SonixForce SMX4 4-Channel Mixer

The SonixForce SMX4 is a four-channel audio mixer built for podcasters, streamers and small bands who need multiple microphone and line sources in one compact unit. It provides two studio-grade combo XLR/TRS inputs, two dedicated stereo line inputs and 99 onboard DSP effects for shaping vocals or instruments. A 30-degree angled aluminium chassis keeps controls visible during long sessions.

Sustained operation with 48V phantom power

The mixer runs from a universal 110-240V corded supply so voltage stays stable during extended recordings or live streams. High-quality audio chips are specified for zero distortion and latency even when all four channels and the DSP engine are active. The aluminium shell aids heat dissipation while the ergonomic angle reduces operator fatigue over multi-hour use.

Check your microphones and monitoring needs

Verify that any condenser microphones you plan to use require 48V phantom power, which is engaged by a single switch on the unit. Ensure you have XLR or TRS cables for the two combo jacks and suitable RCA or ¼-inch leads for the stereo line inputs. The USB port serves both as a computer audio interface and for direct flash-drive recording, so confirm which workflow matches your setup.

Questions about this item

Does the SMX4 run hot or make fan noise during long sessions?

The mixer uses a universal 110-240V power board with no fan mentioned, so it stays silent and cool during extended use.

What cables and sources do I need before the SMX4 will pass audio?

Connect microphones to the two XLR/TRS combo jacks, line sources to the stereo inputs, and power it from a 110V outlet; a USB flash drive or computer completes the chain.

Will my older dynamic microphones work with the SMX4 without extra gain?

Yes, the two combo XLR/TRS inputs accept dynamic mics directly, while the 48V phantom power is only needed for condenser models.
