Arcam PA240 Class G Power Amplifier
High-power, efficient amplifier with Class G design, capable of bridged mode, balanced inputs & serious output for demanding systems.
Product Overview
The Arcam PA240 offers exceptional amplification performance using Arcam’s HDA Class G design. It provides clean, responsive power with 50 W in Class A for low-level signals and transitions to higher rails for dynamic peaks. Modes include stereo, dual-mono, or bridged operation. Switchable input types (RCA/XLR), a toroidal power supply, and robust build quality make it ideal for high-end stereo or front-channel setups in large rooms, or where amplifier headroom is critical.
