Sleep Clock Timer; Preset Recall; Gain Control - Ashly nX Series Operating Manual

Operating Manual - nX, nXe, and nXp 150W/75W Power Amplifiers

10.4 Sleep Clock Timer

On all amplifier models, the sleep clock timer can be enabled or disabled using the front panel factory reset switch as described in
section 4.3. On nXe and nXp series models only, the sleep clock timer can be adjusted from zero (off) to 120 minutes. If sleep mode
is enabled, and there is no audio activity for the duration of the sleep clock timer (fixed at 30 minutes for nX series), the amplifier
goes to sleep until signal is present again or until the power switch is pressed.
Note: The amplifier can not be directly put to sleep or awakened from sleep using software or the event scheduler.

10.5 Preset Recall

Preset File:
A preset file is created when the user saves all current software control settings for this amplifier, essentially tak-
ing a snapshot of the entire amplifier configuration. nXe and nXp amplifiers can store up to 31 user-named presets. Individual
preset files stored on a PC use the extension (*.pne). A preset is saved to the amplifier by using <Preset Options/Save Preset To
(device name)>, or saved to a PC using <Preset Options/Save To Disk>.
Sub Preset File:
A sub preset file consists only of individually selected DSP parameters, and as such requires less load time
when it is recalled. Each DSP function has a check box that assigns it to a sub preset, then the sub preset is saved using <Preset
Options/Save Sub Preset to (device or disk)>. Sub preset filenames also use the *.pne extension, so for best results it's a good
idea to rename the file to indicate that it is a sub preset and not a full preset.
Presets and sub presets can be recalled to the nXe or nXp amplifier using the following methods:
ne
1) Protea Software - Using Protea
Recall (Sub) Preset from (device)>.
2) Contact Closure - There are four back panel contact closure pins labeled "Preset 1-4". When any one of those pins is con-
nected to the preset ground pin, the amplifier loads the preset or sub preset 1-4 as stored in amplifier memory.
3) WR-5 - A WR-5 appears in software as a captive device to its host amplifier. The six buttons on the WR-5 can be programmed
to recall a specific preset or scroll through a defined list of presets.
4) neWR-5 - A neWR-5 will appear in the software menu tree as a device on the network, and must be assigned to the nXe or
nXp amplifier under control. Like the WR-5, the six buttons on the neWR-5 can be programmed to recall a specific amplifier
preset, or scroll through a defined list of presets.
5) Event Scheduler - Protea
With the event scheduler, the installer can assign one or more times of day or days of the week for the amplifier to automati-
cally load a new preset.
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.

10.6 Gain Control

1) WR-1 DC Level Control - The WR-1 remote DC level control potentiometer functions as if it were a front panel attenuator
but in a remote location. Attenuation from a remote DC level control attenuator is cumulative with all other attenuation for a
given channel, including the front panel level control.
1) WR-1.5 DC Level Control - The WR-1.5 offers a four position rotary switch for preset recall and a single DC level control
potentiometer. The gain control functions the same as in the WR-1.
2) WR-5 - The WR-5 buttons can be programmed to select single or multiple input or output channels for remote gain control
function. After programming one of the six buttons for gain control, then pressing that button, pressing the WR-5 up/down but-
tons will adjust the gain for all selected channels associated with that button. A gain range can also be set in software for each
gain button, with a top and bottom limit assigned per button. Note: To use this feature, a (ne)WR-5 remote gain tool must first
be placed in one of the DSP processing blocks of the channels(s) to be controlled. Refer to
ne
software, click <Preset Options/Recall (Sub) Preset from Disk>, or <Preset Options/
ne
software offers an event scheduler for several key amplifier functions including preset recall.
