【 Weak current College 】 let people have a better understanding of the power amplifier's basic settings feature---Power By 【 China power house network 】

From a functional point of view, the existing amplifier products mostly have the following features.

E-codes (Crossover): this feature set is divided into three types of choices: FULL-full-range; HP: high-pass crossover point — just let (such as 80Hz) above the frequency agreed, this setting is primarily used to high-pitched speaker in,; LP: low pass frequency point — just let (such as 80Hz) following adoption of frequency, this setting is used primarily for bass speakers. Some of these also set as the crossover point adjustable to suit different system design to set the crossover point, some are fixed at 80Hz, 100Hz, 120Hz these frequencies.

Signal input (lineinput) select: RCA signal (low voltage) and host speaker cable (high level) two input modes. Where to get good quality RCA signal input can be selected (ideal frequency response and excellent signal to noise ratio, but only if the host has RCA output), to host non-RCA output or retain the original car hosts the only choice with high level inputs of the amplifier. In addition, a lot of power amplifier products with one or two groups of signal output (lineouput), the signal is transmitted to another power amplifier, this not only saves the cost of tap tone, more can guarantee excellent sound quality, due to the different businesses in the signal output is assigned when the approach is different, so approach will make the poor sound quality.

Input gain adjustment (Gain): this knob is used to adjust the power amplifier input voltage and host transferred signal voltage reaches the ideal match status to ensure sound without any distortion.

Bridge output (bridged): when the amplifier using bridge connection, the output power can be generally increased twice, so that it needed yet another purpose (e.g., used to push the subwoofer).

Tone adjustment: a significant portion of the product set has bass (Bass) and treble (Tweeter) adjustment, can be separately in two 45Hz, 10KHz frequency attenuation, upgrading or adjustment range in between, can the 0dB-12dB replayed more fullness, deep bass, treble clarity and transparency.
