Overview
The DX48 is a newly designed digital audio processor from sica. Its extremely low noise floor, high dynamic range, and powerful internal DSP cover the vast majority of usage scenarios. Whether it's a conference room, theater, government project, high-end club, large-scale mobile performance, cinema, or broadcast television, you can use the DX series processors. Advanced circuit design and unique DSP algorithms are at the core of pure, high-quality sound.
 
Application Scenarios
Sica's advanced system audio processor is a high-performance and easy-to-use audio system signal processor. With 4 inputs and 8 outputs, it utilizes the latest analog-to-digital conversion and DSP technology to provide superior audio processing capabilities that surpass competitors.
 
Technical Features
Core Processing:
The DX48's signal processing section uses powerful DSPs and AD/DA converters, operating at a 96kHz sampling rate. This comprehensive processing provides a complete speaker crossover solution.
From input gain/delay/noise gate/EQ/compression/FIR to output gain/delay/polarity/crossover/FIR/EQ/compression/limiter, the parametric equalizer (PEQ) offers up to 16 filter types to choose from.
Filters:
Output crossover filters include the classic Linkwitz-Riley/Bessel/Butterworth, as well as NXF horn filters and FIR filters with slopes up to 120dB per octave.
The newly added MIR linear phase crossover filter makes it easier to combine phases at the crossover point and produces lower latency.
Other Features:
New DSP plugins offer 96kHz FIR filters and more.
The newly designed Hard Limiter allows for constant-rate limiting of signals exceeding the threshold at any threshold, better protecting speaker drivers.
Each input and output channel provides a maximum of 1024 taps for FIR filters. You can use third-party software to create your desired FIR convolution for speaker presets, improving phase response and controlling directivity as needed.
The new MIR linear phase crossover filter has the filter shapes of traditional IIR filters (Linkwitz-Riley 24+48/oct), but does not produce any phase shift. The latency produced is approximately 50% of the FIR filter.
