MAINTENANCE ALIGNMENT PROCEDURE

M-DAC-Ageing Test Step-P1/2

MDAC Soak Test procedure Rev 0.1

1. Insure that Mains input voltage is set to +/- 5% of rated input voltage.

2. Lock to an External SPDIF source Play Music file / source.

3. Insure Display, Knob and Buttons function correctly.

4. Confirm R/C function.

5. Insure audio is replayed correctly (Headphones can be used).

6. Soak test for > 8Hours.

7. Insure Display and Buttons function correctly.

8. Insure audio is replayed correctly (Headphones can be used).

9. Inspect internals of Unit for Blown Electrolytic capacitors Blown SMD Components etc.

Post Soak test performance verification

1. Set to COAX1, (Set Digital Generator on AP to 44.1KHz, 24 Bit, Dither, 997Hz, 0dB).

2. Check Unit is “Locked” and indicates 44.1kHz Freq. (As indicated on Display).

3. Check L & R SE Audio Outputs, Level 2.1V RMS (+/- 0.1dB).

4. Check L & R SE Audio THD, 0.0025% Max (Norm 0.001%).

5. Set AP to 997Hz -60dB, check L&R SE, SNR >54dB (=>114dB).

6. Set AP to -120dB 997Hz, Check L&R SE outputs, DC Level <= +/-5mV.

7. Set Digital Generator on AP to 44.1KHz, 24 Bit, Dither, 997Hz, 0dB.

8. Check L & R Balanced Audio Outputs, Level 4.2V RMS (+/- 0.1dB).

9. Check L & R Balanced Audio Outputs THD, 0.001% Max (Norm 0.0006%).

10. Set AP to 997Hz -60dB, check L&R Balanced, SNR >58dB (=>118dB).

11. Set AP to 44.1KHz, 24 Bit, Dither, 997Hz, 0dB.

12. Confirm COAX2, Optical 1&2 function (Locked indicated on display & Audio Signal
output).

13. Confirm USB function, replay Stereo 997Hz 0dB on PC media player, confirm SE Level

2.1V RMS (+/- 0.1dB), Audio THD, 0.0025% Max (Norm 0.001%).

14. Confirm R/C function.

MAINTENANCE ALIGNMENT PROCEDURE

M-DAC-Ageing Test Step-P2/2

15. Test Optical and BNC Digital CD Output function (with AP or external DAC), Digital

Output greater then =>500mV Pk-Pk into 75 Ohms.

16. Completion of Post Soak Test performance verification.

Listening Test

1. Connect to audio System (via RCA's), Lock to external SPDIF or USB Source,
confirm no undue noise function OK.

2. Test all Digital inputs (Coax1, 2, Optical1&2)andUSB(WithPC) repeat listening
test.

3. Confirm Remote function.

4. Completion of Listening tests.

Shipping Settings

1. Restore unit to Factory defaults.

2. End of Shipping settings.
