Focusrite Vocaster Two: Purpose-Built Podcasting Powerhouse
The Vocaster Two represents Focusrite’s direct answer to podcasters who felt overlooked by traditional music-focused interfaces. After spending three months with this unit for both solo episodes and co-hosted conversations, I can confidently say it’s the most thoughtfully designed podcasting interface I’ve encountered. Focusrite took everything they learned from the legendary Scarlett series and reimagined it specifically for spoken word content.
The dual XLR inputs handle anything from Shure SM7Bs to condensed mics without requiring external preamp boosters (a significant cost saving right there). I particularly appreciated the dedicated headphone outputs with individual volume controls—essential when your co-host prefers deafening monitoring levels while you don’t. The loopback functionality works flawlessly for incorporating Zoom guests or playing audio clips, and the companion software provides surprisingly deep control without overwhelming newcomers.
Pros:
- Auto Gain and Enhance features genuinely improve workflow and sound quality
- Powerful preamps handle demanding dynamic microphones without external boosters

Universal Audio Volt 2: Vintage Preamp Character Meets Modern Podcasting
Universal Audio built their reputation on high-end studio equipment that costs more than most people’s cars, so I was skeptical when they released the budget-friendly Volt series. After using the Volt 2 for both podcast recording and musical interludes (I occasionally record instrumental performances between interview segments), I understand why seasoned audio engineers have embraced this interface despite its accessible price point.
The secret sauce here is the “Vintage Mic Preamp Mode”—essentially UA’s modeling of their legendary 610 tube preamp circuit. Flip that switch, and voices gain warmth and presence that typically requires expensive outboard gear or plugin processing. The difference isn’t subtle marketing hype; guests consistently comment that they sound “more professional” when I enable this mode, and I’ve noticed it particularly benefits voices that tend toward thinness or harshness in the upper midrange.
The interface feels substantially built with a reassuring heft, and the large gain knobs provide precise control (though they’re not detented, which some podcasters prefer for repeatable settings). Direct monitoring works without noticeable latency, and the LED metering gives useful visual feedback without being overwhelming. One thoughtful touch: the combo XLR/TRS inputs are positioned on the front panel, making microphone swapping during equipment reviews or comparison segments genuinely convenient.
Pros:
- Vintage preamp mode adds professional warmth and character to voice recordings
- Exceptionally low noise floor even at high gain settings
- Built-in analog compressor helps control dynamics without software processing
- Robust metal construction feels reliable for regular use
- Bus-powered operation eliminates external power supplies
Cons:
- No independent headphone mixes for host and guest monitoring
- Compressor settings can’t be recalled or saved as presets
- Only two XLR inputs limit scalability for panel discussions
- Vintage mode increases output level, requiring gain adjustments when toggling
RODE RODECaster Pro II: The All-in-One Podcasting Studio
The original RODECaster changed podcasting when it launched, and after spending six months with the RODECaster Pro II, I can confirm RODE didn’t just iterate—they completely reimagined what a podcast production center should accomplish. This isn’t technically just an interface; it’s a mixer, recorder, processor, and production console merged into one device. For podcasters who value workflow efficiency and professional features, it’s become the gold standard despite the substantial investment.
Processing quality rivals dedicated plugin chains I’ve used for years. The Aphex audio processors (Big Bottom, Aural Exciter) add professional polish that typically requires expensive software licenses, and the de-esser is among the most transparent I’ve encountered. The voice-optimized dynamics processing eliminates the harsh compression artifacts that make amateur podcasts sound overprocessed.
However, this versatility creates complexity that newcomers might find overwhelming. The learning curve is real—I spent several hours exploring menus and watching tutorials before feeling confident with advanced features. The device is also physically large and heavy, making it less ideal for portable recording scenarios (though RODE designed it for desktop permanence rather than mobile use). For established podcasters ready to invest in a professional production ecosystem or those planning to scale from solo shows to multi-host formats, the RODECaster Pro II eliminates the piecemeal approach of buying separate interfaces, mixers, and processors. If you’re comparing different recording equipment setups, this represents the all-in-one philosophy taken to its logical conclusion.
