Product Description

The AU-D21 is an Optical (Toslink) Audio Switcher, select between two Optical (Toslink) sources to one Optical (Toslink) output whilst maintaining a reliable and loss-less audio signal transmission.

With commercial and residential AV Source devices increasingly featuring a digital optical audio output, it can be frustrating that many AV amplifiers only feature a single optical audio input.
