Audient Horizon 16

Audient Horizon 16 is a 1U Thunderbolt 3 audio interface and converter built around 16 channels of line I/O over four DB25 connectors, with 32-bit conversion at 133dB dynamic range. It delivers 34-in / 34-out connectivity, a dedicated stereo mix-bus path, and 0.99ms round-trip latency — built for the engineer keeping an entire outboard rack patched while printing straight to the DAW.

An outboard rack that stays patched

Sixteen channels of line I/O across four DB25 connectors keep a full rack of compressors, EQs and a summing bus permanently wired in, with no repatching between sessions. The dedicated stereo mix-bus input takes the return from a summing box and prints the master back to the DAW, so hybrid mixing never costs a single input channel.

Latency that never gets in the way of plugins

At 192kHz with a 64-sample buffer, round-trip latency sits at 0.99ms, so native plugins stay lag-free during monitoring. Horizon Control handles the virtual patch bay, monitoring and metering from a single panel, and the architecture scales by daisy-chaining up to four Horizon units on one driver, up to a system maximum of 200 x 200 I/O.

Who the Horizon 16 is for

For a rack full of compressors, EQs and a summing box that should stay patched in. The Horizon 16 gives you 32 analogue channels over four DB25 connectors and a dedicated stereo path for printing the mix, but it has no microphone preamps. For recording with microphones the Audient Horizon 8P is the better fit, and if you need twice the line channels, see the Audient Horizon 32.
