The BTC-1X Bluetooth module is a transceiver that lets you wirelessly connect a portable media player, smartphone, or other Bluetooth equipped device. It transmits balanced line audio to the XStream Bluetooth input. The BTC-1X also supports the APTX codec, providing higher resolution audio quality. It can be installed anywhere and can extend Bluetooth reception beyond the normal limits. It can even be programmed with a custom passcode and room name for easy identification, using a USB cable and a free software download. Like all Russound Local Source Modules, the BTC-1X can be set to automatically interrupt an active audio signal. It integrates easily with the X5 via a dedicated CAT5 connection. No other connections or power supplies required.
