Operating Manual - nX, nXe, and nXp Power Ampliers
9.2c Power On Delay -
Use this feature to delay the amplier turning on when rst powered up or when waking from
sleep. Delay is measured in increments of 100mS, with the limit at 25.5 seconds. The power amplier should be the last device to
power up after other system components have turned on and stabilized. Multiple ampliers on the same circuit breaker should have
staggered Power-On Delays to avoid excessive in-rush current which can trip the breaker.
9.2d Idle Time Before Sleep - On nXe and nXp series ampliers, the sleep clock timer can be set from 0 to 120 minutes
9.2e Fault Pin Conguration - On nXe and nXp models,
four logic output Euroblock pins can be assigned to respond to
overtemperature, rail voltage fault, and average power fault condi-
tions as shown to the right. See section 6.4 for application details.
9.2f Factory Installed Options (not shown) - Factory
installed options currently include AES3, CobraNet, or Dante.
Options are auto-detected on live ampliers, but can be added to
virtual ampliers when working in Design Mode.
9.2g Clear All Stored Presets - nXe and nXp only.
9.2h
Sample Rate and Master Clock Source Selection:
Changes to both of these settings can be made by clicking the <Show Advanced Control> box in this menu item. Sample rate can
be set to either 48kHz or 96kHz. Note that at 96kHz, the DSP usage doubles, resulting in half the available processing power for
lters, delay, limiting, etc. Also note that the Feedback Suppressor cannot be used at 96kHz sample rate. Factory default settings
are Auto Selection for clock source and 48kHz sample rate.
9.2i DVCA Control - This feature is used in conjunction with the DSP tab gain tool called <Gain w/VCA>. Use this
feature to create up to four gain subgroups as you would on a mixing console. Any input or output channel can be added to one
or more VCA subgroups for group gain control. While no external hardware control is allowed for this subgroup, a level fader
control object can be added to the project canvas and linked to this named VCA level control.
9.2j DSP Enable/Disable - This removes from operation the input, output, or matrix mixer DSP functions on any chan-
nel. When removed, audio is passed directly through the stage that has been disabled.
9.3 nX Preset Options Menu
The Preset Options menu in the main device window allows user-dened setups to be named,
saved to, and recalled from the amplier or a networked computer. Several other utility functions are
available as well. Presets are a snapshot of all current settings on a given amplier.
nX ampliers can store up to 31 internal presets, each preset storing control data for all
channels and audio functions. Preset names must be 20 characters or less. Changes to an individual
preset can be saved to the amplier using <Save Preset To "nX***">, or saved to the PC using
<Save PresetTo Disk>. Individual preset les use the extension (*.pne).
9.3a Sub Presets: Instead of saving or recalling an entire preset affecting all device
functions, a sub-preset affecting only a user dened sub-set of DSP functions can be created.
To create a sub-preset, rst check the box labeled <Selected for Sub-Presets> in all DSP
control blocks to be associated with this sub preset, then under the preset options menu click
<Save Sub Preset to Disk> or <Save Sub Preset to
"nX***"
>.
A preset or sub preset can be loaded to the amplier by one of the following methods:
1) Use Protea
ne
software on a PC connected to the network to recall les saved on
either the PC or on the amplier.
2) Use contact closures to load presets 1-4 from memory by wiring switches to the rear panel contact closure connector.
