DP428
The DP428 is XTA’s most advanced speaker management system. With 4x8 matrix flexibility and 48dB crossover slopes, sophisticated tools are close at hand. An array of filters types are available including parametric, shelving, bandpass, notch, and elliptical. Phase on all inputs and outputs is adjustable in 2 degree steps. AES/EBU inputs and outputs are built-in and easily selectable. Two stages of limiting insure safety further down the audio chain. 96kHz/24-bit internal processing is on board for pristine audio quality. The DP428 puts XTA’s transparent algorithms to work in a compact 1U package that remains easy to use.
The DP428 is a powerful DSP based audio processor, ideally suited for install applications, where it combines the functions of a multitude of conventional products in a compact 1U unit with extensive remote control capabilities. To achieve this, the DP428 has four inputs and eight outputs which can be configured in a selection of basic crossover modes – 4 x 2 way 2 x 3 way + 2 Aux 2 x 4 way and 1 x 8 way. It also offers a “free assign” mode, which allows completely flexible routing of any output from any combination of inputs.
Each input has a gain control, variable delay, a 28 band graphic equaliser and a further eight bands of fully parametric equalisation. The parametric filter bands have a large selection of different filter types available, including shelving, notch, band-pass, phase and elliptical behaviours.
Each output has a gain control, variable delay, high and low pass crossover filters, nine bands of fully parametric equalisation, polarity switching and, additionally, a fully featured limiter, and a final clip limiter. The crossover filters offer slopes of up to 48dB/Octave., with a variety of responses available.
The DP428 is also equipped with AES/EBU digital inputs and outputs, and includes a sample rate converter, capable of accepting anything from 32 kHz up to 192 kHz.
It may be controlled externally by XTA’s proprietary Windows software, along with existing and future ‘Audiocore’ products.
The DP428 features superb audio quality – carefully optimised double precision signal processing coupled with 24 bit conversion ensure a dynamic range in excess of 117dB. The high sampling rate of 96 kHz means minimal filtering providing exceptional sonic purity with a bandwidth in excess of 32 kHz.
A flexible 4-input/8-output multi-mode format caters for any configuration, regardless of scale.
Both routing of inputs to outputs, and ganging (for editing) are completely flexible.
A completely new SHARCTM based DSP platform supplies phenomenal computational power, allowing the unit to provide not only multiple bands of standard parametric equalisation on every input and output, but an additional full spectrum graphic equaliser on each of the four inputs. This additional power also permits both program limiters and no overshoot clip limiters on each output.
Delay of up to 650mS may be independently set for each output, with an exceptionally fine minimum increment of 300nS, which corresponds to a distance change of 0.1mm
The comprehensive standard specification also includes up to 255 memories, and remote control via MIDI, RS232 or RS485 ports, with security lockout.

Used XTA Electronics
XTA Electronics is a leading professional audio company based in the UK. We design and manufacture professional audio equipment used extensively around the world in both live touring and installed applications.From humblest beginnings in a spare room in Worcestershire, to the million pound facility of the present, the XTA story is far from ordinary.Have a read through our history and find out how it all began, with a mic splitter, right up to the present day with our range state of the art digital signal processing.
Andrew Grayland and John Austin former R&D manager and one of the Technical Directors of Klark Teknik started XTA in 1992. Having overseen many of the benchmark products produced by KT, both Andrew and John felt that DSP (digital signal processing) technology could find a home at the heart of PA systems.
At this time DSP was often disregarded because of its audio quality, but Andrew and John felt with the right algorithms and using 32-bit processing coefficients instead of 24-bit – what the majority of DSP designs were using – digital equipment could be designed that would sound very pure and clear.

Active: Powered. An active crossover is electrically powered and divides the line-level signal prior to amplification. An active speaker includes an active crossover and built-in amplifier.
Actuality: Audio from an announcer speaking.
Amplifier: A component that increases the gain or level of an audio signal.
Balanced Input: A connection with three conductors: two identical signal conductors that are 180 degrees out of phase with each other, and one ground. This type of connection is very resistant to line noise.
Bandpass: A two-part filter that cuts both higher and lower frequencies around a center band. A bandpass enclosure cuts high frequencies by acoustic cancellation and low frequencies by natural physical limitations on bass response.
Bandwidth: In audio, the range of frequencies a device operates within. In video, the range of frequencies passed from the input to the output. Bandwidth can also refer to the transmission capacity of an electronic communications device or system the speed of data transfer,is very important when planning a meeting for the attendees to stay connected.
Bass: Low frequencies those below approximately 200 Hz.
Bi-Wiring: A method of connecting an amplifier or receiver to a speaker in which separate wires are run between the amp and the woofer and the amp and the tweeter.
Boost: To increase, make louder or brighter opposite of attenuate.
Bridging: Combining two channels of an amplifier to make one channel that more powerful. One channel amplifies the positive portion of an audio signal and the other channel amplifies the negative portion, which are then combined at the output.
CD: Compact Disc. Ubiquitous digital audio format. Uses 16-bit/44.1-kHz sampling rate PCM digital signal to encode roughly 74 or 80 minutes of two- channel, full-range audio onto a 5-inch disc.
CD-R: Recordable Compact Disc.
CD-RW: Rewritable Compact Disc.
