Most types of audio amplifiers have a power supply built in. That means that the power cord is connected directly to the amplifier. All you need to do is to connect the power cord with an outlet and you will be all set. However, keep in mind that some products are designed for different voltages. That is because some countries have a 120 V power supply voltage while others work with more than 220 V.

In that case you might have to flip the switch depending on the mains voltage so that the power supply will work properly. Some power supplies are not able to tolerate the wrong voltage and thus checking the input voltage is crucial. However, some amplifiers don’t come with their power supply. Instead, they will have a power connector at the rear which requires a specific voltage.

In order to operate such …

The price of electricity has risen steadily over the last decades. Therefore, for cost reasons it is always good to think about conserving power. However, conserving power also serves in protecting the environment. Let me talk about how you can save money by conserving power when running electronic appliances.

As you may notice, most products have a standby mode. It standby mode means the device is ready except commands through a remote control but is not doing anything otherwise. You can typically tell whether a device is in standby by looking at the light typically is on. However, many people don’t realize that devices also use power when in standby. In fact, all the TV sets in the United States together running in standby need an amount of power for which a dedicated power plant is required. Therefore, the best way to minimize power consumption is …
