R-0507 All-Metal 4-Channel UHF Wireless Microphone System 1-to-4
Run four handheld microphones from a single 1U rack receiver. The R-0507 pairs every channel over infrared in seconds — no menus, no manual frequency hunting — then holds a clean, low-noise signal across a wide working distance. All-metal handheld bodies, a rugged rack-mount receiver and balanced XLR outputs make it a dependable choice for stages, KTV rooms, conference halls, classrooms, live streams and outdoor events.
Key Features
- One-Touch Infrared Sync — Press once and the receiver matches each transmitter automatically - all four channels are live in seconds, no menu hunting.
- True 4-Channel Independence — Channel A / B / C / D each carry their own transmitter, frequency readout and level meter, so the full system can run at the same time without dropouts.
- All-Metal Handheld Transmitters — Solid metal bodies with dynamic capsules, on-board LCD frequency display and a tactile mute / power switch.
- Full Rear-Panel Connectivity — 4 balanced XLR outputs, a mixed output, DC input and dual antenna ports with detachable antennas for a clean install.
- Low-Noise, Long-Range Reception — Signal-to-noise ratio of ≥ 85 dB with an anti-interference design for stable transmission at distance.
- 3 - 6 Hours Per Charge — 800-1000 mAh replaceable battery packs with a Type-C charging interface - swap packs instead of stopping the show.
- Fits The Rig You Already Own — Connects to mixers, amplifiers, sound cards, trolley speakers and home-theatre systems.
