XVive U45R4 - Wireless In-Ear Monitor Set

XVIVE U45R4 – Wireless In-Ear Monitor Set

The XVIVE U45R4 kit includes a U45T transmitter and four U45R4 receivers for professional in-ear monitoring in the 5.8 GHz band with True Diversity technology. It offers uncompressed 24-bit/48 kHz digital audio, latency less than 5 ms and a full frequency response of 20 Hz – 20 kHz, guaranteeing a clear and synchronized live signal. The system automatically scans six RF channels and selects the optimal one to avoid interference, with a range of up to 30 m line-of-sight. Both the transmitter and receivers are rechargeable (approx. 5 h of autonomy) and are housed in lightweight ABS housings (90 g transmitter, 118 g receiver), with an Aux/Line switch and a stereo minijack output for connecting headphones or IEMs.
