Operating Manual - nX, nXe, and nXp Power Ampliers
10.4 Sleep Clock Timer
On all amplier models, the sleep clock timer can be enabled or disabled using the front panel factory reset switch as de-
scribed 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 (xed at 30 minutes for nX series),
the amplier goes to sleep until signal is present again or until the power switch is pressed.
Note: The amplier 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 le is created when the user saves all current software control settings for this amplier, essentially
taking a snapshot of the entire amplier conguration. nXe and nXp ampliers can store up to 31 user-named presets. Individual
preset les stored on a PC use the extension (*.pne). A preset is saved to the amplier 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 le 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 lenames also use the *.pne extension, so for best results it's
a good idea to rename the le 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 amplier using the following methods:
1) Protea
ne
Software - Using Protea
ne
software, click <Preset Options/Recall (Sub) Preset from Disk>, or <Preset Op-
tions/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
connected to the preset ground pin, the amplier loads the preset or sub preset 1-4 as stored in amplier memory.
3) WR-5 - A WR-5 appears in software as a captive device to its host amplier. The six buttons on the WR-5 can be
programmed to recall a specic preset or scroll through a dened 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 amplier under control. Like the WR-5, the six buttons on the neWR-5 can be programmed to recall a specic amplier
preset, or scroll through a dened list of presets.
5) Event Scheduler - Protea
ne
software offers an event scheduler for several key amplier functions including preset
recall. With the event scheduler, the installer can assign one or more times of day or days of the week for the amplier to auto-
matically 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 at-
tenuator 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 buttons 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 rst be placed in one of the DSP processing blocks of the channels(s) to be controlled. Refer to section 9.4d.
