automatic channel selection, EZsync infrared frequency transfer, and detachable half-wave TNC antennas for distribution systems. ClearScan scans preset channels and picks the clearest option with a single button press. EZsync simplifies transmitter pairing by automatically programming matching frequencies via infrared.
Technically the R300 uses a synthesized PLL receiver architecture and supports multiple frequency bands: A 618 – 634 MHz, B 678 – 694 MHz, C 516 – 532 MHz, and E 850 – 865 MHz. Audio performance is specified with a frequency response of 80 Hz – 18 kHz ± 2 dB, signal-to-noise ratio greater than 100 dB A-weighted, and dynamic range over 95 dB. Distortion is specified under 1.0% with a typical 0.4% at 1 kHz and 40 kHz deviation.
Connectivity includes balanced and unbalanced audio outputs with adjustable unbalanced level and a maximum balanced output of 20 dBV at 40 kHz deviation. The unit accepts a 12-16 VDC power source and consumes up to 500 mA. Detachable TNC antennas allow integration with antenna splitters such as the APD4+ for multi-receiver racks.
The R300 is suitable for live vocals, instrument links, corporate presentations, and installed sound systems where reliable wireless performance is required. Its ClearScan and EZsync features reduce setup time and minimize RF interference issues in congested environments. The unit is road-ready and has a durable low-profile enclosure for touring and rental use.
Installation and everyday use are straightforward due to simple front-panel controls and an easy-to-read display. Rack-mount kits and front-mount antenna cables are available to adapt the receiver to permanent installations. Overall, the R300 balances essential professional features and user-friendly operation in a compact wireless receiver package.
