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.  Always be sure to have all levels at minimum when connecting or disconnecting 

audio sources from the inputs, especially when MIC is selected from the MIC/
LINE switch.  Failure to do so may cause the amplifier or speaker to go into a 
protection mode or even cause damage.

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 40°C. 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 become green 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 soon resume working. When the amplifier 
returns to normal temperature the power indicator will return to blue and you 
may turn the volume up to a safe level.

10.  If the line voltage to the amplifier is too low, the low voltage protection function 

will be activated. The power light ring will change from blue to green. 

CAUTION: JBL is not liable for damage that results from overdriving other 
system components.
