Revision 3 18
An example of parametric equalizer 1 (EQ 2: PEQ 1) is shown. Here four different
parameters can be edited:
•
Bypass . On – the equalizer band is bypassed. Off – the equalizer band is
active,
•
Gain . Allows to change the boost/cut of the frequency band by +/- 10 dB,
•
Frequency . Allows to change the center or edge frequency (for High-shelf and
Low-shelf) of the band,
•
Q . The opposite of the bandwidth. Higher Q values mean narrower bandwidth
(for parametric equalizers only).
6.3.3.6. Delay
The Delay section allows user to apply signal delay for the corresponding channel.
Three different states of delay configuration are available:
•
Bypassed (If the channel delay is bypassed only system latency is shown)
•
Single (Minimum delay of 1 sample)
•
Double (Minimum delay of 2 samples)
For more information about delay settings please refer to section 6.3.5 Delay Settings .
Figure 18. Channel Delay Menu.
In chosen channels Delay menu user can see and adjust the delay of the channel in 3
different ways:
•
Samples . (1-700 in Single mode and 2-1400 in Double)
•
Time . Delay in milliseconds (ref. to 48 kHz)
•
Distance . Delay in meters (ref. to c=344 m/s)
Channel delay menu shows total introduced latency of the system including delay,
system latency & look-ahead limiter. IA 202D / IA 402D amplifiers have fixed minimum latency
of 52 samples (1.07 ms). Depending on the loaded preset look-ahead limiter latency is added
to the channel delay (up to 2 ms, 96 samples). This allows the user to know the total system
latency at any time.
6.3.3.7. Reset User Params
The Reset User Params menu allows to reset all current channel user DSP settings such
as:
•
HP Filter
•
Equalizers
•
Delay
•
Input Gain
•
Phase Inversion
