Three strokes teach you to buy active audio
Whether or not the styling will give you a beautiful enjoyment is enough for you to have a bright feeling and to put it down, then see if the color, size, etc. are in accord with personal preference. Of course, once you have selected it, you must pay attention to the following points:
1. Whether the entire surface is smooth and smooth, and the front and rear shells must not be allowed to have any difference or step;
2. Is there a "3C" note on the machine?
3, the box should be tight and even at the cracks, knobs and sockets with the box to be moderate, indicating that the mold, injection molding skills;
4. The subtleties show true merits. Every face, every line, and every clear corner must be exquisite and smooth. No ambiguity;
5. Observe the marks on the front and back surfaces that are engraved or screen printed. Be clear, correct, smooth and even;
Second "touch"
1, touch the surface of the box, combined with the eye view, we can see the level of production of the box and the level of surface treatment;
2. Rotate the knobs and switches to see if there is a feeling of friction and bumps. A good potentiometer should feel smooth, even, and have a proper resistance. Too light, heavy, or uneven is not desirable;
Three "listen"
1, the speaker is connected, turn on the power switch, adjust the knob to the maximum position (clockwise), listen to the noise emitted by the speaker, the normal situation, the human ear away from the speaker about ten centimeters, should not be noticeable, otherwise noise Too high
2. Finally, adjust the volume to the maximum and minimum states respectively and turn off the test. A good machine, at this time the impact of sound ("pao" sound) is not obvious, if the impact is too large, easy to damage the speaker, you should not buy. Consumers pay attention to the above issues at the time of purchase and believe that they can buy suitable speakers that are satisfactory.
