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.

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:

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.
