Description
Product Overview
The R4 PRO 4‑channel audio mixer is engineered for creators who demand flexibility and reliability in a single, portable unit. Measuring just 1.77 x 7.08 x 9.25 inches, the mixer packs a powerful 48 V phantom power supply, a 1/4‑inch audio hardware interface, Bluetooth 5 connectivity, and a USB 2.0 port for direct digital recording. Two built‑in UHF wireless microphones automatically pair when the MIC ON button is engaged, offering ten groups of frequency selection to avoid interference. Each channel includes a three‑band EQ, a PAD button for -20 dB attenuation, and a high‑precision LED peak level indicator, ensuring you can fine‑tune vocals and instruments with confidence. The mixer also supports XLR inputs with +48 V phantom power, making it compatible with professional condenser microphones for studio‑grade recordings.
Beyond the core mixing capabilities, the R4 PRO features a versatile routing system that lets you send the mixed signal to headphones, powered speakers, or a PA system via the 1/4‑inch outputs. The Bluetooth module enables wireless playback from smartphones, tablets, or laptops, while the USB interface acts as an audio bridge for DAW software, allowing multi‑track recording directly to your computer. With a robust metal chassis and a sleek matte finish, the mixer is built to withstand the rigors of touring, live events, and frequent transport, yet remains lightweight enough for home studio setups.

Usage
Designed for a wide range of environments, the R4 PRO excels in home karaoke parties, small club DJ sets, and professional streaming studios. In a karaoke setting, the dual wireless microphones free performers from tangled cords, while the built‑in echo and reverb effects add depth to vocal tracks. For DJs, the four channels allow seamless blending of tracks, live instrument inputs, and microphone cues, with the Bluetooth receiver providing instant access to playlists without interrupting the mix. The USB audio interface makes it simple to capture high‑resolution recordings for podcasts, voice‑over work, or music production, eliminating the need for additional external sound cards.
Because the mixer runs on a corded 48 V power source, it delivers consistent performance without battery drain, making it ideal for extended sessions at events or studio marathons. The intuitive layout—featuring clearly labeled knobs, switches, and LED indicators—means even beginners can start mixing within minutes, while seasoned engineers appreciate the precise control over gain staging and frequency shaping. Whether you are broadcasting a live stream, recording a cover song, or hosting a community karaoke night, the R4 PRO adapts to your workflow and enhances the overall audio experience.
