FIR Filters
Although FIR filters require a massive amount of processing and are highly com- plex, they are realized in the RCM-26 in addi- tion to the classical filtering and signal pro- cessing functions. Available are linear-phase FIR filters and 'zero latency' FIR filters, which add no further latency to the time signals require to pass through the device.
Users can create their own linear phase 'brick-wall X-overs' and edit them in real time.
Example: Linearization of a floor monitor
Original frequency response of monitors on stage Zero-latency FIR equalization
Potential FEEDBACK frequencies
Linear frequency response of the 'pre-linearized' monitors on stage
For Dynacord loudspeaker cabinets, measurements of the fre- quency and phase response are already provided in the IRIS- Net™. This data can be displayed and merged in IRIS-Net™together with the filter, crossover and delay settings. The superposition then shows the acoustical frequency response of
the loudspeaker cabinet.
The IRIS-Net™module RCM-28 (under development) offers, instead of the AES3 digital input, a CobraNet™ interface, making it possible to integrate PowerH power amplifiers into CobraNet™ networks.
