The Focusrite Scarlett 2i2 (4th Gen) wins this band outright: 69 dB of published mic gain is more than interfaces costing several times as much, and it removes the need for a booster entirely. The Audient EVO 4 is the pick if you keep getting levels wrong, thanks to Smartgain.
Under $200 you are not compromising on conversion in any way you will hear. What you are choosing between is gain ceiling, how good the drivers are, how many channels you get, and whether the manufacturer publishes enough for you to plan around.
The five value interfaces, ranked
Focusrite Scarlett 2i2 (4th Gen)
Top pickFocusrite · The most gain per dollar in a two-input box
The default answer for someone buying an SM7B or PodMic: it supplies enough clean gain that you never need a booster, which makes it the cheaper total purchase even when it is not the cheaper box. Look elsewhere only if you need MIDI or four outputs.
Why it is here
- 69 dB is the most gain of any interface at this price, and enough for an SM7B with headroom to spare
- 120 dB dynamic range means the converters are not the weak link
- Two inputs, so a second person does not mean a second purchase
What it costs you
- Air mode is a fixed voicing, not an EQ you can dial
- Plastic-and-metal build feels less solid than the SSL or Audient competition
- No MIDI, which matters if you also play keys
Audient EVO 4
Audient · Anyone who keeps getting gain-staging wrong
The pick for a second host on a budget, or for anyone whose recordings keep coming back too quiet. Not the pick if your mic is an SM7B, where the gain ceiling forces a booster.
Why it is here
- Smartgain removes the single most common beginner mistake in one button
- Two mic preamps at the price of most one-input boxes
- Genuinely small and bus-powered
What it costs you
- 58 dB again falls short of an SM7B's appetite
- Single encoder for everything means more button-pressing than knob-turning
- Plastic build
Audient iD4 MKII
Audient · The best-sounding single preamp here
The right box if your mic is a condenser or a hot dynamic and you want the cleanest single channel at this price. If you are buying an SM7B, 58 dB puts you straight back into booster territory.
Why it is here
- -129 dB(A) EIN and 0.0017% THD+N are numbers you would expect a tier up
- The Class A preamp is the same circuit family as Audient's consoles
- Two headphone outputs on a one-input box, which is unusual and useful
What it costs you
- 58 dB is not enough for an SM7B without a booster
- One mic input only
- No onboard DSP or voicing
Arturia MiniFuse 2
Arturia · Mic inputs plus MIDI in one small box
The right buy if you record voice and play keys and want one box for both. If voice is the only job and the mic is low-output, the gain ceiling makes it the wrong tool.
Why it is here
- MIDI I/O at this price is rare and saves a separate interface
- The USB passthrough port is a genuinely thoughtful touch on a crowded laptop
- Two combo inputs
What it costs you
- 56 dB is not SM7B territory
- 110 dB input dynamic range is the lowest here
- Bundle software is less useful than UA's
Behringer U-Phoria UMC204HD
Behringer · The floor of the category, honestly described
Buy it when the alternative is not recording at all, and plan to replace it. With no published gain figure it is a gamble with any low-output dynamic — pair it with a hot mic or not at all.
Why it is here
- Cheapest two-input interface worth plugging a real mic into
- Two combo inputs and phantom power at a price nothing else matches
- Inserts on the inputs, which is unusual this low
What it costs you
- Behringer does not publish a maximum gain figure, so you cannot plan a gain budget from the spec sheet
- Driver experience is the weakest in this group
- Build reflects the price
What we did not pick, and why
- Single-input interfaces below the iD4's quality. A one-input box is a ceiling you will hit the first time someone joins you, and the saving over a two-input interface is small.
- USB interfaces with no phantom power. They rule out every condenser and every inline booster, which is most of the reason to own an interface.
- Interfaces bundled with a microphone at a headline price. The bundled microphone is almost always the cheapest item the manufacturer could include, and you will replace it. Buy the interface and choose the microphone separately.
- Anything that publishes no specifications. Cheap is not the problem; unverifiable is. We will not rank on a figure we cannot cite.
Pair it with
- A microphone that does not need `60 dB`. The Rode PodMic or the BP40 are the sensible pairings at this price.
- Or the cheapest booster, if you have already bought the mic. Best preamps for the SM7B.
- One decent cable. Best XLR cables.
How to choose
- If your microphone is a low-output dynamic, buy the Scarlett 2i2 and stop reading. 69 dB solves the only problem at this price point.
- If you keep recording things too quietly, the EVO 4's Smartgain is worth more than a few dB of ceiling.
- If you also play keys, the MiniFuse 2's MIDI saves a second purchase.
- If you want the cleanest single channel and only need one, the iD4 MKII's -129 dB(A) EIN is a tier above the rest here.
- Only take the UMC204HD if the alternative is not recording at all, and expect to replace it.
