D2500 Features

The Samson D2500 Digital Graphic Equalizer utilizes state-of-the-art, DSP and filtering technology for precise tonal 

control. Here are some of its main features:

•   The D2500 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 D2500 will as 

close as possible to your faders settings.

•   Automated Feedback recognition, indication and suppression (Manual or Auto mode) with Automated Filter 

Restoration.

•   The D2500’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.

•   The D2500 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 D2500 includes a programmable Noise Gate with variable 

threshold control.

•      An added layer of speaker protection is accomplished by using the D2500’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 D2500 eminently road-worthy.

•  Three year extended warranty.
