D 2500

SERIES	DESCRIPTION
D•CLASS	DIGITAL EQUALIZER

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.

CATEGORY

DIGITAL SIGNAL PROCESSING

>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.

>An added layer of speaker protection is accomplished by using the D•2500’s programmable brick wall Limiter.

>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.

>Equalization curves plus all digital effects can be stored or recalled using the 99 Preset Locations.

>Configure larger systems using multiple D•Class units which communicate over standard MIDI, or with Samson’s optional high-speed D•Net interface card.

>Electronically balanced XLR inputs and outputs.

>Internal power supply ensures reliability and trouble-free operation.

>Standard 19”, 2 rack-space design for easy integration into any traveling or fixed installation audio system.

>Aluminum extruded front panel and steel chassis makes the D•2500 eminently road-worthy.

>Three year extended warranty.

> 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.

> Automated Feedback recognition, indication and suppression

(Manual or Auto mode) with Automated Filter Restoration.

> The D•2500’s fader can be set for either 3, 6 or 12 dB of

gain and attenuation for each of the frequency bands.

> An onboard programmable Delay is included for time

aligning speakers.

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.
