The Fonestar SCF-250 is a control unit for a standard wired conference system, designed primarily for rooms already equipped with public address (PA) systems. It facilitates communication among participants and provides the necessary control features for conducting meetings.
System Control Unit: Serves as the central power supply and control hub for the conference system microphones.
Microphone Capacity: Allows connection of up to 64 microphones in total via 4 groups (female DIN 8 connectors).
Active Microphone Control: Includes a selector to set the maximum number of microphones allowed to be simultaneously active during the conference, ensuring organized discussion flow.
Telephone Connection: Features a dedicated RCA input/output to connect a telephone switchboard extension, allowing a remote participant to intervene in the conference.
Audio Outputs: Provides an output signal for recording, external amplification, or distribution, via both XLR and RCA line outputs.
Audio Controls: Includes controls for general volume and a three-band equalizer (bass, mid, and treble) to fine-tune the system's sound quality.
Design and Standards: Built into a compact 1 U 19" rack chassis, complying with IEC 60914 (Conference Systems) and IEC 61603-7 (Transmission Systems) standards.
The SCF-250 is recommended for conference rooms and debate setups where integration with existing PA or external amplification equipment is necessary, including:
