XTA DP648 4-in 8-out Signal Processor
With a seamless and intuitive workflow, robust construction, and audiophile-grade sound quality, the Six series makes premium performance both accessible and effortless. Six series sets a new standard for audio processors, delivering unparalleled audio excellence.
Building on XTA’s groundbreaking and iconic DSP legacy, Six introduces a cutting-edge platform that takes innovation to the next level. Designed for versatility, it excels in a wide range of applications, from live sound and installations to studio and audiophile environments.
Equipped with newly designed circuitry, ultra-low noise audiophile components, and state-of-the-art processing algorithms, the Six series delivers the ORIGINAL and BEST of British audio DSP to the world. You asked – We delivered!
Bringing together the best features of our DP548, the processing platform found in our DPA amplifiers, and a sleek software/management interface via globcon XTA/MC2 edition**, we introduce Six. Six is designed to cover all your audio needs from every angle.
4 useable inputs across 12 available sources (analogue, AES, Network Audio option)
8 useable outputs across 3 possible formats (analogue, AES, Network Audio option)
Full front panel control of every parameter—always within reach
Ethernet control via new globcon software (coming soon)
Enhanced visibility with improved metering—an oversized OLED display gives you a comprehensive overview of your mix!
5 year warranty – 100% UK designed & Manufactured
Additionally…
New ESS conversion chips have been used that raise the bar in terms of audio signal integrity.
A bulletproof tried and tested universal (silent) switchmode PSU is utilised for efficiency and reliability.
Silent (fanless*) operation makes Six perfect for studio and audiophile applications, where all you want to hear is the music
A subtle but fresh look to match the MX36 but still maintaining that XTA dna.
MX + Six
Partnering Six processors*** with the MX36 offers unparalleled control, distribution, and handling of those multiple audio signals across multiple formats, with ultimate care of the signal from input to output, only adding and routing what you choose, and when you choose it. The flexibility and futureproofing that this combination brings to your audio toolkit is truly exceptional.*network audio usage may require a low noise fan (supplied with network modules) | ** globcon control coming soon | *** 648 is the flagship release model – Others will follow in 2025
