Introduction:
Digital receiver using the company's latest CS 8416 digital receiver chip, support the highest output 192KHZ. DAC decoder chip adopts the best CS4398, the chip is delicate and soft, very high resolution, and the United Kingdom chord MARANTZ Spark CD and CD-end series, and many other brands have adopted chip times, we can see the excellent performance of the CS4398 is not Usually the chip can be compared, in terms of the parameters, CS4398 all parameters are the same price than the WM8740 DAC. Built-in USB receiver and independent 24bit DAC decoding, when connected to a computer using a USB DAC functions as a high-end external sound card. USB input and coaxial input is automatically selected.

parameter:
Size: 86mm * 100mm

Input port:

Input Volatage:  AC15V-0-AC15V  (13-15V is OK)      AC0-9V  (9-15V is OK)
Digital input: COA (coaxial) USB of a group.
Sampling frequency: 32K -192K / 24BIT (Which supports only USB inputs 16bit / 44.1K and 48K)

Power LED:

Signal lock indicator (locked) LED
COAX coaxial input channel is selected directions
USB USB output channels is selected directions

Core chip:

Digital Receiver: CS8416IC up to 192K / 24BIT SPI & I2S output. USB support 16BIT / 48K signal.
Digital receiver: CM102 This machine uses SPDIF output signal
D / A converter (decoder chip): CS4398 120dB dynamic range supports 24bit / 192K sampling

 

Test pattern:
Test environment: coaxial input
Test Equipment: AP SYS 2
AP 2 Series Audio Test Equipment:

Main feature;
• Unmatched performance, recognized standard audio test
• dedicated analog circuitry can detect minimal residual noise and total harmonic distortion plus noise (THD + N)

Typical residual THD Audio Precision2 products + N at 2.0 Vrms or less 115 dB. Even the conservative Audio Precision provisions of its total harmonic distortion plus noise (THD + N) of -112 dB, 2700 Series products are still worthy of a high-performance leader in the industry, he said undisputed.

High analog performance;
Audio Precision high-performance analog circuits, there is no sibling any digital converters can exceed it. 2700 series low noise floor, not any other sibling analyzer (even with analog components) can be compared.

AP 2 using the actual test USB DAC 48K and 96K coaxial signal inputs.
THD + N <0.001%, 20HZ-20KHZ
THD + N <0.0006% 2 0HZ-6K HZ

Note: This is a Kit, All parts need you to weld and test it. "SMD IC" have weld on the PCB. You just need weld other parts.
