BRIEF INTRODUCTION

PRODUCT OVERVIEW
This is a high-performance digital DSP processor, supporting multiple analog signal routing, users can connect the machine through USS or Intranet IP and other ways to control the upper computer, simple and friendly PC
software interface is more intuitive, easy to understand the way presented to the user operation.
The CPU uses the ADSP-21571 digital audio processing chip from ADI Corporation of the United States. a dualcore SHARC+DSP processor based on Arm Cortex-AS high-performance floating-point core architecture and supports 64-bit floating-point optimization FIR and IIR algorithms. The A/D part uses AK5552 analog-to-digital conversion chip, which supports a 32-bit 768Khz sampling rate and differential filter circuit input design, effectively ensuring the high resolution and noise filtering of the input signal, and has a professional-grade llBdB signal-to-noise ratio, which effectively inhibits the background noise of the digital audio processing circuit.

PRODUCT WIRING DIAGRAM EXAMPLE

$diyAudio-LA408-Professional -4-input8-output-Processor-Supports- $8$$
Use the USB-B cable to connect to the USB interface of the front panel of the product, and insert the other end into the USB interface of the computer for communication. The computer can run the installed DSP upper computer software to connect and debug the machine

PRODUCT PC CONNECTION DEBUGGING METHOD $diyAudio-LA408-Professional -4-input8-output-Processor-Supports- $9$$

Connect to the RJ45 port at the bock of the machine through the network coble, and connect the other end to the PC or LAN router. After the machine is started, press the “SETTING” key to enter the network information page to view the current IP address and device ID
Run DSP debugging software, click Settings – Network, enter the corresponding IP address and device ID on the page, and click Settings. Return to the main interface and click the “Connect” button in the upper right corner to complete the connection

In case of failure to connect, it is necessary to check the network cable connection, whether the router works normally, and whether the computer NIC driver is correctly set and installed
