Main Features
**This is the first kind of microphone created with 2.4G Digital Wireless
Technology, avoiding interferences issues commonly stipulated in wireless
microphone before successfully that you can enjoy high-quality sounds now.**
z DWM1 is equipped with thick and solid bass and clear pitch that highly sensitive
sound head enables presentation of genuine human voice which is applicable to
multiple purposes such as singing, giving speech, conference and teaching.
z First innovative 2.4G Digital Wireless Technology in Industry is used for
no-harassment in management of channels with audio quality in perfection
rendered!
z 2.4G Digital Wireless Technology is featured with its high-speed transmission
and 60m linear reception.
z None of interference issues incurred with multiplayer in one room because of its
capability of 3 sets wireless microphone system extended.
z Volume Adjuster is uniquely attached that + - buttons on the microphone enables
to adjust volume remotely with ease; the thoughtful installation of switch at
thumb grip under ergonomic design enables switch on/off only via pressing
buttons.
z The exterior streamlined design, in line with visible pearl white paint and further
thermal UV treatment, is free of paint falling everlastingly which highlights its
high quality.
z The dustproof net, made of high-stiffness of steel, presents higher level of
protective effects from extremely precise electroplating treatment and coating on
the surface; the closely integrated design in the sound head and net head of
microphone is excellent in drop and shock resistance which significantly reduces
extra sound generated from shakes.
z 2.4G Technology is featured on its extremes of energy saving; wireless
microphone powered from common kind of alkaline battery(1.5V AAA x2) is
endurable more than 35 hours successively.
z Design of Energy Saving：10 minutes putting aside without any sound input will
power off the microphone; function of low-pressure alert will turn the switch
light to red while the battery is running out.
z Function of LED expressions on volume and digital number on receiver makes it
be in easier and faster operation.
z Mini Antenna at unique design reduces more chances in damages of bending; it
can be rotated at 180 degree and folded up at 90 degree which makes storage be
simpler.
z The ultra-thin design of mini receiver at 200g enables you to hand carry in
convenience or include it into decoration at home simply.
