The Fonestar SCF-550 is the Control Unit for an amplified conference system, offering a simplified and powerful solution for managing debates and meetings by integrating the control functions and amplification into a single device.
Integrated Amplifier: Equipped with a powerful built-in amplifier (50 + 50 W RMS at 4-16 Ω), which reduces the total number of devices required for installation.
Microphone Capacity: Allows connection of up to 64 microphones in total via its 4 microphone groups (DIN 8 connectors). The system is extendable up to 250 microphones (inquire for details).
Active Microphone Control: Provides flexible control over the discussion by allowing selection of the maximum number of active microphones: 1, 2, 3, 5, or no limit.
Versatile Connectivity: Offers a variety of inputs and outputs for connecting auxiliary sources, recording, and effects:
Inputs: 1 unbalanced mic. (6.3 mm jack), 1 aux (RCA), 1 efx in (6.3 mm jack).
Outputs: 1 balanced master (XLR for recording), 2 line outs (RCA), 1 efx out (6.3 mm jack).
Audio Controls: Comprehensive controls for individual input volumes (Mic.1, Aux, Monitor, Internal Loudspeaker), general volume, and tone control (bass and treble).
Quality & Compliance: Built in compliance with IEC 60914 (Conference Systems) and IEC 61603-7 (Transmission Systems) standards.
Simple Installation: Designed for easy and intuitive setup and operation.
The SCF-550 is perfect for conference and debate settings where integrated amplification and simple management are priorities, including:
