## What reviewers say

**Volt 2 USB Audio Interface** — Only one whitelisted tester, SoundGuys, covers the Volt 2, and only as a pick inside a buying guide rather than a dedicated lab review, so there are no measured numbers. It endorses the Volt 2 as a capable sub-$200 Focusrite Scarlett alternative with 610-style preamps. No cross-source corroboration exists on the whitelist. (1 sourced review.)

**Studio 24c** — Only one whitelisted hands-on review of this exact model survived verification (MusicRadar, Sept 2023). It calls the Studio 24c a hard-to-beat sub-$100/£100 2-in/2-out interface with clean, high-headroom PreSonus mic and instrument preamps, full MIDI I/O and streamer-friendly Loopback routing, docking it only for closely-spaced controls and a rear-mounted headphone jack. The review is qualitative with no published lab measurements (latency, dynamic range, THD). (1 sourced review.)
