AS-OST2 Audio Demonstrator

AS-OST2 – Mono vs. Stereo Audio Demonstrator

The AS-OST2 Audio Demonstrator showcases audio performance differences between mono and stereo playback using selectable speaker outputs and digital control interfaces. It supports both mono and stereo audio output and includes optical speaker switching capabilities.

Example Use Case

Two speakers are displayed. They can be activated individually or simultaneously:
• When one speaker is active (e.g., whole-house music), both left and right channels are routed to a single speaker.
• When both speakers are active (e.g., stereo movie mode), each speaker plays its designated left or right channel.
