Vonyx STM-3020B - 6-Channel Mixer with USB/MP3, Crossfader and Talkover
The Vonyx STM-3020B is the ultimate entry point into the world of professional audio and mixing for beginner DJs and discerning enthusiasts alike. Designed as a compact yet powerful all-in-one solution, this mixer stands out for its incredible versatility of connections and intuitive interface, allowing for easy management of multiple audio sources. Its sleek black finish and robust construction make it the perfect control center for karaoke setups, podcasters, video soundtrack mixing, or small home DJ sessions .
Despite its compact size, the STM-3020B is a connectivity powerhouse. Marketed as a "6-channel" mixer, it boasts a wide array of switchable inputs: two phono inputs , three line inputs for CD players, computers, or tuners, and a dedicated MP3 channel . This flexibility allows you to connect virtually any modern or classic audio device without constantly unplugging cables. Furthermore, its integrated MP3 player with USB port eliminates the need for external background music sources, offering complete autonomy with direct playback on its digital display.
The technical functionality is equally impressive. The mixer incorporates essential tools for learning and live performance, such as the Talkover function, which automatically lowers the music volume when you speak into the microphone—ideal for entertainers and presenters. The smooth crossfader allows for seamless transitions between the main channels, while the per-channel cue function ensures that each mix is perfectly synchronized before reaching the main speakers. With adjustable EQ for the MP3 player and independent microphone volume control, you'll have complete control over your sound.
