The BTFLEX enables mixing consoles and active PA speakers to receive wireless audio over Bluetooth from smartphones, tablet PCs, and laptops simply by plugging the BTFLEX into an audio system's XLR input and pairing it with a bluetooth device.
In MONO model, the left and right channels of a stereo signal are summed to mono and outputted from one XLR connector, whereas in STEREO model, the left signal send out from the bottom XLR output and the right signal send out from the top XLR output. The BTFLEX then offers a third LINK mode, this allows the user to use a pair of BTFLEX and stereo link them so that Left audio channel is outputted from one BTFLEX and the Right audio channel is outputted from the second BTFLEX.
The BTFLEX offers USB-C power input in addition to its own internal rechargeable battery offering the ability to operate wire free, ideally for use with portable PA systems.
