OUTPUT FIR
Each output of the RCM-28 offers a 512 taps FIR filter.
Element Description
Switch for displaying frequency response (magnitude) or phase response (phase)
Switch for scaling the dB-axis to 25 dB (± 12.5 dB) or to 50 dB (± 25 dB)
Displays the resulting transfer function of all filter and level trim settings and therefore graphically
displaying the audible result at the amplifier‘s outputs. The audible result is displayed in bright
colors while all ”electrical” graphs are drawn in dark colors.
The ”Sum” switch causes display of the summed signal of the output channels. If the ”Sum ” switch
is not pressed the output channels’ transfer functions are indicated separately.
Switch for additionally indicating measured speaker transfer functions. For this function to be
effective you first have to load speaker data in the ”Speaker” tab.
Switch for including programmed delays in the frequency or phase response indication. The delays
mainly affect phase response indication. Indicating the sound system processor channels’ summed
signals reveals very clearly the effect that the delays have on the frequency response, e.g. as notch
filter effect.
