If you need more inputs, simply plug in the 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.
The EXH-6 dual XLR/TRS input capsule is compatible with the Zoom H5 and H6 Handy Recorders, the U-44 Handy Audio Interface, the F1 Field Recorder, and the F4 MultiTrack Field Recorder, and the ECM-3 extension cable for Zoom microphone capsules. Correct at time of writing – other units may have since been released that are also compatible.
NB: This capsule cannot be used in conjunction with the XY capsule or directional mic that come with the H6 as it uses the same port.
