In addition to the sound carrier source (SIF), the STV82x6 accepts up to three analog stereo audio
inputs (2 V
RMS
SCART compatible) and one analog mono audio input (0.5 V
RMS
). These different
sources can go back out through four analog stereo audio outputs which are Loudspeaker +
Subwoofer and Headphone (1 V
RMS
) and two compatible SCART audio outputs (2 V
RMS
). 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).
