Testing Each of the Kurzweil 1000 Series Products

The following is a description on how to test each Kurzweil 1000 Series unit in order to determine whether or not it is functioning properly:

2.1 -1000 PX, HX, SX and GX Tests

Proceed with the following steps in order to test the 1000 PX, HX, SX and GX:

1. Connect a MIDI cable from MIDI In to MIDI Out on the rear panel of the 1000.

2. Connect a dB Meter/Distortion Analyzer to the Left Audio Output on the rear panel of the 1000. Turn the volume control on the front panel clockwise all the way to maximum volume. Please make sure the meters are accurate and have at least a 90 dB range. If this is not the case, the measurements made may not agree with the numbers listed below. The recommended device for testing the 1000 is the Tektronix AA501 Distortion Analyzer/AC Voltmeter. Note: Step 2 is only used for the Sine Wave Test.

3. Turn the unit off. Caution: high volume levels are present during many of the diagnostic tests.

4. Press the Program/Parameter Up and the Program /Parameter Down buttons at the same time, while turning the unit on. Keep both buttons depressed until the message: "KURZWEIL 1 000 TEST SUPERVISOR" is displayed on the front panel.

5. After two seconds the display should read:

"XTEST MAIN MENU >RUN ALL TESTS"

Push the Yes button once.

6. The display should now read:

"NUMBER OF PASSES >001."

The user now has the choice of how many times this battery of tests should be run. To run all tests once, push Yes.

7. The tests will start running now. The first test is the " L C D VISUAL TEST ." This test sends a stream of ASCII characters to the front panel display. Check to make sure that the upper and lower case alphabet and the numbers 0-9 are displayed properly on the front panel LCD. If these characters appear normal, the test has passed.

8. The next test is the "BUTTON TEST" In this test, the top line of the LCD displays the words "BUTTON TEST ," while the bottom line of the displays the identity of each button pushed. Push each button on the front panel and make sure that the

words displayed on the bottom line of the LCD match the names for these buttons on the front panel. Hold the buttons down long enough so that the name displayed on the LCD can be read. Pushing the No button twice will stop this test and allow the next test to be run.

9. After the button test has run, many test names should flash quickly on the top line of the LCD, followed by a pause on "RAM TEST" and "SOUND ROM TEST ." If no errors occur, the next display on the front panel will be:

"SINE WAVE TEST STEP001 1000Hz"

This is the calibration tone to measure frequency response in the 1000. Make sure the volume control on the front panel is turned clockwise all the way to maximum volume. One should now calibrate the dB meter connected to the left Audio Output of the 1000 to 0 dB. When this is completed, push any button on the front panel.

10. The bottom line of the front panel display should now read:

"STEP002 20Hz."

11. The bottom line of the front panel display should now read:

"STEP003 1 00 Hz."

This signal should read 0.0 dB, ::I: 0.5 dB on the dB meter. If this is not the case, this step of the Sine Wave test has failed. To go on to the next step, push any button on the front panel.

12. The bottom line of the front panel display should now read:

"STEP004 400Hz."

16. The bottom line of the front panel display should now read:

"STEP00S 16710Hz." For PX

"STEP00S 20000Hz." For HX, SX and GX

This signal should read between -60 and -99 dB on the dB meter. If this is not the case, this step of the Sine Wave test has failed. To go on to the next step, push any button on the front panel.

17. The bottom line of the front panel display should now read:

"STEP009 391 Hz."

This is the first of two distortion tests. The sine wave produced in this step should measure .33% Total Harmonic Distortion + Noise, or less. If this is not the case, this step of the Sine Wave test has failed. Make sure the distortion analyzer used is accurate, and the input is isolated from earth ground. To go on to the next step, push any button on the front panel.

18. The bottom line of the front panel display should now read:

"STEP010 391 Hz."

The sine wave produced in this step should measure .033% Total Harmonic Distortion + Noise, or less. If this is not the case, this step of the Sine Wave test has failed. Measure the AC RMS Voltage of this sine wave. It should be between 1.2 and 1.4 volts. If this is not the case this step of the Sine Wave test has failed. Set the dB meter to 0 dB using this sine wave as a reference. To go on to the next step, push any button on the front panel.

19. The bottom line of the front panel display should now read:

"STEP011 391 Hz."

