XTA is a leading professional audio company based in the UK. With a history stretching back over 25 years and being at the forefront of DSP technology, XTA design and manufacture professional amplification and digital audio management products used extensively around the world in both live touring and installed applications. Thanks to the company’s background in live production audio XTA has a wealth of knowledge in just what’s required to produce the highest quality audio with the best processing and simplest (stress-free) control. All XTA products are covered by a 5-year warranty.

Overview

4 Channel Digital Network Amplifier 4x 200W / 100V

The DNA Series offers the assurance of XTA’s highest quality audio power amp technology with future proofing via the inclusion of simple to use digital audio networking.

Fast rear panel switching allows the amplifier to accept either four channels of analogue audio or pick up four channels of networked audio, via Dante, which is then converted using 24 bit 96kHz DACs.

Connect to an DPA amplifier using a single CAT5 cable to realise a stereo 4 way system with no further external processing required. Switch back to analogue to use as a powerful traditional quad channel amplifier. Run bridged channel pairs or link adjacent inputs for total flexibility in either analogue or digital mode.

Within this 1U chassis, the DNA20 also features individual 70/100V line drive, an auto-standby power mode (with near-instant wake-up at <1s), tuneable fans adaptable to different level/performance scenarios, and GPIO for remote control and monitoring. The amplifier also supports the back-up amplifier inputs as on the DNA40, and has a PFC enabled universal mains supply for worldwide use.
