Car power amplifier is the audio power amplifier in the vehicle audio system, its role is to select and preprocess the audio input signal, power amplification, so that the electric signal has the ability to promote the sound box. Power put is a good sound indispensable composition.

Car power amplifier is the audio power amplifier in the vehicle audio system, its role is to select and preprocess the audio input signal, power amplification, so that the electric signal has the ability to promote the sound box. Power put is a good sound indispensable composition. The power put that the place that takes on host machine often cannot amplify sound current very real, want to have good music to feel so must add install power put.

Look from the function, current car power put product mostly already had the following function.

1, the Crossover
There are three options for setting this feature:
FULL - tone; HP: High Pass - only allow the frequency above the frequency dividing point (such as 80Hz) to pass, this setting is mainly used for medium and tweeter speakers; LP: Low-pass - Only frequencies below the frequency division point (such as 80Hz) are allowed to pass. This setting is mainly used for woofers. Some of them are also set as frequency division point adjustable, which can be set according to different system design, and some are fixed at 80Hz, 100Hz, 120Hz.

2. ineinput selection
There are two input modes: RCA signal (low voltage) and host horn wire (high level). In order to obtain good sound quality, RCA signal input can be selected (ideal frequency response and excellent signal-to-noise ratio, but the premise is that the host has RCA output), if the host has no RCA output or retain the original car host, only the power amplifier with high level input can be selected. In addition, a lot of power amplifier products with one or two groups of signal output (lineouput), to transfer the signal to another amplifiers, this not only can save cost of partials, more can guarantee the good quality, because different businesses in the distribution of signal output is not adopted by the practice of each different, some processing technique can make quality becomes poor.

3. Input Gain adjustment (Gain)
This knob is used to adjust the input voltage of the power amplifier and the signal voltage transmitted by the host to achieve the most ideal matching state, to ensure that the sound will not have any distortion.

4. A bridged output
When power put uses bridge type after connect a law, output power can raise commonly 2 times, make it is in need thereby when much a kind of purpose again (if use to push ultra low tone loudspeaker).

5. Tone adjustment
A considerable number of products are equipped with Bass and Tweeter adjustment, which can be promoted or attenuated at 45Hz and 100KHz respectively. The adjustment range is between 0dB-12dB, which can make the bass of the replay more abundant and deep.
