Arcam PA240 Power Amplifier - Pre Loved
The Arcam PA240 is a high-performance, Class G stereo power amplifier designed to deliver both exceptional musical detail and substantial power reserves. Part of Arcam’s premium HDA range, it combines advanced engineering with refined sound quality, making it a superb partner for high-end music systems and home theatre setups alike.
At its heart, the PA240 utilises Arcam’s innovative Class G amplification technology, offering the first 50 watts in pure Class A for a smooth and natural sound at everyday listening levels, while seamlessly switching to higher voltage rails when extra power is required. This ensures effortless drive and control over a wide range of loudspeakers, maintaining clarity, precision, and musicality even during the most dynamic passages.
With 225 watts per channel into 8 ohms and 380 watts into 4 ohms, the PA240 has ample headroom for both demanding speakers and high-level listening. For even greater performance, the amplifier can be bridged to deliver a powerful 790 watts into a single 8-ohm load, making it a versatile solution for both stereo and mono applications. The result is an amplifier equally at home driving a pair of reference hi-fi loudspeakers as it is powering the front channels of an advanced home theatre system.
Connectivity is designed to suit both audiophiles and integrators, with balanced XLR and unbalanced RCA inputs ensuring compatibility with a wide range of preamplifiers and processors. Switchable stereo, dual mono, and bridged modes allow for flexible system configurations, while 12V triggers, RS-232, and Ethernet control provide seamless integration into custom installations.
The PA240 is built around a robust toroidal transformer and housed in a solid, acoustically damped chassis to reduce vibration and maintain signal purity. Careful attention to circuit design and component quality ensures an ultra-low noise floor, excellent dynamic range, and a frequency response that remains flat and accurate across the audible spectrum.
Combining power, refinement, and flexibility, the Arcam PA240 is a sophisticated amplifier that brings music and movies to life with authority, precision, and effortless control.
