The test is a single checksum procedure for each pair of Sound ROM chips.

Kurzweil K2000, K2000R Service Manual

Intonation Table Editor If the wheel is pulled forward, the ntimbers should decrease toward 1 or 0, again in steps of 2 or more. Fresh batteries should read in the range of 4. When a cable is plugged into right MIX output alone, only the right channel audio signal is heard.

Manjal not attempt to service the product beyond that described in the user maintenance instructions. R pulls the pedal voltage input to zero when there is no plug in J The Effects Section could be removed with little or no effect on the remaining j2000r. This will route the other instrument’s output to the K Shortcuts When Loading Objects In a successful test, the eight LEDs to the left of the LCD will flash in sequence from top left to bottom left to top right to bottom right at ms intervals.

These blocks, A-D, represent internal divisions of the address space; and do not correspond to any physical division of the sample RAM. As seen, the diagnostic program can also be used to check out the built-in panel and performance controls of the K Proper timing writes into the microcode RAM are critical and are synchronized with microprocessor operation by several signals and circuits.


The K should restart just as if a soft reset had occurred. Using a 2 Phillips screwdriver, remove the 16 sheet mnaual screws securing the keyboard to the bottom of its enclosure. Saving Dependent Objects The Burn-in test will hang up at the floppy drive test if you begin it without a disk in the drive.

U50 cannot kurzweio settling time for smooth transition between new data being presented to U16 and the output analog switch closures to begin passing the converted voltage to the output.

Simply put, when the output of U62 is within 1. The Transposition parameter on the Program mode page, manuual example, has a default value of 0. The fourth line represented by XXXX is generally the one of interest.

Based on that result, U50 sends out another trial value. Refer to figure 5.

D17 ensures gradual application of full voltage to the RAMs during power-up. It also checks for errors in the pin connections of each of these chips.

For testing in unrestricted free air, just the rear panel is acceptable as a “short-term” heatsink although it will get hot to the touch. Sampling Digital Signals There are twelve semitones to an octave. Sample Loop Playback Also check to see if amplifier, mixer, or speaker wiring is correct. The product does not appear to be operating normally or exhibits a marked change in performance; or E. Loading Individual Objects Filter – Digital Filters.

Volume slider has no effect.

Any sections not specifically identified with the K or the KR apply to both units. If the observed address the address read from matches the expected address the address wrxtten tothe test passes. This test is only necessary when the sampling option has been installed. Product features and specifications are subject to change without notice. Playback Mode playback Depending on the program you’re working with, you’ll have several different options for panning.


This provides automatic mono output through the Left output jac c when no Right channel cable is used. Alternatively, it is permissible to the power cable plugged in and the power on while changing the batteries, in which case memory will be retained as long as power is on. Blose the unit as per the instructions in Section 3.

When U9 is set for unity gain, its output current will be the same as its input current, namely uA. Under virtually all normal conditions an audio signal carries substantially less energy at high frequencies than at low frequencies, thus making this nearly impossible.

After conversion to sampled analog voltages at U and U D-6 to D-7the effected audio signals are filtered by circuitry around U7 F-6 to G In the unlikely event of a failure, the engine board must be replaced, since the Sound ROM chips are soldered in place.

Although the U38 and U40 circuits are low-pass filters with a cutoff of about 25KHz, their “Q” is high which gives a boost to the frequencies just below cutoff. Its effect on each note will be completely in phase, regardless how many notes are being played. The ends of ribbon cable wires touching the conductive coating inside the top cover can also cause improper operation.

Finally, magnetic fields can be a source of interference. This is done with the Contrast parameter in Master mode. Maximizing Music and Minimizing Noise Refer to paragraph 4. New Triggering Methods Pressing Open On Directories
