●Signal source
First of all, we must know that the function of the power amplifier is to amplify and output the weak level signal source to the speaker, and then the vibration frequency of the speaker unit in the speaker is used to emit sounds of various frequencies, which is the high and medium we hear. ,bass. Among the units used abroad, Z is the famous RCF speaker.
If the signal source has noise (distortion) or some signal components are lost after compression, these noises will be amplified even more after being amplified by the power amplifier power, and the missing components will not be able to be released, so we use it when we evaluate the sound The quality of the sound source is very close to the s key.
●Audio equipment
The choice of equipment is very important. Of course, it also depends on the entertainment audio manufacturer, or the manufacturer Z that cooperates with a well-known foreign brand. The effective frequency of the speaker should be wide, the frequency response curve should be flat, the frequency response can reach 20Hz-20KHz, the power amplifier should have a high signal-to-noise ratio, wide effective frequency response, and low distortion. If the area is too small and the power is too large, a large sound pressure will cause too many reflections and make the tone muddy and unclear. Otherwise, the sound pressure will be insufficient.
The power amplifier power is 20% to 50% higher than the speaker power in impedance matching, so that the bass will be stronger and stronger, the middle and high tone levels will be clearer, and the sound pressure will not be so easy to be distorted.
●Use environment
Everyone knows that when there is no occupant in an empty room, the echo is very loud when you clap and speak. This is because there is no sound-absorbing material on the six sides of the room or the sound absorption is not enough, and the sound is reflected.
The sound is the same, if the sound absorption is not good, the sound will be unpleasant, especially if the sound is a little louder, it will be very muddy and harsh. Although it is impossible to decorate your home as a professional audition room, you can get good results by paying attention to the following points.
