STV82x6
4 Audio Matrices
Audio Matrices
In addition to the sound carrier source (SIF), the STV82x6 accepts up to three analog stereo audio
inputs (2 VRMS SCART compatible) and one analog mono audio input (0.5 VRMS). These different
sources can go back out through four analog stereo audio outputs which are Loudspeaker +
Subwoofer and Headphone (1 VRMS) and two compatible SCART audio outputs (2 VRMS). An extra
digital stereo output (I²S compatible) is available for interfacing with a Dolby Pro Logic Decoder or
an external Digital-to-Analog Converter (DAC).
