ADJUSTMENT AND CONFIRMATION PROCEDURES 2
3. Confirmation of Current detection circuit
Set the unit to "TEST-1-00".
Connect the differentiating circuit and apply the 200Hz square signal to DVD INPUT terminal
of each channel.
Adjust the attenuator or Volume so that the output level becomes 35V p-p.
Confirm that the speaker relay does not turn OFF when a 4.0 ohm load is connected.
Confirm that the speaker relay turn on when a 2.0 ohm load is connected.
Caution:Don't continue more than 3 seconds.
