About the XTA 4 Series
The XTA 4 Series is an audio management system family comprising five models: the DP424 (2 In 4 Out), DP426 (2 In 6 Out), DP444 (4 In 4 Out), DP446 (4 In 6 Out), and DP448 (4 In 8 Out). All units feature electronically balanced inputs and outputs with AES/EBU fitted as standard, a dynamic range exceeding 116dB, and distortion below 0.001% at 1kHz. DSP tools include eight parametric filters per input, nine per output, a 28-band graphic equaliser on each input, Bessel, Butterworth and Linkwitz-Riley crossover filters, and a fully configurable limiter with clip/D-max look-ahead. Maximum delay is 650ms, and output gain is adjustable in 0.1dB steps. RS485 in/out via XLR connectors supports system networking.
XTA 4 Series — buyer FAQs
What is the XTA 4 Series and which models does it include?
The XTA 4 Series is a family of five professional audio management processors: the DP424 (2 in / 4 out), DP426 (2 in / 6 out), DP444 (4 in / 4 out), DP446 (4 in / 6 out), and DP448 (4 in / 8 out). All five share a common feature set including AES/EBU connectivity fitted as standard, electronically balanced inputs and outputs on 3-pin XLR connectors, and RS485 networking via XLR.
What DSP processing does the XTA 4 Series provide?
Every unit in the range includes eight parametric filters per input and nine per output, a 28-band graphic equaliser on each input, and phase filtering adjustable in 2-degree steps. Crossover options cover Bessel, Butterworth and Linkwitz-Riley alignments at multiple slopes. A configurable limiter handles threshold, attack and release settings, and a clip/D-max look-ahead limiter is also included. Maximum delay is 650ms.
Who makes the XTA 4 Series and where does it sit in their range?
XTA Electronics is a British manufacturer based in Stourport-on-Severn, England, specialising in digital audio signal processing and loudspeaker management systems for touring and installed sound, with products designed and manufactured in the UK. The 4 Series sits as a multi-model processor family within that loudspeaker management focus, offering buyers a choice of input/output configuration to match the scale of a given system.
What audio performance figures does a used XTA 4 Series unit deliver?
The 4 Series specifies a dynamic range exceeding 116dB (20Hz to 20kHz, unweighted), distortion below 0.001% at 1kHz and +10dBm, and a frequency response of plus or minus 0.5dB from 10Hz to 32kHz. Output gain is adjustable from +15dB to -40dB in 0.1dB steps. Maximum output level is +20dBm into a 600-ohm load.
What should I check when buying a second-hand XTA 4 Series unit?
Confirm which of the five models you are looking at, since input/output count varies across the range. Check that all XLR inputs, outputs and RS485 ports are functional, that the DSP processing is fully operational across all channels, and note whether optional output transformers are fitted. Each listing on this page describes the individual unit's condition. Used purchases here carry a 21-day warranty covering major functional faults; full details are in the buying guide at 10kused.com/used-av-equipment-guide/.
