Universal Audio Apollo X4 Heritage Edition Audio Interface

The Apollo x4 Heritage Edition delivers professional studio-grade recording capabilities with an exceptional collection of vintage analogue emulation plug-ins worth over $2500 USD included at no extra cost. This desktop Thunderbolt 3 audio interface combines four Unison-enabled microphone preamps with QUAD Core UAD processing, offering musicians and producers the ability to track through authentic recreations of legendary hardware from Neve, API, Helios, and Manley whilst maintaining near-zero latency performance.

Built upon Universal Audio's six decades of audio engineering expertise, the Apollo x4 features premium A/D and D/A converters with an impressive 127 dB dynamic range that rivals dedicated high-end conversion units. The interface's Unison technology physically reconfigures input impedance to match original vintage preamps, capturing the exact tonal characteristics and circuit behaviours of classic tube and solid-state designs. With 12 inputs and 18 outputs, dual headphone outputs, Hi-Z instrument inputs, and comprehensive monitoring controls including talkback functionality, this unit serves as a complete desktop studio centrepiece.

The Heritage Edition bundle includes the complete Realtime Analog Classics Plus collection featuring authentic emulations of the Teletronix LA-2A, 1176LN compressors, Fairchild 670, Pultec EQs, and UA 610-B Tube Preamp. Additionally, users receive exclusive Heritage Edition plug-in collections from Teletronix®, Fairchild®, Pultec®, and Helios® manufacturers. The system integrates seamlessly with the included LUNA recording software and supports expansion up to four Apollo units, allowing studios to scale their I/O and DSP processing power as requirements grow.
