9.4d DSP Control Tab
All signal processing is done in the DSP control tab, with separate input and output sections and a cross-linking matrix mixer
between. From left to right, each channel in the DSP tab includes the following features:
Input/Output Channel Number
- Click on this to use each channel's clear, copy/paste, link, and sub preset functions.
Input/Output Channel Name
- The user can name each input or output channel.
Input/Output Mute Button
-
Mutes the input or output. Note that only the
output mute button
lights the front panel mute LED
.
Input/Output LED
- Shows signal present or clipping for that DSP input or output channel.
Pluggable DSP Blocks
-
Six pluggable DSP blocks are available for each input and output. To use, right-click on an empty DSP
block to select one DSP function from the drop-down list. Left-click on the placed DSP function to adjust its parameters, or right-click
on it to bypass, select for sub-preset, copy/paste to another similar block, or delete. Total DSP usage is indicated as a percentage at
the bottom of each input section in the DSP tab. Increasing the number and complexity of applied DSP tools increases the DSP usage.
Total DSP usage cannot exceed 100%. All DSP functions are listed below, with details on the following pages.
1) Dynamics controls
- Clip limiter (infinite ratio), compressor, autoleveler, ducker, and noise gate. Ambient noise compen
-
sation is available on outputs only.
2) Gain
functions
- Gain, gain with VCA, RD-8C remote control gain, neWR-5 remote control gain
3) Equalization
-
31 band graphic EQ, 10/6/4/2-band parametric EQ, feedback suppressor (input), FIR filter (output)
4) Crossover
functions
- Four-way, three-way, and two-way crossovers are available on outputs only. HPF and LPF filters
are available on both inputs and outputs.
5) Speaker Delay/Delay
- At 48kHz sample rate, maximum speaker delay is 21mS and maximum delay is 682mS. At 96kHz
sample rate, maximum speaker delay is 10mS and maximum delay is 41ms.
6) Metering
- -60dBu to +20dBu display
7) Signal Generator
- Pink noise, white noise, sine wave
