If you need more inputs, simply plug in the optional EXH-6 Dual XLR/TRS Combo capsule. It allows you to connect two additional discrete signals from external microphones, instruments, mixers, or portable music players, turning the H5 into a four-input recorder and making the H6 the smallest six-input recorder on the planet! The EXH-5 dual XLR/TRS input capsule is compatible with the Zoom H5 and H6 Handy Recorders, the U-44 Handy Audio Interface, the F4 MultiTrack Field Recorder, and the ECM-3 extension cable for Zoom microphone capsules.
