ELECTRICAL CHARACTERISTICS TEST METHOD (Pin No is FP)
It omits the SW.No accorded with signal input pin because it is already
written in Table .
SW A,SW1,SW3,SW5 is in side a if there is not defined specially.
Icc1,Icc2,Circuit current(no signal)
The condition is shown as Table . Set SW19 to GND(or OPEN) and SW A
to side b, measure the current by current meter A. The current is as
Icc1(Icc2).
VDC1,VDC2 Output DC voltage
Set SW19 to GND (or OPEN), measure the DC voltage of
T.P.35(T.P.30,T.P.27) when there is no signal input.The DC voltage is as
VDC1(or VDC2).
VDC3,VDC4 Output DC voltage
Measure the DC voltage of T.P.25 same as Table, the DC voltage is as
VDC3(or VDC4).
Vimax1,Vimax2 Maximum allowable Input
Set SW19 to GND, SG1 as the input signal of Pin 2.Rising up the
amplitude of SG1 slowly, read the amplitude of input signal when the output
waveform is distorted. The amplitude is as Vimax1. And measure Vimax1
when SG2 as the input signal of Pin 5,Pin 7 in same way. Next, set SW to
OPEN, measure Vimax2 when SG2 as the input signal of Pin11, 13, 16.
Gv1, Gv1,GV2,
1. The condition is shown as Table .
2. Set SW19 to GND, SG2 as the input signal of Pin 2. At this time, read the
amplitude output from T.P 35. The amplitude is as VOR1.
3. Voltage gain Gv1 is
4. The method as same as 2 and 3, measure the voltage gain Gv1 when
SG2 as the input signal of Pin 5, 7.
5. The difference of each channel relative voltage gain is as
6. Set SW19 to OPEN, measure Gv2,
Gv3,Gv4,Voltage gain
1. The condition is shown as Table . This test is by active probe.
2. Measure the amplitude output from T.P.25.
3. Measure the GV3,GV4 by the same way as Gv1,
Fc1,
1. The condition is shown as Table . This test is by active probe.
2. Set SW19 to GND, SG2 as the input signal of Pin 2. Measure the
amplitude output from T.P.35.The amplitude is as VOR1.By the same way,
measure the output when SG4 is as input signal of Pin 2, the output is as
VOR2.
3. The frequency characteristic Fc1 is
4. The method as same as 2 and 3, measure the frequency Fc1 when input
signal to Pin 5, 7.
5. The difference between of each channel frequency characteristic is as
6. Set SW19 to OPEN, measure Fc2, Fc2.

Fc3,Fc4 Frequency characteristic
By the same way as Table measure the Fc3, Fc4 when SG5 of input
signal.
C.T.I.1,C.T.I.2 Crosstalk between two Input
1. The condition is shown as Table. This test is by active prove.
2. Set SW19 to GND, SG3 as the input signal of Pin 2. Measure the
amplitude output from T.P.35.The amplitude is as VOR3.
3. Set SW19 to OPEN, measure the amplitude output from T.P.35. The
amplitude is as VOR3'.
4. The crosstalk between two inputs C.T.I.1 is
5. By the same way, measure the crosstalk between two inputs when SG3
as the input signal of Pin5, Pin 7.
6. Next, set SW19 to OPEN, SG3 as the input signal of Pin 11, measure
the amplitude output from T.P.35. The amplitude is as VOR4.
7. Set SW19 to GND, measure the amplitude output from T.P.35. The
amplitude is as VOR4'.
8. The crosstalk between two inputs C.T.I.2 is
9. By the same way, measure the crosstalk between channels when SG3
as the input signal of Pin 13,16.
C.T.I.3,C.T.I.4 Crosstalk between two input
Set SG4 as the input signal, and then the same method as Table, measure
C.T.I.3, C.T.I.4.
C.T.C.1,C.T.C.2 Crosstalk between channel
1. The condition is as Table .This test is by active prove.
2. Set SW19 to GND, SG3 as the input signal of Pin 2. Measure the
amplitude output from T.P.35. The amplitude is as VOR5.
3. Next, measure T.P.30, T.P.27 in the same state, and the amplitude is as
VOG 5, VOB 5.
4. The crosstalk between channels C.T.C.1 is
C.T.C1= 20 LOG
C.T.I.1 = 20 LOG
C.T.I.2 = 20 LOG
