DNA PROFESSIONAL DNA MIX-EFF 4 Analog Audio Mixer 4 Channels with USB

The DNA MIX-EFF 4 stands apart from typical compact mixers by combining a true analog signal path with a built-in 16-preset effects engine and a USB audio interface—all in a rugged metal chassis. While many small mixers offer only basic mixing, this unit gives you four channels, two with studio-grade XLR/TRS combo inputs and switchable +48V phantom power, plus stereo line inputs on both 1/4" TRS and RCA. Whether you're running a live show, recording a podcast, or adding depth to karaoke, the MIX-EFF 4 delivers clean, low-noise performance with a frequency response from 20 Hz to 20 kHz and THD below 0.01%.

Highlights

• 4-channel analog mixer with 2 mic/line combo inputs and 2 stereo line inputs
• Built-in 16-program FX processor: reverb, delay, chorus, flanger
• USB 2-in/2-out audio interface, 16-bit/48 kHz for direct computer recording
• +48V phantom power for condenser microphones
• 2-band EQ on each channel for quick tonal shaping
• Balanced main outputs and dedicated headphone output
• Durable metal chassis with external DC power supply

In daily use

The MIX-EFF 4 is built for fast, intuitive operation. Each channel gives you gain, 2-band EQ, pan, and level controls, while the master section includes volume, FX send, and FX level. Connect dynamic or condenser mics to the combo jacks, plug a keyboard or media player into the stereo line inputs, and send the mix to powered speakers or an amplifier via the balanced TRS outputs. The USB port lets you record directly to a computer or stream audio back for playback. The onboard effects are easy to dial in—just select one of 16 presets and adjust the send per channel. With its compact footprint and robust build, it fits neatly on a desk or in a rack.
