The Universal Audio Apollo x4 Heritage Edition audio interface leads its class in performance and features. In addition to all the benefits of the interface, the special Heritage Edition adds a diverse package of premium UAD plug-ins at an unprecedented value—they could total over $2,400 if purchased separately. The Apollo x4 delivers elite-class A/D and D/A conversion, four Unison-enabled preamps and QUAD Core real-time UAD plug-in processing. It accomplishes all of this in a sleek, desktop unit with Thunderbolt 3 connectivity for Mac and Windows.

Premium UAD Plug-Ins—Over $2,400 Value

Apollo x4 Heritage Edition comes with 10 premium award-winning plug-in titles valued at over $2,400—including the full suite of UA's Teletronix, 1176 and Fairchild compressors, Helios Type 69, V76 and UA 610 mic preamps, all Pultec EQs, Oxide Tape Recorder and Pure Plate Reverb. These premium Heritage Edition titles are in addition to the Apollo x4's included Realtime Analog Classics Plus bundle, giving you the most accurate library of classic analog emulations included with any professional audio interface. A hallmark feature of Apollo is its Realtime UAD Processing, letting you run the full library of UAD plug-ins at near-zero latency.

Four Unison Preamps

Apollo x4 features four Unison-enabled mic preamps, letting you track through exacting mic preamp emulations from Neve, Helios, API, Manley, UA and many more. Unison technology nails the tone of these sought-after tube and solid state mic pres—including their input impedance, gain stage “sweet spots,” and the component-level circuit behaviors of the original hardware.

Dual Headphone Outputs

UA knows that much of the best music is collaborative—that's why the Apollo x4 includes two headphone outputs, for perfect monitoring and playback at high quality. It's perfect for simulataneous recording of two musicians. It's also an essential feature for engineers who want to fine-tune the sound while recording a musician.

Apollo x4 Elite-class conversion

Elite-class A/D and D/A Conversion

Apollo desktop interfaces are used to create exceptional-sounding records every day. To improve upon the previous generation, Universal Audio engineers designed the Apollo x4’s audio conversion to deliver a striking 127dB dynamic range and -117dB THD+N, giving Apollo x4 a spacious, organic sound that easily rivals dedicated high-end converters costing much more.

Plus, with a total of four line outs, optical ADAT/SPDIF input and output, dedicated monitor remote controls and a built-in Talkback mic, the Apollo x4 can serve as the powerful centerpiece of a professional desktop studio.
