Introducing the Universal Audio Apollo Twin X DUO USB HE (Desktop/WIN), your gateway to top-tier A/D and D/A conversion via two Unison-enabled preamps. These exceptional preamps seamlessly integrate with the DUO Core real-time plug-in processing. In this Heritage Edition package, you'll also receive an impressive collection of five additional award-winning UAD plugins (a value of over 1,500 GBP) to supercharge your processing capabilities (details below).

Evolved from the original Apollo Twin X, the Twin X DUO USB boasts a completely redesigned AD/DA conversion system that competes with high-end converters, delivering a warm and authentic audio reproduction.

This means you can harness Universal Audio's extensive plugin library right at the recording stage. Imagine infusing your recordings with digital preamp emulations or compression right from the start of your workflow. All of this groundbreaking technology is elegantly encased, and connectivity is a breeze with USB 3.0, ensuring lightning-fast data transfer.

With a commitment to preserving audio fidelity, the Apollo Twin X Duo USB Heritage Edition offers an astounding 24-bit/192kHz audio resolution, faithfully capturing every subtlety of your sound source.

Key Features:

  • Exclusive Heritage Edition Plugin Bundle - While preserving all the capabilities found in the Apollo Twin X Duo, the Heritage Edition elevates your plugin arsenal by introducing five fresh, acclaimed UAD plugin titles alongside the existing UAD analogue plugin bundle. These latest additions encompass UA's renowned Teletronix and 1176 compressors, a comprehensive array of Pultec EQs, the exceptional UA 610 Unison mic preamps, and the captivating Pure Plate Reverb. With all of these plugins processed in near real-time, the infusion of additional processing power is poised to propel your audio engineering and music production endeavours to unprecedented heights.
  • Re-designed AD/DA Converters - Having already contributed to a vast range of Grammy award-winning albums, the Apollo Twin X continues the Apollo interface's long legacy with its top-of-the-range audio conversion. The custom converters have undergone a fresh redesign, enhancing the overall dynamic range while proudly showcasing an exceptionally low total harmonic distortion (THD). With its elite-class conversion, the Apollo Twin X DUO outperforms standard audio interfaces, ensuring superior sound reproduction.
  • Dual Core DSP Accelerator - What distinguishes Apollo's audio interfaces from standard units is the inclusion of onboard DSP acceleration. In this iteration of the Twin X, you benefit from duo-core DSP acceleration, enabling you to seamlessly utilise DSP-powered plugins offered by Apollo. These plugins feature exclusive emulations of iconic gear from revered names like Neve, Lexicon, Capitol Studios, API, Manley, Ampex, Fender, and more. These groundbreaking emulations have been painstakingly crafted to faithfully replicate the essence of the originals. This innovation brings vintage equipment back to the forefront, allowing you to capture sought-after sounds that have remained elusive.
  • Unison-Enabled Mic Preamps - Boasting two Unison-enabled preamps for live recording in studios, the Apollo Twin X DUO USB HE allows users to get the finest results from UA's preamp emulations. These include Neve, Helios, API, Manley, UA and many more giving you a truly crisp sound which provides you with an array of sound profiles.
  • Combine Interfaces - Intuitively considering any user's studio set up in the future, the Apollo Twin X allows owners to easily connect up to four Apollos and a total of six UAD-2 devices. Meaning expanding your studio set-up has never been easier, in addition, if you add a rack-mountable Apollo to your setup, you're able to take control of it with the Apollo Twin X monitor control features.
  • Various I/O Options - The Apollo Twin X is equipped with a comprehensive array of inputs and outputs designed to meet your diverse needs. In addition to the primary inputs, it also includes headphone outputs and a Hi-Z instrument input. Alongside these, you'll find two line outputs and an ADAT/SPDIF input, ensuring you have a wealth of connectivity options at your disposal.
