Product Description
UR-223D is a dual channel true diversity wireless microphone system. The true diversity reception is more stable, with automatic dispatch, eliminate receive dead angle, avoid fault frequency phenomenon. UR-223D with advanced technology, stable performance, exquisite appearance, convenient operation and superior professional quality to win the market. This series is suitable for high requirement night club, multi-function room, hotels, and conference room and medium to large performance.
Performance Introduction
Wide range of audio outputs
It adopts 6.3mm unbalanced output and XLR balanced output synchronous output design, which is convenient to connect various audio processing equipment.
Super wide frequency range
Super wide frequency range UHF522MHz~936MHz, automatic selection, true diversity reception of dual-channel receiving circuit.
[IR] Infrared automatic frequency pairing
With [IR] infrared automatic frequency matching function, as long as the SYNC button is pressed for a short time, the transmitter can automatically and accurately lock the working frequency of the receiver.
PLL Phase Locked Oscillation Circuit
The stable PLL phase-locked oscillation circuit, combined with the "digital pilot" mute control function and the "noise detection" mute control function, can effectively block the noise and radio frequency interference of computer equipment, karaoke machines and DVDs in the working environment.
True diversity reception
The true diversity receiving system uses two receiving circuits with the same channel to reduce the noise and sound leakage caused by radio frequency interference.
[AFS] Automatic frequency search
With the [AFS] function of automatically searching for clean and non-interfering frequencies in the actual environment, after long pressing the ▲ button or the ▼ button for 3 seconds, it will automatically search and lock on the channel without interference in the actual working environment.
