User Manual
In this configuration the OptoLyzer4MOST Interface Box synchronizes the entire MOST Network to an
external S/PDIF audio source. The S/PDIF audio data is transported over the MOST Network to the
Amplifier 4 MOST. The OptoLyzer4MOST Interface Box is used for controlling the Amplifier 4 MOST.
