Best Two-XLR Audio Interfaces for Co-Hosted Podcasts
For a co-hosted show recorded in one room, the Focusrite Scarlett 2i2 (4th gen, ~$190) is the safest two-XLR pick: two clean preamps, per-channel gain, and the easiest auto-level button of the three. The MOTU M2 (~$200) wins on metering and headphone-amp quality; the Universal Audio Volt 2 (~$169) is the cheapest and adds a likable analog "vintage" preamp voice. One catch links all three: each has only one headphone jack. For two people listening live, that changes the math, and it's the thing most buyers learn the hard way.
That single detail is the reason this list is three names long instead of fifteen. If you want one box that takes two real microphones and gives each host their own headphones, the answer is a different product entirely, and I'll name it below. First, the three interfaces that actually fit the search you typed.
What an interface with two XLR inputs has to do
An audio interface is the bridge between an XLR microphone and your computer: it powers the mic, boosts the signal with a preamp, converts it to digital, and routes monitoring back to your headphones. For a co-hosted podcast, "two XLR inputs" is the floor. Above it, four things decide whether the box is good for two people, not just two channels:
- Per-channel gain, a separate level knob for each mic, so a quiet guest and a loud host don't fight over one setting.
- Per-channel or shared phantom power, the +48V that condenser mics need; on small interfaces it's often one switch for both inputs.
- Headphone monitoring, how many people can actually hear themselves while recording.
- Input metering, whether you can see each mic clipping before it ruins a take.
Mics matter more than the interface for raw sound quality, and a dynamic mic in an untreated room beats a fancy preamp every time. If you haven't locked your mic choice yet, start with our podcast mic picks by budget tier and the case for XLR over USB once a second person joins. This piece assumes you've decided on XLR and need the box behind it.
The three picks, compared
Here is the short version. The detail, and the one shared limitation, follows.
| Interface | Best for | The catch |
|---|---|---|
| Focusrite Scarlett 2i2 (~$190) | Easiest setup, best auto-gain | One headphone jack; phantom power is both-or-neither |
| MOTU M2 (~$200) | Best metering + headphone amp | One headphone jack; no auto-gain |
| Universal Audio Volt 2 (~$169) | Cheapest, analog preamp character | One headphone jack; one phantom switch for both |
Prices: Scarlett 2i2 4th gen and MOTU M2 from Sweetwater product pages; Volt 2 street price from Universal Audio and retailer listings, all mid-2026.
1. Focusrite Scarlett 2i2 (4th gen), the default
Best for: a first co-hosted rig where you want the fewest decisions.
The 4th-gen Scarlett 2i2 has two mic preamps with a 69 dB gain range and a separate gain knob per channel, so you can set a soft-spoken guest and a projecting host independently (Focusrite). Its real edge for beginners is Auto Gain: hit the button, talk for ten seconds, and it sets a sane level for each mic on its own. Clip Safe then rides the gain down if you're about to distort. For two people who don't want to learn gain staging on day one, that's genuinely useful.
One price note: Focusrite's list price is $224.99, and the ~$190 figure I'm using is the current sale price at Focusrite and Sweetwater (mid-2026 promos). At full list it's actually the priciest of the three, so buy it on a discount, which is its usual state.
The pros: clean preamps, two "Air" modes (Focusrite now labels them Presence and Harmonic Drive) that add brightness or a little drive for dull voices, and the most forgiving onboarding of the three.
The con worth naming: phantom power is a single 48V button for both XLR inputs, you can't run a condenser on one channel and switch the other off (Focusrite hardware features). For a podcast where both hosts use the same kind of mic, that's a non-issue. Mixing a phantom-hungry condenser with a ribbon mic that hates phantom is where it bites. And, like every interface on this list, it has one headphone output.
2. MOTU M2, the one you see your levels on
Best for: hosts who want to watch both mics and trust their headphones.
The M2 gives you two combo XLR/TRS inputs with independent gain and independent 48V per channel, which is the flexibility the Scarlett gives up (MOTU specs). Its standout is the full-color LCD with real metering for both inputs, you see each host's level and clipping at a glance, not a vague halo. MOTU also puts its ESS Sabre32 converter on the headphone output, and the headphone amp is noticeably stronger than its price suggests.
The pros: the only screen-based metering of the three, per-channel phantom, and a headphone output that drives demanding cans cleanly.
The cons: no auto-gain, so you set levels manually (easy with that meter, but a step the Scarlett automates). Some retail boxes ship without a USB-C cable, check your bundle. Maximum preamp gain is around 60 dB, lower than the Scarlett's 69 dB; fine for most dynamic mics at a normal distance, tighter if you pair a low-output mic like an SM7B with a quiet speaker. And again, one headphone jack.
3. Universal Audio Volt 2, the cheapest with character
Best for: the smallest budget, or a host who wants a warmer preamp sound out of the box.
