First of all -style, different amplifiers must be paired with speakers of
the same style, which can not only play the performance of the audio amplifier
to the extreme, avoid distortion, etc., but also reduce damage to the speaker.
If, different styles of amplifiers with different styles of speakers, the
effects are light and unscrupulous, and the equipment is damaged.
The second point is that everyone is most concerned about the power
matching of the speaker and the power amplifier (host). Now in the industry,
there are divergent and indifference in this respect. Some say that the rated
power of the power amplifier must be greater than the rated power of the speaker
(equal) to push the horn; some say that the rated power of the power amplifier
must be greater than 30%of the rated power of the speaker. In this way, the horn
can be pushed well, otherwise it may burn the horn when it is big;
Regardless of the above statement, let's take a look at the physical
meaning of the rated power of the horn and power amplifier first:
For the amplifier, the rated power generally refers to the valid value
(RMS) power that can be continuously output.
For the horn, the rated power is called the power that can bear the power
of this value for a long time without damage.
The analysis from the above two points is not the rated power of the
amplifier must be greater than the rated power of the speaker. The driver of the
speaker is difficult to determine by its sensitivity and impedance
characteristics. The amplifier with the output power less than the rated power
of the speaker. As long as the volume is not suddenly increased, the power
amplifier controls the linear work range (no wave of waves) will not cause
burning speakers; The speaker, as long as the power amplifier's output power is
controlled within the range of the speaker, the speaker will not cause overload
damage. Therefore, in order to protect the equipment, the most important thing
is that the tunner must set the input sensitivity level of the amplifier when
the tunnel is tuned.
However, if you want to discover the best sound quality of the horn and
amplifier, I suggest that it is best to choose the Grapho's power amplifier with
the jazz's speaker, and try to choose the same brand. Jazz engineers will
develop the corresponding amplifier based on their own speaker performance, and
to technically can play the limit performance of the speaker. The Jazz's sales
staff will design a reasonable solution based on the user's use venue, user,
general budget.
