l THERMAL TEST

1. Set input frequency to 1 KHz and short both channels while they are producing power into a load.

2. AC line current draw should be about 7.0 - 8.0 amps for both channels. As the amplifier gets hot, there will be some current drift upwards. This is not a problem as long as the case

temperature on the output transistors does not exceed 105 degrees

3.

Verify that the PTC circuit causes thermal shutdown after an extended period of time.

2. Remove the input signal connector from the amplifier and measure the residual noise level produced into the load by the amplifier. The noise signal should be 100 dB down from the

full output power point measured. A signal to noise ratio should be better than or equal to

100dB.

Check both channels.

2. With an input amplitude of

increase the input frequency to 20kHz. Reduce the input

signal 20dB (80%) from full output. At this point, a couple of watts of output power should be

observed at the output.For the first channel to be calibrated, adjust the crossover

so that the total distortion for that channel is at about 0.1% THD+N. If bias is not settable, see the bias description and troubleshooting section of this manual.

3. If a distortion analyzer is not available, a less accurate crossover distortion and bias adjustment can be made by monitoring the driver transistor

input signal to both channels of the

amplifier. Ensure that power is on and that the gain controls are fully up.

2. While the amplifier is producing power into the loads, apply a short to the output binding posts of each channel. In other words, apply a jumper between the red and black binding posts of each channel. Once this is done, the combined AC line current draw for both channels should be no greater than

8.0A

ac. This is with a

120VAC

service. Current may be lower as AC line voltage is lower. As the amplifier heats up, current draw may increase to about 9A until thermal protect shutdown.

3.

While the amplifier is driving a short, observe the main supply rail voltages. Ideally, they will be

no more than 3 volts from each other.

4. Remove the short from each channel and verify that the channels recover in to 4 ohm loads. The output should not experience any hang up and a full

sinewave

it was before a short was applied for this test.

and power supply problems)

-

Current limiting wrong

l Current limiting too high into a short

. IC rail too high into a short

-

Current limiting too low into a short

l Uneven voltage rails

Current limits should remain high down to 2 ohms, and collapse to a lower value for short circuits. This is caused by the IC rails going from normal 14 - 1.5 volts to about 5-6 volts. Current limit trimmers

TR502 & TR503

permits adjustment of each channel to a specified range.
