A switchable configuration may be useful in a meeting room with a movable divider, partition, wall or door. In this case, the unit may be switched to Dual HDL300 system operation when the meeting area is configured to the larger size, and single system operation when it is divided into two smaller rooms.
A 2-way A/B manual ethernet switch is needed in the configuration to switch in and out the one integrated microphone and speaker bar. The switch needs to support a minimum of 10/100 Base-T Ethernet standards and pass PoE power.
The first set-up diagramed below switches one of the integrated microphone and speaker bars in and out of the system. This allows for a dual operation when the second microphone and speaker bar is switched into the system and allows for one of the smaller partitioned rooms to operate in single HDL300 mode when the rooms are divided.
The second set-up illustrated below switches one of the integrated microphone and speaker bars between two systems. When the “B” position is selected on the switch both configurations will work together as a dual system. When the “A” position is selected, the left microphone and speaker bar will connect to the left connect module and computer, and the right microphone and speaker bar is connected to the right connect module and computer. These two separate systems can each run independently in the two divided rooms.
Downgrading a Dual HDL300 system to Single HDL300 system
If you choose to downgrade your Dual HDL300 system to a single system and no longer use ethernet switching, you can easily reconfigure your dual system to accommodate changes in your space as follows.
