DLP-240: is a 2 into 4 out of the speakers processor. Two input level consists of 6 level light +1 lamps are arranged to form cutting. 4 output light is composed of 5 level light +1 cut lamp +1 limiting lamp arrangement. The machine has 2 analog inputs, 1 vertical acoustic digital input and 4 output. Each input has 5 parameters of filter, each output has 7 segments of filter parameters. The input and output filter can be selected for Bessel or Chebyshev filter. High output and low pass filter at 24dB/Oct. Output limiting pressure limit is RMS. Limiting THR range up to -30dBu. 22Us step, each input and output channels with up to 850ms of delay. Have the function of linking between the input and output. When the machine is installed the machine when change the parameters, this function allows ramps to close the output level. When the need for on-site demonstration and parameters need small change, can cancel the function to set the operation. To the remote control PC software allows simultaneous connection of 32 machines.
