Audient Horizon 32 Thunderbolt Audio Interface

Audient Horizon 32 — Flagship 50-in/50-out Thunderbolt 3 Audio Interface

The Audient Horizon 32 is a 50-in/50-out Thunderbolt 3 audio interface built to bridge a console or outboard rack to a DAW from a single rack unit. It delivers 32×32 channels of primary analogue line I/O across eight DB-25 connectors, with dedicated stereo Mix-Bus Inputs and Monitor Outputs. This interface is the right choice for commercial rooms and hybrid studios that need uncompromising conversion on macOS.

Mastering-Grade Conversion Path

ESS ES9823PRO and ES9039 converters deliver a 133 dB dynamic range that preserves the full width and detail of the analogue source. OPA1602 and OPA1612 op-amps handle transient capture, and a hybrid analogue/digital PLL clock circuit keeps jitter attenuation rock-solid. Fanless cooling keeps the chassis silent in machine-room-free control rooms.

Console-Scale I/O Without Repatching

32 bidirectional line-level channels over eight DB-25 connectors, plus stereo Mix-Bus Line Inputs and stereo Monitor Line Outputs. Dual ADAT I/O adds 16 channels of digital expansion, and BNC Word Clock I/O with switchable termination locks the unit in complex digital rigs.

• Total I/O: 50 in / 50 out — enough to bridge a console or full outboard rack
• Primary Analogue Line I/O: 32 in / 32 out via 8 DB-25 connectors
• Digital Expansion & Sync: Dual ADAT I/O (16 channels) plus BNC Word Clock I/O with switchable termination

32-bit / 192 kHz Conversion with Sub-Millisecond Latency

32-bit AD/DA at sample rates up to 192 kHz, with a measured 0.99 ms round-trip latency at 192 kHz with a 64-sample buffer — the benchmark for real-time native plugin monitoring through VST/AU/AAX chains.

• Converter Resolution: 32-bit / 192 kHz AD/DA
• Dynamic Range: 133 dB — preserves the full width and detail of the analogue source
• Round-Trip Latency: 0.99 ms @ 192 kHz, 64-sample buffer
• Converter Chips: ESS ES9823PRO and ES9039

Scalable Architecture in a 1RU Chassis

Daisy-chain up to four units on a single macOS driver for a 200-in/200-out facility without changing the workflow. The all-metal 1RU chassis weighs 4.4 kg, with a high-resolution Motion UI display and Horizon Control software for routing, monitoring, and metering.

• Scalability: Up to 4 units / 200 in × 200 out on a single macOS driver
• Chassis: 1RU all-metal, 48.3 cm × 33 cm × 4.45 cm
• Weight: 4.4 kg
• OS Support: macOS only, forward-compatible with Thunderbolt 4 and 5
