24-Bit/192kHz USB Audio Interface

The RCA usb-box-2025-b is a 24-bit/192kHz USB audio interface designed for recording, streaming and podcasting. It provides two XLR/Line combo inputs with independent gain controls and 48V phantom power for condenser microphones. The unit is USB-powered and works with Windows, macOS and compatible smartphones without additional drivers.

Dual Inputs and Direct Monitoring

Dual combo inputs allow two sources such as a microphone and an instrument to be recorded simultaneously. A direct monitor switch enables zero-latency headphone monitoring while recording. Stereo line outputs connect studio monitors, and both USB-C and USB-A cables are included for immediate connection to a computer or mobile device.

For Solo and Dual-Source Creators

This interface suits musicians, podcasters and streamers who need two simultaneous inputs with phantom power and portable USB operation. It does not meet the needs of users who require more than two preamps, built-in DSP effects or standalone operation without a host device.
