The EXH-6 from Zoom adds two additional XLR/TRS combo inputs to the Zoom H5 and H6 handheld recorders, or to the F4 field recorder. This makes the H5 capable of recording up to four external mic/line signals simultaneously, and the H6 or F4 up to six. Capable of handling either mic- or line-level signals, each input is equipped with its own preamp and -20 dB pad. Please note, this module does not provide phantom power.
