When it is in LINE IN R input, press the AUX1 key down and select the "PRE" output,
the AUX1 output is -6±2dB; push the LEVEL in channel to "+10", the output has no
variation; release the "PRE" key, the AUX1 output in 4±2dB.
After the test is OK, push the channel slide potentiometer to "0", and make the AUX1
output is 0dB, then rotate the AUX1 knob to min
"-∞".
(the same procedure to test
AUX2)
e. Rotate the AUX3 in tested channel to min, the AUX3 has no output;
f. Rotate the AUX3 knob in tested channel to "0",
When it is in the LINE IN L input, the AUX3 output is 2±2dB;
When it is in the LINE IN R input, the AUX3 output is -6±2dB.
g. Rotate the AUX3 in tested channel to "10",
When it is in the LINE IN L input, the AUX3 output is 10±2dB;
When it is in the LINE IN R input, the AUX3 output is 4±2dB.
After the test is OK, push the channel slide potentiometer to "0", then rotate the AUX3
knob to min "-
∞
" in counterclockwise.
(the same procedure to test AUX4)
