MX400 4-Channel Mini Line Mixer with Independent Level Control
The MX400 is a compact 4-channel line mixer for small studios, desks and live setups that have run out of inputs. Four line sources go in, each with its own level knob, and one clean mixed output comes out on a 6.35 mm TS jack. The metal chassis is small enough to sit beside a laptop, and the ultra-low-noise circuit keeps keyboards, synths, drum machines and players summed without adding hiss.
Key Features
- Ultra Low Noise — Clean signal with minimal distortion, so the mix stays transparent even with several sources running.
- Independent Level Control — A dedicated knob on every channel (0-10) lets you balance four sources separately instead of juggling one master.
- Compact Metal Design — A small, solid metal chassis that sits on a desk or pedalboard without eating your workspace.
- Easy Audio Expansion — Combines multiple audio sources into one output - add inputs to a rig that has run out.
- Plug & Mix in Seconds — Connect your sources, set each level, then send the mixed output to your speaker, amplifier or monitoring chain.
- Made for Home Studios — Suits keyboards, synths, drum machines, microphones and MP3 players in a compact home setup.
