Lovers in general, to right Sound Evaluation system or tuning Although there are many difficulties, but there are some rules to follow, here is some of my experiences.
We can use Headphone To section examination CD Machine and Amplifier . The reason why the use Headphone Because one can avoid the annoying interference factors room; two cents on the subtle signals completion of the current reduction of fiber capacity; 3, with high fidelity.
First evaluation CD machine. If you listen with headphones the sound does not feel right out, then the CD players and records are likely to be "suspects." But in general we find a test disc should be no difficulty, therefore, take a test disc to test the CD, is a common practice. Not use a machine to test the CD film CD.
To find records, can be sorted out in a variety of media comment on a certain consensus, recognition, high fidelity, detail-rich as the trial record to determine Yindie. Of course, the test should include multiple types Yindie. For example there are various voices of the strings and piano track used to test the frequency response of the symphony can detect a sense of positioning, percussion and electric bass and bass can test the speed of a sense of intensity of feeling. It should be noted class sound recordings should be minimal use of electricity as a trial Yindie, because most people are familiar with low level, it is difficult to establish reference.
With test disc, you can use headphones the sound quality test CD machine characteristics and the degree of fidelity.
Audition, should be very careful to be aware in advance to hear the sound and record the contents of different comments on the degree of contrast. If very different, then further study of CD machine is not high fidelity. Instead a small difference, it means fidelity.
Identified CD machine, the next step is the assessment Amplifier .
Amplifier output power as much, and headset bearing power is small, so the need for a resistor attenuator. Conditional friend can make yourself.
Adjust the volume, moderate volume of the headset.
As the CD machine has been tested, and also show that the CD the system "size" has been been measured, and its quality features have also been very clear, and then only when the amplifier evaluation and previous CD audio systems sound contrast on it. Evaluation method is still: a big difference, low fidelity; the other hand, good fidelity. If it is intended to prepare high-fidelity system, then use the above approach is more practical and convenient. Thus, the system is also considered complete with a half.
For a certain basis or practical ability of e-Shao You can also make a simple switch, the output of the CD machine and switch between the output amplifier with audition, so sound can be compared more directly and quickly.
, Of course, to test the amplifier with headphones, sound quality can only evaluate the fidelity, while the amplifier and Speaker Co-ordination between the power factors, need to be considered separately.
Last is Speaker Choice. Of course, this time the mission of headphone listening can be considered completed.
Speaker is very easy to highlight the individual components, sound different and more and less similar. In theory, high fidelity speakers should be selected grades, but the price to be more expensive.
In fact, different Shao You will have different preferences or focus area. Therefore, the selection of speakers can not achieve the "thorough." As for the speaker's characteristics, you can get information from a variety of media, from selecting the type generally to your taste. Selected, you must also use their own CD players and amplifiers set about trying to match speakers, listen to how the specific sound.
Some Shao You already have a stereo, but he's not satisfied, do not know from which part of the problem, so might as well do it with a headset test.
