A Board Audio Processing - Panasonic LX600 Technical Information

A Board Audio Processing

Audio processing is performed on the A board. Audio signals from the
DVI, Component, and the Composite video input enter the Audio Switch
IC2006 where the desired input is selected. HDMI Audio is processed
and converted into a one bit digital audio format by the HDMI IF receiver,
IC5004. The HDMI audio bypasses the audio switch and enters IC4002
for selection and processing. The output of IC2006 is processed within
the Video/Audio controller IC4002. The Audio Output from the
Video/Audio controller is output to the speakers via the Audio Amplifier
IC2001 and pins 1 through 7 of connector A7. The Headphone amplifier
is activated when the headphones are plugged into the headphone jack
located on the G board. This action mutes the audio to the speakers by
disabling the Audio output Amplifier IC2001.
