Setting Idle Current
The following is the instructions for setting Idle current:
Setting the idle current to the following ranges will require you
to measure the voltage across the indicated resistors and adjusting
the indicated variable resistors to set the required voltage range.
This adjustment is performed with no loads on the outputs with no
signal input.
Specification: 45
mA
± 5mA
Voltage Range:
4.0 mV to 5.0 mV
1. Measure voltage across Resistor R433 and set VR501 to Voltage Range.
2. Measure voltage across Resistor R434 and set VR502 to Voltage Range.
3. Measure voltage across Resistor R435 and set VR503 to Voltage Range.
4. Measure voltage across Resistor R436 and set VR504 to Voltage Range.
Notes:
The Idle current should be set when the amplifier has not been run for awhile,
and set at room temperature.
