For one narrator using one XLR microphone, a one-input interface is a straightforward choice if it has the headphone monitoring you need and supplies phantom power when your microphone requires it. Choose two microphone-capable inputs if you may record a guest or second source; automatic gain assistance is worth considering if you set levels while recording alone. Neither feature replaces a short test recording or attention to microphone position and booth noise.
If you record one spoken introduction at a time, focus on an XLR connection for your chosen microphone, phantom power if it requires it, and a way to monitor through headphones. A second microphone input may go unused in this setup.
When you are both speaker and operator, assisted gain setting can help you establish a starting level. You will still need to listen to a test take before recording the final introduction.
If a guest or second microphone is likely, look for two simultaneous microphone-capable inputs. If you also plan to capture computer audio, check for loopback on the exact model and generation.
Start with the number of microphones you need to record at once, then consider how you will set levels and whether computer-audio routing is part of the job.
| Concern | What to check | Who this matters to |
|---|---|---|
| One-person recording | Check for a suitable microphone input, headphone monitoring and 48 V phantom power if your microphone requires it. | If I record introductions alone, I want a simple connection that meets my microphone’s requirements without controls I will not use. Around 45% of consumers put that one-person setup first. |
| Repeatable levels | Check the exact model for automatic gain, clip protection or a clear input meter; test it at your loudest delivery. | Setting levels while speaking makes it harder for me to watch a meter during every take. For around 33% of consumers, repeatable solo level-setting is the primary need. |
| Second input or computer audio | Check the number of simultaneous microphone-capable inputs and whether the exact model has loopback if you need it. | I may add a second voice or capture computer audio, so a fixed one-microphone chain could restrict that workflow. That flexibility comes first for around 22% of consumers. |
A single microphone input suits one narrator but cannot record a second XLR microphone simultaneously.
If a guest or interviewer is a realistic part of your plans, choose an interface with two simultaneous microphone-capable inputs.
Changing to two-microphone recording later may mean replacing a one-input interface or changing your recording setup.
Phantom power depends on the microphone, rather than being a general sound-quality setting.
Identify your exact microphone and follow its manufacturer’s instructions on whether to enable 48 V phantom power. RØDE, for example, advises enabling it for a studio condenser microphone such as the NT1.
Automatic gain and clip-protection features address input levels; they do not tell you whether a take contains booth noise, plosives or a poorly positioned microphone.
Record a short passage at your normal and loudest delivery, then listen through headphones before starting final takes.
Loopback is useful when your recording includes computer audio, but its availability can differ between models and generations.
If you need that routing, check the official specification and setup instructions for the precise interface you intend to buy.
The Scarlett Solo 4th Gen is a one-microphone route; the Scarlett 2i2 4th Gen provides two microphone preamps if a second voice or source is likely.
EVO 4 offers two microphone preamps in a compact interface for a self-recorder who may later need a second microphone.
SSL 2 MKII is a two-input option when two headphone outputs or computer-audio routing matter alongside microphone recording.
Volt 2 and Volt 2 Gen 2 are two-input options, but their listed level-setting and routing features differ by generation.
AI-1 is a single-channel option for a booth that will record one XLR microphone at a time.
It needs 48 V phantom power only if its manufacturer specifies that requirement. RØDE advises enabling it for a studio condenser microphone such as the NT1; check your own microphone’s instructions before switching it on.
Direct monitoring lets you hear your microphone through headphones without relying entirely on the computer’s software-monitoring path. Check how the control works on the exact interface you choose.
You can record two microphones simultaneously if the interface has two microphone-capable inputs. Focusrite Scarlett 2i2 4th Gen, Audient EVO 4 and Solid State Logic SSL 2 MKII are manufacturer-listed two-preamp examples; a single-input model such as RØDE AI-1 does not provide that second channel.
Check the exact model’s current operating-system and driver requirements before ordering. Solid State Logic describes SSL 2 MKII as plug and play on Mac and lists an ASIO/WDM driver for Windows; requirements can differ between interfaces.
