Kurzweil K2000, K2000R Manuals

Block B of Bank 1 is currently being tested. This minimizes distortion of the signal and crosstalk. Saving Dependent Objects The K should restart just as if a soft reset had occurred. Be careful not to damage the traces on the board. A 75 watt transformer is sufficient for the K K” figure displayed in the center of the status bar corresponds to the total amount of sample RAM installed in the unit.

Pin 1 is on the end of the IC which has the indentation in the middle. If the layer is panned all the way to the left or right, the separate outputs function as individual monophonic outputs with respect to that layer. Carefully lift the bottom half and place in a safe location until reassembly.

Kurzweil K2000, K2000R Service Manual

A type of distortion which occurs in digitally sampled sounds when higher pitches increased sample playback rates introduce partials that were not present in the original sound. Changing the voltage selector may require the use of a different power supply cord or attachment plug, or both.

Srcsong source Song This product must be grounded. Listen for proper output. Each K program can l2000r up to three layers – except drum channel programs, which can contain up to 32 layers.


Ground for the digital section is connected to digital ground. Each filter is two cascaded 3-pole Butterworth sections identical to kk2000r input filter described elsewhere.

The test results are displayed as shown in Figure 4. Ignore any reference to keyboard because the KR is not so equipped.

Kurzweil Music Systems – K – Owners Manual

Ql is an emitter-follower which minimizes current drawn from the M The oscillations in voltage are analogous to the waveforms of the lurzweil they generate.

Common Parameters For Track Functions The product should be connected to a power supply only of the type described in the operating instructions or as marked on the product. If a button is pressed, the appropriate row is pulled low and sensed by the M The 4 rows are held high by pull-up resistors in RP9 E Intonation Table Editor The K uses 31 sound-shaping algorithms to provide a variety of resonant filters, EQs, continuous panning, amplitude modulation, crossfade, distortion, digital wrap, waveshaper, pulse width modulation, high frequency enhancement, low maanual oscillators, hard sync oscillators and mixing oscillators, all with real-time MIDI control.

Instructions for setting the voltage selector are included manuap Section 2.

A total dynamic range of over lOOdB is available at these outputs. If the isplay indicates “Data Fail,” the read and write operations are normal, but the read signal and the “write” signal do not match. When the Sound RAM test is run, the display will indicate which block in which bank is currently being tested. It is a which has an enhanced core with bytes of RAM, one serial port, and two parallel ports built-in.

SCSI test will always fail without internal or external drive installed. Refer to figure 5. Pressing any button on the front panel or turning the Alpha Wheel one click to the right will generate the next-highest frequency. After recognition, the microprocessor resets the flip-flop.


Open the unit as described in Section 3.

Figure 7 below shows a timing diagram for one sample period. The test takes approximately 20 aecondg for each Megabyte of RAM. R provides a minimum load if the power supply is ever operated with no other components on the board.

The options are “1 Burn-in Test”, or “2 Test Forever. Check that the Volume slider is at least partially up from it’s bottom position. User Callable Diagnostics Refer to paragraph 4. The “five- step sampling option test” checks the integrity of the sampling option board and its connections to the CPU.

R81 suppresses possible emitter-follower oscillations. The mute circuit s must also be asserted when there is insufficient voltage. When a cable is plugged into the left MIX output alone, both the left AND the right audio signals are routed to the jack. This board can be easily damaged by careless handling. Many of the effects devices available today use digital signal processing techniques. If the observed address does not match the expected address, the test fails. Loosen the Phillips screw 2 turns.

AC line cord not fully inserted into outlet or unit.

Offering all of the same great sounds, power and features as the keyboard version. For the absolute maximum signal quality, the individual outputs should be used.
