Operating Manual - ne8800, ne4800, ne4400 DSP Processor

Preset Options

Presets and Sub Presets

The NE processor will store up to 30 device presets or sub presets . A device preset takes a "snapshot" of the most common

audio settings and stores control data for all channels and all audio functions . A sub preset, although in the same format as the

full preset file, scans for and only stores the DSP parameters individually tagged as sub presets within each DSP tool box, within

one channel or across multiple channels . Sub Presets are thus used to change only the selected functions . When naming presets

or sub presets, indicate in the preset name if it is a sub preset, this will help later when assigning the sub preset to a recall event

such as contact closure or WR-5 control . Individual presets (or sub presets) can be saved to the processor by using <Preset Op-

tions/Save Preset (Sub Preset) To Device>, or saved to a PC using <Preset Options/Save (Sub Preset) To File> . Preset and sub

preset files for Ashly NE products use the extension (*.pne). A sub preset report can be generated to see what specific actions

will be taken when loading a sub preset .

A preset or sub preset file can be recalled from either a computer or from the processor's internal memory. An installa-

tion can be set up so that an Ashly WR-5 active programmable remote, or a contact closure, triggers the recall of presets or sub

presets stored in the NE processor . For contact closure preset recall, use the software Logic I/O tab to assign one of 30 presets

or sub presets to one of the eight digital logic input pins on the processor's back panel . For Ashly WR-5 preset management,

connect the WR-5 to the NE processor and use the WR-5 device in software to assign device and preset (or sub preset) controls .

Caution: A new preset may have dramatically different settings capable of damaging sound system components, so be careful

not to recall the wrong preset while the system is on.

The NE Processor Control Surface

Input Source

The input source tab displays all available inputs to the NE processor per channel pair, and allows the user to select which

input type and in what priority those inputs are to be used . Also shown is the current master clock and sampling rate .

Net Matrix Mode: If a network audio card is installed, and <Net Matrix> is selected under the device options menu, the

network audio input is removed from the primary input source tab and instead placed in the resulting <Net Matrix Inputs> tab,

along with the input DSP controls, allowing analog or AES3 inputs to be routed through the input DSP section and on out to the

external digital audio network . Likewise, the <Net Matrix Outputs> tab allows extraction of network digital audio channels for

routing to the output DSP section and out to the NE processor's analog output channels .

DSP Controls

All of the DSP control is done in the DSP tab . If additional network audio is available to the DSP processor, select the <Net

Matrix> item under the device options menu, and the DSP controls will be split into input and output sections for interfacing

with the external Dante or CobraNet audio network . Complete explanation of each DSP function is available in the software

help. Open a placed DSP tool and press F1 for help with that tool. DSP controls include the following functions:

Dynamics: Brick Wall Limiter, Compressor, AutoLeveler, Ducker, Gate, Ambient Noise Compensation (outputs only)

Gain: Gain, Gain with VCA, Remote Gain, and WR-5 Remote Gain

Equalization: Graphic 31 band, Parametric EQ with 10, 6, 4, or 2 band, Feedback Suppressor (inputs), FIR filter (outputs)

Crossover: HPF and LPF on both inputs and outputs, 4 Way, 3 Way, or 2 Way Crossover on outputs only

Delay: Speaker Delay (0-58mS), Delay (0-1 .365mS)

Tools: Audio Meter (0 to -80dBFS), Signal Generator (pink noise, white noise, sinewave)
