Designed in Cambridge, UK, this high-performance integrated amplifier combines 150 W per channel into 8 ohms with a fully dual-mono architecture, sophisticated digital conversion, and a newly developed class-A phonostage for both moving magnet and moving coil cartridges.\u003c\/p\u003e\n\u003cp\u003eThe A50 Signature is ARCAM's first dual-mono class-G integrated amplifier. Each channel operates as a self-contained module with independent transformer windings, dedicated power regulation, reservoir capacitors, a class-G lifter stage, and its own output-stage heatsink. This architecture minimizes interference between channels while delivering exceptional channel separation, low noise, and the dynamic capability needed to control demanding loudspeakers.\u003c\/p\u003e\n\u003cp\u003eClass-G amplification combines the sonic advantages of class-A operation at lower output levels with additional power supply rails that engage when the music demands greater output. The A50 Signature takes this approach further with its independently powered channels, delivering 150 W per channel into 8 ohms and 220 W per channel into 4 ohms.\u003c\/p\u003e\n\u003cp\u003eDigital sources benefit from a premium ESS ES9039Q2M DAC, with USB-C connectivity supporting resolutions up to 32-bit\/384 kHz. HDMI eARC provides a convenient connection to a compatible television, while additional digital inputs accommodate CD transports, streamers, and other components. The redesigned analog circuitry includes a class-A MM\/MC phonostage, allowing a wide range of turntables and cartridges to connect directly without an external phono preamplifier.\u003c\/p\u003e\n\u003cp\u003eWireless connectivity is equally comprehensive. Bluetooth 5.4 supports Snapdragon Sound, aptX Lossless, and Auracast, while both wired and wireless headphone listening options provide additional flexibility. Together with its redesigned volume control circuitry and extensive source connectivity, the A50 Signature offers a complete high-performance amplification solution for both traditional and modern music systems.\u003c\/p\u003e\n\u003ch3\u003eFeatures\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eARCAM's first dual-mono class-G integrated amplifier\u003c\/li\u003e\n\u003cli\u003e150 W per channel into 8 ohms and 220 W per channel into 4 ohms\u003c\/li\u003e\n\u003cli\u003eIndependent transformer windings, power regulation, reservoir capacitors, class-G lifter stages, and output-stage heatsinks for each channel\u003c\/li\u003e\n\u003cli\u003eNewly designed class-A MM\/MC phonostage\u003c\/li\u003e\n\u003cli\u003eESS ES9039Q2M DAC with support for up to 32-bit\/384 kHz digital audio via USB-C\u003c\/li\u003e\n\u003cli\u003eHDMI eARC for connection to compatible televisions\u003c\/li\u003e\n\u003cli\u003eThree stereo RCA analog inputs\u003c\/li\u003e\n\u003cli\u003eRedesigned volume control circuitry\u003c\/li\u003e\n\u003cli\u003eBluetooth 5.4 with Snapdragon Sound, aptX, aptX HD, aptX Lossless, and Auracast\u003c\/li\u003e\n\u003cli\u003eBluetooth audio reception and transmission for wireless listening\u003c\/li\u003e\n\u003cli\u003eDedicated headphone output for wired listening\u003c\/li\u003e\n\u003cli\u003eDesigned in Cambridge, UK\u003c\/li\u003e\n\u003cli\u003ePlastic-free packaging\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003eWhat's Included\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eARCAM A50 Signature Integrated Amplifier\u003c\/li\u003e\n\u003cli\u003ePower cord\u003c\/li\u003e\n\u003cli\u003eRemote control with two AAA batteries\u003c\/li\u003e\n\u003cli\u003eQuick Start Guide\u003c\/li\u003e\n\u003cli\u003eImportant Safety Instructions\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003eSpecifications\u003c\/h3\u003e\n\u003cp\u003e\u003cb\u003eAmplifier Type:\u003c\/b\u003e Dual-mono class-G\u003c\/p\u003e\n\u003cp\u003e\u003cb\u003eContinuous Power Output (8 Ohms, 20 Hz–20 kHz, 0.5% THD):\u003c\/b\u003e 150 W per channel\u003c\/p\u003e\n\u003cp\u003e\u003cb\u003eContinuous Power Output (4 Ohms, 1 kHz, 0.5% THD):\u003c\/b\u003e 220 W per channel\u003c\/p\u003e\n\u003cp\u003e\u003cb\u003eHarmonic Distortion (80% Power, 8 Ohms, 1 kHz):\u003c\/b\u003e 0.002%\u003c\/p\u003e\n\u003cp\u003e\u003cb\u003eAnalog Inputs:\u003c\/b\u003e 3 stereo RCA pairs\u003c\/p\u003e\n\u003cp\u003e\u003cb\u003eAnalog Signal-to-Noise Ratio (A-Weighted, Ref. 50 W, 1 V Input):\u003c\/b\u003e 106 dB\u003c\/p\u003e\n\u003cp\u003e\u003cb\u003eAnalog Frequency Response:\u003c\/b\u003e 20 Hz–20 kHz \u003cb\u003e(±0.2 dB)\u003c\/b\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cb\u003ePhonostage:\u003c\/b\u003e class-A, moving magnet and moving coil\u003c\/p\u003e\n\u003cp\u003e\u003cb\u003eMM Phono Input Impedance:\u003c\/b\u003e 47 kilohms + 100 pF\u003c\/p\u003e\n\u003cp\u003e\u003cb\u003ePhono Frequency Response (Ref.
