FreeSpeak - Wireless Intercom

FreeSpeak Edge Base Station supports the FreeSpeak family of wireless intercom, including 1.9 GHz, 2.4 GHz and 5 GHz frequency bands which can be concurrently deployed on an FreeSpeak Edge Base Station system. FreeSpeak antenna transceivers, connected via E1 CAT/Fiber plug and play cable connections or IP using AES67 capable networks, can be modularly added for coverage and capacity of beltpacks which can roam between overlapping transceivers. FreeSpeak beltpacks can have their keys assigned to any Channel, Group or Interface Port on the system.


Dante, Analog Audio & Control - Interfacing

FreeSpeak Edge Base Station can interface to a variety of 3rd party audio and intercom systems with audio interface ports assignable to any Channel, Group, FreeSpeak Beltpack and FreeSpeak Edge Base Station keyset on the system:

  • Dante audio network interfaces allow any Dante input or output to connect to FreeSpeak Edge Base Station. 
  • 4-Wire provides the ability to connect analog line-level audio inputs and outputs to FreeSpeak Edge Base Station.
  • 2-Wire Partyline allows interfacing to existing analog partyline intercom system infrastructures or to add Partyline user stations or interfaces using FreeSpeak Edge Base Station’s built in power supply.
  • GPIO provides Inputs and Relay Outputs for system control. Inputs allow activation of audio crosspoints and call signals, while Outputs can be activated upon key presses, audio crosspoints and or call signals configurable in FreeSpeak Edge Base Station’s Logic configurator.

Intercom User Station

FreeSpeak Edge Base Station’s front panel user station provides four keysets on large, high resolution, color touch screens, assignable to any Channel, Group, FreeSpeak beltpack, Program Audio or Stage Announce on the FreeSpeak Edge Base Station system. The user station is provisioned with a headset connection in addition to All Call, Stage Announce and Remote Mic Kill.


System Configuration

FreeSpeak Edge Base Station front panel menus provide the ability to configure the basic system configuration using an interface consisting of color touch screens coupled with tactile rotary encoders and buttons. With the front panel, wireless beltpacks and transceivers can be added to the system, 2-Wire connections can be nulled and network addresses configured. FreeSpeak Edge Base Station’s Core Configuration Manager™ (CCM) is an integrated, browser-based configuration utility enabling rapid setup, configuration and monitoring of the system.
