4-7-8. MIC 2 Demodulation Adjustment

Note :

Perform this adjustment only when replacing

T301/

AA-90 board.

Equipment

Oscilloscope, Audio generator

To be extended :

AA-90 board

AFM-15 board (CA-TX7/TX7P)

Preparations :

1. AUDIO SELECT switch (CAMERA/CA-MIC/CA-LINE)/

CA-TX7/TX7P

→

"CA-LINE"

2. Input the 1 kHz sine wave signal of the audio generator to

CH 2 of MIC IN (rear panel) on the CA-TX7/TX7P.

• Fig-2 (Refer to 4-1-5. Audio connection.)

3. Adjust the output level control of audio generator so that

the pin 17 (GND : pin 12)/AFM-15 board is 220 mV p-p.

Test point :

TP11 (GND : E2)/AA-90 board

Adjustment Procedures :

1. Adjust the white core of

T301/AA-90 board slowly so

that the DC level at TP11 (GND : E2) /AA-90 board is

1.24

0.01 V dc.

2. Set the input range of oscilloscope to AC mode, and adjust

the blue core of

T301/AA-90 board so that the sine wave

is minimum.

3. Repeat procedure 1.
