4. PCB board size is very small, 22 * 16cm, the proportion of very nice coordination, export terminals in the same layout all surfaces, easy to design their own chassis installation.
Good decoder, power must be designed to focus, so we have adopted a multi-channel power supply, 9018 cores, digital, analog, I / V converter / LPF, control parts, display and other features has a separate power supply chip power, reducing interference between the various functional blocks, and strive to achieve the best sound. PCB strict accordance with the digital, analog, is divided into blocks and single-point ground handling.
Regulator chip uses a Linear? Sprinter ultra low noise regulator LT1763. The regulator has a noise output in low 20uVrms 10Hz ~ 100KHz frequency band, the output current up to 500mA, performance is extremely good. Board also designed another alternative to the regulator, the figure that is empty position, where you can use National Semiconductor NS's LP38798 to replace LT1763. LP38798 is a performance extremely perverted regulator, under 10Hz ~ 100KHz bandwidth, output noise as low as 5uVrms. Output current up to 800mA, and the compression ratio of the output ripple under 10KHz PSRR is 90dB. (Usually at 1KHz if PSRR 70dB already reached a high ripple rejection ratio regulator of) 100KHz when 60dB.
5 Analog output section, a single operational amplifier design, you can use the op amp seat, to facilitate replacement of the op amp.

Board input and output terminals range, covering most of the current interface various common audio equipment.
There are six kinds of input terminals 7 Specifications: Coaxial, BNC, fiber, AES / EBU, USB, I2S, this six signal input can be selected through the screen with the rotary switch. (Signals can all access, you need to use which one to choose which channel on the display, and with a memory function, power is automatically restored once the memory configuration).
Coaxial, fiber optic, BNC, AES / EBU all perfect support 44K, 88.2K, 96K, 176.4K, 192K sampling rate, and can accurately display on the screen.
USB supports DSD64, DSD128, DSD256, DSD512, PCM supports up to 384K.
There are two output terminals of the specification: XLR fully balanced output (real balance) (5Vrms), RCA unbalanced outputs (2Vrms).
Power board using double-sided 20z (76um) thick copper design, thickness 2mm, 5-way power, LM317, LM337 regulator. Adaptation motherboard power supply needs. Power board size is 9cm * 20cm, installed and fully consider the size of the problem with the motherboard, ensuring 430 chassis can accommodate. Power moderators filter capacitor for Nover 5600uF / 40V, you can own with the likes Shaoyou capacitor, the capacitor can hold a maximum diameter of reserved space for a variety of two feet capacitance (such as larger diameter nichicon super through Series) 35mm or less
P.S.: Many users are concerned with question question on many parameters. This kit does not use professional AP tester to test. Asus computer only XONAR D2 PCI sound card is probably the RMAA tests done (fairly and 1212M), because limited back recorded sound card circuit tester can not be compared with the AP, but RMAA back recorded test parameters can basically reflect this kit level of.
