6. TEST PROCEDURE

The Finished Products Test

- 5 -

1. Set the encoder to FLAT (encoder setting: 0000), INPUT/OUTPUT use 1/4 TRS BAL jack to co nnect
LCH IN, LCH/RCH OUT, plug in POWER&CLIP LED wires(semi product), the red POWER LED
lights up.

2. Input 1KHZ–6dBu(VP-7724 BAL) signal, then adjust INPUT GAIN VR, when INPUT GAIN VR is
minimum, the output is -20+/-2dbu, distortion<0.03%.

3. Adjust INPUT GAIN V R to maximum, the output i s +20+/-2dbu, distortio n<0.01 %( Please select the
corresponding filter when testing distortion).

4. Adjust INPUT GAIN VR, and set the output to +6.5~+8.5dbu, make sure the CLIP LED lights up
slightly.

5. Adjust INPUT GAIN VR, set the output to 0+/-0.2dbu, and also make sure the scale of GAIN VR at
0dB position.

6. According to the following table to test the frequency response, specifications are the following
(altogether 4*4=16 modes), under FLAT mode, make sure the distortion<0.005%.

7. Adjust the input signal to 1 kHz +10dbu, turn GAIN VR from minimum to maximum, make sure the
distortion will become bigger gradually till clipping (FLAT position).

8. Cut off input signal, when output noise and GAIN VR are minimum, the output noise is less

- 6 -

than-95dBu(Please select the corresponding filter), when the GAIN VR is maximum, the output
noise is less than -78dBu, at the same time, make sure the variations of the waveform are normal
when turning the GAIN VR.

9. Connect OUTPUT to RCH OUT, make su re the R CH output specification is the sam e as above, and

connect the INPUT to RCH IN; also the RCH output specification is the same as above.

10. Listening Test: Input music signal, set the encoder and adjust the GAIN VR, make sure the volume
can change, and also the treble and bass have corresponding variations; cut off the input signal,
make sure the noise sound is normal, set the encoder, make sure the CLICK NOISE is normal.

Second: Use AP to test

1. Set the encoder to FLAT (encoder setting: 0000), INPUT/OUTPUT, use 1/4 TRS Balanced jack to
connect LCH IN, LCH/RCH OUT, plug in POWER&CLIP LED wires(semi product), the red POWER
LED lights up.

2. Input signal is 1KHZ 0dBu (VP-7724 BAL), make sure INPUT GAIN VR is minimum, the output is

-20+/-2dbu, and distortion<0.03%.

3. Adjust INPUT GAIN VR to maximum, the output is +20+/-2dbu, the distortion<0.01 %( It must select
the corresponding filter when test the distortion).

4. Adjust INPUT GAIN VR, set the output to +6.5~+8.5dbu, make sure the CLIP LED lights up slightly at
the moment.

5. Adjust INPUT GAIN V R, set the output to 0+/-0.2dbu, at the same time, make sure the scale of GAIN

VR at 0dB position.

6. According to the following table to test the frequency response, specifications are the following
curves (altogether 4*4=16 modes). In the meantime, make sure the distortion<0.005% under the
FLAT mode.

7. Adjust the input signal to 1 kHz +10dbu, turn GAIN VR from minimum to maximum, and make sure

the distortion will become bigger gradually till clipping (FLAT position).

8. Cut off the input signal, make sure the output noise and GAIN VR are minimum, the output noise is
less than-95dBu (select the corresponding filters), when GAIN VR is maximum, the output noise is
less than -78dBu, at the same time, make sure the variations of the waveform are normal when
turning the GAIN VR.

9. Listening Test: Input music signal, set encoder and adjust the GAIN VR, make sure the volume can

change, and also the treble and bass have the corresponding variation, cut off input signal, make sure
the noise sound is normal, set the encoder, and also make sure the CLICK NOISE is normal.
