This is a Demo item, meaning it was used on a showroom floor so it is being sold at a reduced price. It may come without original packaging and may have minor blemishes. Some rack units may have deeper scratches on the chassis.
This is for 2 of the BX4 Bluetooth to XLR receivers.
The BX-4 is a Bluetooth receiver for the Bluetooth 4.0 chip. This chip can make the sound quality better and more compatible. Simply plug the 3-pin card into the mixer or active audio, and then use the Bluetooth function to wirelessly transmit to devices such as smart phones and PADs. By tapping the STEREO-LINK button, the BX-4 can be paired with another BX-4 (in the case where a BX-4 has been paired with a Bluetooth device such as a mobile phone or tablet) to transmit a signal to the audio signal.
