Xtd系列矢量功放(VPA)可以说是在Xad系列数字功放(DPA)的基础上创新和升华的新技术、新突破，解决了数字功放功率做不大的难题。她具备了数字功放的功耗少、重量轻、体积小等优点，同时亦成功解决了成本高，生产工艺复杂等缺点，是为流动演出、固定安装等扩声系统提供全新应用理念的解决方案。该系列功放汇集了研发工程师们无限的智慧和高昂的激情，整合并优化了多项行业内的前沿技术和精良的工艺水准，令人惊异的输出功率、卓越的声音表现力以及极轻的重量，凸显了Biema音响的技术含金量和发光点：
1、在2U高度的轻便机箱中，可提供6400W（4Ω）的超高功率输出和极宽的动态范围。
The 2U portable cabinet provides 6400W (4Ω) ultra-high power output and a very wide dynamic range.
2、采用前沿的发射极（Switch-mode Power supply)输出技术，输出阻抗低至2Ω负载。
With the advanced output technology of switch - mode Power supply, output impedance down to 2Ω loading available.
3、选用美国进口“ON” Semi品牌的高效能功率管（美国ON功率管比对日本品牌功率管具有更佳的声音解析力和瞬态特性）。
The high-performance power transistors of US brand “ON” Semi are adopted (The transistors of US “ON” brand has a better resolving power and transient sounds than that of Japanese brand)
4、整机采用400块特制铜质散热片组成，比传统铝质散热器散热效率加快30%以上。能有效地保证整机的工作温度及稳定性能；同时，开关电源变压器采用日本原装耐高温材料，能有效地保障在大功率输出时变压器因过热而烧毁。
The machine is composed of 400pcs special copper radiators. Comparing with aluminum radiator, the cooling efficiency is speeded up more than 30%, which can effectively ensure the machine's operating temperature and stability; and the switch-mode power transformer is made of Japanese original heat-resistant materials, which can effectively protect the transformer from burning even in the power output and overheat.
5、专门设计的负载选择功能，可根据扬声器功率大小选择不同的功率输出与之相匹配，从而避免因输出功率过大而烧毁喇叭单元。
Designed to load selection, different power output can be selected to match the power output of the speakers, which can avoid burning the speaker components from output overload.
6、具有过载、短路、超高频、直流等多种保护电路设计，使客户在使用过程中无后顾之忧。整机的交流工作电压范围180V—260V均可正常工作。
With the protection circuit of overload、short circuit、sub/ultra-sonic and DC, the AC working voltage of the machine can be 180V-260V.
7、整机采用低压供电技术对功率管进行供电（±10V)，耗电量极低；且提高了整机的安全性能（一般功率放大器后级功率管供电都在几十伏至百伏不等）。
The Machine adopts low-voltage power supply technology to lower the power consumption and improve the safety performance (The power supply of the transistors is generally from tens of volts to hundreds of volts.)
