美国ModWright(乐威) PH150 分体电源式真空管MC/MM唱头放大器

乐威Modwright设计师Dan Wright从最早期推出的唱放SWP 9.0SE已经在市场取得很多人的关注和爱戴!事隔多年后,今天Dan再为此唱放市场注入新血,研发出比已往的9.0SE更上一层楼的PH150真空管唱放。

 

唱放本身以分体电源设计,属高级唱放的设计其准,在宁静度相对可加分。MC放大部份是采用两枚(左/右声道)瑞典最有名气的火牛制造商LUNDAHL的LL1660S作升压牛。线路上,选用两枚6C45电子管给输入电路,另外两枚6922管于主电路负责放大部份。
增益范围达72dB(MC),而且面板上设有-6及-12dB衰减以配合不同输出唱头的要求。另外,MM输入增益最高为57dB。

 

置于供MC用的输入阻抗有6组分别10, 50, 100, 200, 500和1KΩ可在面板上调校,而MM输入就有:0, 100, 220, 330, 470及690pf六段容抗值调节。


输出设有RCA及XLR平衡两组可供选择,还有在唱放都会常用的正/反相设换也兼备,按扭设于输出插座的旁边。

 

声音特性绝对是乐威的一贯有胆味又有分析力,而且加入了一份一般唱放或黑的胶系统中难以在起高音压和动态情况下,能保持原有演译的喜悦!绝对是有潜质的胆唱放。

 

 

 

We are pleased to present the new PH 150 Reference Tube Phono stage with on-the-fly loading and attenuation controls.

The PH 150 is an all tube-transformer coupled design with external SS PS 150 power supply.

Max gain = 72dB. MM/MC, Stereo/Mono, RCA and XLR (fully balanced outs) and rear phase toggle.

Resistive and capacitive loading may be adjusted on-the-fly via front panel controls.

Gain may also be adjusted in 0, -6dB and -12dB steps, on-the-fly for both MM and MC inputs.

Inputs may also be switched on-the-fly, from MM to MC carts for tables with multiple arms.