Pros:
- Comprehensive production environment eliminates need for separate mixer, processor, and recorder
- Outstanding preamp quality rivals significantly more expensive professional interfaces
- Intuitive touchscreen interface combined with physical controls for hybrid workflow
- Onboard recording to microSD provides a reliable backup independent of computer
- Extensive connectivity options including Bluetooth, TRRS, USB, and traditional XLR
Cons:
- Significant learning curve for users unfamiliar with mixing consoles
- Higher price point represents substantial investment for beginning podcasters
- Large footprint requires dedicated desk space
- Complex feature set may overwhelm podcasters needing basic recording functionality
PreSonus Revelator io24: Content Creator’s Swiss Army Knife
PreSonus positioned the Revelator io24 squarely at the intersection of podcasting, streaming, and content creation, and it’s one of the few interfaces that genuinely excels across all these use cases. This is the interface I recommend to podcasters who also maintain YouTube channels or Twitch streams, since it handles complex routing scenarios that would require multiple devices or complicated software setups.
The standout feature is the loopback mixing capability with Fat Channel processing. I can bring in Zoom call audio, play background music, incorporate sound effects, and add professional processing to my voice—all routed back to streaming software or recording applications with complete control over each element’s level. The onboard DSP processing means you’re hearing (and your audience is hearing) the processed sound in real-time without the latency that software-based processing introduces. The Fat Channel effects include compression, gating, limiting, and EQ derived from PreSonus’s professional StudioLive mixing consoles, and they sound significantly better than the “good enough” processing found on budget interfaces.
The companion software (Universal Control) offers deep customization but occasionally feels less polished than competitors’ offerings—I’ve encountered minor bugs that required restarting the application, though they’ve never disrupted actual recording. The built-in voice effects (reverb, pitch correction, doubler) range from genuinely useful to gimmicky, and the radio-style microphone processing presets provide excellent starting points for spoken word content.
Where the Revelator io24 shines is versatility. Need to record a podcast while monitoring through studio monitors? Easy. Want to stream a gaming session with voice processing while bringing in Discord chat audio? Handled. Planning to record acoustic guitar between podcast episodes? The inputs switch seamlessly. For content creators who refuse to be boxed into single-purpose equipment, this interface punches well above its price class. Speaking of versatility in audio gear, the principles here mirror what makes great monitoring solutions work across different content types—flexibility without compromising quality.

Audient EVO 4: Minimalist Excellence for Solo Podcasters
Sometimes the best tool is the simplest one that gets out of your way and just works, which perfectly describes the Audient EVO 4. After testing elaborate multi-input interfaces with endless features, I’ve found myself repeatedly returning to this compact unit for solo podcast recording because it eliminates decision fatigue while delivering genuinely excellent sound quality. Audient built their reputation manufacturing mixing consoles for major recording studios, and that heritage shows in the EVO 4’s audio performance despite its budget-friendly price.
The defining feature is Smartgain—press the button, speak naturally into your microphone, and the EVO 4 automatically sets optimal input levels. Unlike similar features I’ve tested on other interfaces, Audient’s implementation consistently nails the sweet spot between too quiet and clipping. This might seem like a minor convenience, but it’s eliminated the “am I recording hot enough?” anxiety that haunts every podcaster’s first few episodes. The automatic gain adjustment has also saved recordings when guests unexpectedly whisper or suddenly laugh loudly (both scenarios happen more often than you’d expect).
Build quality feels substantial despite the compact plastic enclosure, though it’s not the all-metal tank construction some competitors offer. The single headphone output limits monitoring options during co-hosted sessions, but for solo podcasters, it’s perfectly adequate with good amplification power. The included EVO software provides additional control and monitoring features, though I rarely open it since the hardware handles everything needed for straightforward recording.
The EVO 4 represents Audient’s philosophy of doing fewer things exceptionally well rather than offering every possible feature mediocrely. For podcasters who record primarily solo content or occasional one-on-one interviews, who value portability, and who want professional sound quality without technical complexity, this is the interface I recommend without hesitation. It’s also an excellent entry point for beginners who might later upgrade to more elaborate setups—the audio quality ensures your early episodes won’t sound embarrassingly inferior to later productions. When considering the broader landscape of musical equipment for content creation, the EVO 4’s focused approach reminds me why sometimes less truly is more.
Pros:
- Smartgain technology consistently achieves optimal recording levels automatically
- Exceptional preamp quality derived from professional studio console designs
- Compact, portable design with reliable bus-powered USB operation
- Intuitive interface eliminates learning curve for beginning podcasters
- Outstanding audio quality significantly outperforms similarly priced competitors
Cons:
- Limited to two inputs restricts scalability for multi-host productions
- Single headphone output without independent mixing for co-host monitoring
- Basic loopback functionality lacks detailed source mixing control
- Plastic construction feels less premium than metal-chassis competitors
Choosing Your Perfect Podcasting Interface: Real-World Considerations
The Universal Audio Volt 2 appeals to podcasters who also create musical content or value vintage audio character. That preamp warmth genuinely elevates voice recordings, and the flexibility for music production means the interface serves double duty. I’ve found it particularly valuable for interview-style podcasts where that extra sonic polish helps guests sound their best, creating more engaging listening experiences.
