Wireless 

FreeSpeak II Base Station supports the FreeSpeak II family of wireless intercom, including 1.9 GHz and 2.4 GHz frequency bands which can be concurrently deployed on an FreeSpeak II Base Station system. FreeSpeak antenna transceivers, connected via E1 CAT/Fiber plug and play cable connections 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. 

 

Partyline, Analog Audio & Control - Interfacing 

FreeSpeak II 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 II Base Station keyset on the system: 

• 4-Wire provides the ability to connect analog line-level audio inputs and outputs to FreeSpeak II Base Station. 

• 2-Wire Partyline allows interfacing to existing analog partyline intercom system infrastructures or to add Partyline user stations or interfaces using FreeSpeak II Base Station’s built in power supply. 

• Program Audio Input provides a line level analog audio input, on an XLR connection, with assignability to any keyset or channel. 

• Stage Announce Output a line level analog audio output, on a XLR connection with assignability to any keyset or channel. 

• GPIO provides Inputs and Relay Outputs for system control. Inputs allow activation of audio crosspoints while Outputs can be activated upon key presses, audio crosspoints and or call signals configurable in FreeSpeak II Base Station’s Logic Event configurator. 

Intercom User Station 

FreeSpeak II Base Station’s front panel user station provides four keysets assignable to any Channel, Group, FreeSpeak beltpack, Program Audio or Stage Announce on the FreeSpeak II 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 & Monitoring 

FreeSpeak II Base Station front panel menus provide the ability to configure system configuration using an interface consisting of high contrast screens coupled with tactile rotary encoders and buttons. With the front panel, the status and utilization of all transceivers and beltpacks can be monitored. FreeSpeak II Base Station’s Core Configuration Manager™ (CCM) is an integrated, browser-based configuration utility enabling rapid setup, configuration and monitoring of the system. 

 

Scalability  

FreeSpeak II Base Station is available for 5 or 25 beltpack system with a field upgrade option. 

FreeSpeak Architecture

• The architecture employs a client-server model where the System Core/Base functions as the central audio engine and configuration server of the system. Beltpacks act as clients, offloading all mixing and routing logic to the Core/Base while providing audio input and output to the system.
• The Beltpack serves as the primary user interface, sending routing and volume commands to the System Core/Base for execution. The Core/Base processes these requests centrally and immediately updates the Beltpack’s local display and tallies to reflect the active system state.
• The system uses either the 1.9GHz DECT protocol or 2.4GHz FHSS, employing Time Division Multiplexing, for wireless transmission.
• Devices connect via a pairing mechanism where the Beltpack identifies and joins the system by detecting transceiver beacons that match its stored System ID.
• Roaming is entirely beltpack-driven, with the beltpack autonomously monitoring RF conditions to trigger connection changes. It performs a seamless “make-before-break” handoff, crossfading audio between transceivers before releasing the old link to ensure continuity.
• E1 Transceivers bridge the wireless transmission to the wired by converting wireless audio into E1 multiplexed point-to-point connections for connection to System Core/Base along with synchronization and power.
