AELIUS II



Aelius II是胆/石混合立体声功率放大器,仅使用两个增益级,没有负反馈,驱动世界上的任何低灵敏度扬声器均能产生无与伦比的透明度和音乐感。
第一增益级用在单端A类中操作的电子管,耦合到输出级的变压器实现功率放大。通过使用变压器,我们避免使用额外的增益级,因此保持了音频信号的透明度和纯度。
 
为此,在宽频范围的听音测试和测量下开发了带宽(10-75KHz)变压器。变压器的带宽也定义了放大器的带宽。
在Aelius II中,增加了最近开发的输入变压器,其进一步扩展了信号传输的纯度。它还为放大器提供了平衡输入的机会,增加了使用更长互连讯号线的通用性。
输出级使用相同极性的组件(N通道),工作在相同的波形中。放大器的输出是对称的。
电源供应的设计中也非常讲究。它使用大电流电感线圈进行平滑和安静的电源处理。
Aelius II绝对是一个革命性的产品,具有独特的优势,具备精致和透明的音色和超强控制力以驱动扬声器。

 Aelius II is a push-pull hybrid monoblock power amplifier using only two gain stages with no overall feedback providing power to drive real world speakers with unmatched transparency and musical involvement.  

 

The first gain stage is implemented with a valve, operated in single-ended class A , transformer coupled to the output stage. By using a transformer we avoid using an additional gain stage, so transparency and purity of the signal is preserved.

For this purpose a wide bandwidth (10-75 KHz) transformer is made, developed under extensive listening tests and measurements. The bandwidth of the transformer defines also that of the amplifier.

In Aelius II a recently developed input transformer is added that extends the purity of the signal path even further. It also gives the opportunity of a balanced input in the amplifier, adding versatility of using longer interconnect cables.

The output stage uses components of the same polarity (N-channel), working in the same topology.  The output of the amplifier is symmetrical so both output connectors, plus, minus, carry signal in opposite phase.

Great attention was paid also in the power supply design. It uses high current inductors for smooth and quiet filtering.

Aelius II is most certainly a revolutionary product having a unique set of features, refinement and transparency with power and control over the speaker.
