Digital Network Audio Amplifiers
DNA20 (4 x 480W into 2.7R) in 1U | DNA40 (4 x 1400W into 2.7R) | DNA80 (4 x 2200W into 2.7R) | DNA100(4 x 3700W into 2.7R) | DNA120(2 x 6250W into 2.7R)
Now you don’t have to choose between the highest quality amplification, and digital audio networking (optional) convenience. Or between incredible power and the ability to work within analogue or digital systems. You can have it all.
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 (optional).
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.

The MC2 Delta 20 and the DNA20 from XTA may both be fitted with a four channel analogue crossover card that offers the following facilities:
– Four channels of 12 or 24dB/Octave slope high and low pass crossover filtering (including Linkwitz-Riley)
– Mono summing of channels A+B or C+D for sub-bass applications — mono summing will reduce the roll-off available on the high pass filter to 12dB/Oct.
– Low frequency contouring (shelving filter) on channels A & C, high frequency contouring on channels B & D. Preset turnover frequency but internally adjustable cut/boost.
