LOUDSPEAKER SYSTEM PROCESSOR
DESCRIPTION
●32-bit DSP SHARC process, 96kHz sampling rate, 24-bit AD/DA convert.
● Input processing includes High-cut, Low-cut, 8 PEQ, Noise gate, Gain, Mute, Phase, Delay, Link and so on.
●Output processing includes X-over, 9 PEQ, Gain, Mute, Compressor/ Limiter, Phase, Delay, Link and so on.
●Adjustable PEQ frequency, Gain and bandwidth. We can choose style: Peak, L -shelf, H-shelf, Low cut, High cut, Allpass 1, Allpass 2.
●Every input and output can do matrix assign flexibly, and all the input and output channel name can be changed.
●All the input and output with independent phase curve adjust function, PEQ style choose allpass 1 is 180° curve adjust, allpass 2 is 360° curve adjust.
●The style of all High-cut,Low-cut filter and Distributor unit: Butterworth, Linkwitz-Riley, Bessel; slope is from -6dB/Oct to -48dB/Oct.
●Adjustable compressor/limiter threshold, ratio, attached time and release time.
●Maximal delay time is 680ms for all input/output channels.
●Parameter Settings between any channel can be copied freely, and any channel can be linkage adjusted.
●Displays the current PEQ curves of all input or output channels in any input or output channel window. ●Built-in test signal generator, output mode optional pink noise, white noise and 20Hz-20kHz sinusoidal adjustable, and signal amplitude adjustable.
●The front panel is equipped with input and output levelindicator light, USB control port, rear panel 232 & 485 control port, and Ethernet connection remote control port. One-button connection makes the user's operation easier and faster, and the computer can be wireless
●30 user presets,the complete machine state and each preset can be stored and called separately. The ID setting function can cascade control 255pcs machines, and also has password protection function to make the device more secure.
