Speaker and amplifier use notes

Amplifier and speaker compared to cheap beats the speaker out of the situation will be more than the amplifier, because the speaker to maintain the treble part of the life of the parts with the air humidity and the impact of current strength, prone to problems, then beats by dre cheap we say that these devices easy Where the fault occurred. Amplifier and speaker compared to the speaker out of the situation will be more than the amplifier, because the speaker to maintain the treble part of the life of the parts with the air humidity and the impact of current strength, prone to problems, then we say that these devices easy Where the fault occurs: 1, power amplifier and speaker between the line connection: the amplifier cheap beats by dre signal line to try to use the balance line, if the system has more than one amplifier, the better use of signal amplification distributor to allocate enough, no attenuation Of the signal line for each amplifier to use alone, this can reduce system noise, reduce hidden dangers, improve signal to noise ratio. At the same time must pay attention to the quality of the speaker line and line and line connection, as far as possible with relatively thick, short beats by dre cheap copper dedicated speaker line, the connection must also pay attention to distinguish between positive and negative and avoid short circuit, especially professional four or four core Above the speaker plug, inside a few terminal is very small, wiring must pay attention.

2 power matching: In general, the power amplifier power is greater than the speaker power, conventional power amplifier power than the speaker power more than 20%, and with a small power amplifier to push high-power speakers, the amplifier will lead to overload, resulting in Harmful to the speaker current, this time the speaker unit is easy to damage.

3, the impedance matching: the current professional speaker system used in the amplifier are generally set resistance, the general power amplifier in the work of the most, some audio division like a amplifier to push more than 2 speakers, then we must Note that the impedance of the speaker, and more than the speaker in parallel when the impedance will be reduced, if less than 2 锟斤拷 when the amplifier is very easy to damage at this time, this short circuit should work to avoid the use.

4, after the amplifier sometimes have a lot of switch, such as: monaural mode of operation, stereo mode, bridge work mode; there are level adjustment switch, signal frequency switch, etc., we must pay attention to Look at these switches, adjust the amplifier to the correct or you want the work of the state, otherwise it may cause unpredictable failure.
