Precautions for use
2.During amplifier working process,it cannot
be changed the work pattern of amplifiers or
the overload of speakers by random,or else,
it will damage the amplifier easily.Usually ,it
should confirm the work pattern.
4.Prohibit overload during amplifier connection.
As per rated power.
3.During amplifier working process,it cannot be
changed the plugs of every audio devices in
Simple Check and Handling
1.No power :Check whether the adapter is good
or not,whether the power plug or power wire is
2.No sound after connecting amplifier with speaker:
3.Too big noise : Check whether the connection
of the devices is good,whether it is with shield,
1.When amplifier is working , volume control
(Controlled on mixer)is from small to big,until
moderate.When close it,volume control (controlled
on mixer)is from big to small,then close it.

the plug of mixer. Or else, it will easily cause pulse
signal,then from HPPMW by amplifier, until lead to
LNB of audio,make the LNB burned and amplifier
overload then destroy the amplifier.
good or not.If not,please change the power wire.
Then check whether the indicator of adapter is
on or not,whether there is 24V DC power output,
if no,please change a new Adapter.
Check whether the speaker is overload , and
simultaneously check whether the speak is
short circuit .Check whether there is output in
amplifier after the speaker is regular.l
whether it is overload,or whether the audio signal