The Volt 2 is usually the least expensive here at roughly $169 street, with two combo inputs and a dedicated gain knob per channel (Universal Audio). Its signature is Vintage mode, a switchable preamp voicing that emulates UA's classic 610 tube preamp, a subtle, pleasant thickening that flatters spoken voice without a plugin. Mic-preamp gain tops out at 55 dB (UA Volt specifications), the lowest of the three, so a low-output dynamic like the SM7B pushes it harder than the Scarlett would.
The pros: lowest price, a likable analog character, and solid build from a respected preamp company.
The cons: phantom power is a single switch applied to both inputs, same constraint as the Scarlett (Volt 2 manual). No auto-gain. Metering is simple LED indicators rather than a screen. And, you know the line by now, one headphone output.
The catch nobody mentions: two people, one headphone jack
All three of these interfaces have exactly one headphone output. That's fine for a solo host. For two people in the same room, it means only one of you can monitor, and the person who can't hear themselves drifts off-mic, talks over the other, and pops plosives they'd have caught.
There are two honest fixes, and neither requires buying a bigger interface.
Fix 1, a headphone amp or splitter ($25–$35). A small four-output headphone amp takes the single headphone signal and splits it to several pairs, each with its own volume knob. Both hosts hear the same mix. For the vast majority of two-person shows recording in one room, this is all you need, and it keeps whichever interface you preferred above.
Fix 2, buy an interface built for two listeners. Two products solve this in hardware:
- Focusrite Vocaster Two (~$250), purpose-built for podcasting, with labeled Host and Guest XLR inputs, two headphone outputs, around 70 dB of gain, one-button Auto Gain, and Bluetooth to pull in a phone caller (Focusrite). If your show is two people and you never plan to record music, this is the most frictionless box on the page.
- SSL 2+ MkII (~$300), two headphone outputs with independent amps and independent source routing, so each person can hear a different mix (Sweetwater). Overkill for a simple chat show; the right call if you also record instruments or want a remote guest on a separate mix.
The honest decision rule: if both hosts are happy hearing the same thing, keep the cheaper interface and add a $30 splitter. If you want the cleanest single-box experience and the budget stretches, the Vocaster Two is the dedicated answer.
How I picked these three
I scoped this to the exact job: two real XLR microphones recorded at once into one bus-powered box you can buy today for under ~$200. That rules out single-input interfaces, four-input mixers you don't need yet, and dedicated podcast consoles like the Rodecaster, which are a different (larger, pricier) category.
Within that scope I weighted four things for two people specifically: independent per-channel gain, phantom-power flexibility, monitoring (both how many can listen and how well), and visible metering so neither host clips a take. Pricing is verified against retailer pages from mid-2026 and noted as approximate because interface prices move with promotions. Where a spec is a manufacturer claim (gain range, converter), I've attributed it to that manufacturer's page rather than presenting it as independently tested.
The verdict
Buy the Scarlett 2i2 if you want the least fuss and the auto-gain safety net, it's the right default for most first co-hosted shows. Buy the MOTU M2 if seeing your levels and a stronger headphone amp matter more than auto-leveling. Buy the Volt 2 to save money or for its analog preamp warmth. Then, whichever you choose, add a $30 headphone amp so both hosts can hear, or, if you want it solved in one box, step up to the Vocaster Two.
The interface is the boring, reliable middle of your chain. Once it's recording two clean tracks, the next decision is your mic, covered in the budget-tier mic guide and the under-$100 picks, and how you structure the conversation, which is where a repeatable episode structure and a clear call on scripting versus outlining do more for listener retention than any preamp.
FAQ
Do I need an audio interface if I use USB mics? No. A USB microphone has the interface built in and plugs straight into your computer. The catch is that most computers struggle to run two USB mics cleanly at once, which is exactly why co-hosted shows move to XLR mics plus a two-input interface. See our USB vs XLR breakdown for when the switch is worth it.
Can two people use one headphone output? Only with help. Out of the box, the Scarlett 2i2, MOTU M2, and Volt 2 each have one headphone jack. Add a small headphone amp or splitter (about $25–$35) and both hosts hear the same mix with separate volume, the cheapest fix by far.
What if my mics need different gain? All three interfaces have a separate gain knob per channel, so a quiet guest and a loud host can each be set correctly. The Scarlett 2i2 also has Auto Gain that sets each level for you after a ten-second talk test.
Is the Vocaster Two better than these for podcasting? For a two-person talk show, often yes, it has two headphone outputs, labeled Host and Guest inputs, around 70 dB of gain, and Auto Gain, all aimed at podcasting (Focusrite). It costs more (~$250) and isn't built for music recording. If you only ever record voices with a co-host, it removes the most steps.
Will a better interface make my podcast sound better? Marginally. Past this price band, the gap between interfaces is small. Your mic, your mic technique, and your room matter far more, a dynamic mic used close in a quiet room beats any preamp upgrade in a noisy one.
