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
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
Linear frequency response of the 'pre-linearized'
monitors on stage
the loudspeaker cabinet.
The IRIS-Net ™ module RCM-28 (under development) offers,
™ instead of the AES3 digital input, a CobraNet
making it possible to integrate PowerH power amplifiers into
CobraNet ™ networks.
