the small timing glitches that would otherwise occur when switching the process in and out. Up to 99 presets can be stored and changed using a MIDI program change command.

Display: The SPECTRALIZER is equipped with two PPM-meters that feature high resolution in the important region immedia- tely before 0dB. Clip-LEDs indicate digital clipping, while the first LED of each PPM-meter functions as a signal present indicator to confirm that a digital signal is present at the input.

The philosophy behind the digital audio processors is that they are designed to be operated like analogue units; there is only one INFO menu but no multi-function controls. The LCD readout simply shows the current encoder positions and the preset number. The encoders are built without clicks or detents, so they feel like analogue pots. Our DSP platform uses two Motorola 56002 DSPs running at 66MHz. This enormous computational power guarantees real-time operation where sophisticated DSP algorithms will not be restricted by resource limitations. The general concept is that each digital processor should fulfill only one task, in the most effective way possible, and with a minimum of controls and switches. As much as possible should be automated to promote user-friendly opera- tion – the external controls access only the sonically relevant parameters. Additionally all controls with a wide value range (e.g. 0 to 100) are programmed with an 'alpha-dial' logic. Turning the encoder rapidly causes the values to jump in steps of 10, whereas turning the encoder slowly causes the values to proceed in single increment steps.

The housing of the SPECTRALIZER has the standard 19"- EIA format and occupies 1U (44 mm) in your rack. When installing the unit in a 19"-rack, the rear side of the unit needs some support, especially in a touring case.

The SPECTRALIZER should not be installed near units which produce strong magnetic fields or extreme heat. Do not install theSPECTRALIZER directly above or below power amplifiers.

Check that the voltage details quoted on the back panel are the same as your local mains electricity supply. Use a minus (-) screwdriver to set the voltage selector to the voltage for the area in which the unit will be used.

Never cover up the ventilation slots on the top of the unit. If, during operation, the sound is interrupted or indicators no longer illuminate, or if abnormal odor or smoke is detected, or if liquids are spilled on the unit, immediately disconnect the power cord plug and contact your dealer.

Only clean your SPECTRALIZER with a soft, lint-free cloth.
