The 318BT plugs into a low impedance mic/line input using the Switchcraft male XLR balanced connector and is powered from the console or mic pre-amp's phantom power or via a micro USB jack on its side. So now I have wireless audio integrated into my studio's system without wiring, software or batteries.

The 318BT runs under the latest 4.0 Bluetooth standard to receive an audio stream from any BT-enabled device. I like the black-anodized aluminum case and the tiny LED on the front end that confirms pairing to the device.

I plugged the 318BT directly into the front panel Combo XLR connector of my Sunset Sound S1P Tutti Mic-Pre and used about 50dB of mic gain to raise the audio level to +4dBm line level for my Pro Tools interface. But I could have also just plugged it into any audio console's microphone channel just as well. The 318BT immediately "paired" up with my iPhone 6s and I was streaming my music directly.

The 318BT combines the left and right stereo channels into mono and I thought the 16-bit sound quality was fine for quickly playing iPhone music, YouTube videos and songwriters' song ideas, samples or demos--any reference track(s) during a busy session. I no longer have to connect using a wire to a -10dBv to +4dBM "bump box" (such as the Aphex 228) and then bring it up on the board in someway just to hear a musical idea.

I can leave the 318BT plugged into its own channel at the end of the mixer and it'll be at the ready whenever someone in the room pairs up their device. I could get about 75-feet away (depending on obstacles in the way) and maintain a solid connection. And if I went out of range momentarily, Bluetooth 4.0 would re-connect instantly when I got back in range with no big whoop.
