B-7 Pro is a professional wireless in-ear monitoring system operating in the 2.4GHz band. A fully digital signal path delivers high quality stereo audio with minimal latency and a range of up to 50m. The receiver (RX) can be clip-mounted to clothing or a guitar strap and can be re-charged from the main transmitter (TX) or via USB-C. The TX is itself rechargeable or can operate directly from the supplied 9Vdc power adaptor and can even double as a USB audio interface for recording to a PC or Mac computer. Onboard the TX is a full colour display showing signal and battery status for both TX and RX units and serves a settings menu for adjusting signal levels, display and transmission preferences. In addition to balanced left & right signal inputs, there is a stereo Aux input and a wired Phones output. A screw adaptor is also provided to enable the transmitter to connect with standard action camera clamps if preferred for mounting to a stand or fixture. In summary, the B-7 Pro offers the latest wireless technology with unique features to deliver reliable high-quality monitoring for even the most demanding of performers.
