Audient EVO 8 Specs: Inputs, Preamps and Sample Rate
The Audient EVO 8 is a $150 to $300 desktop interface with 4 microphone preamps, 4 analogue inputs and 4 analogue outputs, connecting over USB-C at up to 96 kHz. Four preamps, bus powered, with Smartgain across all four. The cheapest honest four-preamp interface.
Definition: A microphone preamp is the amplifier stage that raises a microphone's very low output to line level, and the number of them is how many XLR microphones an interface can record simultaneously with phantom power.

What is the Audient EVO 8 good at?
Four bus-powered preamps for the price competitors charge for two.
In practical terms, 4 microphone preamps is the number that decides what you can record at once, and it is the number most worth reading carefully. Manufacturers routinely advertise a total input count that includes line inputs you cannot plug a microphone into and digital channels you cannot use without buying another box. The specification table above counts physical analogue jacks and preamps separately for exactly that reason.
It runs on bus power, so a laptop and a cable is the whole rig. There are no MIDI ports, so a hardware synth or an older controller needs a separate USB path.
What is it not good at?
No MIDI, no ADAT, so four is where the channel count stops permanently.
Every interface trades something. The useful question is not whether a box has a weakness but whether its weakness lands on something you will actually do. A missing MIDI port is irrelevant if you never touch hardware synths and a permanent annoyance if you do. A 96 kHz ceiling is a non-issue for almost every music recording and a hard stop for a small number of specialist workflows. Match the limitation to your own work rather than to a specification comparison.
What else has 4 microphone preamps?
These are the direct alternatives by the number that matters most, rather than by price. Two interfaces with the same preamp count are solving the same problem, and the differences between them are in the driver, the gain available and what else is on the back panel.
| Interface | Preamps | In / Out | Connection | Max rate | Price band |
|---|---|---|---|---|---|
| Audient EVO 8 | 4 | 4 / 4 | USB-C | 96 kHz | $150 to $300 |
| Universal Audio Volt 476 | 4 | 4 / 4 | USB-C | 192 kHz | $300 to $700 |
| Solid State Logic SSL 12 | 4 | 6 / 8 | USB-C | 192 kHz | $300 to $700 |
| Steinberg UR44C | 4 | 6 / 4 | USB-C (USB 3.0) | 192 kHz | $300 to $700 |
How much latency will it give you?
The interface itself contributes a fixed overhead, and the buffer setting contributes the rest. Latency in milliseconds is buffer samples / sample rate x 1000, so a 128 sample buffer at 44.1 kHz is 2.90 ms one way and about 5.80 ms round trip before the hardware is counted. A USB-C interface typically adds another 2 to 6 ms of converter and driver delay on top, which is the part that varies between manufacturers at the same buffer setting.
Work out your own figure with the latency buffer calculator, and check the full conversion grid on the sample rate and latency chart. If you are choosing between this and a Thunderbolt unit, the USB versus Thunderbolt comparison covers where the difference is real and where it is marketing.
Will it drive the microphone you want?
Gain is the specification that decides this and it is not on most product pages. A large diaphragm condenser needs roughly 40 dB for a sung vocal at six inches, which every interface here supplies comfortably. A low-output dynamic like the Shure SM7B needs closer to 60 dB, and that is where budget preamps run out and you start hearing hiss before you reach a usable level.
Check your own combination against the gain staging calculator before ordering either the interface or the microphone. If the figure comes up short, an inline booster adds about 25 dB of clean gain at the microphone end for far less than an interface upgrade.

Frequently asked questions
How many microphones can you plug into the Audient EVO 8?
4. The Audient EVO 8 has 4 microphone preamps, which is the number of XLR microphones you can record simultaneously with phantom power. Manufacturers often advertise a higher total input count by including line inputs and digital channels, so read the preamp figure rather than the headline number. Its 4 analogue inputs include the preamp channels.
Does the Audient EVO 8 have enough gain for a dynamic microphone?
A low-output dynamic like an SM7B needs roughly 60 dB of clean gain for a normal speaking voice at close range, and many interfaces in the budget and mid bands stop short of that. If you plan to use one, check the published maximum gain figure, and budget for an inline booster if it falls short. A booster adds around 25 dB of clean gain right at the microphone, which lowers noise as well as raising level.
What latency can you expect from the Audient EVO 8?
Latency depends on your buffer setting rather than the interface, and the interface contributes a fixed overhead on top. At a 128 sample buffer and 44.1 kHz the buffer alone is 2.90 ms one way and 5.80 ms round trip, and a typical USB-C interface adds another 2 to 6 ms of converter and driver delay. Driver quality is what separates units at the same buffer setting.
Is the Audient EVO 8 good for a beginner?
Yes. At $150 to $300 it sits in the band where a first interface makes sense, and 4 microphone preamps covers the common case of one voice or one voice plus one instrument. It runs on bus power, so a laptop and a cable is the whole rig. The thing to check before ordering is whether the preamp gain suits the microphone you intend to buy.
Does the Audient EVO 8 need a separate power supply?
No. It runs on bus power over its USB-C connection, so a laptop and one cable is the entire rig. Bus power is worth more than it sounds if you ever record away from the desk, because it removes both a cable and a hunt for an outlet from every session.
What is the Audient EVO 8 not good at?
No MIDI, no ADAT, so four is where the channel count stops permanently. That is a genuine limitation rather than a nitpick, and it is worth checking against what you actually intend to record before ordering. Every interface makes a tradeoff somewhere, and knowing where this one made its tradeoff is more useful than a specification you will never test.
