Rotal A50 Signature
Flagship dual-mono Class G integrated amplifier with 150W per channel, ESS DAC, HDMI eARC, USB-C, Bluetooth and MM/MC phono stage.
The ARCAM A50 Signature is a flagship integrated amplifier created to celebrate 50 years of ARCAM amplification expertise. Designed in Cambridge, it introduces ARCAM’s first dual-mono Class G integrated amplifier architecture, combining substantial power with advanced analogue and digital engineering.
Its dual-mono design gives each channel its own self-contained amplifier module, with independent transformer windings, power regulation, reservoir capacitors, Class G lifter stage and output-stage heatsink. This carefully separated architecture is designed to deliver excellent channel separation, low noise and impressive dynamic capability.
The A50 Signature delivers 150W per channel into 8 ohms with both channels driven from 20Hz to 20kHz, increasing to 220W per channel into 4 ohms at 1kHz. Harmonic distortion is rated at just 0.002% at 80% power into 8 ohms at 1kHz.
Digital audio is handled by an ESS ES9039Q2M DAC, with USB-C supporting sample rates up to 384kHz and 32-bit audio. HDMI eARC provides straightforward integration with a compatible television, while other digital inputs support sample rates up to 192kHz.
Vinyl playback is catered for by a built-in Class A MM and MC phono stage, allowing the A50 Signature to accommodate a wide range of turntables and cartridges. Three pairs of RCA analogue inputs provide further connectivity for traditional hi-fi sources.
Bluetooth 5.4 provides both transmitting and receiving functionality, with support for SBC, AAC, aptX, aptX HD, aptX Lossless, LE Audio and Auracast. Wired and wireless headphone listening is also supported.
The ARCAM A50 Signature measures 431 x 344 x 99mm including speaker terminals and feet, with a net weight of 12kg. Maximum power consumption is rated at 700W, while standby consumption is less than 0.5W.
