Introduction to DAC: Digital reception uses CS's latest 8416 digital receiver chip to support the highest 192KHZ output. The DAC decoder chip uses the best CS4398, the chip is delicate and soft, and the resolution is very high. Many CD brands such as British chord and MARANTZ and Spock CD high-end series use sub-chips. It can be seen that the excellent performance of CS4398 is not comparable to the general chip. In terms of parameters, all parameters of CS4398 exceed the WM8740 DAC of the same price. Built-in USB receiver and 24-bit independent DAC decoding, the DAC function is equivalent to a high-end external sound card when connected to a computer using USB. USB input and coaxial input are automatically selected.
You can also use the OTG to USB B-type printer data cable to connect to an Android phone, which is used as a digital signal to analog signal decoder for mobile phones.
Since the digital signal is not distorted, the CS4398 USBDAC can make a normal mobile phone achieve the same sound quality as a traditional desktop CD player.

Introduction to ap 2 series audio test equipment:
main feature
• Unparalleled performance, recognized audio test standards
• Dedicated analog circuitry that detects minimal residual noise and total harmonic distortion plus noise (THD+N)
The typical residual THD+N of the Audio Precision2 family is less than or equal to 115 dB at 2.0 Vrms. Even though Audio Precision has conservatively specified its total harmonic distortion plus noise (THD+N) of –112 dB, the 2700 Series is still the industry's undisputed leader in performance.
Extremely high simulation performance
The Audio Precision analog circuit has high performance and no digital converters of its class can exceed it. The 2700 Series has a low noise floor and is comparable to any other analyzer in its class (even with analog components).
AP 2 Actual Test The USBDAC uses 48K and 96K coaxial signal inputs.
THD+N <0.001%, 20HZ-20KHZ
THD+N<0.0006% 2 0HZ-6K HZ

Installation reference map
The transformer is supplied with AC 12-0-12 and AC12-0-12 output.
When connecting to the DAC, connect as shown below.
Installation note:
Please use an anti-static soldering iron to avoid IC damage.
In addition, the chip has been completely soldered, and the test is OK. Please do not solder the IC pin with a soldering iron.
Installation Tips:
