Thank you for choosing Polsen.

The Polsen MP-25 Megaphone is a powerful 
and durable solution for voice amplification and 
is ideal for high-noise areas and large open 
spaces. With a maximum output of 25 watts, 
the MP-25 is audible over 1,500 yards away.

The MP-25 features an attached hand-held 
microphone with a coiled cable allowing 
operators to face a different direction than the 
crowds they are addressing. The microphone 
can also be mounted on the mic holder enabling 
easy, one-handed operation.

The MP-25 also features a built-in MP3 decoder 
that plays files stored on SD cards or flash 
drives. Since the microphone and MP3 player 
have independent volume controls, users 
have the option of speaking over music or 
prerecorded audio. For more playback options, 
mobile devices such as MP3 players or smart 
phones can also be connected to the MP-25 
through the 3.5 mm auxiliary (Aux) input jack.

Tough ABS construction of the outer shell 
protects the megaphone from impact and 
the demands of outdoor use. The included 
adjustable shoulder strap provides extra support 
during periods of extended use.
