Arcam PA410 4x50W Class AB Power Amplifier

Arcam PA410 4x50W Class AB Power Amplifier

Four-channel Class AB power amplifier delivering 50W per channel into 8 ohms with balanced XLR and RCA inputs for surround, height, multi-zone and custom-install amplification.

The Arcam PA410 is a four-channel Class AB power amplifier built for systems that need additional channels without adding another oversized chassis. It is a particularly neat fit for height speakers, surround channels, secondary zones or mixed Arcam separates systems.

The important correction here is that the PA410 is Class AB, not Class G. Its role is clean, reliable multi-channel power rather than the higher-output Class G architecture used in Arcam's larger PA models.

Four Channels of Class AB Power

Straightforward amplification for extra theatre or zone channels

Arcam rates the PA410 at 50W per channel into 8 ohms with all four channels driven across 20Hz-20kHz at the published distortion condition. With two channels driven, available output rises, giving the amplifier useful flexibility depending on the system role.

Balanced and Unbalanced Inputs

Easy integration with processors and preamplifiers

Each channel can be fed from RCA or balanced XLR, making the PA410 suitable for both conventional domestic systems and more structured rack installations.

Custom-Install Control

Built to behave properly in a rack

RS232 and system-control connectivity help the PA410 integrate into professionally controlled systems. As with any multi-channel amplifier, ventilation and service access should be planned rather than treated as an afterthought.

Important Notes

• This is a power amplifier and requires a preamplifier, AV processor or receiver with suitable pre-outs.
• Provide adequate ventilation, especially in a rack with multiple power amplifiers.

The Audio Experts Take

The PA410 is a very sensible way to add four clean channels to a separates-based theatre without overbuying output for height or surround duties. It also works well for multi-zone systems where balanced inputs and rack control are useful. The key is matching its output to the speakers and role rather than treating every channel in a cinema as if it needs the same power.
