Operating Manual - nX, nXe, and nXp 150W/75W Power Amplifiers
9.2c Power On Delay
-
Use this feature (nXe and nXp only) to delay the amplifier turning on when first powered up or when
waking from sleep. Delay is measured in increments of 100mS, with the limit at 25.5 seconds. The power amplifier should be the
last device to power up after other system components have turned on and stabilized. Multiple amplifiers 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 models, the sleep clock timer can be set from 0 to 120 minutes
9.2f Factory Installed Options
(not shown)
- Factory installed options currently include AES3, CobraNet, or Dante. Options
are auto-detected on live amplifiers, but can be added to virtual amplifiers 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 filters, 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 channel.
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-defined setups to be named, saved to, and recalled from the amplifier or a
networked computer. Several other utility functions are available as well. Presets are a snapshot of all current settings on a given amplifier.
nX amplifiers 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 amplifier using <Save Preset To "nX***">, or saved to the
PC using <Save PresetTo Disk>. Individual preset files use the extension (*.pne).
9.3a Sub Presets
:
Instead of saving or recalling an entire preset affecting all device func
-
tions, a sub-preset affecting only a user defined sub-set of DSP functions can be created.
Sub-presets load faster. To create a sub-preset, first 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 amplifier by one of the following methods:
1) Use Protea
ne
software on a PC connected to the network to recall files saved on either
the PC or on the amplifier.
2) Use contact closures to load presets 1-4 from memory by wiring switches to the rear
panel contact closure connector.
3) Use an Ashly WR-5 or neWR-5 remote control.
4) Use the event scheduler.
Note: A full preset recall event will overwrite any unsaved changes, so be sure the current
configuration is saved before continuing or any changes will be lost. The amplifier always
loads the last working settings on power-up, to preserve any changes should the power be
inadvertently turned off prior to saving a preset.
Caution: A new preset may have dramati
-
cally different settings capable of damaging sound system components, so be careful not to recall the wrong preset while the
system is on.
