Operating Manual - nX, nXe, and nXp Power Amplifiers

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 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 it's 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

 - Brick Wall Limiter, Compressor, Autoleveler, Ducker, and Noise Gate. Ambient Noise Compensation 

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) Delay

 - At 48kHz, Maximum Speaker Delay is 21mS, and maximum Delay is 682mS. At 96kHz, they are 10mS and 341ms 

respectively.

6) Metering

 - -60dBu to +20dBu display

7) Signal Generator

 - Pink noise, White Noise, Sine Wave
