Some Tips for Using Audio Amplifiers

Just like any other audio equipment, it makes sense to treat audio amplifiers well in order to prolong their lifetime. Just follow these tips and you amplifier should last a long time and provide best performance.

Amplifiers can easily be damaged during the installation. First of all, make sure that the voltage of the amplifier is set to the correct voltage that your power outlet provides. Some amplifiers have a switch to select either 110 V or 220 V AC voltage. Never connect an amplifier which is set to 110 V to an outlet that has a voltage of more than that because that would irreparably damage the power supply of the amplifier and possibly the amplifier board itself.

I recommend to connect all of you speakers to the amplifier before switching on the amplifier. This will prevent short-circuiting the amplifier outputs and thus causing damage to the amplifier power stage. If the amplifier is active then connecting speaker cables can accidentally short the outputs. Even though many audio amplifiers have a protection circuitry built in, nonetheless short-circuiting the outputs is never good idea. So make sure that everything is set up properly before turning on power to the amplifier.

When operating the amplifier, first of all turn the volume control to minimum. That will prevent overloading the amplifier. Then slowly increase volume until you reach the desired volume on your speakers. Never set the volume to maximum right away because that can easily damage the amplifier as well as your speakers. When you switch on the amplifier, they may be a plopping noise which can damage the speakers. However, if the amplifier volume is set to minimum, the plopping will usually be less severe.

Also, never connects cables to the amplifier while it is running. Connecting cables can also cause very loud plops which most likely are going to damage the speakers. Like I said above, set up everything before turning on power to the amplifier. Also, when installing the amplifier, make sure it is placed on the solid surface and all the cables are tucked away neatly. If you accidentally tripped over wires which are connected to the amplifier then either the amplifier connectors can break or the amplifier can be pulled to the ground.

Also, allow plenty of ventilation around the amplifier because there’s plenty of feed that needs to be dissipated. Without sufficient airflow, the amplifier can sustain heat damage. Also, never place any liquid on top of the amplifier because if any liquid gets on to the circuit board, the amplifier would break most likely.
