The 4ms Listen Up Kit is a DIY kit that includes all the parts necessary to build a Listen Up. The DIY Kit is very easy to build and suitable for first-time kit builders, and once built, this small passive expander for the Listen modules provides stereo 1/4" jack inputs and outputs. There are four 1/4" jacks arranged in Left/Right pairs. The Left In and Left Out jacks are TRS stereo if corresponding Right jack is not unpatched. The Listen Up requires the Listen IO, Listen Four, or WAV Recorder Module and connects to the back of any of those with the included 3-pin cables.
