Ensuring the stability of the card package KTV audio is a major problem
faced by all KTV operators. The reason for saying this is that the card package
speaker system will cause small faults due to human or natural factors. These
faults can be said to be It is inevitable. Below we introduce some small
experiences to make the card package speaker system more stable, which is super
practical.
The biggest enemy of the card package speaker system is the guests' "do
whatever they want". No matter how high-quality it is, it is only an
entertainment toy in front of the public. Therefore, how to make the system,
especially the terminal speaker system, work continuously for a long time is a
key issue involving the interests of the enterprise and the characteristics of
the enterprise. First of all, KTV sound is different from any other kind of
sound use occasion. This is mainly because KTV does not have specialized
personnel to operate the system, so to a certain extent, even a good brand may
not always work in the best condition. That's why there is no speaker that can't
be burnt. Basically, it is believed that the power of the power amplifier is 2-3
times greater than the load. For a system operated by professionals, this is
necessary. But the KTV system to configure the power in this way is equivalent
to planting a landmine. Of course, the waiter can cut off the output of the
power amplifier at a constant, but in fact, for those singing people, the
setting of this constant can't satisfy their desire to shout at all.
It is recommended that the power of the power amplifier is more than 1.5
times the load (a single output 120W rated power amplifier with a 100W rated
speaker (a total of 40 private rooms), 4 years without a bad bass, treble
(diameter 45 titanium film) Only 4 are broken. Of course, if you don’t
"re-process" the speaker unit, it will not be as efficient as that. The voice
coil of the speaker is in a suspended state, which means that in addition to the
centering support and the frame Outside of slight contact, there is basically no
medium used to conduct heat. Therefore, how to keep the voice coil in contact
with the central magnetic column so as to evaporate the heat to the maximum
extent is the key to the stable operation of the speaker in a full compliance
state. currently has The method of adding magnetic fluid to the treble
magnetic slot is used to establish the contact between the voice coil and the
center magnetic column, but in order to maintain high sensitivity in the
professional field, this is often not done. And the woofer (moving coil) is
currently still There is no means to establish a medium between the voice coil
and the magnetic column. So at this time we need to change our attitude to solve
the problem. That is because of the situation, not to be bound by the
theoretical framework.
