4ms Listen Four is a 4 channel stereo mixer that can output at modular or line level and has a dedicated headphone out, allowing use as mixer, output module, or mixer with headphone feed for monitoring and confidence! Two channels have mono inputs with pan control and two channels have stereo inputs. Also has level controls for the master output and the headphone output - super handy module!

Note: This is a used item, and while it is guaranteed to be fully functional it is almost sure to also contain "rack rash" on the mounting holes and have some minor scratches on the panel from use. It will include a ribbon cable, m3 screws, and a box, but not the original box.
