Auto Null Process
Nulling is required to electronically balance an audio device, in this case a Control Unit, with a 2-wire intercom system.
Important!
This procedure MUST NOT be performed while the system is in use in a game environment. This process uses
audible tones that will disrupt communication between users.
1. Ensure that all sideline and press box units are connected via stadium wiring and that wired BeltPacks are
connected to the press box system prior to nulling.
2. Using X-Ware, null each Control Unit, one at a time, at initial system setup.
Note:
You may also null a system from the Control Unit menu without X-Ware. The
Run Auto Null
command
is found under the Wired Settings menu.
X-Ware Auto Null Screens
The Auto Null function is available from the Conferences View in X-Ware. To null a Control Unit, follow the steps below:
1. Select the Auto Null button on the Control Unit you wish to null.
2. Confirm your decision to auto null on the prompt that displays.
3. Once nulling begins, a nulling status screen will display, indicating that null is in process on the Control Unit’s port
indicated in red.
