Following the LCD display prompts, general knowledge will guide you through the tests. Keymaps usually contain numerous sample roots pitch-shifted across a range of several keys.

The sine wave at 20 Hz is generated as soon as the test is initiated. The first performs current-to-voltage conversion while the second reinverts the signal’s phase and applies one pole of the high frequency cut to cancel the lower boost pole added at the input mixer.

In the unlikely event of a failure, the engine board must be replaced, since the Sound ROM chips are soldered in place. Placing an oscilloscope probe at TPl will show a sampled version stair-step approximation of the input signal.

As a noun, the device which makes the switch. A reasonably good sine wave appears at J The aft row of screws have flat washers under them. Kugzweil assume for now that you’re using only the MIX outputs.

Using a 2 Phillips screwdriver, remove the six 6 machine screws securing the bottom half of the shell to the top – one in each corner and two near the center of the kanual. A-2 The resulting current flow ranging from 0 to about 1.

The Main Page Your dealer should have set the voltage switch to match the voltage in your area, but it is a good idea to check it. Memory tests check the physical memory addresses of the data corresponding to various components. This is not the same as “2X oversampling” because each pair of very slightly different words is derived from the same sample but it does significantly reduce distortion of very low level signals.

Each parameter has a range of available values, one of which you select while editing. Two or more SCSI devices – they can be computers, hard disks, printers, just about anything that sends or receives information in standardized form – are connected via special cables to their SCSI ports.

Selection By Dependents To install a key simply reverse 3. If sound is still not heard, a good suggestion would be to test the audio cables, replace them, or test for sound by connecting a high quality pair of headphones to the headphone jack. Inspect for proper installation – make sure the ICs are firmly seated into the sockets and that none of the pins of the ICs are bent.

Sampling Analog Signals Rocking the pedal forward should make the numbers increase toward while retiring it should make them decrease. Record A Bass Line SCSI individual test without drive: Any other problems such as distortion, disk errors, or lost data are cause by something other than line voltage fluctuations.

For additional assistance, k2000d the items in the following troubleshooting guide. Q1 is normally off when the M is actually sensing buttons in order to minimize the saturation voltage of U31 and give a good logic low level to sense. The fourth line represented by XXXX is generally the one of interest.


When the test is completed, the display will show the result of the test. Virtually all of the effects circuitry is licensed from DOD Digitech and is basically contained in the DSP stand-alone effects processor.

The output voltage can be adjusted to balance between brightness and the acoustic noise level from the panel by changing the value of R F Four flashes indicate both a low ,urzweil and an off-center Pitch Wheel. Cursong current Song Slide the fuse block back onto the Phillips head screw and pedestal. You will get the best signal-to-noise ratio if you keep the KR at full volume turn the volume knob fully clockwiseand adjust the level from your mixing board.

Pressing Open On Files The diagnostic software expects the data written to memory to be read back exactly as it was written. It is extremely important for the Engine board to know when there is sufficient voltage for proper operation so as to reset itself. If a switch pedal is plugged into the Switch Pedal 1 jack, the fourth line will show “PEDAL 1” when the pedal is closed, and will go blank when it opens.

As with th ch pedals should be unplugged y tested. To enter the diagnostic program, simply press the 4, 5, and 6 buttons simultaneously when in the Program Mode. Although quite different from the L-C filter described elsewhere, this circuit was selected to avoid alterina the desirable “DSP sound”.
