Audient Horizon 16 34x34 Thunderbolt 3 Audio Interface

The Ultimate Bridge for Your Hybrid Studio

The Audient Horizon 16 is a flagship 34-in / 34-out Thunderbolt 3 audio interface and AD/DA converter engineered specifically for mixing engineers, mastering facilities, and commercial hybrid studios. Designed to sit at the core of hardware-focused setups, it bridges the gap between boutique analogue outboard gear and digital audio workstations with absolute transparency. By providing 16 channels of primary line-level analogue I/O alongside dedicated print paths, the Horizon 16 allows you to keep an entire rack of analogue compressors, EQs, and summing mixers permanently patched and instantly accessible.

Uncoloured Mastering-Grade Conversion
Featuring flagship ESS Sabre 32-bit converters (ES9823PRO and ES9039) alongside ultra-low-noise OPA op-amps, the Horizon 16 delivers a staggering 133 dB of monitoring dynamic range and surgical transient precision. Every detail of your analogue signal chain returns to your DAW exactly as it left—completely transparent and free from digital coloration or distortion.

Sub-Millisecond Native Performance
By leveraging a high-bandwidth Thunderbolt 3 architecture, the Horizon 16 achieves an ultra-low 0.99 ms round-trip latency at 192 kHz (64-sample buffer). This allows you to track and monitor through your native VST, AU, or AAX plugin processing in real time without CPU bottlenecks or restrictive proprietary DSP hardware.

Dedicated Mix-Bus Print Path
In addition to its primary DB25 analogue connections, the Horizon 16 includes dedicated stereo mix-bus inputs and independent monitor outputs. This dedicated architecture lets you print your final analogue master or summing box mix-down back into your DAW without disconnecting or re-routing any of your 16 analogue line channels.
