Elite-Class A/D and D/A Conversion 
With thousands of chart-topping songs and hundreds of Grammy-winning albums under their belt, Apollo interfaces are no strangers to tracking stellar-sounding records. To improve on the previous generation Apollo interfaces’ class-leading audio conversion, UA engineers obsessively auditioned the latest A/D and D/A converters — ultimately pairing elite-class 24-bit/192 kHz converters with all-new analog circuitry for an ultra-pristine signal path. 
 
With 129 dB dynamic range and -128 dB THD+N, Apollo x6’s open, natural sound quality rivals any dedicated high-end converter on the market — regardless of price — and is the perfect starting point for applying UAD processing.  
 
Realtime UAD HEXA Core Processing
Apollo x6 features HEXA Core processing, with six DSP chips and 50% more UAD plug-in processing power than previous Apollos. 
 
Unison™ Technology: The Genuine Sound of Neve, API, & Manley Preamps
Perfect for electronic musicians and post production professionals who don’t require tons of mic inputs, Apollo x6 features two Unison-enabled mic preamps, letting you track through exacting mic preamp emulations from Neve, API, Manley, SSL, and Universal Audio.** A Universal Audio exclusive, 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. 
LUNA Recording System — Deep Apollo Integration with a Fast, Natural Workflow
Apollo X series interfaces work with all major DAWs. But they become a fully integrated recording system with LUNA, a powerful new 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, full AU support, and access to a suite of exclusive LUNA Instruments and Extensions.
