Audient Horizon 32

The Audient Horizon 32 is a Thunderbolt 3 audio interface designed for large hybrid studios, professional studios, and project studios with a substantial analog setup. Its 32 line inputs and 32 line outputs via DB25 allow you to connect a mixing console, multiple processing racks, or a summing system to the DAW from a single 1U unit.

Key Features

• 32 line inputs and 32 line outputs distributed across eight DB25 connectors for connecting a mixing console or a large collection of outboard gear.
• A total of 50 inputs and 50 outputs via Thunderbolt 3.
• Dedicated stereo input to the mix bus for recording the master without occupying the main inputs.
• 16 ADAT input and output channels to expand the system with compatible digital converters or preamps.
• 32-bit/192 kHz conversion with a claimed dynamic range of 133 dB.
• Horizon Control centralizes routing, monitoring, levels, and control functions.

Connect a console or multiple racks without adding more interfaces

The Horizon 32 features 32 analog line inputs and 32 analog line outputs on eight DB25 connectors. This capacity is particularly well-suited for studios that wish to interface a full-size mixing console, multiple racks of compressors and equalizers, or an analog summing system while maintaining permanent cabling.

The DB25 format is particularly well-suited for fixed installations with high connection density. However, you’ll need to use multipairs or patch panels compatible with your setup, rather than relying on individual jack connections for each channel.

Reserve a separate path for the final mix

A stereo input dedicated to the mix bus allows you to route the output from a console, a summing mixer, or a master processing chain into the DAW without using two of the 32 main line inputs.

Stereo outputs dedicated to monitoring also follow a separate path. This allows the main outputs to remain assigned to hardware inserts and various external processing without interfering with the monitoring system.

Combining analog processing and native plug-ins

Conversion supports up to 32-bit / 192 kHz with a claimed dynamic range of 133 dB. Audient also specifies a round-trip latency of 0.99 ms at 192 kHz with a 64-sample buffer—a configuration designed for sessions that combine analog hardware and native processing.

This value corresponds to specific settings. The latency achieved in practice depends on the sample rate, buffer size, computer, and project load.

Add up to 16 digital channels

The dual ADAT connectors provide up to 16 additional digital input and output channels. They can accommodate ADAT converters, preamps, or other ADAT devices to expand the system without using the main analog connections.

BNC Word Clock inputs and outputs are also provided to synchronize the Horizon 32 with other digital devices in the studio. Selectable reference levels of +18 dBu or +24 dBu also facilitate its integration with various professional analog equipment.

Manage Routing with Horizon Control

Horizon Control combines routing, monitoring, and level display within the software. Its virtual patchbay makes it easy to assign different inputs and outputs when multiple external processors or monitoring paths need to coexist in the same session.

The software also includes a comfort reverb as well as monitoring controls such as Mono, polarity reversal, Dim, and reference level selection.

Expanding a System to Up to 200 Inputs and 200 Outputs

Up to four Horizon interfaces can be daisy-chained with a single macOS driver. A setup consisting of four Horizon 32 units can thus reach a maximum of 200 inputs and 200 outputs.

This architecture is primarily aimed at large studios, multi-room installations, and systems expected to grow over time. For a studio with fewer than 16 external analog channels, the Horizon 16 may be a more suitable choice: the Horizon 32 truly comes into its own when all 32 line inputs and 32 line outputs are utilized by a mixing console or a substantial setup of outboard gear.
