美国ModWright(乐威) LS-36.5 真空管前级放大器

l  电源及放大线路部分为左右声道独立设计

l  使用两枚6H30真空管作输入级线路放大

l  选用5AR4真空管作电源整流

l  厄流圈式电源过滤电路，确保纯正供电状态

l  全新按钮式选项功能面设计，带来更优雅的外型

l  纯A类 增益及负回输电路设计

l  设多组RCA输入和两组RCA输出

l  XLR平衡输入及输出各一组

l  附设遥控功能

由最早期的SWL9.0SE胆前置为设计蓝本，再加以改良后研制出新款之LS-36.5前级，可谓对ModWright高保真前置的认真体会。整体线路以全评委为首，加上供电部分进一步增强纯净稳定而充沛的效能，及附设遥控操作，促使ModWright前级的市场地位充分提升。采用2枚俄制6H30作输入级放大及1枚5AR4真空管作稳压，加上拥有纯A类的输入增益电路设计，令LS-36.5前级声音表现非同凡响，效果出众。但这并未得设计师完全满意，相反要在最好上加以突破，衍生出旗舰分体电源式前置放大LS-36.5DM。

The LS 36.5 represents ModWright’s finest tube linestage performance, offering true balanced outputs and XLR inputs.

It follows our SE tube linestage, the SWL 9.0SE, offering a higher level of performance, aesthetics and options.

Remote volume control are standard, as is phase switching, also via remote!

The LS 36.5 takes sonic performance to the next level, offering a broader and deeper soundstage and a weightier presentation, compared to the 9.0SE.

Refinements in power supply design, voltage regulation, and driver circuit design all serve to raise the bar. Refinements in grounding, transformer coupling and shielding also yield a 2 x lower noise floor than its SE predecessor!

Those wishing to take the performance of the LS 36.5 to the next level again, have the option of adding the PS 36.5 dual-mono, all-tube external power supply. This PS 36.5 features a complete dual-mono topology, including dual tube rectifiers and tube voltage regulation circuitry.

Features:

• One set of XLR inputs
• Four sets of RCA inputs
• Two sets of RCA Main Outputs
• One set of RCA Tape Outputs
• One set of XLR balanced outputs
• Front Panel controls include: Power, Input Select and Mute, Phase (also on remote), HT/BP
• (Home Theater Bypass) and volume control (also on remote)
• Custom MWI remote control for volume, phase and mute
