The exclusive patented power supply module TRD3 plus is adopted, and the non-USB power supply decoder can match the excellent quality. The digital interface combination of CM663 1A upgrade +AKM4390, independent left and right channel filtering and balanced circuit design are adopted. Full-function MCU control is practical and worry-free (with memory). Made of national electronic components, coupled with the excellent circuit design and tuning of TCG team, you will definitely enjoy the ideal high-quality music!
Listening technology company has been developing HIFI sound system, as the name implies, which is listening enjoyment technology. Since we launched the TRD/TRD2/ TRD3 decoding and power amplifier integrated machine, it has been deeply loved by fans, and this time is no exception. Our TRD3 plus has upgraded the digital decoding scheme, and all indicators have been improved accordingly. Let's have a look.
Coupled with TRD3 aluminum alloy body, fine sandblasting process surface treatment, beautiful and elegant, delicate feel. In particular, the newly designed front panel structure technology, acrylic mixed aluminum alloy+,diamond cutting seamless.
TRD3 PLUS, simple and convenient to operate, designed with full function of key touch (with operating instructions).
Rich interfaces (USB/ Android, optical fiber, coaxial input) to meet the access of various mainstream digital audio lovers.
High-quality power adapter, strong output of dc9v to 1.3A, power of 12W. With the patented power processing module of internal machines, TRD3 plus provides excellent power supply. The adapter can be used for circuit design (enthusiasts can upgrade the front power cord by themselves), which is popular and universal.
As can be seen from the above test results, all the indicators of TRD3 are very good. The harmonic of small TCG TRD3 is very strange, with only two harmonics, which is very similar to lark. This FFT can reflect that the sound of the machine is warm, and the noise at the bottom is all below-1 15dB. The graph of -60dBFS reflects the dynamic range of the machine. This curve is very clean, the noise at the bottom is very low, the dynamic range of the machine is quite good, and the reduction of small signals is very good, with rich details. Dynamic range is one of the most important indicators of DAC.
The quality of the decoding part is quite high, and it can be a part of amp. TRD3 PLUS enjoys high-quality music standards.
