BST XL600 - Professional Class AB/H Power Amplifier with SMPS

BST XL600 – Professional Class AB/H Power Amplifier with SMPS

The BST XL600 amplifier integrates switching-mode power supply (SMPS) technology and Class AB/H amplification, delivering high efficiency and superior performance in any professional sound installation. Stable down to 2 Ω, it allows three operating modes—stereo, parallel, and bridge—to accommodate higher-power multi-amplifier or mono configurations. Its progressive air cooling and protections against overheating, VHF, short circuit, and soft-start ensure continuous reliability, while its XLR, jack, and RCA inputs and speakON (Turnlock) or terminal block outputs facilitate versatile integration into racks and PA systems.

Main features

• RMS power per channel: 2× 200 W @ 8 Ω; 2× 300 W @ 4 Ω; 2× 450 W @ 2 Ω
• Bridge mode: 600 W @ 8 Ω; 800 W @ 4 Ω in mono bridge
• Operating modes: Stereo, parallel and bridge.
• Amplification: Class AB and H for maximum fidelity and efficiency.
• Source: SMPS (Switch-Mode Power Supply).
• Cooling: Progressive air ventilation.
• Protections: Overheat, VHF, short circuit, DC detect, soft-start.
