This Bluetooth transmitter/receiver opens up new possibilities with Bluetooth standard 5.0. Connect your home entertainment hardware optically via Toslink cable or analog via stereo RCA and send pure sound wirelessly to or from the BTR Evolution 5.0, the new multitool for your audio enjoyment. As a 2-in-1 adapter, it excels in both transmitting and receiving, each with Bluetooth 5.0 standard and backward compatibility. Switching between transmit and receive modes is possible with a toggle switch. Pair the Oehlbach BTR Evolution 5.0 with two devices and enjoy double CD quality with aptX HD. With low-latency functionality and a delay of less than 40 milliseconds, you won't notice the wireless transmission and can simply enjoy music and other sounds just like with an Oehlbach cable connection. It sounds great and looks good with its elegant, high-quality design in any home.
