Operation Safety
Indications and Metering: The Loudness Maximizer is equipped
with PPM meters for input and output that show the signal level
with maximum resolution (0.01dB) just before 0dB.
The Signal LED is the first LED in each PPM meter that lights up
when a digital source is present at the inputs
The Possible LED chain represents the first device to show how
much subjective loudness can be gained. Initial settings for the
DESIRED GAIN control are shown here.
The Done LED chain indicates the percentage of achieved gain
change. It shows how much of the Desired gain setting was
actually realized.
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 auto-
mated to promote user-friendly operation – 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 Loudness Maximizer 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 Loudness Maximizer
should not be installed near units which produce strong
magnetic fields or extreme heat. Do not install the Loudness
Maximizer 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 Loudness Maximizer with a soft,lint-free cloth.
