The do-it-yourself kit 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. Basic hand tools are required.
The Listen Up is a small passive expander for the Listen modules that provides stereo 1/4" (6.35mm) jack inputs and outputs. There are four 1/4" jacks arrange in Left/Right pairs.
The Left jack of each pair can be used as a TRS stereo jack if the Right jack is unpatched. The Listen Up connects to one or two Listen modules with the included 3-pin cables.
