The SQN-4SB mixer is an upgraded revision of the SQN-2S which created new size and weight benchmarks for the miniature ENG mixer. This elegant design puts the essence of the well known SQN-4S Series IVe 4:2 mixer into a case identical in size to the earlier SQN-3M mono mixer. The new version has new control knobs for the two secondary channels which both improve handling and mark them visually as channel faders. It also features the addition of bass cuts on Channels 3 and 4s.
The essential information for connecting to and operating the mixer is permanently printed on the baseplate.
