Arcam PA410 4 Channel Power Amplifier

The Arcam PA410 is a high‑performance power amplifier engineered to provide robust, four‑channel amplification with the clarity and musicality expected from a premium audio brand. Designed with a toroidal transformer, paralleled transistor output stages and an acoustically damped chassis, the PA410 offers stable, low‑noise power delivery, even under demanding loads. With 50 W per channel into 8 Ω (70 W into 4 Ω) across four channels and up to 90 W per channel when only two are driven, it has the headroom and control needed for bookshelf speakers, floor‑standers, or rear/height channels in a home‑cinema setup.

Whether you’re expanding a multi‑channel audio system, powering height or rear speakers for immersive surround formats, or running a multi-room stereo configuration, the PA410 handles each task with authority and composure. Its frequency response is flat and wide (20 Hz–20 kHz), distortion is extremely low (THD around 0.003%), and signal‑to‑noise ratio is excellent, ensuring transparent, detailed playback across genres. The simple, no‑frills design and reliable Class‑AB topology make the PA410 a versatile and dependable backbone for both music and movie systems. For anyone building or upgrading a system, pairing PA410 with a pre‑amp, AV processor or receiver adds expandable, high‑quality amplification without compromising on sound character.

• 4‑channel Class‑AB power amplification — ideal for multi‑room, surround or height/rear speaker use
• 70 W per channel into 4 Ω (50 W per channel 8 Ω) when four channels driven; up to 90 W per channel when two channels driven — ample power and headroom
• Low total harmonic distortion (THD): ~0.003% at 8 Ω, 80% power — clean, accurate, low‑noise playback
• Wide frequency response: 20 Hz–20 kHz ±0.05 dB — balanced, full‑range sound quality
• High signal‑to‑noise ratio (≈ 105 dB, A‑weighted) — minimal background noise for detailed dynamics
• Solid, toroidal‑transformer‑based power supply and acoustically damped chassis — stable power delivery and reduced vibration/noise
• RS 232 control for integration into custom AV installations or multi‑room systems
• Compact footprint — easy integration into AV racks or stand‑alone setups
