ARCAM's 50th Anniversary Reference Dual-Mono Class G Integrated Amplifier

The Arcam A50 Signature Integrated Amplifier celebrates five decades of ARCAM amplification with the company's first true dual-mono Class G integrated design. Developed in Cambridge, UK, each stereo channel operates as an independent amplifier module with its own transformer winding, power regulation, reservoir capacitors, Class G lifter stage and output-stage heatsink, creating exceptional channel separation, low noise and dynamic control.

Delivering 150 watts per channel into 8 ohms and 220 watts into 4 ohms, the A50 Signature combines formidable loudspeaker-driving ability with a completely redesigned digital and analog platform. An ESS ES9039Q2M DAC, asynchronous USB-C, HDMI eARC, dedicated Class A MM/MC phono circuitry, analog and digital inputs, Bluetooth 5.4 with aptX Lossless and Auracast, plus wired and wireless headphone support make it an exceptionally versatile centerpiece for a reference two-channel system.

Highlights & Benefits

• 150W Per Channel Dual-Mono Class G — ARCAM's most advanced Class G implementation delivers 150 watts into 8 ohms and 220 watts into 4 ohms with both channels driven.
• First ARCAM Dual-Mono Class G Integrated — Each channel receives dedicated transformer windings, regulation, reservoir capacitance, Class G lifter circuitry and its own heatsink.
• ESS ES9039Q2M DAC — A new high-resolution digital section supports USB-C audio up to 32-bit/384kHz along with conventional digital sources and HDMI eARC.
• Class A MM & MC Phono Stage — Built-in phono amplification supports both moving-magnet and moving-coil cartridges for high-quality vinyl playback without an external phono preamp.
• Bluetooth 5.4 with aptX Lossless & Auracast — Advanced wireless audio supports both receiving and transmitting, including compatible wireless headphones.

Technology & Design

True Dual-Mono Class G Architecture — The left and right channels are constructed as self-contained amplifier modules, significantly reducing interaction between channels and providing each side with independent power delivery and thermal management.

Advanced Class G Power Delivery — ARCAM's Class G topology operates from lower supply rails during normal listening and introduces higher-voltage rails only when musical peaks demand additional power, combining strong efficiency with the linearity of a high-quality analog amplifier.

New Digital & Volume-Control Platform — The A50 Signature incorporates newly designed DAC, phono and volume-control circuitry developed specifically to complement its dual-mono amplifier architecture and preserve signal integrity from input to output.

Modern Source Integration — USB-C accommodates high-resolution computer audio, HDMI eARC simplifies premium TV sound, and Bluetooth 5.4 provides Snapdragon Sound, aptX Lossless, LE Audio and Auracast connectivity for compatible wireless devices.
