Universal Audio Apollo x4 Heritage Edition
Apollo x4 Heritage Edition
A Special Edition of Universal Audio’s Acclaimed Apollo x4 Interface, with a Bundled UAD Plug-In Package Worth over $2,400.
Apollo x4 Heritage Edition has all the benefits of the acclaimed Apollo x4, including elite-class A/D and D/A conversion, QUAD Core realtime UAD plug-in processing, Unison-enabled mic preamps, and full LUNA Recording System integration. And it goes a step further, with a software suite of 10 award-winning UAD plug-in titles, featuring Collections from Helios,® Fairchild,® Teletronix,® Pultec,® and UA.
A Special Edition featuring Iconic UAD Analog Collections Onboard
A hallmark feature of Apollo is its Realtime UAD Processing, letting you run the full library of UAD plug-ins at near-zero latency. Taking you a step further, Apollo x4 Heritage Edition gives you 10 premium plug-in titles worth over $2,400 — including the full suite of UA’s Teletronix, 1176, and Fairchild compressors, Helios Type 69, V76, and UA 610 Unison mic preamps, all Pultec EQs, Oxide Tape Recorder, and Pure Plate Reverb.
These premium Heritage Edition titles are in addition to Apollo Twin x4’s included “Realtime Analog Classics Plus” bundle, giving you the most accurate library of classic analog emulations included with any professional audio interface.
Four Unison Preamps — The Sound of Neve, Helios, API, Avalon & More
Apollo x4 Heritage Edition features four Unison-enabled mic preamps, letting you track through exacting mic preamp emulations from Neve, API, Manley, SSL, Avalon, Helios, and Universal Audio.* A Universal Audio exclusive, Unison is a proprietary hardware-software integration that nails the tone of these sought-after tube and solid-state mic pres — including their input impedance, gain stage “sweet spots,” and component-level circuit behaviors.
Unison technology is also found on Apollo x4’s dual front-panel Hi-Z instrument inputs, providing dead-on impedance and gain matching for guitar and bass amp models from Fender, Marshall, Ampeg, and more.
Elite-Class A/D and D/A Conversion
With thousands of hit songs and hundreds of Grammy-winning albums under their belt, Apollo interfaces are used to create exceptional-sounding records every day. To improve upon the previous generation, UA engineers redesigned the Apollo x4’s audio conversion to deliver a striking 127 dB dynamic range and -117 dB THD+N, giving it a spacious, organic sound that easily rivals dedicated high-end converters costing much more.
LUNA Recording System — Deep Apollo Integration with a Fast, Natural Workflow
All Apollo X series interfaces work with all major DAWs, including Logic Pro, Ableton Live, Pro Tools, and more. But they become a fully integrated recording system with LUNA, a powerful recording application for Mac from Universal Audio. Bolstered by Accelerated Realtime Monitoring,™ LUNA lets you track and mix in an intuitive single-window workflow with unlimited track counts, with full AU support and access to exclusive LUNA Instruments and Extensions.
Additional Connections & Built-in Talkback Mic
With its four Unison-enabled preamps, six line outs, and optical ADAT/SPDIF input — plus dedicated monitor remote controls and a built-in Talkback mic — the 12 x 18 Apollo x4 Heritage Edition gives you the I/O you need for professional tracks and mixes.
Professional Performance and Scalability
Users of Apollo x4 Heritage Edition can combine up to four Thunderbolt-equipped Apollos and six total UAD-2 devices — adding I/O and DSP as your studio grows. Once you expand your studio with an Apollo X rackmount unit, you can use Apollo x4 as a desktop monitor controller with additional I/O and DSP power.

Level Knob – The Level knob controls multiple functions. The knob’s current function is selected with the PREAMP and MONITOR buttons. When in PREAMP Mode, rotate clockwise to increase the amount of preamp gain for the currently selected input channel. When in MONITOR Mode, rotate clockwise to increase the monitor or headphones volume, depending on the stereo output currently selected with the MONITOR button.
Preamp Gain & Volume Level Indicator LEDs – The LEDs surrounding the Level knob indicate the relative level of the selected function (either input channel preamp gain or monitor/headphone volume)
Channel Selection Indicators – The currently selected input channel is indicated by the lit channel name (CH1, CH2, CH3, or CH4) above its input meter.
Input Meters – The four input meters display signal levels for each of the analog input channels.
Input Source Indicators – These indicators show which input source jack (MIC, LINE, or HI-Z) is active for the selected input channel.
Selected Stereo Output – These indicators display which stereo output (MONITOR, HP1, or HP2) is currently selected for volume control with the Level knob.
Stereo Output Meters – These meters display the main stereo signal output bus levels
Options Display – This panel displays the state of the preamp and monitor options, which are controlled by the six Option Buttons.
(a) INPUT Select Selects the active input source jack for the currently selected channel. The current selection is displayed by the Input Source Indicators.
(b) FILTER Enables a low cut (high pass) rumble filter with a cutoff frequency of 75 Hz.
(c) +48V Enables +48-volt phantom power for the mic input. Phantom power is typically needed for condenser microphones.
(d) PAD Attenuates (lowers) the XLR mic input signal level by 20 dB.
(e) POLARITY Ø Inverts the polarity (aka “phase”) of the input signal.
(f) LINK Links input channels 1 and 2 as a stereo pair.
(g) TALK Activates the built-in talkback microphone and the DIM function.
(h) DIM Reduces the monitor output volume level. The amount of DIM attenuation is set in the companion Console software.
(i) ALT (Alternate) Switches the main monitor mix to an alternate set of outputs
(j) FCN (Function) This switch can be assigned to control one of three monitoring functions.
(k) MONO Sums the left and right signals of the stereo monitor mix into a monophonic signal.
(l) MUTE Mutes the monitor outputs.
PREAMP Button – Press this button to enter PREAMP Mode and activate the input channel controls. Press again change the selected input channel.
Option Buttons – Each of the six Option Buttons has dual functions. In Preamp mode, the buttons control the preamp options for the currently selected input channel. In Monitor mode, the buttons control the monitor and headphone options. The individual options for both modes are detailed in this section.
Monitor Button – Press this button to enter MONITOR Mode and activate the monitor and headphone controls. Press again to change the currently selected stereo output so it can be adjusted with the Level knob.
