usb 24 bit audio interface

Most of the interfaces support 24-bit resolution. Common sample rates reported are 96 kHz and 192 kHz (e.g., 24-bit/96 kHz and 24-bit/192 kHz).

They range from compact 2-in/2-out desktop units up to expandable multi-channel systems. Examples include simple 2-in/2-out designs, standalone units with multiple combo inputs, and expandable setups supporting up to 24 inputs.

Yes — many of the interfaces include switchable +48V phantom power to support condenser microphones.

Besides USB-C/A, models may offer S/PDIF (coaxial), TOSLINK optical inputs, analog RCA outputs, Bluetooth, and standard 5‑pin MIDI I/O on some units.

Power methods vary: some are bus-powered via USB, some offer battery options (one mobile model uses 2×AA), and others support external DC power or USB Power Delivery.

At least one system is explicitly modular and expandable: it uses a hub with personal units, can be expanded to multiple stations, and provides per‑user monitoring controls and personal reverb/level settings for multi‑musician tracking or rehearsing.
