● Shared outputs for headphone and certain loudspeakers (surround channels);
● Analog matrix with:
— Five external inputs:
Four SCART inputs (2 V_RMS capable)
One analog mono input (0.5 V_RMS)
— One internal input from a digital matrix via a DAC
— Three external outputs (2 V_RMS capable)
— One internal output for the digital matrix (using an internal ADC)
● Digital matrix with:
— Three input modes (demodulator/SCART, SCART only and I²S)
— Three stereo outputs (loudspeakers, headphone and SCART)
● High-end audio DAC
● S/PDIF output for connection with an external amplifier/decoder
● Internal multiplexer for the S/PDIF output (to share the internal S/PDIF output and the S/PDIF
output generated by the external decoder of the digital broadcast)
