注意： Note:

企业设计系列型号放大器因为功率不一样，会在输出电压、重量、耗电量上有些不一样，具体参数请参考下面数据表：
Designed a series of models because of the power amplifier is different in the output voltage, weight, power consumption is a bit different, specific parameters refer to the following table:

注释 Notes
峰值因数(CF)控制 Crest factor (CF) control
峰值因数：信号波形电压峰值和电压有效值之比。
Crest factor: the voltage waveform peak and RMS voltage ratio.
峰值功率： Peak power:
放大器短时间输出最大功率，注意此数值一定不可大于扬声器额定能承受峰值功率，不然易造成扬声器机械损坏。
Short-term maximum power output of the amplifier, note that this value must not be larger than the speaker can withstand a peak power rating, otherwise easily lead to mechanical damage the speakers.
最大不失真功率： Maximum distortion power:
输入一个要求正弦信号,在许可失真范围内，放大器能够输出最大有效值功率。
Enter a prescribed sinusoidal signal within the allowed distortion, the amplifier can output a maximum RMS power.
有效值功率：RMS Power:
在一个要求时间段里,放大器输出能量总和和时间比值,这个参数能够真正反应放大器传输给扬声器平均功率，注意此数值一定不可大于扬声器额定能长久承受功率，不然易造成扬声器过热损坏。
At a specified time period, the amplifier output energy ratio between the sum of the time, this parameter can really respond to the speaker amplifier average power transmission, attention must not be greater than this value long-term exposure to speakers rated power, otherwise easily lead to the speaker overheating damage.

峰值因数高信号压降低，音质好，峰值因为低于2.8时音质已劣化到无法使用：
High signal voltage crest factor reduction, good sound quality, the peak is lower than 2.8, because the sound quality is not degraded to use:

峰值因数大信号动态裕量大、音质好
Large crest factor signal dynamic large margin, good sound quality

峰值因数小信号动态裕量小、音质差
Small-signal dynamic crest factor margin is small, sound quality is poor

峰值因数为4信号有效值功值大约是最大不失真功率1/8，峰值因数越低则放大器发烧越多，扬声器更轻易损坏：
Crest factor of 4 RMS power value of signal distortion is about the maximum power of 1 / 8, the lower the crest factor is the more heat amplifiers, speakers, more prone to damage:

发烧小、动态大、扬声器易产生机械损伤
Heat a small, dynamic large, easy to produce mechanical damage speakers
发烧大、动态小、扬声器易出现热损伤
Heat large, dynamic small speaker prone to heat damage
峰值因数低信号平均声压大，峰值因数高信号平均声压小：
Low crest factor signal averaged sound pressure large, high crest factor signal average sound pressure is small:

峰值因数低应用方案因为较轻易取得大平均声压，所以可降低器材用量。降低系统成本。峰值因数高应用方案系统成本高，所以CF>5.6应用方案多用于家用高保真或录音监听等领域。
Applications with low crest factor for easier access to large, the average sound pressure, thus reducing the amount of equipment, reduce system cost, high crest factor system, the high cost of applications, due to CF> 5.6 of applications for home hi-fi or multi- recording monitoring and other fields.

系统成本高 System costs are high
系统成合适 System into the appropriate
系统成本低 Low system cost

家用高保真 录音监听 休闲音乐等
Household high-fidelity audio listening music, leisure
酒吧 DISCO 室外演出 体育馆等大型演出
DISCO outdoor performance sports bars and other large performances

综合起来，我们认为系统峰值因数为4时是一个很好应用状态，据此我们设计了两个系列放大器，B系列放大器在多数负载情况下可能使用CF>2.8信号，在驱动低阻抗负载时则适适用于CF>4信号，譬如两个通道全部驱动2 OHM，桥接4 OHM和并联驱动1 OHM三种情况，而C系列放大器在全部许可负载情况下全部能够使用CF>2.8信号。
Together, we believe that the crest factor of 4, the system is a better application of the state, thus we designed two series of amplifiers, B series, the load in most cases the amplifier may be used CF> 2.8 signal, the driving low impedance load is applicable to CF> 4 signals, for example, both channels driven 2 OHM, 4 OHM, and parallel bridge driver 1 OHM three cases, while the C series amplifiers allows the load in all cases you can use the CF > 2.8 signal.

超出这些要求使用，放大器有可能自动调整音量，提升峰值因数。
Beyond the use of these provisions, the amplifier may automatically adjust the volume, increase the peak factor.
