The sound in the device depends on the number of channels; it can be of two types: Mono, Stereo. A single channel device provides mono sound; with two, respectively, stereo. The main difference between stereo and mono is the “volume” that stereo has. Each speaker in the column is responsible for the low or high-frequency band. With the Top Quality Electronics this is the best opportunity that you can have.
Tip: Refuse to purchase a device in which the speakers are smaller than the bands.
Food and work time
In many embodiments of the device, there is a built-in battery that allows you to use the gadget regardless of the electrical outlet. Therefore, choosing a column, pay attention to its battery life. But in most cases, the manufacturer measures this indicator is not at the maximum volume of the sound. Thus, the actual battery life is likely to be lower than stated.
Instrument power
The average gadget has a power of 16-20 watts. Columns of a higher price category have 60 watts.
Dust and moisture protection
These functions are nice bonuses that can save the gadget from various domestic troubles. Columns equipped with this protection have an IP index; protection level is marked with numbers from 1 to 10. It is important to take into account all the above parameters, but still, acquiring a portable speaker, focus primarily on your feelings, because no technical recommendation can affect your hearing.
Any modern house is stuffed with various electrical appliances. TV and refrigerator iron and computer, stereo and washing machine, food processor and light bulbs in the chandeliers. People use these devices daily. Therefore, they often forget about caution. Before going to bed or before leaving the room, all electrical appliances that do not need continuous power, for example, and a refrigerator must be disconnected from the mains. “click” the remote control of a TV, computer or music center is not enough.
Often, such devices are left in “standby mode” it seems to be turned off, but the indicator is lit on the panel. In this state, part of the instrument’s nodes, including its power supply, is under mains voltage. In the event of significant voltage fluctuations in the network, long-term continuous operation of the power supply unit, the device may fail and short circuit. If the manufacturer of such a device decided to save money and instead of the fuses, it simply soldered the jumper wires, or it was repaired by an unqualified master, it is possible not just breakage, but also fire.
Therefore, make it a rule not only to turn off the devices but also to pull out the plugs of the cords from the sockets.
