When using DVI-HDMI cable, HDMI input
has no digital audio signal, Video3 audio
input is selected automatically.
● Audio signal processing stage
● Description
SIF signal from the TUNER is sent to IC5001(MTS decoder), Video1 audio input signal is sent to IC5001, and
selected signal is sent to IC5101(Audio controller). Video2/3 audio input signals are sent to IC5101. Digital-TV or
HDMI audio signal is output from IC5500 and sent to IC5101 via IC6300(Amp.).
The sound volume and sound quality are controlled in IC5101 by IIC bus. The output audio signals from pins 14
and 25 of IC5101 are sent to pins 2 and 4 of IC001(Audio Amp.) and amplified and output from pins 8 and 12 as
the signals to drive speakers.
Woofer output; Woofer signal is output from pin 1 of IC5101 and sent to pin 2 of IC5181 (Woofer
amp.), amplified and output from pin 7 for woofer speaker. The woofer level can be
selected Off/Low/Mid/High with user menu.
Audio monitor output; Audio monitor output signal is output from pins 11 and 28 of IC5101.
Digital audio output; Digital-TV and HDMI audio signals are decoded in IC5500 and SPDIF signal is out-
put from IC5500.
