Designed to take pride of place in professional studio racks, the Apollo x6 Gen 2 Studio+ Edition targets producers and engineers who prioritize massive DSP plugin power, premium mixing translation, and extensive line-level connectivity over a high microphone preamp count. It provides the ultimate link for hybrid studio setups, allowing you to interface seamlessly with hardware synthesizers, samplers, outboard compressors, and summing mixers while unlocking UA's most comprehensive premium software package.
The standout enhancement of the Gen 2 series is its redesigned monitoring path. Equipped with flagship digital-to-analog converters and Dual-Crystal Clocking, it delivers a massive 130 dB dynamic range for clinical monitoring precision. Utilizing a high-bandwidth Thunderbolt 3 connection with specialized low-latency drivers across macOS and Windows, the onboard HEXA Core hardware processing matrix offloads your entire UAD plugin workload from your computer’s CPU, keeping your digital audio workstation (DAW) fast, agile, and free from latency bottlenecks.
Product Description
Premium Studio+ Software Suite: A Boutique Outboard Rack:
The core highlight of the Studio+ Edition is its extensive software footprint. Moving far beyond entry-level tracking plug-ins, this comprehensive bundle provides a virtual boutique outboard rack with over 50+ premium titles modeled down to the component level:
Elite Outboard Preamps & Channel Strips: Track through legendary signal paths like the Avalon VT-737sp Tube Channel Strip, Manley Reference Microphone Preamp, and Helios Type 69 Preamp & EQ.
Classic Dynamic Control: Sculpt your sounds with the Empirical Labs Distressor, dbx 160 Compressor/Limiter, and UA 175B/176 Tube Limiters, plus complete legacy collections of the Teletronix LA-2A and UA 1176.
Premium Reverb & Tape Warmth: Inject deep depth and vintage tape saturation using the Lexicon 224 Digital Reverb, Capitol Chambers, and the Studer A800 Multichannel Tape Recorder.
Virtual Instruments: Compose tracks with flagship engines like the Moog Minimoog synthesizer, Opal Morphing Synth, and the pristine Ravel Grand Piano.
Elite Gen 2 Audio Fidelity & Room Calibration:
The foundation of the Apollo X Rackmount Gen 2 series is its masterfully updated digital conversion layout. With a monitor path delivering 130 dB of dynamic range and an astonishingly low -127 dB THD+N, the x6 Gen 2 ensures that your multi-track arrangements, transient details, and stereo fields translate with absolute accuracy.
To counteract imperfect room acoustics, the interface runs Apollo Monitor Correction powered by Sonarworks®. This allows engineers to import custom SoundID Reference room correction filters directly into the interface’s internal DSP hardware chip. The system applies up to 24 precision EQ filters with speaker time-alignment under zero added system latency, letting you monitor through a perfectly flattened frequency curve without sacrificing host computer performance.
Two Unison Preamps with Assistive Auto-Gain:
For vocal and instrument tracking, the front panel features two Unison-enabled microphone/line combo preamps and dual Hi-Z instrument inputs. Unison technology creates a physical, bi-directional hardware circuit sync that matches the precise input impedance, gain-stage sweet spots, and component interactions of iconic vintage gear from Neve, API, SSL, and Manley. To accelerate tracking setups, the Gen 2 introduces Assistive Auto-Gain. By clicking a single software button in the UAD Console app, the Apollo analyzes your incoming signal and sets the perfect input level gain structures automatically, safeguarding your tracking session from sudden digital clipping.
Surround Sound Monitoring & Bass Management:
The Apollo x6 Gen 2 is a fully capable multi-channel hub, offering native mixing and monitoring support for surround formats up to 5.1. Inside the upgraded UAD Console App, users gain access to comprehensive hardware-driven Bass Management. This lets you integrate studio subwoofers and configure custom low-frequency crossover boundaries directly within the DSP matrix, rendering deep low-end control. The sleek, pale-grey front panel also includes physical keys for Alt speaker switching, Mono summing, Dim, and an integrated Talkback Microphone for instant studio communication.
Key Features
