DRM Control Dashboard™

When setup time is limited, changes need to happen on the fly, or you just want to get your system going without extra hassle, the last thing you need is the controls on your loudspeakers being difficult.

The DRM Control Dashboard™ starts with a big, bright, full-color display that is easy to read and offers unmatched visual feedback on levels, adjustments, and more. The default window keeps you informed on every critical setting at a glance. Big green level meters let you know clearly when you have signal and if it is clipping.

But how do I control it? One single knob, that's it. Spin to select what you want, push in, set it how you like it, done.

DRM18S Cardioid

Keep The Bass Out in Front

Subwoofers are naturally omni-directional. This means that the sound they project goes in all directions. This can sometimes cause excess bass buildup, feedback issues, and more on stage. That's where cardioid comes in. Cardioid subwoofer setups are incredibly helpful when you want all that rumble off of the stage and out to your audience. It accomplishes this by utilizing multiple subwoofers, with one facing in the opposite direction. This works because the rear-facing sub cancels out quite a bit of the bass that would otherwise be shaking the stage and in turn sends it all you your audience. The DRM18S has settings located in the DRM Control Dashboard that make it easy. You can arrange them side by side or in a stack.