Channel: In components and systems, a channel is a separate signal path. A four-channel amplifier has at least four separate inputs and four separate outputs.
Coloration: Any change in the character of sound (such as an overemphasis on certain tones) that reduces naturalness.
Crossover: A component that divides an audio signal into two or more ranges by frequency, sending, for example, low frequencies to one output and high frequencies to another. An active crossover is powered and divides the line-level audio signal prior to amplification. A passive crossover uses no external power supply and may be used either at line level or, more commonly, at speaker level to divide the signal after amplification and send the low frequencies to the woofer and the high frequencies to the tweeter.
Crossover Frequency: The frequency at which an audio signal is divided. 80 Hz is a typical subwoofer crossover point and is the recommended crossover point in theatrical and home THX systems. Frequencies below 80 Hz are sent to the subwoofer signals above 80 Hz are sent to the main speakers.
Cut: To reduce, lower opposite of boost.
Decibel (dB): A logarithmic measurement unit that describes a sound`s relative loudness, though it can also be used to describe the relative difference between two power levels. A decibel is one tenth of a Bel. In sound, decibels generally measure a scale from 0 (the threshold of hearing) to 120-140 dB (the threshold of pain). A 3dB difference equates to a doubling of power. A 10dB difference is required to double the subjective volume. A 1dB difference over a broad frequency range is noticeable to most people, while a 0.2dB difference can affect the subjective impression of a sound.
Delay: The time difference between a sonic event and its perception at the listening position (sound traveling through space is delayed according to the distance it travels). People perceive spaciousness by the delay between the arrival of direct and reflected sound (larger spaces cause longer delays.
Diaphragm: The part of a dynamic loudspeaker attached to the voice coil that produces sound. It usually has the shape of a cone or dome.
Diffusion: In audio, the scattering of sound waves, reducing the sense of localization. In video, the scattering of light waves, reducing hot spotting, as in a diffusion screen.
Digital Audio Server: Essentially a hard drive, a digital audio server stores compressed audio files (like MP3 or WMA). Most include the processing to make the files, and all have the ability to play them back.
Direct-Stream Digital: A format for encoding high-resolution audio signals. It uses a 1-bit encoder with a sampling rate of 2,822,400 samples per second (verses 44,100 for CD). Used to encode six high-resolution channels on SACD.
Dispersion: The spread of sound over a wide area.
Distortion: Any undesired change in an audio signal between input and the output.
DNR: Dynamic Noise Reduction. A signal-processing circuit that attempts to reduce the level of high-frequency noise. Unlike Dolby NR, DNR doesn't require preprocessing during recording.
Dolby B: A noise-reduction system that increases the level of high frequencies during recording and decreases them during playback.
Dolby C: An improvement on Dolby B that provides about twice as much noise reduction.
Dolby Digital: An encoding system that digitally compresses up to 5.1 discrete channels of audio (left front, center, right front, left surround, right surround, and LFE) into a single bitstream, which can be recorded onto a DVD, HDTV broadcast, or other form of digital media. When RF-modulated, it was included on some laser discs, which requires an RF-demodulator before the signal can be decoded. Five channels are full-range the .1 channel is a band-limited LFE track. A Dolby Digital processor (found in most new receivers, preamps, and some DVD players) can decode this signal back into the 5.1 separate channels. Most films since 1992`s Batman Returns have been recorded in a 5.1 digital format, though a number of films before that had 6-channel analog tracks that have been remastered into 5.1.
Dolby EX: An enhancement to Dolby Digital that adds a surround back channel to 5.1 soundtracks. The sixth channel is matrixed from the left and right surround channels. Often referred to as 6.1. Sometimes referred to as 7.1 if the system uses two surround back speakers, even though both speakers reproduce the same signal. Software is backwards-compatible with 5.1 systems, but requires an EX or 6.1 processor to obtain additional benefit.
Dolby Pro Logic: An enhancement of the Dolby Surround decoding process. Pro Logic decoders derive left, center, right, and a mono surround channel from two-channel Dolby Surround encoded material via matrix techniques.
Dolby Pro Logic II: An enhanced version of Pro Logic. Adds improved decoding for two-channel, non-encoded soundtracks and music.
Driver: A speaker without an enclosure also refers to the active element of a speaker system that creates compressions and rarefactions in the air.
DSP: Digital Signal Processing. Manipulating an audio signal digitally to create various possible effects at the output. Often refers to artificially generated surround effects derived from and applied to two-channel sources.
DTS: Digital Theater Systems. A digital sound recording format, originally developed for theatrical film soundtracks, starting with Jurassic Park. Records 5.1 discrete channels of audio onto a handful of laser discs, CDs, and DVDs. Requires a player with DTS output connected to a DTS processor.
DTS ES: An enhanced version of the 5.1 DTS system. Like Dolby's Surround EX, a sixth channel is added. In some cases (DTS ES Discrete), the sixth channel is discrete. Software is backwards-compatible with 5.1 systems, but requires an ES or 6.1 processor to obtain additional benefit. Neo: 6 is a subset of DTS ES that creates 6.1 from material with fewer original channels.
Dynamic Range: The difference between the lowest and the highest levels in audio, it&'s often expressed in decibels. In video, it's listed as the contrast ratio.
