ULTRAMIX SELF TEST PROCEDURE
Setup:
Connect the MIDI OUT jack of the DUT to the MIDI IN jack of the DUT.
Use Control Interface Port test adapter to connect the TX to the RX signal at the CIP1.
RAM Test: (Tests SRAM and EEPROM)RAM Test: (Tests SRAM and EEPROM)
Action: Response:
Apply power to DUT.
2
PASS:PASS: The three LEDs on the front panel will light up sequentially
(MIDI first, then Bypass, then Local). All LEDs will then go off and
the Bypass LED will come back on, indicating that the DUT is in its
default power-on mode and is ready for normal operation.
FAIL: FAIL: The bottom two LEDs (Bypass and Local Mode) will flash
quickly and the DUT will hold in this failure mode.
IO Port Test: (Tests MIDI IO and Control Interface Port IO)IO Port Test: (Tests MIDI IO and Control Interface Port IO)
Action: Response:
Simultaneously apply power to DUT and
depress Local Mode switch.
3
Switch Test: ( Tests the front panel switches )Switch Test: ( Tests the front panel switches )
Action: Response:
This is a continuation of the IO Port Test.
Depress each switch, one switch at a time.
PASS:PASS: All three front panel LEDs should flash at about 4 Hz.
4
FAIL: FAIL: One (or more) of the LEDs remain unlit.
Bottom (Local Mode) LED = CIP failure
Middle (Bypass) LED = MIDI port failure
When a switch is depressed, its companion LED will go off as long
as the switch is engaged. Release the switch and the LED should
resume flashing.

If DUT is already powered up, remove power then reapply power.

The LEDs will not be flashing in sync, but that’s ok.

VCA / DAC and Meter Test:VCA / DAC and Meter Test:
( Tests the voltage controlled amps. , their digital to analog converters and the meter circuitry)( Tests the voltage controlled amps. , their digital to analog converters and the meter circuitry)
Action: Response:
This is a continuation of the IO Port Test.
Simultaneously depress the Local Mode and
Bypass switches.
Action: Response:
This is a continuation of the VCA / DAC and
Meter Test.
Simultaneously depress the Local Mode and
Bypass switches.
This test ramps all of the VCAs up and down and runs the
meter multiplexer.
The local mode and bypass LEDs indicate the direction that
the VCAs are being ramped, with the Bypass LED indicating an
upward ramp and the Local Mode LED indicating a downward
ramp. The VCAs can be held at full gain by depressing the Bypass
switch or at full attenuation by depressing the Local Mode switch.
The VCAs will return to ramp mode when the switch is disengaged.
This test will also allow you to check the meter circuitry by
probing pin 3 of any 4051 IC on the VCA board. As long as the VCA
test is active, the meter multiplexer is running.
End of Test:End of Test:
(Good Bye)(Good Bye)
Ends test and returns DUT to its normal operating mode.
