For one vocalist at a shared desk, start with an interface that has an XLR microphone input, controllable gain, a headphone output and a way to hear the input while recording. One microphone preamp is enough if you record one mic at a time; consider two if a second microphone or stereo source is a realistic next step. Check the unit's footprint, your microphone's power requirement and the monitoring controls before treating extra connections as a benefit.
If your microphone, computer and work equipment share a desk, compare the interface's dimensions and allow room for connected cables. Check that you can reach its controls and monitor through headphones without relying solely on software playback.
If setting input level is new to you, look for controls or gain assistance you can understand and test them with your loudest intended phrase. Check your microphone's instructions before enabling phantom power.
If you may add a second microphone, an instrument, computer-audio capture or MIDI, choose connections for the sources you expect to use together. An additional input is useful only if its connector and preamp suit that source.
For solo vocals at a shared desk, settle the microphone connection and monitoring first, then decide whether your available space and likely future sources justify more inputs.
| Concern | What to check | Who this matters to |
|---|---|---|
| Vocal input and gain | Confirm an XLR microphone input, controllable gain and whether your particular microphone requires 48 V phantom power. | If I record passages that vary in loudness, I need a suitable mic connection and room to set the level without clipping. Around 33% of consumers put reliable vocal capture first. |
| Desk footprint | Measure the available space, including clearance for cables, and check the position of the mic and USB sockets. | When the desk must still serve other tasks, I need the interface and its connected cables to fit without getting in the way. Around 27% of consumers make workable desk space their primary concern. |
| Headphone monitoring | Look for a headphone output and check how direct monitoring or monitor mix and input-level indication work. | I want to hear my voice through headphones and set up quickly without using desk speakers. For around 27% of consumers, that low-disruption workflow comes first. |
| Future connections | Count sources you would record simultaneously; check the second input's type and whether your intended software can use any loopback channels you need. | If a second performer, computer audio or MIDI is a likely next step, I want the connections that step actually requires. Around 13% of consumers prioritise that flexibility. |
Focusrite specifies one XLR microphone input and a separate line/instrument input on Scarlett Solo 4th Gen. Audient EVO 4 and the original Universal Audio Volt 2 each have two microphone preamps, according to their manufacturers.
Count the microphones and other sources you need at the same time, then check the exact connectors and preamp allocation for the model you choose.
Some microphones require phantom power, but Audient cautions that it can damage certain microphones in rare cases.
Check your microphone's instructions before connecting it or enabling 48 V; do not assume every vocal microphone needs it.
At a shared desk, the ability to set a usable input level and hear your voice through headphones affects the recording routine. Gain assistance still needs a test at your loudest expected vocal level.
Check the headphone and monitoring controls, then test input level with a representative passage before recording a full take.
Focusrite warns that incorrect loopback routing can create feedback when capturing computer audio alongside a microphone.
If you need loopback, check the model-specific routing instructions and whether your recording or streaming software exposes the required channels.
Focusrite's Scarlett Solo 4th Gen is a route for recording one XLR vocal microphone, with a separate line/instrument input, headphone output and direct monitoring.
Audient's EVO 4 combines two microphone preamps, a headphone output, monitor mixing and loopback in a unit it specifies as 140 × 67 × 67 mm.
The original Universal Audio Volt 2 is a bus-powered USB interface with two microphone preamps, direct monitoring and MIDI connections.
You need 48 V only if your particular microphone requires it. Audient advises checking the microphone documentation before enabling phantom power, because some microphones can be damaged by it in rare cases.
One microphone input is enough if you record only one mic at a time. Focusrite's Scarlett Solo 4th Gen has one microphone preamp; Audient EVO 4 and the original Universal Audio Volt 2 have two if simultaneous recording of another microphone is a realistic requirement.
Yes, if the interface provides suitable direct-monitor or monitor-mix controls and a headphone output. Focusrite documents a direct-monitor control on Scarlett Solo, while Audient describes using EVO's Monitor Mix to hear its microphone input; check how the control works on the model you select.
The applicable marking routes differ between Great Britain and Northern Ireland. For electrical equipment, the GOV.UK product-marking table dated 31 March 2026 lists UKCA or CE for Great Britain, and CE or UKNI together with CE for Northern Ireland. Check the product documentation for the market where it is supplied rather than assuming one marking arrangement applies throughout the UK.
