      Amplifier, able to provide higher efficiency in power use for the system as well 
      as offer outstanding audio output. 
Powered by Lithium battery
      The system incorporates 14.8V lithium battery*1, able to provide the system   
      with higher output power and reduce the unit weight by about 30%, enabling 
      the use by carrying for long hours. Continuous music playback can last 7 hours; 
      continuous voice speech can last 10 hours*2.
Splash-proof design,
enables use in severe environment*3.
UPS design
:when power supply in DC is inputted/removed, the unit switches                  
to DC/Battery supply mode automatically without affecting the system operation.
Energy conserving device:
when the sound source devices are not in use*4, the 
system automatically switches off the amplifying circuit, which saves 60% of the 
energy, effectively lengthening the standby time of the system. 
Wireless microphone system:
incorporates a built-in wireless microphone system 
with UHF band, which works with Mh-35 handheld wireless microphones 
(powered by one single AA cell) to provide 100M non-interfered transmission 
and 16 channels to choose from.*5, *6

      emergency evacuation.
Built-in audio:
supports music playback via USB/SD, and 20 programmable 
channels of FM radio stations. 
※Notes:
1. The system operates on 14.8V power supplied by lithium battery which is 16.8V fully charged. When  
   the battery is below 12V, the system switches off forcibly to avoid over-discharge.
2. The above-stated time of device use are for reference only. They vary according to the volume 
    adjustment.
3. The description refers to spills which may happen in everyday life.
4. Sound source devices refer to “wireless microphone system”, “built-in audio” and “input from 
   microphone with cord”.
5. The low power radio device has passed the type approval; any firm, vendor or user may not tamper  
   with by changing its frequency, amplifying its power or altering its originally designed features and 
   functions without permission.
6. The use of low power radio device may not affect aviation safety or interfere with legal 
    telecommunication. The use should be stopped immediately when any interference is found; no 
    use may be resumed until interference is eliminated by improvement. The above-mentioned legal 
    telecommunication refers to radio communication operated under telecom regulations. The low power 
    radio device tolerates interference from legal telecommunication or radioactive devices for industrial, 
    scientific and medical use.
