audient Horizon 8P (Audio Interface) (Thunderbolt 3)

24-input/32-output Thunderbolt 3 audio interface

The Horizon 8P is a 24-in/32-out Thunderbolt 3 audio interface centered around eight Audient console microphone preamps with ORBIT Control variable impedance functionality.
Combined with 32-bit conversion featuring a 133dB dynamic range and 0.99ms round-trip latency, the 8P condenses a complete, console-grade recording front-end into a single rack unit. This product is designed for producers and studios that want to capture performance with true analog texture and headroom.

*Measured at 192kHz/Buffer Size: 64 samples

◆Main Features

8 Audient console microphone preamplifiers
Variable impedance via ORBIT Control
24 inputs / 32 outputs
32-bit/192kHz compatible
133dB dynamic range
0.99ms round-trip latency (192kHz/64sample)
Horizon Control software allows you to daisy-chain up to four Horizon series consoles.

◆Reasons for choosing HORIZON 8P

The Horizon 8P packs a complete recording front-end setup into a single 1U rack. Inheriting the David Dearden-designed circuitry from the ASP8024-HE console, eight professional Audient console preamps deliver analog character and 75dB of clean, low-noise gain to any sound source. ORBITControl allows you to change the impedance of each preamp in hardware, shaping the tone of ribbon, dynamic, and condenser microphones at the input stage.

For mixing, you can directly connect outboard gear to the DB25's eight line inputs. With 32-bit conversion offering a 133dB dynamic range and 0.99ms round-trip latency, you can record and monitor through native plugins without any noticeable delay. Horizon Control provides one-click access to routing, monitoring, and four cue mixes.

◆From a DSP-centric production environment to a more flexible native environment

The Horizon 8P achieves a round-trip latency of 0.99ms when set to 192kHz/64 samples.

Recording vocals with compression and EQ applied. Playing with a sound processed through a guitar amp simulator. Layering software instruments and live performances with the same sense of timing. Even in these situations, it provides a response that minimizes the performer's awareness of delay.

This system allows you to build a recording system centered around your preferred DAW and native plugins, without being tied to a specific DAW and DSP environment. It enables you to create a low-latency recording environment without limiting your production tool choices.

◆Scalable system configuration with up to 4 units

The Horizon series allows you to daisy-chain up to four units on a single driver.
The entire system supports a maximum of 200x200 I/O. *When using 4 Horizon32 units.

From small private studios to production environments with multiple booths, the system can be assembled according to the number of inputs and outputs required.
