D2Audio公司推出新型7路每路输出125W的数字放大器模块 XRT127-7,是第一个满足THX Ultra2放大器性能标准的数字放大器,用于音频/视频接收器.这种紧凑的功能极端强大的放大器模块满足当今最好的音频放大器的性能水平.该放大器把新型D2Audio CXT350"音频级"开关电源组合起来,从而得到了杰出的音频性能和优异的声音.
全球许多顶级消费类电子产品采用THX资格证书的终端产品都能给终端用户提供优异的收听体验.直到今天,所有这些产品都是采用传统的线性放大器,而没有数字放大器能提供满足THX资格证书所需要的性能.消费类电子产品公司能采用D2Audio的XRT125-7放大器模块来开发引人注目的音频/视频接收器,得到最高级的音频性能和质量,更轻和尺寸更小的终端产品.采用D2Audio的智能技术,它们还具有许多独特的性能和优点.
THX Ultra2需要优异的性能,并能提供:
能最严格的条件下提供极好水平的峰值功率,
在所有的功率电平都能提供超低的失真(THD+N)电平,
不管扬声器的阻抗负载如何,都能维持所期望平坦的频率响应,
提供非常优异的信噪比(SNR).
XRT系列产品能提供高性能的音频性能:
125Wx7路,所有通路驱动,
信噪比/动态范围大于114dB(未加权,20Hz-20KHz),
THD+N小于0.15%(125W,20Hz-20KHz),
THD+N小于0.025%(1W,20Hz-20KHz).
据说还有可以集成在HTPC中的功放：
The XPC100/50/25-5/7 (XPC100-5 shown at right) complete digital amplifier reference design integrates two D2Audio DAE-1 (Digital Audio EngineTM) ICs (D2-81433-LR), HD Audio bus interface, options for 100W, 50W or 25W (RMS, 8Ω) output stages (reference design dependent), 5 or 7 channel board layout support, output filters, subwoofer line out, USB 1.1/2.0 communication interface (enables optional Canvas support), optional integrated DC-DC converter with traditional +5V/+12V interface for direct connection to a standard ATX power supply, & support for direct FET heatsinking. Completely designed for ease of compliance with standard end-product requirements such as UL, CSA, & RoHS.
