Studio Master W4U-RL4 | 4 Channel Digital Wireless System with 4 Beltpack Transmitters

STUDIO MASTER W4URL4  (Studio Master W4U-RL4 Bodypack System)

No matter in terms of language, speech, meeting, host or live performance, it can be used in any situation, place and time to get rid of complex on-site layout needs and provide the most reliable links, and present the most authentic sound restoration at every moment. The main applications for business conmunication: conferences, primary and secondary education, hotels, higher education, religious places, enterprises and governments.

FEATURES:

Real time noise suppression: real-time elimination of background noise, so that users can fully focus onthe voice in the call.

Automatic frequency coordination: the system automatically scans the available spectrum and selects clear and clean transmission channels to achieve the best performance.

Interference avoidance: the system can detect and avoid unexpected interference, and channel adjustment can prevent interference to audio.

RF efficiency: perfect PLL RS stabilization technology can provide better sound quality and wider dynamic range, to ensure the highest quality sound in any environment.

Encryption: standard AES-128 encryption of audio and data can ensure the privacy of conference content Data control: provides control functions for central control, audio and speaker equipment, realizing video tracking, voice control. Etc.

User-friendly interface: high-definition TFT color display screen provides a complete overview of system information, and enable users to set up shortcuts.

Power monitoring: real-time power monitoring of each transmitter, ensuring uninterrupted use in the field. Electronic volume: 30-level electronic volume control, can precisely control the volume of each channel. Multi-platform systems work together: the receiver provides 2/4/8 channels. The transmitter provides handheld, backpack, and desktop conference microphones. Users can mix and match them freely.
One-key frequency matching: one-key fast data synchronization between the receiver and the transmitter, convenient and fast.

Multiple audio interface outputs: each channel has an independent balanced audio output XLR (male), a mixed output TS(6.35mm 2-core), and a cascade output TS (6.35mm 2-core).

Audio cascade: When multiple receivers are used in stacked, all receivers can achieve unified audio management through the cascade audio interface.
