The Fonestar LUX-4200 is a 4-channel Class-D low-impedance power amplifier delivering 4 x 200 W RMS into 8 Ω (4 x 400 W RMS into 4 Ω), in a compact 19" rack format. Each channel can be set to stereo, parallel or bridge mode, with independent gain, input sensitivity and HPF/LPF filters. It has professional XLR and Euroblock connections, an emergency input with priority, remote mute, auto-standby and ground lift.
- 4 x 200 W RMS @ 8 Ω / 4 x 400 W RMS @ 4 Ω (bridge 2 x 800 W RMS @ 8 Ω)
- Class-D, 4 independent channels, 19" rack (430 x 95 x 370 mm)
- HPF/LPF filters and selectable 4 Ω/8 Ω outputs per channel
- XLR and Euroblock inputs, speaker and Euroblock outputs
- Emergency input with priority, remote mute, auto-standby and ground lift
Ideal for low impedance speaker systems in bars, restaurants, retail, education, corporate and cultural spaces.
