RKB DX26:2-in 6-out processor 

• Each input has 5 parametric filters and each output has 7 parametric filters. Both input and output filters can be selected to be Bell or Shelving filters. On the outputs a Hp and a Lp filters up to 24dB/Oct. Output Limiter is working on the RMS value of the limiter's input. The Limiter's THR can range up to -30dBu. Each input and output channels have delays up to 850ms, with steps of 22usec.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 up to 32 units.
