Signal Description – Audio / TV Output Connector (CN9)
SPK L/R
Left and right speaker output. These are the speaker outputs directly from the speaker
amplifier. Coupling capacitors must be used in order to avoid DC-currents in the speakers. If
the Audio Bracket is used these signals are supplied on the PCB. GND should be used as
return for each speaker. Maximum power: 0.5W@4 Ω load for each channel.
Mic / Mic Bias
The MIC signal is used for microphone input. This input is fed to the left microphone
channel.
Mic Bias provides 3.3V supplied through 3.2K Ω with capacitive decoupling to GND. This
signal may be used for bias of some microphone types.
Line-In L/R
Left and right line in signals.
Line-Out L/R
Left and right line out signals. Both signals are capacitor coupled and should have GND as
return.
Yout
Luminance output
Cout
Chrominance output
COMP
Composit video output
