Crest Audio Inc. NexSys v. 3.0

7. Groups

NexSys groups are designed to facilitate the control of ampliﬁers and other devices. Devices

that make sense to control and monitor together can be organized by moving them to the

same group.

For example, if we have a two-way stereo system with two ampliﬁers (left HF, left LF, right

HF, right LF), we might want to make groups of Left & Right High Frequency plus Left &

Right Low Frequency. That way we can control the ampliﬁer channels together in these log-

ical groups. Other examples of what might be a logical group are Concourse Level, Zone 1,

Delay Speakers, etc.

7.1 Creating a group

A group is created by selecting G

roup | New from the menu. You are then prompted to

name the group as shown here. Valid characters for group names include all alphanumerics,

spaces, and keyboard symbols.

There is no limit to the number of groups you

can create. However, there is a practical limit

beyond which adding groups adds complexity

without increasing functionality. It may con-

fuse an operator to control a single device

from many different points within the soft-

ware. [Try starting with a lean plan and gain

some operating experience before creating

numerous groups.]

It is also possible for a device to be in more than one group. Remember, groups are for

access and control convenience and not only physical location.

7.2 Renaming a Group

You can rename a group as simply as you created it. First make sure that the group window

is active (i.e. its border is highlighted.) Then, select Group | Setup from the menu. You will

be prompted to change the name of the group. Press OK to make the change or Cancel to

discard it.

7.3 Deleting a Group

Make sure the group window you want to delete is the active window (by selecting it).

Select Group | Delete Group from the menu. A warning will appear to verify that you real-

ly want to delete the group.

7.4 Adding Devices to the Group

Most often, you will add devices to your group that already appear in the Plan Inventory.

Adding devices in this case is simply a matter of dragging them from the inventory and

dropping them into the group. Devices can be moved or copied from one group to another.

Note that devices can only be copied from the Plan Inventory, they cannot be moved from

it.
