THANK YOU FOR CHOOSING POLSEN
The Polsen MVS-5 Stereo Shotgun Microphone
is a rugged, compact, and lightweight mic
designed for recording audio directly to a DSLR
camera or portable recorder. It delivers pristine
and quiet professional-quality sound and is a
vast improvement over a DSLR camera’s built-in
microphone.
This dependable microphone features two
condenser cardioid capsules arranged in an
X-Y pattern for capturing audio with realistic
stereo imaging. The microphone is powered
by a single 3 V coin battery for 36 hours of run
time with most cameras and recorders that
have a 1/8-inch audio input connector. The
MVS-5 attaches to a camera’s shoe mount or
tripod, and its all-metal construction makes it
a great addition to a camera rig for a variety
of eld and run-and-gun productions like
documentaries, music videos, sporting events,
and nature videos.

RECORDING
1. Plug the audio output cable into the 1/8-inch
audio input jack on the recording device or
camera.
2. To turn on the microphone, slide the
power switch to either the at or
high-pass position.
Note:Smartphones that have a Lightning or
USB Type-C™ connector will require an adapter
(sold separately).
USING THE HIGH-PASS FILTER
The high-pass lter attenuates noise below
80 Hz. This helps prevent the microphone from
recording low-frequency noises like the rumble
of an air conditioner, blower, or fan.
To turn on the high-pass lter, slide the switch
to the high-pass position . Set the switch
to the at position if the high-pass lter
isn’t needed.
8
USING THE THREE-LEVEL
GAIN SWITCH
The three-level gain switch provides normal
0 dB gain, a +10 dB boost, or -10 dB pad.
•0 dB:The microphone’s normal gain setting.
This is the optimal setting for recording
normal speech or dialog.
•+10 dB:Boost the microphone’s gain to
record low-level or distant sounds in a quiet
environment.
•-10 dB:Attenuate the level of the incoming
signal to record in high-decibel environments,
like a rock concert or sporting event.
