The ARCAM PA240 is a two-channel power amplifier designed to deliver high levels of performance for both music and home theater applications. Utilizing ARCAM's proprietary Class G amplification technology, it combines the sonic benefits of low-level Class A operation with the efficiency and dynamic capability of higher-voltage power rails when greater output is required.

Delivering 225 watts per channel into 8 ohms, the PA240 is capable of driving a wide range of loudspeakers with authority and control. Its high-current design provides substantial dynamic headroom, allowing the amplifier to reproduce demanding musical passages and cinematic soundtracks with precision and impact.

For systems requiring additional power, the PA240 can be configured in bridged mode, increasing output capability for use with more demanding loudspeakers or dedicated channels within a larger home cinema installation. This flexibility makes it suitable for both stereo listening systems and multi-channel environments.

Balanced XLR and unbalanced RCA inputs ensure compatibility with a variety of preamplifiers, AV processors, and integrated systems. Combined with a substantial toroidal power supply and carefully engineered Class G architecture, the PA240 is designed to deliver clean, detailed, and controlled amplification across a wide range of applications.
