Description
Arcam PA240 Class G Power Amplifier
Exceptional Power, Serious Control
The Arcam PA240 is a high-performance two-channel power amplifier built to deliver effortless dynamics, strong speaker control, and long-term reliability. It uses Arcam’s Class G amplification to combine low distortion at everyday listening levels with substantial power reserves for demanding musical peaks.
This is the kind of amplifier that makes good speakers feel easier to drive, bass feel tighter, and complex music feel more composed.
Class G Amplification With Class A Refinement
The PA240 uses Class G amplification with 50W of Class A operation, giving it a clean, low-noise presentation at normal volumes while keeping serious headroom available when the music demands it. The result is a sound that remains powerful without becoming aggressive, and detailed without becoming sharp.
Built Like a Proper Power Amp
Inside the PA240 you’ll find a toroidal transformer, an acoustically damped chassis, and paralleled transistor output stages. These are the ingredients that support high current delivery, stability under load, and consistently low distortion even when the system is working hard.
Flexible Configuration and Control
The PA240 is designed to fit into real systems. It supports Stereo, Dual Mono, or Bridged operation, and includes switchable RCA or balanced XLR inputs.
For custom installs and integrated control systems, Ethernet and RS232 control are built in, making the PA240 a strong choice for both dedicated listening rooms and more complex rack-based setups.
