Audient Horizon 32 50-Input/ 50-Output TB3 Audio Interface w/ 32 Channels Analog I/O

Audient's Horizon 32 delivers 50-in/50-out Thunderbolt 3 connectivity with 32 channels of primary analogue I/O across eight industry-standard DB25 connectors, turning this 1RU interface into a transparent hub for outboard racks, console integration, and summing workflows. The mastering-grade 32-bit AD/DA converters measure 133dB of dynamic range, using flagship ESS ES9823PRO and ES9039 chips paired with ultra-low noise OPA1602 and OPA1612 op-amps to capture transients with surgical precision. Round-trip latency sits at 0.99ms at 192kHz with a 64-sample buffer, making native plugin tracking genuinely viable without proprietary DSP constraints.

The dedicated stereo mix-bus path keeps all 32 D-Sub I/O permanently connected to outboard gear while providing a separate print path for final mixdowns from consoles or summing boxes. Dual ADAT I/O adds 16 channels of digital expansion, and BNC word clock I/O with switchable internal termination handles complex sync environments. Selectable reference levels of +18dBu and +24dBu calibrate the interface to match analogue gear headroom precisely. The unified macOS driver supports system expansion up to 200×200 I/O across four units, with forward compatibility for Thunderbolt 4 and 5. Horizon Control software and the Motion UI hardware display provide a routing matrix, custom monitor layouts, polarity inversion, dim, and simultaneous metering across all D-Sub banks.

Fanless thermal design maintains silent operation in control rooms without machine closets, while the full-metal black chassis weighs 4.4kg and measures 48.3cm wide by 33cm deep by 4.45cm high. The interface is macOS-only, with rock-solid TB3 drivers that minimise CPU overhead and eliminate the need to disable system security settings. Hybrid analogue/digital PLL circuits attenuate jitter for stable stereo imaging, and the rugged 1RU construction handles continuous 24/7 studio operation.
