The Ruling
Neither one leads on more of the chart than the other: the Mackie Onyx Artist 1x2 takes Audio Resolution, the Audio-Technica AT-UMX3 Desktop Mixer takes Creator Features. With the trade even, $99.05 is the tiebreaker, and the Mackie Onyx Artist 1x2 is the cheaper side of it.

At a Glance
Every axis is scored out of 10 from the catalog specs below. The scores are relative to the products on this page, so a 10 means “best of these”, not “perfect”, and two identical columns mean the catalog genuinely cannot separate them. Axes the catalog holds no figure for on both sides are left off entirely rather than guessed at.
| Category | Mackie Onyx Artist 1x2 | Audio-Technica AT-UMX3 Desktop Mixer |
|---|---|---|
| Audio Resolution | 10/10 | 6.3/10 |
| Mic Inputs | 10/10 | 10/10 |
| Monitoring | 10/10 | 10/10 |
| Creator Features | 5/10 | 10/10 |
| Power | 10/10 | 10/10 |
| Value | 10/10 | 3.8/10 |
The Split
Desktop audio interface intended for creator workflows, microphone input, monitoring, and clean signal routing.
On paper the Mackie Onyx Artist 1x2 takes sample rate (192kHz, +144kHz). It gives up loopback to the Audio-Technica AT-UMX3 Desktop Mixer. It is the cheaper of the two, by $99.05.
Leads on
Higher sample rates capture more audio detail — important for professional recording and mixing.
Compact desktop streaming mixer/interface with tactile controls for mic and monitor balancing.
On paper the Audio-Technica AT-UMX3 Desktop Mixer takes loopback (Yes). It gives up sample rate to the Mackie Onyx Artist 1x2. That costs $99.05 more than the Mackie Onyx Artist 1x2.
Leads on
Loopback routes computer audio back into the stream without a second interface or cable.
These 9 specs are the same on both of them, so none of it is part of the decision.
The Record
A group is won by whoever takes more of its rows outright. Specs the catalog cannot rank are shown but never decide a group.
Bottom Line
The Mackie Onyx Artist 1x2 is the pick on the specs the catalog holds, but “better on paper” and “right for you” are different questions. Each case below names what the product is actually good at and who that suits.
The clearest difference is loopback, which the Audio-Technica AT-UMX3 Desktop Mixer has and the Mackie Onyx Artist 1x2 does not. Across the catalog's specification sheet the two differ on 2 specs. They match on 9 specs, including connection type, bit depth and phantom power. Two audio interfaces from Mackie and Audio-Technica, each taking a different approach to audio quality and I/O flexibility.
It is a toss-up — take the Mackie Onyx Artist 1x2. Neither one leads on more of the chart than the other: the Mackie Onyx Artist 1x2 takes Audio Resolution, the Audio-Technica AT-UMX3 Desktop Mixer takes Creator Features. With the trade even, $99.05 is the tiebreaker, and the Mackie Onyx Artist 1x2 is the cheaper side of it.
Both share 9 specifications in the catalog, including connection type (usb-c, xlr, trs), bit depth (24-bit), phantom power (Yes) and XLR inputs (1), among others. None of those is a reason to pick one over the other.
The Audio-Technica AT-UMX3 Desktop Mixer costs $159.00 against $59.95, a difference of $99. The premium buys loopback (Yes). Whether that is worth it depends on which of those you would actually use.
