Overview

The Audient EVO SP8 is an eight-channel microphone preamplifier and AD/DA converter designed to expand the input capacity of your existing recording setup. Each of its eight preamps features Audient's Smartgain technology, which automatically listens to incoming signals and sets gain levels to an optimal recording threshold—a significant time-saver when miking a full drum kit or ensemble. The 32-bit AD/DA conversion ensures that the audio captured through the EVO SP8 retains exceptional detail and dynamic range, delivering the kind of fidelity typically associated with higher-priced units.

Connectivity centers on dual ADAT optical outputs, making the EVO SP8 compatible with any audio interface that has ADAT inputs. The eight mic/line inputs accept both microphone and line-level sources, while eight dedicated line outputs provide routing flexibility for monitor mixes, outboard effects, or other signal paths. The Motion UI control system condenses what would normally be a panel full of knobs into a single smart encoder that adapts to the selected channel and function, keeping the interface clean and approachable. For home studios, project rooms, or professional facilities that need additional high-quality preamps without replacing their primary interface, the EVO SP8 offers a compelling and cost-effective expansion path.

Pros & Cons

👍 Pros

  • Eight mic preamps with Smartgain auto-leveling simplify multi-channel recording setup
  • 32-bit AD/DA converters provide high-resolution audio capture and playback
  • Dual ADAT outputs allow integration with virtually any ADAT-equipped audio interface
  • Motion UI single-knob control system keeps the unit intuitive despite its channel count
  • Eight line outputs add flexible routing for monitor mixes or outboard processing

👎 Cons

  • Requires a host interface with ADAT input—cannot function as a standalone audio interface
  • ADAT channel count reduces at higher sample rates due to the optical protocol's bandwidth limits
  • No built-in headphone output for direct monitoring from the unit itself
  • Phantom power and preamp controls depend on the Motion UI system, which has a learning curve

Frequently Asked Questions

It connects via ADAT optical, so your primary interface needs an ADAT input to receive the eight additional channels from the EVO SP8.
Smartgain is Audient's automatic gain-setting feature. It listens to your input signal and sets the preamp level to an optimal recording level, which is especially useful when setting up multiple microphones simultaneously across all eight channels.
No, the EVO SP8 is a preamp expansion unit. It requires a host audio interface with ADAT input to pass its audio channels into your DAW.
The Motion UI system uses a single smart encoder knob that adapts its function based on context, allowing you to control gain, headphone volume, and other parameters without cluttered multi-knob layouts.
The EVO SP8 features 32-bit AD/DA conversion. Via dual ADAT connections, it can deliver all eight channels at standard sample rates, with channel count reducing at higher rates as per the ADAT specification.
