Congratulations on your purchase of the Samson MDR624 mixer! The MDR624 is a six channel mixer, with two
low noise microphone pre-amps. In addition to the two mono Mic/line inputs, there are two channels with left and
right inputs to handle stereo signals. For added flexibility, you can change the tone quality of your microphones or
other line inputs by using the three-band channel equalizers. Connecting external effects like a reverb or digital
delay to the MDR624 is easy thanks to the Aux send on each channel along with the stereo Aux Return in the
master section. LED indicators for Power, Phantom, Peak and Main Output Level make it easy to keep your lev-
els set correctly and minimize distortion. Clean, clear sound reproduction, packaged in a rugged enclosure,
ensure reliable high quality sound from performance to performance. Optimized for recording, live sound rein-
forcement and commercial installations, the MDR624 is an ideal mixer solution offering big sound in a compact
package.
In these pages, you’ll find a detailed description of the features of the MDR624 mixer, as well as a description of
its front and rear panels, step-by-step instructions for its setup and use, and full specifications. You’ll also find a
