1. Testing the power supply
Plug the external power supply into the AC line voltage source, but do not plug the power supply into the
DM8 yet.
Use an AC volt meter and measure the AC voltage on the power supply output plug. It should be 9VAC to
12VAC.
If the voltage is too high, it may damage the DM8 unit. Do not plug it into the DM8.Locate and correct the
problem with the power supply or the AC Line voltage before continuing with the test.
After verifying the AC power supply voltage is correct, plug it into the DM8 and continue with Step #2.
2. Entering Diagnostics Mode
While holding down [STOP] and [REC], turn on power. The unit will enter diagnostic mode. Note that a
restart is required to exit diagnostic mode.
After start-up is complete the LCD will display the first test. On the test selection page,
these buttons can be used to do the following:
[CURSOR UP] select previous test
[CURSOR DOWN] select next test [PLAY] run test
After a test finishes and displays either a pass or fail, the [STOP] button will exit the test to return to the test
selection page.

DM8 MP DIAGNOSTIC TEST PROCEDURE
DAC to Main Outputs
a) Connect both Main left and right outputs to the AP analyzer inputs. Because the Main left and right outputs
are cross-wired to support mono mix from either jack, both the left and right channels must have something
plugged in. Otherwise, the left and right signals ill simply be summed onto the output that is used, and this
will produce invalid AP measurements.
b) Turn Main level to maximum. Verify that the output level is approximately between 14.6Vpp to 17.8Vpp
(16.5dBu to 18.2dBu). Measure THD+N and verify that it is less than 0.007% (bandwidth set to 22-22KHz).
c) Press [CURSOR UP] to change output to “MainL” and verify that there is only signal from the Main left
jack. Press [CURSOR UP] once more to change the output to “MainR” and verify that only the Main right
jack is generating the tone.
d) Press [CURSOR UP] one more time to select “Off,” and verify that the SNR is at least 90dB, 95dB
A-weighted (22-22KHz bandwidth).
DAC to Headphones
a) Turn down the main level to minimum, then plug in a pair of headphones into the headphone jack.
b) Press [CURSOR DOWN] several times to select “All” again. Then slowly turn up the Main level to a
comfortable volume. Verify that the tone can be heard on both the left and right earpieces.
c) Press [CURSOR UP] once to select “MainL” and confirm that the tone is only audible from the left
earpiece. Press [CURSOR UP] once more to select “MainR” and confirm that the tone is only present on the
right earpiece.
Aux In to Main Outputs
a) Press [CURSOR UP] several times to select “Off.” Then turn Main level to minimum.
b) Connect the AP analyzer inputs back to the Main left and right outputs (again making sure that both Main
left and right outputs are connected).
c) Connect the AP generator outputs to the AUX IN 1/8” TRS jack. Set the AP generator to 8.1Vpp
(11.4dBu), 1KHz. Verify that the level from the Main left and right jacks is approximately 14.4Vpp to
17.8Vpp (16.5dBu to 18.2dBu), and that THD+N is less than 0.025% (22-22KHz BW).
d) Turn off the signal to Aux right input and verify that only the Main left output has a tone. Turn on the
signal to Aux right input on.
e) Turn off the signal to Aux left input and verify that only the Main right output has a tone.
f) Turn off the signal to both the Aux left and right input and verify that the SNR is at least 95dB,
100dBA-weighted (22-22KHz)

DM8 MP DIAGNOSTIC TEST PROCEDURE
Aux In to Headphone Outputs
a) Turn the Main level to minimum, and connect the Headphone output to the AP analyzer inputs. Set the AP
analyzer input impedance to 600 Ohms.
b) Connect the AP generator output to the AUX IN 1/8” TRS jack. Set the AP output to 2Vpp (-0.8dBu),
1KHz. Verify that the headphone left and right output levels are approximately between (14dBu to 16.8dBu).
THD+N should be less than 0.010% (22-22KHz BW).
c) Turn off the signal to Aux right input and verify that only the Headphone left output has a signal. Turn on
the signal to Aux right input.
d) Turn off the signal to Aux left input and verify that only the Headphone right output has a tone.
e) Turn off the signal to both the Aux left and right input and verify that the SNR for both Headphone left and
right outputs is at least 90dB, 95dB A-weighted (22-22KHz BW).

LCD will display the following briefly:
KICK CABLE
Test TIP
Level OK
Trig 0 = 305

DM8 MP DIAGNOSTIC TEST PROCEDURE
Note that the trigger level shown (displayed after “Trig 0 =”) will vary. There is no need to note the actual
level unless it fails.
All cables will have their TIPS tested. However, some cables will have additional tests the RING and/or
SWITCH inputs.
e) If the TIP passes and the cable being tested has a RING input, a screen similar to this will be shown:
PERC1 JACK
Test RING
Press S2 on the trigger tester to test the RING. As before, if the correct signal level is detected, the LCD will
display the following briefly:
PERC1 JACK
Test RING
Level OK
Trig 1 = 298
f) If the TIP or RING passes and the cable being tested has a SWITCH input, a screen similar to this will be
shown:
PERC1 JACK
Test SWITCH
Press S3 on the trigger tester to test the SWITCH. If a switch closure is detected, the LCD will display the
following briefly:
PERC1 JACK
Test SWITCH
Level OK
Trig 1 = 16383
g) At this point, if all the previous tests pass (TIP, and/or RING, and/or SWITCH), the LCD will display the
following.
PERC1 JACK
Jack OK
h) Plug a different DB25 cable into the trigger tester and repeat from step c until all 10 trigger inputs have
been tested (including PERC1 and PERC2 jacks). When all the cables/jacks have been tested (and all
passed) the LCD will display the following:
TRIGGERS
Passed

DM8 MP DIAGNOSTIC TEST PROCEDURE
ADDITIONAL NOTES:
1) During the tests, if the detected level is too high or too low, the LCD will display the
one of the following:
KICK CABLE
Test TIP
Level too high
Trig 1 = 405
OR
KICK CABLE
Test TIP
Level too low
Trig 1 = 120
The firmware also checks if the signal that is being detected is coming from the jack that
is currently being displayed on the LCD (in the example below, Jack 1). If a signal is detected
coming from a different input, the LCD will display the following:
KICK CABLE
Test TIP
Incorrect input
Trig 5 = 299
Pressing [STOP] will allow the user to skip the current test if it is not passing in order
to continue.
2) For any jack that fails, the LCD will display the following:
PERC1 JACK
Failed:TIP RING SW
Retry or test
another jack.
Only the item(s) that failed will be displayed. For example if the TIP and SWITCH failed,
the LCD will display the following:
PERC1 JACK
Failed:TIP SW
Retry or test
Another jack.
3) Because the input circuitry of the HIHAT cable has different hardware gain than all the
other inputs, the trigger level required to pass the test is different (~430 for HIHAT vs
~300 for all others).
