TRD3 is a new HIFI desktop digital decoding amp integrated machine 2014 TCG launched, both the Android /USB/ fiber / coaxial decode interface, asynchronous decoder is a high quality up to 32bit/192k, with built-in thousands yuan (Headset amplifier can push 300 ohm HIFI within the Headset), showing TRD3 let you carefree enjoy music strength.
TRD3 uses an exclusive patent power module, USB decoder is not comparable to the excellent quality of power supply, adopts CM6631A+AKM4390 digital interface combination of rave reviews, independent left and right channel filtering, comparable to the balancing circuit. A key to full function MCU control is both practical and worry (with memory). Constructed using national famous electronics components, plus the TCG team of excellent circuit design and tuning, is your ideal choice of high-quality music appreciation!
Listen to science and technology company has R & D and production of the HIFI sound system for several years, as the name suggests is to "the enjoyment of hearing" for science and technology. Since we launched the TRD/TRD2 decoding amp integrated machine, has been well received by fans love, this is no exception, we launched the digital decoding scheme for TRD3 update. Let us learn TRD3.
TRD3 adopts the whole aluminum alloy body, fine sand blasting surface treatment process, shape elegant chic, delicate touch.
The TRD3 operation is simple and convenient, the design of a key touch type full function.
Rich interfaces (USB/Android, optical fiber, coaxial input), meet enthusiasts all mainstream digital audio access.
High quality power adapter, powerful output DC9V 1.3A, power of 12W, coupled with the patent power processing module inside the machine, providing excellent power supply of TRD3, the adapter can be changed using line design, the mainstream of certification, universal.

From the above test results show, the indexes of TRD3 are very good. TCG TRD3 a few odd harmonic components, only the two harmonic, this figure is very similar with the tube amplifier. Such a FFT, can reflect the machine voice is warm, bottom noise all below -115dB, -60dBFS graph reflects the dynamic range of the machine, the curve is very clean and background noise very bottom, the dynamic range of the machine is very good, also is the reduction ability of small signal is quite good, rich details. The dynamic range is one of the most important indexes of DAC.
The decoding part of quality is very high, the amp section moisture resistant to enjoy high-quality music, become the TRD3 standard.
