This product is used for fiber optic long-distance transmission of 1-2 balanced audio signals and 1-2 video signals. The front-end balances the audio signal and video input directly, and through fiber optic transmission, the back-end output is connected to an active speaker or a power amplifier to drive the speaker. Using 16bit digital audio encoding, the system indicators meet or exceed the broadcasting grade A standard.
