AP48 PROFESSIONAL DIGTAL SIGNAL PROCESSOR

Application:

Description:

AP48 : 4 in 8 out system The AP series digital speaker processor adopts the fourth-generation SHARC ADSP-21489 high-performance floating-point DSP chip, and adopts the dual-core architecture design of ARM system management and DSP signal processing. The stability of the system is extremely high, which avoids the sound from being affected by the system during the use process and other factors causing the sound to be intermittent and silent, etc.; It also uses imported ELNA capacitors and selected audio-specific devices to ensure that the processor's impact on acoustic dyeing is minimized. Built-in pink/white noise/sinusoidal generator; Ethernet+USB+RS232/485 control interface, opened TCP/IP and serial port protocol to achieve third-party control; flexible GPIO ports (two inputs and outputs each) facilitate system integrated control [ Optional GPIO expansion box]; Free and convenient group debugging function, input and output channels can be selected according to numbers or symbols, grouping and joint debugging, support 23 groups of scene presets, can be flexibly transferred, With back-end password setting function to ensure the confidentiality of user's frequency response data, with Chinese and English operation interface makes operation and debugging extremely simple and convenient.
