Paulkitson LA408 Professional DSP Audio Processor 8 Channel 768kHz 32-bit 110dB SNR FIR PEQ GEQ for Studio Live Sound Recording

LA-408 Digital Audio Processor

The LA series digital audio processor is a high-performance digital DSP processor that supports multi-channel analog signal routing. Users can connect to the device via USB or internal network IP for PC control. The simple and user-friendly PC software interface provides users with an intuitive and easy-to-understand operating experience.
Input channels feature 5-band DEQ, 31-band GEQ, and 15-band PEQ, while output channels offer 15-band PEQ and FIR functionality. Each channel has adjustable compressor and noise gate settings. Thirty built-in factory presets are available for one-click setup in most audio systems, and users can also customize, save, and recall their own settings. The PC software includes a signal generator for convenient on-site speaker debugging and calibration.
The CPU uses the ADSP-21571 digital audio processing chip from Analog Devices (ADI), a dual-core SHARC+ DSP processor based on the Arm Cortex-A5 high-performance floating-point core architecture, supporting 64-bit floating-point optimized FIR and IIR algorithms. The A/D section uses the AK5552 analog-to-digital converter chip, supporting a 32-bit 768kHz sampling rate. The differential filtering circuit input design effectively ensures high resolution and noise filtering of the input signal, while also providing a professional-grade 118dB signal-to-noise ratio, effectively suppressing the background noise of the digital audio processing circuit. The DAC decoding section uses the AD1955 chip, providing 24-bit, 192kHz master-grade audio format output with a 120dB high signal-to-noise ratio, meeting the requirements of various mainstream audio sources
