The OA21 ONIX AUDIO DNA-45/50 a 100W RMS per channel, integrated amplifier. It has upgradeable discrete Vinyl boards with internal consumer Bluetooth boards to follow, all with a traditional 250VA TOROIDAL TRANSFORMER power supply. Crafted in a package formed of solid aluminum, that's powder coated in the UK ( The DNA 45 is supplied without a Vinyl Board and an optional upgrade is required if you wish to use it with Vinyl )
At 10KG ( 22 LBS ) 100% aluminum, 435mm wide ( 17.12 Inches ) 285mm deep ( 11.2 Inches ) and still only 45mm high ( 1.78 Inches ) - we have achieved the thinnest amp to date with evolution of the OA21s inside. The construction being 100% aluminum creates the ultimate heat sink - eliminating vents that normally cause weakness and reliability issues if in a closed environment. In addition the ONIX DNA 50/45 becomes a FARADAY cage that eliminates unhealthy EMF. The FARADAY cage is explained Click here
If the OA21 DNA-45/50 was made with stainless steel instead of aluminum, it would weigh 32KG ( 71 LBS ) . Not everyone wants a huge audio elephant in their ever decreasing living spaces of today's world. The OA21 DNA-50 can be enclosed or hidden and is capable of taking up to 100KG ( 220 LBS ) on the top, such as a large screen TV or other separates. It can be used at any angle with no compromise for function, sound or heat while in use.
The DNA-45/50 is afull size evolution of The Classic ONIX AUDIO OA21 and 35 years of experience. Designed by the same people, using the same know how from years of ONIX AUDIO and the classic OA21s as its starting reference . Creating a signal path and unrivaled imaging of sound, that time and MP3 have forced too many to forget.
This is the new digital world, but we still have analogue ears and at OA21 / ONIX AUDIO we never forgot it.
Newsflash:
OA21 products are made by people that listen to music for people that do too, and they ARE made in England.
Quote :- "The DNA-50 amplifier has a real solidity and assuredness that you don’t even bother to seek out its purported strengths or weaknesses, you simply sit back, relax, spin your favourite tunes and be comprehensively drawn right in by the clarity, power and emotion of the music."
Quote :- "The DNA-50 unveils plenty of detail and lets you know what's going on without making you think about the sound: in other words, the emphasis is on the music."
