  • Expansion requires compatible ADAT outboard equipment

The Clarett+ 2Pre is a good fit when sound quality and compact dimensions matter more than a large native input count. Its ADAT port provides a clear upgrade path, while Air circuitry and JFET inputs add useful options for vocals and guitars.

How We Picked the Best Audio Interface with Adat Expansion

We focused on the capabilities that matter when building or upgrading a multichannel recording rig: ADAT input or output, available analog I/O, preamp count, conversion support, computer connectivity, monitoring features, and practical expandability. The list includes all-in-one USB interfaces as well as dedicated expanders that can add inputs to compatible hardware.

We also considered different studio sizes and budgets. A compact interface may suit overdubs and mobile work, while an 18- or 20-input model is better for full drum kits, rehearsals, and larger tracking sessions.

Quick Comparison

  • Best for a larger studio: Choose a high-I/O interface such as the Behringer UMC1820, Focusrite Scarlett 18i20, or Fender Quantum HD 2.
  • Best for adding more inputs: Dedicated expanders such as the Arturia AudioFuse X8 IN and Behringer ADA8200 can extend a compatible interface through ADAT.
  • Best for compact setups: The Scarlett 16i16, Scarlett 18i16, Clarett+ 2Pre, and similar USB-C models offer a balance of portability and expansion.
  • Best for simple recording: A basic 2×2 interface can work for vocals, guitar, and stereo sources, but check that it actually includes ADAT if future expansion is important.

Key Buying Factors for an Audio Interface with Adat Expansion

ADAT Channels and Sample Rate

ADAT commonly carries eight channels at standard sample rates, but the channel count can fall when using higher sample rates through S/MUX. Confirm whether the interface has ADAT input, output, or both, and check how many channels remain available at 96 kHz.

Analog Inputs and Preamps

Count the inputs you can use without expansion. Built-in mic preamps are useful for immediate recording, while line inputs give you flexibility with external preamps, mixers, and synthesizers. If you plan to add an expander, verify whether its output level and connection type match the main interface.

Connectivity and Monitoring

USB-C is common on newer interfaces, but connector type does not automatically determine speed or compatibility. Check operating-system support, driver stability, direct monitoring, headphone outputs, MIDI, and monitor-control features before buying.

Workflow and Room to Grow

Think beyond today’s channel count. A unit with reliable clocking, clear routing software, and enough ADAT capacity can remain useful as your microphone collection and recording projects grow.

Who Should Buy Which Audio Interface with Adat Expansion?

Choose a dedicated expander if you already own a compatible interface and mainly need additional microphone or line inputs. Choose a high-I/O interface if you want one central unit for bands, drums, or permanent studio wiring. Choose a compact USB-C interface if portability, vocal production, and occasional expansion matter most. If you are unsure, prioritize ADAT input, at least two headphone outputs, dependable drivers, and enough preamps for your next likely upgrade—not just your current setup.
