The Definitive Analogue Heart & Spatial Audio Hub for Elite Studios
Designed exclusively for high-level mix facilities, mastering suites, and console-centric workflows, the Apollo x16 Gen 2 Ultimate+ Edition bypasses built-in microphone preamps to focus entirely on conversion transparency and dense line-level routing. Offering 16 input and 18 output channels of balanced analog I/O via standard DB25 connectors, it serves as the ultimate high-headroom bridge to route signals into summing mixers, high-voltage tube gear, and complex external signal chains.
The landmark feature of this Gen 2 evolution is its breathtaking monitoring path. Backed by hardware-accelerated Apollo Monitor Correction powered by Sonarworks® and a native, multi-channel speaker matrix that supports immersive audio formats up to 9.1.6 Dolby Atmos, it allows you to tune and manage your space with absolute authority. Combined with premium high-bandwidth Thunderbolt 3 connectivity and low-latency stability across macOS and Windows, the interface utilizes hybrid processing power—letting you blend its onboard HEXA Core DSP acceleration with your computer's native CPU resources to effortlessly lift massive, multi-track studio sessions.
6-CORE HEXA CORE PROCESSING: Six dedicated internal SHARC DSP chips offload all analog modeling calculations entirely from your computer's CPU.
126+ ULTIMATE+ PLUG-INS INCLUDED: Unlocks UA’s most expansive software collection featuring full, premium suites from Neve, SSL, Manley, Avalon, and more.
ELITE GEN 2 MONITOR D/A: Completely overhauled converter array delivering an industry-best 133 dB dynamic range and a near-invisible -129 dB THD+N.
16x16 PRO ANALOG DENSITY: Balanced high-headroom line-level inputs and outputs across four standard DB25 connectors, optimized for consoles and patchbays.
9.1.6 IMMERSIVE AUDIO SUPPORT: Native control room routing and monitoring configurations for Dolby Atmos and multi-channel surround sound configurations.
APOLLO MONITOR CORRECTION SUPPORT: Loads Sonarworks® SoundID Reference speaker tuning profiles directly onto the internal DSP with near-zero latency.
SWITCHABLE OPERATING REFERENCE: Easily swap headroom settings between +20 dBu and +24 dBu via software to seamlessly match professional external audio hardware.
UPDATED UAD CONSOLE APP: Features instant MIDI-switchable Plug-In Scenes, integrated sub-bass crossover management, and flexible cue routing.
NATIVE LUNA DAW INTEGRATION: Deep software binding with Universal Audio’s LUNA Recording System for an organic, zero-latency analog console workflow.
