OPERATION
1. Check that all connections are correct and the backplate voltage is the same as the
mains voltage.
2. Check that the audio output voltage is equal to the speaker input voltage.
3. Check whether the total impedance of the system is greater than or equal to the
norminal impedance of the amplifier.
4. Make sure all connections are correct and that the voltage on the back plate is the
same as the mains voltage. Plug in the power plug.
5. Turn on the signal source,and adjust the sensitivity selecion switch to make the
sensitivity is accordance with the signal source.
6. Put the gain control to the minimum,turn on the amplifier.The power light turns on,
the protect LED dies after 3 seconds,then turn the gain control to the appropriate
position,the signal light turns on.The amplifier comes into work mode.
7. Adjust the gain control to suitable position, which make clip indicator LED twinkle
but not light for long time.
8. Please turn off amplifier first and then shut off the signal source.
Overload and short circuit protection:
FPA series has short circuit protection of automatic recovery;the amplifier starts to
work again automatically after solving the trouble. The fan of this series speed varies
automatically to maintain safe internal temperature.
Overheat protection:
If the inner temperature surpasses 100℃, the overheat protection circuit works,
disconnecting the load from that channel. When the temperature cools under 100℃,
the unit starts to work again.
