Operating Manual - nX, nXe, and nXp Power Ampliers

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 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 (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, essen-

tially taking 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:

1) Protea

Software - Using Protea

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 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

software offers an event scheduler for several key amplifier 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 amplifier to au-

tomatically 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 first be placed in one of the DSP processing blocks of the channels(s) to be controlled. Refer to section 9.4d.
