Even though the HD6 has a built-in Bluetooth receiver, the HD6 are extremely versatile and can be used with a number of different devices, both digital and analog. There two analog inputs, a mini-stereo and RCA input, on the rear panel so you can directly connect any product with a line-level/preamp audio output, such as a turntable. The HD6s also have an optical input that utilizes the speakers' built-in DAC, so any source that has a digital optical output can be used directly with the speakers, such as the optical output of your television or computer.
Is the HD6 designed only for use with Bluetooth devices?
