M22 V2

Stereo Power Amplifier

Connect to the emotion of live performance through detailed sound with amazing control and transparency. This is the M22 V2. It is easy to find amplifiers that can excel in one or two areas, but the M22 is truly an amplifier that does everything well. Wide open-loop bandwidth, extremely low-phase shift, almost non-existent noise, harmonic and intermodulation distortion independent of load (load invariant), high current capability, low output impedance (high damping factor) uniformly at all audible frequencies—it all adds up to incredible performance. You just have to hear it to feel it.

通过细致入微的声音，以惊人的控制力和透明度来连接现场表演的情感。这就是M22 V2。很容易找到能在一两个方面都有出色表现的放大器，但M22确实是一款无所不能的放大器。宽广的开环带宽、极低的相位偏移、几乎不存在噪声、不受负载影响的谐波和互调失真（负载不变）、高电流能力、在所有可听频率上均匀的低输出阻抗（高阻尼系数）--这一切都让人难以置信的性能。你只需要听到它，就能感受到它。

Hybrid Digital Amplification

The M22 is using the latest nCore™ amplifier technology licensed from Hypex to provide a nearly ideal amplifier with distortion below measurement, ultra-high damping factor, and unconditional stability with any speaker. Tight, detailed sound with amazing control and transparency gets the best performance available. With nCore, Hypex has refined their UcD concept to new levels of perfection by improving the modulator for more accurate feedback subtraction and PWM generation. The all-discrete driver and output stage have also been improved for lower open-loop THD as well as lower idling losses, normally conflicting requirements with conventional IC driver circuitry. An added control loop incorporating an integrator with adaptive clipping enables 20dB more feedback to be used across the audio band because of its extremely low-phase shift resulting in a dramatic reduction in distortion across the audio band. This is added to UcD’s already amazing characteristics of load invariance and high current capability, common characteristics of great-sounding amplifiers.

混合式数字放大

M22采用了Hypex公司授权的最新nCore™功放技术，提供了近乎理想的功放，失真度低于测量值，超高阻尼系数，无条件稳定地使用任何扬声器。严密、细腻的声音与惊人的控制力和透明度获得了最佳性能。通过nCore，Hypex将其UcD概念完善到了新的完美水平，改进了调制器，使反馈减法和PWM生成更精确。全分立驱动器和输出级也进行了改进，以降低开环THD和空载损耗，这通常是与传统IC驱动器电路相冲突的要求。新增的控制环路集成了一个自适应剪接的积分器，由于其极低的相位偏移，使得整个音频频段的失真显著降低，从而使整个音频频段的反馈量增加了20dB。此外，UcD还具有负载不变性和高电流能力等令人惊叹的特性，这些都是出色的放大器的共同特点。

Effortless Power

Employing the latest generation of digital PowerDrive™, the M22 offers a minimum of 300W per channel with amazing reserves of dynamic power at lower impedances. The M22 is capable of >400W dynamic power per channel even in 8 ohms, >700W in 4 Ohms, and 1,000W in 2 ohms. Need more power? Select Bridge Mode and the M22 offers 950W at 8 Ohms in Mono. It can effortlessly power any loudspeaker to live performance levels with amazing efficiency and low power consumption. Control for PowerDrive is derived by sensing the average output power, applying a time constant, and then cleanly hard clipping the signal thus limiting it to the rated continuous clipping power over a sustained loading. By controlling the power envelope maximum clean power is obtained for every operating condition.

不费吹灰之力

M22采用了最新一代的数字PowerDrive™，在较低的阻抗下，每声道最小功率为300W，动态功率储备量惊人。即使在8欧姆下，M22的每通道动态功率也能达到400W，在4欧姆下能达到700W，在2欧姆下能达到1000W。需要更多的功率？选择桥接模式，M22在单声道8欧姆下提供950W的功率。它可以不费吹灰之力地将任何扬声器的功率提升到现场表演水平，效率高、功耗低。PowerDrive的控制是通过感应平均输出功率，应用一个时间常数，然后对信号进行清洁的硬剪接，从而将其限制在持续负载的额定连续剪接功率。通过控制功率包络，在各种工作条件下都能获得最大的清洁功率。

Perfecting Performance

The output stage is only one of several circuits in the amplifier, and each must complement the other to obtain optimal performance. The amp is DC coupled throughout, from input to output, there is no capacitor in the forward signal path. Yet, it has a beneficial 12dB/octave roll-off below 2Hz. It does this using a unique circuit topology that is functionally a forward servo. It is however not a servo in the traditional sense as it does not measure DC at the output and send back a correction signal. Instead part of the input signal is fed to a side chain with a second order low-pass filter. The output of this is subtracted from the forward signal input to the second stage thus rejecting DC.

完善性能

输出级只是放大器中的几个电路之一，每个电路必须相互补充，才能获得最佳性能。该功放从输入到输出都是直流耦合，在前向信号通路中没有电容。然而，它在2Hz以下有12dB/倍频程的滚降。它使用独特的电路拓扑结构实现了这一点，在功能上是一个前向伺服。然而，它不是传统意义上的伺服，因为它不在输出端测量直流并发送修正信号。相反，输入信号的一部分被送入一个带有二阶低通滤波器的侧链。其输出从输入到第二级的正向信号中减去，从而拒绝直流。

Clean and Dynamic

The performance of the entire signal path is critically dependent on the power supply; in this case a well regulated, but not too tight, custom switch mode design. This allows maximum dynamic power, very high current yet with very low distortion. Secondary supplies are individually regulated and decoupled at each opamp for lowest possible noise and maximum dynamic range.

清洁与活力

整个信号通路的性能关键取决于电源；在这种情况下，电源是一个调节良好，但又不至于太紧的定制开关模式设计。这样可以获得最大的动态功率、非常高的电流和非常低的失真。次级电源在每个运算放大器上都有单独的调节和解耦，以实现最低的噪声和最大的动态范围。
