User Manual
Setting up
The MDU-40 is a miniature desktop microphone with back-electret capsule,
designed to provide a more direct and higher quality input for voice recording
or streaming via a laptop or desktop computer.
The MDU-40 has a cylindrical metal body and dome grille and is supplied with a
custom desktop stand that fixes to the bottom of the microphone body. The
MDU-40 has a USB type-C socket at the rear and is supplied with a type-C to
type-A lead for connection to a USB port on a Mac or Windows computer. This
provides power to the microphone and delivers the sound picked up by the
capsule as a digital audio signal to the computer.
The computer will recognise the MDU-40 as a “USB PnP Sound Device” in the
sound or audio settings.
Operation
Selecting the MDU-40 (“USB PnP Sound Device”) as the input device within the
recording or streaming software will set the microphone as the input source.
An illuminated button on the top of the body will mute the microphone as
required.
The MDU-40 can be disconnected and re-connected to USB as a hot-swappable
device. Disconnect from USB after use to preserve the computer battery or
power supply.
