Teenage Engineering ZM4 I/O Expansion Module for OP-Z

Line Module is designed to bring external audio signals in and out of your OP–Z. It adds a stereo line input and an additional stereo line output to the unit, as well as input and output for midi, trig and PO sync. Use line in to add external audio signals to your mix and use line out as a second stereo output available within OP–Z.

Route individual tracks to the module output instead of to the main mix to separate and process the individual tracks, or make effect loops with your favourite effect pedals. Easily switch between mono and stereo signals depending on your needs. Now you can turn your humble OP–Z into a live performance dream machine.
