The unit provides 1 channel with an output power of up to 500W at 4Ω. In addition, it also offers a full set of DSP front-end signal processing, which allows you to adjust the EQ parameters of the speaker via PC software. To ensure maximum stability, the JY-500SUB is also equipped with an efficient universal switching power supply with a peak power of up to 1000W. The power amplifier output channel uses IR's Class D power amplifier driver chip. The JY-500SUB includes a full set of complex processor functions for loudspeakers, driven by a powerful 28\/56-bit Sigma DSP processor with a sampling frequency of up to 192kHz, and is also equipped with high-performance 24-bit AD\/DA converters.\u003cbr\u003e\u003cbr\u003eJY-500SUB can process functions such as noise gate, crossover filters, input\/output parametric equalization, RMS limiting, calibrated delay, and all-pass filters to maximize the performance of active loudspeakers. In addition, the clipping\/limiting function per channel allows the output to decay slowly when reaching the clipping threshold to protect the speaker. The built-in efficient heat dissipation system and over-temperature protection ensure maximum stability of the unit.\u003cbr\u003e\u003cbr\u003eDSP-related parameters such as gain, crossover, and phase can all be set and controlled via the front panel knobs.\u003cbr\u003e\u003cbr\u003e\u003cb\u003eFeatures:\u003c\/b\u003e\u003cbr\u003eExcellent Performance\u003cbr\u003e* High Output Power: 1x500W at 4Ω, THD=1%\u003cbr\u003e* Efficient switching power supply with main power supply +\/-75V.\u003cbr\u003e* Class D power amplifier driver chip from IR, achieving low distortion and high efficiency.\u003cbr\u003e* Full set of circuit protection functions: over-current, over-\/under-voltage, output DC, and over-temperature protection.\u003cbr\u003e* Excellent sound quality performance, 28\/56-bit high-end converters with a maximum sampling frequency of 192kHz.\u003cbr\u003e\u003cbr\u003eHigh-end DSP Engine\u003cbr\u003e* LINE IN and LFE input channels feature 20-band parametric equalization filters.\u003cbr\u003e* Filters can be selected as Bessel, high\/low Shelving filters with variable Q values.\u003cbr\u003e* Crossover filter slopes range from 6dB\/Oct~48dB\/Oct, including Butterworth, Bessel, and Linkwitz-Riley types.\u003cbr\u003e* Each input channel has a precision dynamic range controller, consisting of ratio, threshold, and optional RMS limiting.\u003cbr\u003e* The input channel is equipped with a noise gate function for extremely low static noise, as well as a high-pass filter with a slope range of 6dB\/Oct~48dB\/Oct, selectable from Butterworth, Bessel, and Linkwitz-Riley types.\u003cbr\u003e\u003cbr\u003e\u003cb\u003eSpecifications:\u003c\/b\u003e\u003cbr\u003ePower \u0026amp;
