Spectralizer
Operation Safety
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 I
NFO 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 S
PECTRALIZER 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 S
PECTRALIZER should not be installed near units which
produce strong magnetic fields or extreme heat. Do not install
theS
PECTRALIZER 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 S
PECTRALIZER with a soft, lint-free cloth.
