232C PWB (EXTERNAL CONTROL terminal)
This system is arranged to enable external control through the RS-232C. It is used when controlling this ma-
chine with a personal computer or the like. The RS-232C control signal applied to M2002 is led to the microcom-
puter through the RS connector, after the completion of interface processing with the outside (processing for
voltage conversion) with the aid of the RS-232C driver (IC2001).
AUDIO PWB Block Operation
At Pin 2 (Channel L) and Pin 4 (Channel R) of the AB connector, a signal input of the audio input terminal is
available. This signal has been amplified approximately twice. The input signal passes through the buffer circuit
and is entered in the sound processor. In this sound processor, various controls are carried out, such as sound
volume control, right and left balancing, bass tone adjustment, treble tone adjustment, silencing, etc.
Using the sound processor, the audio signal after the adjustment of tone quality and sound volume is amplified to
the output level by the use of the main amplifier. The output is transferred to the speaker terminals through the LM
and RM connectors.
The control signal for the sound processor is applied to Pins 1 and 2 of the AE connector.
