Designed in Cambridge and developed in collaboration with ARCAM co-founder John Dawson, it honours the brand’s long heritage while looking firmly towards modern music listening.\u003c\/p\u003e\n\n\u003cp\u003eAt the heart of the A50 Signature is ARCAM’s first dual-mono Class G integrated amplifier design. Each channel is built as a fully independent amplifier module, with its own transformer windings, power regulation, reservoir capacitors, Class G lifter stage and output-stage heatsink. This helps deliver excellent channel separation, low noise and powerful, controlled dynamics.\u003c\/p\u003e\n\n\u003cp\u003eWith 150 watts per channel into 8 ohms and 220 watts per channel into 4 ohms, the A50 Signature has the drive and authority needed for serious loudspeakers. Its Class G design combines the refinement associated with lower-power operation with the extra reserves required for demanding musical peaks, giving the amplifier a sound that is clean, confident and expressive.\u003c\/p\u003e\n\n\u003cp\u003eThe A50 Signature is also designed for the way people listen today. It includes a built-in ESS ES9039Q2M DAC, HDMI eARC for TV sound, USB-C for high-resolution digital audio, analogue inputs, and a built-in Class A moving magnet and moving coil phono stage for vinyl. Bluetooth 5.4 with Snapdragon Sound, aptX Lossless, LE Audio and Auracast support also allows high-quality wireless listening with compatible devices.\u003c\/p\u003e\n\n\u003cp\u003eAs the flagship integrated amplifier in ARCAM’s Radia range, the A50 Signature is ideal for customers who want a powerful, flexible and beautifully engineered amplifier that can sit at the centre of a serious music and entertainment system.\u003c\/p\u003e\n\n\u003ch3\u003eKey Benefits\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eFlagship ARCAM integrated amplifier created to celebrate 50 years of ARCAM amplification\u003c\/li\u003e\n\u003cli\u003eDesigned in Cambridge, UK, in collaboration with ARCAM co-founder John Dawson\u003c\/li\u003e\n\u003cli\u003eFirst ARCAM dual-mono Class G integrated amplifier for improved separation, control and dynamic performance\u003c\/li\u003e\n\u003cli\u003e150W per channel into 8 ohms and 220W per channel into 4 ohms provides excellent loudspeaker drive\u003c\/li\u003e\n\u003cli\u003eBuilt-in Class A MM and MC phono stage supports a wide range of turntables and cartridges\u003c\/li\u003e\n\u003cli\u003eESS ES9039Q2M DAC supports high-quality digital playback from modern sources\u003c\/li\u003e\n\u003cli\u003eHDMI eARC input makes it easy to enjoy TV sound through a proper hi-fi system\u003c\/li\u003e\n\u003cli\u003eUSB-C input supports high-resolution audio up to 32-bit \/ 384kHz\u003c\/li\u003e\n\u003cli\u003eBluetooth 5.4 with aptX Lossless, LE Audio and Auracast gives flexible wireless listening options\u003c\/li\u003e\n\u003cli\u003eWired headphone output and wireless headphone support allow private listening\u003c\/li\u003e\n\u003cli\u003ePlastic-free packaging uses natural materials for easier disposal\u003c\/li\u003e\n\u003cli\u003e2 years manufacturer's warranty\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003c\/div\u003e\n\n\u003cdiv id=\"hb-arcam-a50-signature-panel-2\" class=\"hb-panel\"\u003e\n\n\u003ch3\u003eTechnical Specifications\u003c\/h3\u003e\n\n\u003cp\u003e\u003cstrong\u003eProduct Design\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003eProduct Type: Integrated amplifier\u003c\/li\u003e\n\u003cli\u003eSeries: ARCAM Radia\u003c\/li\u003e\n\u003cli\u003eAmplifier Type: Dual-mono Class G\u003c\/li\u003e\n\u003cli\u003eDAC: ESS ES9039Q2M\u003c\/li\u003e\n\u003cli\u003ePhono Stage: Built-in Class A MM and MC phono stage\u003c\/li\u003e\n\u003cli\u003eVolume Control: New design developed for the A50 Signature\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003cp\u003e\u003cstrong\u003ePower Output\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003eContinuous Power Output, 8 Ohms, 20Hz - 20kHz, 2 Channels Driven: 150W per channel\u003c\/li\u003e\n\u003cli\u003eContinuous Power Output, 4 Ohms, 1kHz, 2 Channels Driven: 220W per channel\u003c\/li\u003e\n\u003cli\u003eHarmonic Distortion, 80% Power, 8 Ohms at 1kHz: 0.002%\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003cp\u003e\u003cstrong\u003eAnalogue Inputs\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003eAnalogue Inputs: 3 x stereo RCA pairs\u003c\/li\u003e\n\u003cli\u003eAnalogue Signal-to-Noise Ratio: 106dB, A-weighted, ref. 50W, 1V input\u003c\/li\u003e\n\u003cli\u003eAnalogue Frequency Response: 20Hz - 20kHz, ±0.2dB\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003cp\u003e\u003cstrong\u003ePhono Input\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003eCartridge Support: Moving magnet and moving coil\u003c\/li\u003e\n\u003cli\u003eMM Input Impedance: 47k Ohms + 100pF\u003c\/li\u003e\n\u003cli\u003ePhono Frequency Response: 20Hz - 20kHz, ±1dB, ref.
