A switchable configuration for an audio conferencing system may be useful in divisible rooms with movable dividers, partitions or walls. This article outlines how to configure an HDL410 system for use with divisible rooms.
When setting up a switchable configuration an Ethernet switch and an extra connect module are added during the system installation. The switch is used to route the audio signal from the microphone and speaker bars to each connect module.
Choosing a switch
When choosing an Ethernet switch the following specifications should be considered.
- Two-way A/B switch
- Minimum of 100 Mbps data rate
- Be able to pass PoE power
- 2 - RJ45 input ports
- 2 - RJ45 output ports
- Network connection
- For switching remotely via telnet, web browser or SNMP
- Latching and non-latching switches are suitable
In most cases, an Ethernet A/B switch that meets these specifications will be suitable for setting up HDL410 systems into switchable configurations. Examples of some switches are below.
Brand of switch
Black Box (North America)
Black Box (Europe)
HDL410 systems should have the latest firmware version installed for an optimum audio conferencing experience.
Room size considerations
Room size is an important consideration when choosing how to configure the systems for a divisible room. The divisible room should meet the size requirements for an HDL310 system when divided into smaller spaces and the size requirements for an HDL410 system when combined into a large space.
- HDL310 - spaces up to 30' x 30' (9.1 x 9.1 m)
- HDL410 - spaces up to 35' x 55' (10.7 x 16.8 m)
HDL410 - Large room divided into two small rooms
Install the HDL410 system according to the installation instructions, with the addition of an Ethernet switch and a second connect module as shown in the diagrams below.
Configuring for two small rooms
Selecting position "A" on the Ethernet switch divides the system into small rooms.
Configuring for a large room
Selecting position "B" on the Ethernet switch combines the system into a large room.
