New Arrival FIR sampling rate switchable Audio Processor!

Update time : 2024-04-02 18:32:52

4X8 LA448 adopts ADI's(Analog Devices) latest fourth generation SHARC processor ADSP 21489, with many conventional audio algorithms such as ①routing / ②gain / ③delay / ④compression / ⑤amplitude limiting / ⑥mute / ⑦equalization / ⑧high-low pass filter / ⑨all pass filter and phase. In addition, the following personalized functions are added, and each function is completely closed or opened independently.

The ADSP-21489 processors are available with unique audiocentric peripherals, such as the digital applications interface, serial ports, precision clock generators, S/PDIF transceiver, asynchronous sample rate converters, input data port.

①Signal input distribution routing (ROUNT): The function is to let this output channel choose which input channel to accept the signal. Generally, you can choose A (1) input, B (2) input or mixed input (A+B or mix mono), if you select A, then the signal of this channel comes from input A, and the signal of input B is not accepted. If you select A+B, then no matter which channel A or B has a signal, this channel will have a signal.

LA448 4 IN 8 OUT PROCESSOR FEATURE

A. 96KHz / 192Khz sampling rate switching, with both functions, brings more application scenarios.(Highlights of this processor）

B. Dynamic equalizer is automatically optimized for large signal or small signal.

C. FIR filter can perfectly correct the phase distortion caused by system parameter adjustment.

D. The delay of each channel is up to 1200ms, and the precision is optimized to 0.01ms with the fine adjustment of sound field or phase.

E. 4-way input and 8-way output, complete routing assignment, can be set to multiple working modes.

F. Color LCD display, real-time dynamic level display, Chinese and English interface optional.

G. One key mute and global total volume control.

H. Equipped with WiFi / RS485 central control and drive free USB control interface, which can be adjusted by the control software at the PC.
