DPA-3655QR

DPA-3655QR

It is a 3 input x 6 output Speaker Processor. The 3 input levels are displayed by rows of 6 level leds + 1 clip led.The 6 output levels are displayed by rows of 5 level leds + 1 clip led + 1 Limiter led. The unit has 3 analog inputs,a stereo digital input, and 6 analog outputs. Each input has 5 parametric filters which can be selected as Bell filters or Shelving.

Each output has 5 parametric filters which can be selected as Bell or Shelving, a Hp and a Lp filters up to 24dB/Oct.

Output Limiters are Working on the signal RMS value. Linking functions between inputs and linking functions between outputs are available. A function is allowing to have ramps closing the output level on parameter changes, when the unit is used as installation unit, this function can be excluded when the unit is used live
and it is necessary to perform small changes to the set parameter...on the fly. The Pc SW for the remote control is allowing to connect in net more units.
