The Switchcraft 318BTS is a stereo Bluetooth audio receiver designed for use with mixing consoles, recording interfaces, and PAs capable of supplying phantom power. It's designed to receive audio from a Bluetooth transmitter and plug directly into two XLR inputs of a mixing console.
The 318BTS draws its power from the board's phantom power. Built-into the receiver is a DAC that converts audio from the Bluetooth source at 16 bits. The receiver offers a frequency response of 73 Hz to 17.5 kHz. It can handle stereo, stereo summed to mono, and mono sound sources. The unit will receive transmissions from up to 100' away. You can also power the 318BTS by means of a micro-USB to USB-A cable and any 5V phone charger brick (available separately).
