I/O TERMINAL VOLTAGE (FIGURE 10)

This is the DC voltage of input and output.

Because the input and the output are nearly equal, only the

output is measured.

1) Pin 5 is in the open condition, or high level.

2) Connect a DC volt meter to Pin 3 and measure.

This value is the terminal voltage of 1-Ach.

3) Next, connect Pin 5 to the GND, or low level.

4) Measure in the same way.

This value is the terminal voltage of 1-Bch.

SEPARATION (FIGURE 9)

This is the cross talk between 1ch and 2ch.

1) Control level is free for Pin 5 and Pin 8.

2) Connect AC volt meters to Pin 4 (or Pin 2) and Pin 10.

3) Connect Pin 9 and Pin 11 to GND through capacitors

and a resistance.

4) Input a sine wave (10 kHz, 1 Vrms) to Pin 2 and Pin 4.

5) Measure the level of Pin 4 and name this V5.

6) Measure the level of Pin 10 and name this V6.

7) Calculate:

SEP = 20 Log (V6 / V5)

This value is the separation to 2ch from 1ch.

OUTPUT TERMINAL DIFFERENCE

This is the DC output voltage difference between Ach and

Bch. This is calculated by using values measured at the

I/O Terminal Voltage.

∆ Vcent = | (1 - Ach value) - (1 - Bch value) |

This value is the voltage difference of 1ch.
