Yes, two standalone HDL300 systems can be combined to make a dual HDL300 system. This configuration is only supported when one of the integrated microphone and speaker bars is a part number 101191 or 101198. A firmware upgrade is also required. See below table for more information or contact Nureva^® for support.

It's possible to purchase a second integrated microphone and speaker bar to upgrade your current HDL300 system to a dual HDL300 system.

The part number is Dual-HDL300-B-U or Dual-HDL300-W-U, which includes an integrated microphone and speaker bar and an Ethernet cable.
