Product parameters:

4.8SP is a 4-segment input / 8-segment output digital signal processor with precise and extensive audio control functions. Function buttons on the front panel interface allow all control parameters to be sent quickly, eliminating hidden submenus. Backlit 2x20 feature LCD displays channel and function Settings. Related buttons provide access to all audio features and system tools. Faster setup and powerful visual input/output routing, EQ, filter curve system, two USB interfaces (one on the front panel and the other on the rear panel) and RS-232 interface can be used to control software and PC connections. A 6-foot USB-A to USB-B cable is available. The advantage of the software is that it includes very powerful preset capabilities and is very intuitive in terms of audio routing and control processing.

The 4.8SP uses advanced DSP technology from A 24-bit, 48kHz delta-Sigma A/D converter with 128x oversampling. Digital processing includes: gain, polarity conversion, parametric equalizer frame filter, time delay, frequency division function, compression, limiting and signal routing, all processed through a pair of 120MHz high-performance DSP processors. The D/A converter uses a 24-bit delta-sigma converter with 128-fold oversampling. All inputs and outputs are using a balanced XLR interface that prevents RF interference.

You can adjust the gain, delay or 6 equalization segments of each input channel (each segment can be selected as parametric or high/low scaffolding), the signal can be routed within the DSP before setting the crossover point, and the signal of two or more input channels can be mixed and routed to the output channel, where the output channel, You can use 4-stage equalization (each stage can be selected as parametric or high/low scaffolding), delay, gain, phase reversal or voltage limiter modules, with such powerful DSP processing capabilities, but only 1U height, and all audio interfaces use standard Canon (XLR) interfaces.

4.8SP can store up to 30 presets. The default file takes a snapshot to store all control data of all current channels.

4.8SP is a powerful, user-friendly processor. Whether in live performance or for fixed installation, it provides precise audio processing power and superior sound.
