Procedure

1) Connect components as shown in Fig.1. (TEST = 0)

2) Set the encoder to MONO mode, and input 110mVrms (1kHz 100% modulation) to MPX IN (Pin 5).

3) Set the encoder to stereo mode, and input only left channel signal (1kHz 100% modulation) to MPX IN

(Pin 5).

4) Monitor the oscilloscope and AC voltmeter and adjust ATT so that the R-ch is at a minimum.

(Separation standard: more than 35dB)
