The Fonestar LUX-4200 is a low impedance, multi-channel Class D power amplifier designed for professional installations that demand power, flexibility and reliability. Its four independent channels deliver 4 x 200 W RMS at 8 Ω or 4 x 400 W RMS at 4 Ω, and can be bridged to 2 x 800 W RMS at 8 Ω, making it a versatile choice both for zone-distributed systems and for applications requiring higher power output.
Each channel can be set up independently with its own gain, input sensitivity and HPF/LPF filtering, so the amplifier can be tailored precisely to the speakers and the space. It is well suited to sound system projects in commercial, educational, corporate and cultural spaces, including worship centres, hospitality venues, retail, sports facilities, hotels and transport stations.
