What Is B-Stock?
Product Description
The Apollo x4 Heritage Edition is a professional desktop audio interface that combines Universal Audio's cutting-edge analogue emulation with elite conversion and processing capabilities. This special edition builds upon the acclaimed Apollo x4, adding a premium suite of 10 UAD plug-ins valued at over $2,400, including collections from Helios, Fairchild, Teletronix, Pultec and Universal Audio. With QUAD Core real-time UAD processing and four Unison-enabled mic preamps, you can track and mix through the most accurate classic hardware emulations available, all with near-zero latency.
Designed for serious music creators and producers, the Apollo x4 delivers 127 dB dynamic range and -117 dB THD+N for truly world-class sound quality. Seamless integration with the LUNA Recording System (Mac only) and compatibility with all major DAWs makes it a flexible centrepiece for any professional studio. Its 12-in, 18-out configuration, built-in talkback mic, dual headphone outputs, and ADAT/SPDIF expandability make it ready for a wide variety of tracking and mixing scenarios. The Apollo x4 Heritage Edition provides scalable performance for any growing studio.
Key Features:
- Elite-class audio conversion:
Enjoy ultra-clean sound with 127 dB dynamic range and ultra-low distortion, rivaling much more expensive dedicated converters. - Heritage Edition plug-in bundle:
Includes 10 award-winning UAD plug-ins from iconic brands such as Teletronix, Pultec, Helios and Fairchild, with lifelike analogue modelling. - Four Unison-enabled preamps:
Track through authentic mic preamp emulations from Neve, API, Avalon, Manley and more, capturing input character and circuit behaviour.
Realtime UAD Processing & Plug-ins:
The Apollo x4 Heritage Edition offers real-time tracking with Universal Audio’s acclaimed UAD plug-ins, using its built-in QUAD Core DSP. This allows you to monitor and record with near-zero latency, running classic compressors, equalisers, tape machines and guitar amps as though you were using the original outboard gear. The included Heritage Edition bundle provides access to iconic tools like the LA-2A, 1176, Fairchild and Pultec collections, delivering top tier sound sculpting straight out of the box.
Unison Preamps & Instrument Inputs:
Unison technology gives you access to the exact tone and feel of vintage mic preamps and guitar amps, thanks to its unique hardware-software integration. With four Unison-enabled mic inputs and dual front-facing Hi-Z inputs, the Apollo x4 Heritage Edition accurately replicates impedance, gain staging and circuit nuances from famous brands like Neve, Helios, Marshall and Fender. It’s ideal for vocal tracking, guitar recording, or any signal chain where authentic analogue tone matters.
LUNA Integration & Scalability:
When used with a Mac system, the Apollo x4 becomes even more powerful through integration with the free LUNA Recording System. LUNA offers a seamless, single-window workflow and deep Apollo interface control, enhanced by exclusive LUNA Extensions and Instruments. Users can also scale their studio by connecting up to four Thunderbolt Apollo interfaces and six UAD devices for greater I/O and DSP power, making Apollo x4 a central hub for growing studios.
