3) AUTO/MAN switch (CH1) ........................................... MAN
4) AUTO/MAN switch (CH2) ........................................... MAN
Checking method:
1) Input 1 kHz, –50 dBu signal in the XLR terminal (INPUT1,
2).
2) Press the STATUS CHECK button to display the Audio Infor-
mation screen.
3) Rotating the CH1 AUDIO LEVEL control, check that Lch
waveform level of A/V Remote Connector varies.

waveform level of A/V Remote Connector varies.
Note 2: Along with the waveform check with the oscilloscope,
check that the level meter on the STATUS CHECK screen
varies.
