Frequently Asked Questions - OPT41AU Blustream

What is the Blustream OPT41AU?

The OPT41AU is a 4-Way Optical Audio Switch with a built-in DAC, allowing you to connect up to four optical audio sources and output to optical, coaxial, or analogue stereo simultaneously.

How do I switch between optical inputs?

You can toggle between the four optical inputs using the Select button on the front panel or by pressing the numbered input buttons (1-4) on the included IR remote control.

Can I use this device with a soundbar?

Yes, the OPT41AU is designed for integrating multiple audio sources with a soundbar, providing both digital and analogue audio outputs.
