Motivation
This is the little brother to my 9 in 2 Mixer. For those which need more channels. I have reduced the channel count to seven but made the mixer stackable and added a main output volume control. It is still usable as simple submix with pre- and post fader out, pan adjustment and stereo out. Nothing special and overlay complicated. Only for module mixing and mixing in some effects to this or that channel. A seven channel mixer with faders for the volume, panpots, pre- and post fader out per channel and stereo mix out with volume control. The chain in- and outputs are pre- and post fader as well.
