PS-48

PS-48 uses advanced DSP technology, from 24 bit, 48kHz delta-sigma A/D converter and 128 times oversampling. Digital processing includes: gain, polarity conversion, parametric equalizer shelving filter, time delay, frequency division function, compression, limitation and signal routing, all processing is through a pair of 120MHz high-performance DSP processors. The D/A converter uses a 24-bit delta-sigma converter and 128 times oversampling. All inputs and outputs use balanced XLR interfaces to prevent radio frequency interference. You can adjust the gain, delay, or 6-segment equalization of each input channel (each segment can be selected as parametric or high/low shelving). Before setting the crossover point, the signal can be routed inside the DSP. The signals of two or more input channels can be mixed and then routed to the output channel. In the output channel, 4-band equalization can be used (each section can be selected as a parameter) Type or high/low shelving), delay, gain, inverting or compressor module, with such powerful DSP processing function, but only 1U height, and all audio interfaces use standard XLR interface . XTB480 can store up to 30 presets. The preset file adopts a "snapshot" method to completely store all the control data of all current channels. XTB480 is a powerful and easy-to-operate processor. Whether it is for live performances or for fixed installations, it provides precise audio processing capabilities and excellent sound.
