3.0 Operation
3.1 Precautions
Your amplifier is protected from internal and external faults, but you should still take
the following precautions for optimum performance and safety:
1.
Before use, your amplifier first must be configured for proper operation,
including input and output wiring hookup. Improper wiring can result in serious
operating difficulties.
For information on wiring and configuration, please consult the Setup section of
this manual.
2.
Use care when making connections, selecting signal sources and controlling the
output level.
3.
Do not short the ground lead of an output cable to the input signal ground. This
may form a ground loop and cause oscillations.
4.
WARNING: Never connect the output to a power supply, battery or power main.
Electrical shock may result.
5.
Tampering with the circuitry, or making unauthorized circuit changes may be
hazardous and invalidates all agency listings.
6.
Do not operate the amplifier with the red Clip LEDs constantly flashing.
7.
Do not overdrive the mixer, which will cause clipped signal to be sent to
the amplifier. Such signals will be reproduced with extreme accuracy, and
loudspeaker damage may result.
8.
Do not operate the amplifier with less than the rated load impedance. Due to
the amplifier's output protection, such a configuration may result in premature
clipping and speaker damage.
9.
Use the amplifier in a well-ventilated environment and do not use it in ambient
temperature conditions in excess of 40ºC. Failure to do so will result in the auto
disconnection from power supply, and the overheat auto protection function will
be activated. The power indicator will be turned off and there will not be any
audio signal coming out of the amplifier. In this case, turn down the volume to
the minimum, and the amplifier will resume working. When the amplifier returns
to normal temperature then you may turn the volume up to the required level.
10. If the line voltage to the amplifier is too low, the low voltage protection function
will be activated. The power indicator will be turned off.
CAUTION: JBL is not liable for damage that results from overdriving other
system components.
