IRIS-Net
Graphics display Indication
Element Description
Switches between frequency (magnitude) and phase response (phase) indication
Switch for selecting dB-axis scaling of 25 dB (± 12.5 dB) or 50 dB (± 25 dB)
Shows the resulting transfer function of all filter and level trim settings, the visible and audible
result at the amplifier outputs. The audible result is displayed in bright colors while electrical
graphs are indicated in dark colors.
Selecting separate results in a separated display of the two amplifier channels' transfer functions
while sum shows the summed signal of the amplifier channels.
Switch for including programmed delays in the frequency or phase response indication. The
delays mainly affect phase response indication. Indicating the amplifier channels' summed signals
reveals very clearly the effect that the delays have on the frequency response, e.g. as notch filter
effect.
Switch for additionally indicating measured speaker transfer functions. For this function to be
effective you first have to load speaker data in the Speaker register sheet.

Hishelv, and gain.
Hipass, Loshelv / Hishelv creates a low shelving respectively high shelving
Lopass, equalizer with the following edit- able parameters: frequency, slope and
Allpass gain.

adjustable frequency and slope.
Allpass is a filter which only affects the phase but not the frequency
response of the transmission function.
