Xer Dualis is a compact four-channel stereo mixer. Use the individual left and right inputs for your stereo signals, or just the left input for a mono signal: it normals to the right one. Each channel has a mute and an individual level control so you can fine-tune your mix to your taste. XD’s stereo output pair features a simple meter and a clip indicator to help keep your mix clean. Grab Xer Dualis whether you need a submixer for a large system or an easy way to mix all the elements of a portable case together.
