1.Use CD, MD not VCD, MP3: the host still choose CD, MD or DVD if only to play sound .VCD sound quality is poor, it is best not to use;MP3 belongs to the compression format, although the increase of sound quality processing circuit, but the sound quality is still not as good as CD;DVD's sound quality is close to CD's, but overall, it isn't as good as CD's.MD's sound quality is similar to CD's, but the sound is slightly harder.CD records to choose genuine, with the disc printed with "DDD" the best, this CD records produced sound quality is good.
2. The host should choose the signal without any modification of the model.The waveform of the signal is distorted after modification, so the music isn't ideal.The "original" host should preferably have no graphic equalizer, field effect (e.g. theatre, square, studio, etc.).After modification of the field effect, the original signal will change and lose its original sound quality.
3. Choose 24bit not 1bit: choose the model to look at the frequency response index, without any additional modification of sound quality function.CDS sold at audio stores have 20 bit and 24 bit labels on them.20bit and 24bit high parsing power to make the music fully displayed.Ordinary audio for more than 1bit, the use of high - level audio bit.Only when it is played on such a machine can it show its delicacy.
4. Choose high power without distortion: choose high output power if the host directly promote the loudspeaker.Now the host output power is generally in 4×50W, mainly to reduce distortion.If the host's front output is used, the output level should be high in order to improve the signal-to-noise ratio. The output level is generally 2V, and it is best to choose 4V output.In a sound system, the output power of host or result amplifier is bigger, show the audio linear range that they can control is bigger, so drive loudspeaker ability is stronger.And the result put of small power causes the distortion on sound easily not only, can bring about to burn more result put or horn coil, in the end spent big effort and can't get ideal music effect.
5. Sound quality of natural playback principle: the so-called playback refers to the music played out of the original music changes little.The smoothness of frequency response curve is an important index of sound quality evaluation.The smoothness of the curve is the voice that points to every register is loud size, the voice of every register is consistent, the smoothness of its curve is good, smoothness is better, the effect of hearing and hearing is better.
