MANUAL
OMNIDIRECTIONAL
USB GOOSENECK
MICROPHONE
GM3-USB
THANK YOU FOR CHOOSING
POLSEN.
The Polsen GM3-USB microphone is an ideal tabletop
mic for gaming and video conferences. Its compact
form factor takes up a small footprint on your
desktop, and the flexible gooseneck precisely aims
the mic at the sound source. You can speak naturally
during gaming sessions, video conferences, and
Zoom chats without bending toward the microphone.
The GM3-USB plugs directly into an available USB
port on your computer and is instantly ready for use
on Windows and Mac computers. The microphone
runs off the power from the USB port so batteries
and charging cables aren’t needed. The omnidirec-
tional polar pattern picks up sound from 360° around
the microphone so it will accurately capture a group
of presenters without moving or re-aiming the
microphone.
PRECAUTIONS
• Please read and follow these instructions, and keep
this manual in a safe place.
• Do not turn the microphone towards loudspeakers.
This can result in acoustic feedback, which can
damage both the loudspeakers and microphone.
• Clean this product with only a soft, dry cloth.
• Make sure that this product is intact and that there
are no missing parts.
• All images are for illustrative purposes only.
