The MDR624 is a six-channel mixer with two low noise microphone preamps. 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 3-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. Additionally, LED indicators for power, phantom, peak and main output level make it easy to keep your levels set correctly and minimize distortion. With its professional features and advanced circuit design, the MDR624 gives you the tools necessary to ensure high-quality sound and reliable performance from one venue or session to the next.
