DNA EF-MIX 4 USB MP3 Bluetooth analoge audiomixer

In a small home studio, a podcaster connects two condenser microphones to the DNA EF-MIX 4, engages phantom power, and records directly to a laptop via USB while monitoring through headphones. The mixer’s compact metal chassis sits neatly on the desk, and a smartphone pairs over Bluetooth to play intro music for the live stream.
