NexSys v. 3.0 Crest Audio Inc.
Groups
A group is a collection of devices placed together for the purpose of common control or
monitoring. You can create a group by selecting Group | New from the menu. Any device
that can be controlled by NexSys can be added to a group. A single device may be added to
more than one group.
Groups exist to customize a Plan according to your specific needs. They serve as a tool to
logically organize your Plan. For example, you may create a group that contains all ampli-
fier channels for the low frequency drivers. You may also have a group for the stage left.
There is no practical limit to the number of groups you can create.
All of the amplifiers within a group may be controlled by the group control panel. Different
group views provide console-like control arrangements for the channels in a group.
Snapshots - Plan & Group
Snapshots are a way to save NexSys control settings for later recall. A device’s current set-
ting, such as gain, is “snapshotted” and saved under a user-defined name for instant recall
at a later time. Snapshots cover two levels, Plan and group. You can open the snapshot win-
dows by selecting P
lan | Snapshot | Open or Group | Snapshot | Open.
Scenes
A scene is a way of saving/recalling different desktops (arrangements of windows) within
NexSys. One scene may contain the amplifier control windows for the lower level of a sta-
dium while the controls for the upper level could be saved in a different scene. Another may
just contain the snapshot window as a means for simply controlling a complex sound sys-
tem. Scenes can be saved via the scene maintenance window. This window is accessed by
the Scene button on the tool bar or from the DeskTop | Scene menu.
Event Monitor
The Event Monitor tracks system wide faults and activity and generates the Event Log. An
Event Log shows the “what and when” of events which occur while NexSys is running. The
Event Monitor can be viewed by selecting Options | Event Monitor. The Event Log can
also be saved to a file on the host computers hard disk. Once the Event Log is activated, all
critical system operation information, including date and time of the event is recorded to a
text file. You may give the Event Log a unique name to keep its data separate from other
logs.
Software Security
The security features of the NexSys program allow three levels of security access with vary-
ing privileges for each level. This feature allows the system administrator to tailor who will
have access to various control functions within the software. The Security Administrator
window can be opened by selecting Options | Security from the menu.
Event Scheduler
The Event Scheduler is a second software application supplied as a companion program to
NexSys. Event Scheduler allows almost limitless automated control of all NexSys func-
tions. You can open or switch to the Event Scheduler by selecting Plan | Event Scheduler
from the menu. When NexSys and the Event Scheduler appear as the top two items in the
task list, you can switch between these two programs by pressing ALT + TAB.
