G1 Test Procedures (aCOMP)

Required Equipment

Audio Precision System 2 with APWin software

100 Mhz oscilloscope connected to APS2 Analyzer Signal Monitor outputs (Ch. A and Ch. B)

Connection Mode

Use Audio Precision System 2 analog unbalanced (BNC) inputs/outputs.

Test Procedures for AlphaComp

Amplitude response test

On PC:

-Load file: alfacomp_amplitude (APWin File menu / Open / Test )

Test Connections:

-Output A of Audio Precision System Two --> LEFT input of the device under test.

-LEFT output of the device under test --> A input of Audio Precision System Two

-RIGHT output of the device under test --> B input of Audio Precision System Two

On the Alphacomp:

-Turn on the power switch.

-Set INPUT volume to maximum.

-Set OUTPUT volume to maximum.

-Set PROGRAM to AGC PURE.

-Set VARIATION to 1.

Start the sweep (F9) and control the results (Page3 – Graph) in the following conditions:

-hardware bypass switch pressed.

-hardware bypass switch released.

THD test

On PC:

-Load file: alfacomp_THD (APWin File menu / Open / Test )

Test Connections:

-Output A of Audio Precision System Two --> LEFT input of the device under test.

On the Alphacomp:

-Turn on the power switch.

-Set INPUT volume to maximum.

-Set OUTPUT volume to maximum.

-Set PROGRAM to AGC PURE.

-Set VARIATION to 1.

Start the sweep (F9) and control the results (Page3 – Graph) in the following conditions:

-LEFT output of the device under test --> A input of Audio Precision System Two / hardware
bypass switch released.

-RIGHT output of the device under test --> B input of Audio Precision System Two /
hardware bypass switch released.

S/N test

On PC:

-Load file: alfacomp_SN (APWin File menu / Open / Test )

Test Connections:

-Output A of Audio Precision System Two --> LEFT input of the device under test.

On the Alphacomp:

-Turn on the power switch.

- With hardware bypass switch in COMP position and both outputs connected to the Audio
Precision, increase the INPUT level until the device`s outputs clip, and after reduce the INPUT
level itself until the outputs exit from clipping state.

-Set OUTPUT volume to maximum.

-Set PROGRAM to AGC PURE.

-Set VARIATION to 1.

Start the sweep (F9) and control the results (Page3 – Graph) in the following conditions:

-LEFT output of the device under test --> A input of Audio Precision System Two / hardware

bypass switch pressed.

-RIGHT output of the device under test --> B input of Audio Precision System Two /
hardware bypass switch pressed.

Stability test

On PC:

-Load file: alfacomp_stability (APWin File menu / Open / Test )

Test Connections:

-Output A of Audio Precision System Two --> LEFT input of the device under test.

-LEFT output of the device under test --> A input of Audio Precision System Two

Test:

Move the input level knob from 0 to maximum 3 times and control the output waveforms:
NO PERMANENT SINE WAVEFORMS should be visible. IF PERMANENT
WAVEFORMS WITH FREQUENCY > 20 kHz should become visible on whatever output
channel, THE UNIT IS TO BE INSPECTED.
