Side Jack Panel
Figure 22
The Side Jack panel is the AV3 input in the Customer Menu. It has a Composite Video Input, SVHS Input, and
a Stereo Audio input. It also has a headphone output. If an SVHS connector is plugged into the Side Jack
panel, the Composite Video input is muted. The Audio inputs are designed so that if audio is plugged into only
one input, the signal will be fed to both the Left and Right Channel lines. The Front Detect line tells the
Microprocessor if an SVHS or Headphone is connected to the Side Jack panel. In normal operation, the
FRONT-DETECT line is approximately 1.05 volt. When a Headphone is plugged in, resistor 3295 is taken out
of the circuit causing the voltage to increase to 1.35 volts. The Microprocessor will activate the Mute line. With
only the SVHS connected, resistor 3289 is out of the circuit, causing the FRONT-DETECT line to increase to
1.99 volts. An indicator will appear in the Menu to indicate that SVHS is present on AV3. With both a SVHS
and Headphone connected to the Side Jack panel, both resistors are out of the circuit and the voltage will
increase to 3.39 volts. This will give the SVHS indication in the Menu and Mute the Audio. If the Side Jack
panel is disconnected while troubleshooting the set, the Audio will be muted.
