Budget ADAT Preamp Expander – Behringer ADA8200
Behringer ADA8200 Audiophile 8 In/8 Out ADAT Audio Interface with Midas Mic Preamplifiers
Check Price On AmazonThe ADA8200 is a straightforward audio interface with ADAT expansion for adding eight extra microphone channels to a compatible setup. It uses Midas mic preamps and 24-bit conversion at 44.1/48kHz, making it a practical way to expand inputs without overcomplicating your rig.
Best For: Studios that need an affordable eight-channel ADAT expander for extra mic inputs.
Pros:
- 8-channel microphone preamp section for added input capacity
- ADAT optical out for expansion into a larger system
- Midas preamps add a higher-end touch for the price class
- Simple wired design keeps integration straightforward
Cons:
- Limited to 44.1/48kHz operation

How We Picked the Best Audio Interface with ADAT Expansion
We focused on interfaces that make ADAT expansion genuinely useful: stable drivers, enough native I/O to serve as a main hub, and expansion options that can scale a home or project studio. We also prioritized practical features such as low-noise mic preamps, MIDI support where relevant, monitor control, and input layouts that suit real-world recording.
Quick Comparison
The best choice depends on your workflow. Larger desktop interfaces are ideal if you want a central recording hub with room for direct tracking. Expansion units are best when you already have a main interface and need more mic inputs. Premium models appeal to users who want top-tier conversion and monitoring tools, while value picks are better for straightforward multitrack recording on a budget.
Key Buying Factors for an Audio Interface with ADAT Expansion
ADAT channel count: Check how many channels the interface can send and receive over optical ADAT, and confirm the sample-rate limits. Some systems support eight channels at standard rates, with reduced counts at higher sample rates.
Native I/O: ADAT is only part of the story. Make sure the interface has enough local inputs and outputs for your core workflow, especially if you record drums, bands, or multiple microphones at once.
Preamps and conversion: Your expansion chain is only as good as the weakest link. Look for quiet preamps, solid gain range, and reliable converters if you care about detail and headroom.
Connectivity and software: USB-C, Thunderbolt, MIDI, and monitor-control features can affect daily convenience. Good control software matters too, especially when routing is involved.
Future growth: Choose an interface that can act as a long-term hub. If you expect to add outboard pres, extra headphone mixes, or digital gear later, make sure the interface architecture can support it.
Who Should Buy Which Audio Interface with ADAT Expansion?
If you’re building a small studio and want an easy path to more channels, choose a midrange desktop interface with ADAT built in. If you already own a solid interface and only need more mic inputs, an ADAT expander is the most cost-effective upgrade. If you’re running higher-end production or need advanced monitoring and conversion, a premium Audio Interface with ADAT Expansion can be worth the extra spend. For simple vocal, guitar, or podcast setups, a smaller interface may be enough unless you know you’ll expand soon.
In short, the right choice depends on whether you need a compact starter unit, a scalable central hub, or a dedicated expansion stage. Match the interface to your current input needs first, then leave headroom for the sessions you expect next year.
