TEST PROCEDURES
Required Items:
• Audio Signal Generator
• dB Meter
• Audio Precision AUX-0025 digital filter
• 2 - 4 Ohm, 300W load resistors
• 2 - 16 Ohm, 300W load resistors
• 2 - 32 Ohm, 300W load resistors
Test Setup:
- Connect the amplifier to the loads and test
equipment as shown in Test Connections.
- Set the PS602P rear panel controls as
listed below for following tests.
Set the front and rear panel controls as listed
below for following tests.
• Front Panel Output 1 and 2 Level Controls
set to Max (fully CW)
• Rotary EQ switch to position 1 FLAT
• Output Attenuation to MAX (fully CW)
• DIP switch setting: all switches to LEFT
Note: The AP AUX-0025 filter must be used
for all measurements.
1. Gain Test - Low-Z Mode
1.1 Set the Output 1 and 2 DIP switches to
Low-Z mode (right).
1.2 Connect 4 Ohm, 300 W loads to the
channel 1 and 2 outputs.
1.3 Apply a 1 kHz, -19.3 dBV input to the
channel 1 and 2 RCA input jacks.
1.4 Measure the output level at the channel 1
and 2 output jacks. It should be +25 dBV
+/- 1 dBV.
2. Gain Test - Hi-Z 70V Mode
2.1 Set the Output 1 and 2 DIP switches to
Hi-Z mode (left).
2.2 Connect 16 Ohm, 300 W loads to the
channel 1 and 2 outputs.
2.3 Apply a 1 kHz, -19.3 dBV input to the
channel 1 and 2 RCA input jacks.
2.4 Measure the output level at the channel
1 and 2 output jacks. It should be +28 dBV
+/- 1 dBV.
3. Gain Test - Hi-Z 100V Mode
3.1 Set the Output 1 and 2 DIP switches to
Hi-Z mode (left). Set the GLOBAL OUT DIP
switch to 100V (right).
3.2 Connect 32 Ohm, 300 W loads to the
channel 1 and 2 outputs.
3.3 Apply a 1 kHz, -19.3 dBV input to the
channel 1 and 2 RCA input jacks.
3.4 Measure the output level at the channel
1 and 2 output jacks. It should be +31 dBV
+/- 1 dBV.
4. Gain Test - XLR Inputs
4.1 Set the Output 1 and 2 DIP switches to
Hi-Z mode (left). Set the GLOBAL OUT DIP
switch to 100V (right). Set the SENSITIVITY
DIP switch to 12 dBu (right).
4.2 Connect 32 Ohm, 300 W loads to the
channel 1 and 2 outputs.
4.3 Apply a 1 kHz, -19.3 dBV input to the
channel 1 and 2 XLR input jacks.
4.4 Measure the output level at the channel
1 and 2 output jacks. It should be +11 dBV
+/- 1 dBV.
4.5 Set the SENSITIVITY switch to 4 dBu.
