The mighty Zoom H8 is already a powerful field recorder packed with masses of options, one of which is the detachable and swappable head. Remove it, and you can replace it with this: the Zoom EXH-8 XLR expansion module, and add an extra four XLR inputs, bringing the total up to ten. This add-on is ideal for supporting large conference meetings, ensuring that everyone has a microphone, or for other multi-source setups.