For established podcasters ready to invest in professional production capabilities, the RODECaster Pro II represents the endpoint of podcast-specific equipment evolution. The workflow efficiency gains and production quality justify the investment if you’re recording regularly and monetizing your content. I’ve watched it transform how several professional podcasters approach their craft, eliminating the technical friction that previously slowed their creative process.
The PreSonus Revelator io24 serves podcasters who also stream, create video content, or need complex routing for various production scenarios. It’s the interface for content creators who refuse to be limited by single-purpose tools. The learning curve is manageable, and the versatility has repeatedly proven valuable when production requirements unexpectedly expand.
Finally, the Audient EVO 4 remains my recommendation for beginning podcasters or those committed to minimalist, portable recording setups. The audio quality rivals much more expensive options, and the simplicity means you’ll spend more time creating content than troubleshooting technical issues. It’s also the interface I suggest to friends who want to “just start podcasting” without getting overwhelmed by equipment decisions.
Regardless of which interface you choose, remember that your microphone technique, room acoustics, and content quality matter more than equipment specifications. I’ve heard outstanding podcasts recorded on budget interfaces and terrible shows produced with premium gear. These interfaces remove technical barriers and provide professional sound quality, but they’re tools that serve your creative vision rather than substitutes for it.
Frequently Asked Questions
Do I really need an XLR interface, or can I use a USB microphone for podcasting?
XLR interfaces paired with quality dynamic microphones provide significantly better sound quality, room noise rejection, and upgrade flexibility compared to USB microphones. After testing both extensively, I recommend XLR setups for anyone serious about podcasting beyond casual experimentation. The interfaces reviewed here offer professional audio quality that USB microphones simply can’t match due to their built-in analog-to-digital converters and preamps. Additionally, XLR setups let you upgrade microphones independently without replacing the entire recording chain, and they handle challenging acoustic environments far more gracefully. That said, quality USB microphones work perfectly fine for beginning podcasters still determining if they’ll commit to regular production—just recognize you’ll likely upgrade to an XLR system once you become more invested in audio quality.
How many inputs do I actually need for podcast recording?
Most podcasters should start with two inputs—one for yourself and one for an occasional co-host or guest. Single-input interfaces like the Audient EVO 4 work beautifully for solo shows but become limiting quickly if you want interview flexibility. Four-input interfaces like the RODECaster Pro II provide room for panel discussions but represent overkill (and unnecessary expense) for podcasters who primarily record alone. Consider your content format realistically: if you’re planning a conversational show with a regular co-host, two inputs are essential; if you’re conducting solo commentary or interviews exclusively with remote guests, a single input suffices. I’ve found that most podcasters eventually want the flexibility of at least two inputs, even if they don’t use the second one regularly, since having the option eliminates the frustration when recording opportunities arise unexpectedly.
What’s the difference between interface preamps, and why does it matter?
Preamps amplify your microphone’s signal to line level, and quality variations dramatically affect your final sound. Better preamps provide cleaner amplification with less noise, more headroom (the distance between your average signal and clipping), and often more pleasing tonal characteristics. In practical terms, I’ve noticed that cheap preamps require you to crank the gain to achieve adequate recording levels, which introduces audible hiss and noise. Quality preamps like those in the Universal Audio Volt or Audient EVO provide clean gain at any setting, letting dynamic microphones like the Shure SM7B shine without requiring additional preamp boosters. The difference becomes especially noticeable during quiet moments in conversations—better preamps maintain a silent noise floor, while budget options introduce the persistent hiss that screams “amateur production” to experienced listeners.
Can I connect these interfaces to iPads or smartphones for portable recording?
Most modern interfaces support iOS connectivity with appropriate adapters, though power requirements vary significantly. Bus-powered interfaces like the Audient EVO 4 work reliably with iPads (especially iPad Pros) when using Apple’s USB Camera Adapter with external power. The Focusrite Vocaster series and Universal Audio Volt line also support iOS recording, though I’ve found that tablet recording introduces workflow complications that often aren’t worth the portability benefit. Smartphone recording through these interfaces remains technically challenging due to power demands and app limitations.
