MTS ADJUSTMENT
MTS Level Adjustment
1. Set the sound volume above 1.
Monoral signal: 400Hz, 100% modulation
2. Confirm "EX4" data is "5Ah".
3. Vary the "M01" bus data until the voltage to pin (39)
of IC3001 to become the value as stated below.
SETTING VOLTAGE
ADJ spec : 490
±
10mVrms
CHK spec: 490
±
20mVrms
Separation Adjustment
1. Input "SIGNAL 1" and vary the "M04" bus data to get
the minimun AC voltage to pin (39) of IC3001.
2. Input "SIGNAL 2" and vary the "M05" bus data to get
the minimun AC voltage to pin (39) of IC3001.
SIGNAL 1: 300Hz, 30% modulation, Lch only, NR-ON
SIGNAL 2: 3kHz, 30% modulation, Lch only, NR-ON
Note:
SIGNAL 1 Adj. for widebando
SIGNAL 2 Adj. for spectral
Check the output of the speaker at the maximum
volume as stated below.
Confirmation spec:
ADJ spec: above 25 dB
CHK spec: above 20 dB
