Fohhn Audio AG is a German professional sound reinforcement manufacturer with over 30 years of experience, headquartered in Nürtingen near Stuttgart. The company is valued worldwide for complete audio systems — from compact architectural speakers, through concert systems with Beam Steering technology, to multi-channel power amplifiers. All manufacturing takes place in Germany, compliant with ISO 9001 and ISO 14001 certifications.
The MA-4.600 is a four-channel power amplifier from the MA series, delivering 4 × 600 W RMS at 4 Ohm. This model sits between the compact AM-4.4 and the flagship MA-4.100, offering an optimal power-to-price ratio for medium and large sound installations. Class D technology ensures high energy efficiency, translating to lower heat output and reduced operating costs compared to traditional analogue amplifiers.
The amplifier features a comprehensive protection package including overload, short-circuit, and overheat protection, along with an intelligent cooling system with automatic fan speed regulation. Channel bridging capability allows flexible configuration to match each installation’s specific needs. The 19″ rack-mount enclosure (2U) with balanced XLR inputs and Speakon outputs ensures professional integration with existing systems.
The MA-4.600 is the ideal complement to Fohhn AT-08 and XT-10 speakers, creating a balanced sound system with precisely matched power parameters. Combined with XS series subwoofers — such as the XS-22 — this amplifier forms the core of a complete single-manufacturer sound system, eliminating compatibility issues and ensuring optimal sound quality in theatres, churches, conference centres, and events.
