The Sound Professionals web site now shows three accessories for the Zoom H4.
These are designed to work with mics that need 9v plug-in power, and
that have 3.5mm plugs on the cable from the mic, preamp or battery box.
All three of these accessories use a module that plugs in to the dual XLR ports
on the bottom of the H4.
The most expensive gadget has
-- a pair of Omnidirectional mics mounted on opposite sides of the plug-in module
-- a 24V phantom to 9V plug-in power converter, and
-- a 3.5mm TRS input jack for one or two external mics
SP-ZOOM-OMNI-MIC, $89
The next module leaves out the Omni mic capsules. It has
-- Phantom power to plug-in power converter, and
-- a 3.5mm TRS input jack for one or two external mics
SP-ZOOM-PHANTOM, $69
The cheapest has only the interface jack for mics with 3.5mm plug.
SP-ZOOM-INTERFACE, $39
In all three cases, the single 3.5mm TRS jack permits connection of two mics
via Y cable.
