Summary
4-in-8-out DSP processor with multiple conventional audio algorithms such as routing/gain/delay/compression/limiting/mute/equalization/high and low pass filters/all-pass filters and phase.
The audio processor is an important part of the professional stage audio system. They usually use digital signal processing (DSP) technology to process audio signals on stage to ensure audio clarity, balance and quality. Recently, in order to meet more stage performance applications, Sinbosen launched a 4-input and 8-output professional audio processor - LA448.
The LA448 series uses the latest fourth-generation processor and has a variety of conventional audio algorithms such as routing/gain/delay/compression/limiting/mute/equalization/high and low pass filters/all-pass filters and phase. The following personalized functions have been added, and each function can be turned off completely or turned on independently.

Advantages of LA448 processor: 1. 96KHz/192Khz sampling rate switching, both functions, bringing more application scenarios. 2. Dynamic equalizer automatically optimizes for large or small signals. 3. The FIR filter can perfectly correct the phase distortion caused by system parameter adjustment. 4. The delay of each channel is up to 1200ms, and the accuracy is optimized to 0.01ms through fine-tuning of the sound field or phase. 5. 4 inputs, 8 outputs, complete routing distribution, multiple working modes can be set. 6. Color LCD display, real-time dynamic liquid level display, Chinese and English interface optional. 7. One-click mute and global total volume control. 8. Equipped with WiFi/RS485 central control and driver-free USB control interface, which can be adjusted through PC control software. |
