SPA-240 PA Amplifier

The SPA-240 professional dual-mode amplifier is built for public broadcasting and professional sound reinforcement: one unit supports both high-impedance constant-voltage broadcasting and low-impedance stereo amplification, meeting diverse needs from campus-wide PA to small and medium performances and meetings — an all-round versatile device for commercial sound.

Key Features

Dual Mode, Dual Impedance: Switchable high/low-impedance modes: constant impedance for stage and home audio, constant voltage for malls and parks — one unit serves two scenarios.

4-Zone Constant-voltage Control: Four independently switchable zones plus a master switch for flexible, controllable zone broadcasting.

Hi-fi Monitoring: The low-impedance mode delivers refined sound and doubles as a high-fidelity HIFI monitor.

Industrial-grade Body: Sturdy standard engineering chassis with multiple protection circuits supports 7×24 continuous commercial operation.

Energy-saving & Wide Compatibility: Low power consumption saves electricity cost; compatible with both professional HIFI and PA speakers for new projects and system renovations.