The sine wave has been shut off. The output should now measure between -82 and -99 dB on the dB meter. If this is not the case, this step of the Sine Wave test has failed. Please make sure the meter is accurate and has at least a 90+ dB range. To go on, push any button on the front panel.

20. If the tests completed with success, the LCD Display should now read:

"Passes>00001 ERRORs>00000."

21. Now connect the dB Meter / Distortion Analyzer to the Right Audio Output of the 1000 on the rear panel. Push the Menu Up button five times until the bottom line of the display reads

">RUN SINE WAVE T."

Push the Yes button. The display should now read:

"NUMBER OF PASSES >001."

Push the Yes button. The display should now read:

"SINE WAVE TEST STEPO01 1000Hz."

Repeat the Sine Wave Test for the Right channel exactly as for the Left in lines 9 through 19 above.

22. Turn the unit off and wait 1 minute.

23. Next, turn the unit on, holding down the program UP and DOWN buttons used to enter the diagnostics.

PLEASE MAKE SURE THAT THE UNIT DOES NOT COME UP INTO PLAY MODE!

If the unit comes up into it's normal mode, one must re-run the previous tests, or run the RAM Test from the Test Select Menu to place the proper pattern back in the RAM. Push the Menu Up button six times until the display reads:

">RUN BATTERY TEST"

push Yes. When the LCD display responds with

"NUMBER OF PASSES >001,"

push Yes. If the unit responds with the display

2.8- SINE WAVE TESTS (PX, PX Plus, EX, K1000, EGP and MARK III)

The 1000 PX, EX, K1000, and EGP all have the same Audio Channel Output Frequency. Therefore, these units use the same Sine Wave Frequencies in order to test their Audio Channels. The eleven steps of the Sine Wave Tests for these Units, and there Pass/Fail Criterion follows below. The expected readings for Amplitude, Distortion, and the tolerance for each is in parenthesis.

Step# frequency (criterion)

Frequency response tests

1. 1000 Hz 0 dB reference (set dB meter to 0 dB)

2. 20 Hz (-2.0 dB ± .5 dB)

3. 100 Hz (0 dB ± .5 dB)

4. 400 Hz (0 dB ± .5 dB)

5. 4000 Hz (+ .4 dB ± .5 dB)

6. 10000 Hz (0 dB ± .5 dB)

7. 14500 Hz (-60 dB, + 0, - ∞ dB)

8. 16710 Hz (-60 dB, + 0, - ∞ dB)

Distortion tests

9. 391 Hz, max amplitude -40 dB (0.33%, + 0, - ∞ %) Test for 5 seconds min.

10. 391 Hz, max amplitude (0.033%, + 0, - ∞ %)

Dynamic Range test

11. 391 Hz, All channels off (-82dB,+ 0, - ∞ dB). Test for 5 seconds min.

It. should be noted that the Total Dynamic Range of the unit is not the > 82dB listed here. This test uses only one of 24/20 available channels.

2.9 -SINE WAVE TESTS (HX, SX AND GX)

The 1000HX, SX, and GX all have the same Audio Channel Output Frequency. These units therefore use the same Sine Wave Frequencies in order to test their Audio Channels. The eleven steps of the Sine Wave Tests for these Units, and their Pass/Fail Criterion follows below. The expected readings for Amplitude, Distortion, and the tolerance for each, is in parenthesis.

Step# frequency (criterion)

Frequency response tests

1. 1000 Hz 0 dB reference (set dB meter to 0 dB)

2. 20 Hz (-2.0 dB, ± .5 dB)

3. 100 Hz (0 dB, ± .5 dB)

4. 400 Hz (0 dB, ± .5 dB)

5. 4000 Hz (+ .4 dB, ± .5 dB)

6. 10000 Hz (0 dB, ± .5 dB)

7. 17000 Hz (-60 dB, + 0, - ∞ dB)

8. 20000 Hz (-60 dB, + 0, - ∞ dB)

Distortion tests

9. 391 Hz, max amplitude -40 dB (0.33%, + 0, - ∞ %). Test for 5 seconds min.

10. 391 Hz, max amplitude (0.033%, + 0, - ∞ %) Dynamic Range test

11. 391 Hz, All channels off (-82 dB, + 0, - ∞ dB). Test for 5 seconds min.

It should be noted that the Total Dynamic Range of the unit is not the > 82dB listed here. This test uses only one of 24/20 available channels.
