BX-4 is a Bluetooth receiver with 5.0 chip. This chip offers high quality sound and makes the compatibility and integral performance more optimizing. Just use 3-pin XLR to connect console or active speaker, then using Bluetooth to connect smart phone, pad such devices to realize wireless transmission. STEREO-LINK button helps BX-4 pairing with another BX-4 to transmit the signal to audio equipments. 1. USB CHARGE: charging interface supply power to devices. 2. POWER ON/OFF: push switch-turns the BX-4 on and off. 3. PAD 0dB -10dB: sensitivity attenuator, lower the input signal sensitivity and avoid signal overload and distortion. 4.
