Important safety instructions and safety symbols
- Please read the use information(user’s manual)
- Please place this user’s manual in a secure place during the use period of the amplifier. This user’s manual is only a constituent part of the amplifier. The amplifier can only be resold with the user’s manual. Please record any change of the amplifier in written form and give it to the buyer for reselling.
- Please pay attention to all the warnings.
- Please abide by all the instructions.
- Do not use the amplifier near the water source(such as the humid indoors or near the swimming pool).
- Clean it with a piece of dry cloth.
- Do not block any air vent. Please install it according to the user’s manual.
- Do not install it around the heat source(such as radiator, heat reservoir, furnace and other equipment that can generate hut).
- Please protect the power supply cord and prevent the damage caused by trampling, squeezing, etc. Pay particular attention to the plug contact and amplifier connector.
- Please use the amplifier in compliance with the user’s manual and abide by all the suggestions before using and in use, particularly the security suggestions listed in detail in the user’s manual. The amplifier is used for amplifying the pulse audio signal, which can only be connected to the loudspeaker with indicated average impedance.
- **** Do not place the amplifier in unsteady can, table, tripod, support or table top. It may cause the serious human injuries in case of falling or severely damage the equipment.
- We can only cut off the power supply by unplugging the plug contact. Please place the plug contact in the place with easy access at random. Please unplug the amplifier if it is exposed in the thunderstorm or not use for long.
- Only qualified personnel can conduct the maintenance work.
Maintenance in case of the following circumstances.
- Power supply cord or plug damage
- Liquid or objects splashing or falling into the amplifier
- Amplifier exposed in rain or humid air

Installation and connection
Power supply
Disconnect the power supply for the installation or connection of the
amplifier. Please connect the amplifier to the corresponding AC circuit and
outlet according to the requirements of second line indication of the
nameplate.
Applicable to
the reference nameplate of 110 V- 50/60 Hz power supply.
Notes: We can only select fixed 220V operation. It is prohibited to use the
amplifier for long term beyond the specified range(rated voltage 10%) because
it will affect the overall performance.
Notes: The rated power consumption and supply current consumption is 1/8
of the rated output power, namely, 2 x 150W is measured in circumstance of
800W 2. Pink noise represents the typical music signal. It depends on the
valid output power. The power current and power can reach quite high(low)
value.
Turn on/off switch
“ON/OFF” switch is rocker switch, which is located in the right side of the
front panel. Turn on the amplifier and push the switch upwards. It starts by
activating the surge current limiter. Wave clipping and signal LED will be
lighted for several seconds during power connection period. Please push the
switch downwards in order to turn off the amplifier.
Notes:
This switch does not disconnect the amplifier from the power supply cord.
The switch starts by activating the current limiting function. Immediately
after the power amplifier is connected to the power supply, a voltage is
supplied to the line filter and to the input of the fusible controllable
rectifier. The amplifier can only be disconnected from the power supply by
physically pulling out the power plug. So the power plug must be easily
accessible. Pull the power plug from the amplifier during thunderstorms or
when not in use for a long time. Alternatively, you can turn off the amplifier
by disconnecting all external electrodes from the power supply.
The amplifier will automatically restart after power restore and maintain all
the settings before shutdown if the power supply is disconnected when the
amplifier is turned on.
Introduction to cabinet installation
Install the amplifier front rack with four screws and cushion ring. We can use
19″ installation component for the fixation of the amplifier because the
amplifier is movable.
