GENERAL DESCRIPTION
(continued)
D•2500 features an advanced 32-bit point floating processor
DSP interface and high quality converters with 24-bit audio
resolution and sample rates up to 96kHz for pristine audio
quality. You can even upgrade your D•Class units to premium
Analog-to-Digital and Digital-to-Analog I/O (Input/Output)
converter boards, keeping your D•Class system up to date
with the best technology and sound, far into the future.
The D•2500 is perfectly at home in the studio or on the
road. The fact is, you would use the D•2500 equalizer for its
precise filtering and superb audio quality alone, but you get
the power of all the features, and then some, expected from
a high quality digital equalizer. Whether you are a recording
or a live sound engineer you’ll get a better sound using the
D•2500 Digital Equalizer!

FEATURES
>
The D•2500 is a stereo or two channel digital equalizer
with each channel providing 31 bands of equalization,
each frequency band representing 1/3 of an octave, on ISO
standards, in the 20 Hz to 20 kHz range.

The front panel provides 32 analog 45mm LED faders for
instant filter adjustment and true analog feel.
>
Custom Liquid Crystal Display is easy to read and provid es
critical paramter information.
>
Advanced 32 bit floating point DSP with high-end, 24 Bit
96K sample rate Analog-to-Digital and Digital-to Analog
converters provides a pristine sound quality with low
distortion and wide dynamic range.

Variable Q Filters with programmable bandwidth (1/4,
1/3 and 1/2 octave) ensures that the filter of the selected
frequency area stays the same even when approaching
maximum boost or attenuation. Plus, Auto Bandwidth
allows individual filters to have different filter cues. As a
result, the frequency response of the D•2500 will as close
as possible to your faders settings.

An onboard programmable Delay is included for time
aligning speakers.

The D•2500 offers programmable High and Low Pass Filters
for setting contour curves or for removing low-end stage rumble.

To help keep the over all system noise level low, the
D•2500 includes a programmable Noise Gate with variable
threshold control.

The programmable Enhancer can be used to add extra highs
or as a noise reduction system by lowering the high frequency
bands when no high end content is present.

ARCHITECT’S & ENGINEER’S SPECIFICATIONS
The D•2500 shall be a stereo 31 band digital graphic equalizer
for the purpose of equalizing an audio system. It shall have 31
faders to adjust the levels of the 31 bands of audio. The D•2500
shall also have automatic feedback reduction filters, gate, delay,
enhancer, HP/LP filters and a limiter for the purpose of equalizing
and balancing an audio system. The D•2500 shall have balanced
XLR inputs and outputs. The inputs and outputs shall be on
cards so that they can be removed and upgraded. A slot shall also
be provided for a D•Net card so that the unit can communicate
with other D•Class units at a faster speed than from the included
midi connections. There shall be 99 digital memory locations to
store and recall user program information. The D•2500 is one
of a series of 3 digital processors that can operate separately or
together as a single piece of analyzing equipment.
