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.
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.
