The multi-function conference hall of a star-rated hotel in Yantai, Shandong Province, needed suitable wireless audio equipment for its daily schedule of meetings and events.
The client set three requirements: comprehensive functions with strong expansion capability and compatibility with all kinds of multimedia equipment; clear sound free of noise, delay and drop-outs so that every meeting runs smoothly; and simple installation and operation - no drilling, no cabling - to preserve the hall's appearance and let participants learn the system in minutes.
WAM-432 automatic smart wireless mixer with UB-222 boundary microphones
After repeated discussions, the client chose the WAM-432 automatic smart wireless mixer paired with UB-222 wireless boundary microphones, plus an UR-223D dual-channel true diversity wireless system with a UT-222 bodypack transmitter.
The UB-222 is a cleverly designed, easy-to-use wireless transmitter that mounts on the table without drilling or cabling, keeping the hall tidy and elegant. Its programmable touch switch offers three operating modes, and the metal body carries a high-contrast OLED display, a built-in high-pass filter and gain adjustment - ideal for video conferencing, government institutions and similar settings.
The WAM-432 receives over a 32 MHz bandwidth per channel with true diversity FM superheterodyne reception. It mixes four channels automatically for one to four speakers, supports a priority function and an adjustable sound-on gate, and its [AFS] auto-scan and SYNC pairing find an interference-free channel quickly. With the optional AMC-20 automatic audio-video controller it links mixer data, audio mixing and an HD camera for automatic camera tracking.
UR-223D dual-channel true diversity system with UT-222 bodypack
The UR-223D covers the wide UHF band of 522-936 MHz with true diversity reception that eliminates dead spots and prevents drop-outs. The receiver accepts a 32 MHz bandwidth in which up to ten systems can work side by side, while the transmitter spans 134 MHz for easy tuning and management. [AFS] auto-scanning and [IR] infrared pairing simplify setup, and the double squelch design - noise locking plus field-strength locking with digital pilot and noise detection - blocks interference from computers, jukeboxes, DVD players and other RF sources.
The UT-222 bodypack transmitter matches the same design language with a metal body, OLED display and built-in gain adjustment, and its standard mini XLR connector accepts most well-known headworn and lavalier microphones.
With clear, faithful sound, comprehensive functions and rich expansion, the Relacart combination fully meets the needs of the hotel's multi-function conference hall - a performance the client unanimously recognized.
