Developed in collaboration with ARCAM co-founder John Dawson, this anniversary model represents a significant advancement in the company's amplifier design. As ARCAM's first dual-mono Class G integrated amplifier, the A50 Signature delivers 150 watts per channel into 8 ohms and 220 watts per channel into 4 ohms, providing the dynamic power and control needed to bring demanding music passages to life.\u003c\/p\u003e \u003cp\u003eAt the heart of the A50 Signature is ARCAM's most advanced Class G amplifier architecture to date. Rather than sharing major power supply and amplification components between channels, each channel operates through an independent amplifier module with dedicated transformer windings, power regulation, reservoir capacitors, Class G lifter circuitry, and an output-stage heatsink. This dual-mono construction is designed to minimize unwanted interaction between left and right channels, improve channel separation, and preserve musical detail. The result is an amplifier engineered for precise stereo imaging, low noise, and effortless dynamics across a wide range of loudspeakers.\u003c\/p\u003e \u003cp\u003eThe A50 Signature is equally sophisticated when handling digital audio. Its premium ESS ES9039Q2M digital-to-analog converter provides high-resolution playback through USB-C, coaxial, and optical digital connections. The USB-C audio input supports PCM audio up to 32-bit\/384kHz, making it an excellent choice for connecting a computer or compatible digital music source. HDMI eARC\/ARC brings the same high-quality two-channel amplification to television audio, allowing listeners to enjoy movies, shows, and concerts through their stereo speakers. Selectable DAC filters provide additional flexibility for tailoring digital playback to individual preferences.\u003c\/p\u003e \u003cp\u003eFor vinyl enthusiasts, the ARCAM A50 Signature features a newly designed Class A phono stage with dedicated moving magnet (MM) and moving coil (MC) inputs. Adjustable cartridge loading options help owners optimize performance with a wide variety of compatible turntables and cartridges. Three stereo RCA line inputs and a balanced stereo XLR input accommodate additional analog components, including CD players, external DACs, and dedicated music streamers.\u003c\/p\u003e \u003cp\u003eModern wireless listening is another major strength of the A50 Signature. Bluetooth 5.4 supports high-quality wireless audio with aptX, aptX HD, aptX Lossless, Snapdragon Sound, Bluetooth LE Audio, and Auracast capabilities. Bluetooth audio can be received from compatible source devices or transmitted to compatible wireless headphones. A dedicated 6.3mm wired headphone connection also provides private listening without Bluetooth.\u003c\/p\u003e \u003cp\u003eDesigned to serve as the centerpiece of an evolving hi-fi system, the A50 Signature includes stereo preamplifier outputs for connecting an external power amplifier or powered subwoofer. A dedicated preamplifier mode and configurable processor mode also provide flexible integration with larger stereo and home theater systems. With substantial Class G power, comprehensive connectivity, and the engineering heritage of ARCAM's Radia family, the A50 Signature is a compelling integrated amplifier for serious music listeners who want reference-level features without sacrificing everyday convenience.\u003c\/p\u003e \u003ch4\u003eWhat It's Great At:\u003c\/h4\u003e \u003cul\u003e \u003cli\u003e\n\u003cstrong\u003ePowerful,

ARCAM A50 Signature delivers 150 watts per channel into 8 ohms with both channels driven across the 20Hz–20kHz frequency range. It also produces 220 watts per channel into 4 ohms at 1kHz, giving it substantial output capability for a wide range of compatible passive loudspeakers. Its Class G amplifier design is engineered to combine efficiency with the power reserve required for dynamic musical passages.\u003c\/p\u003e \u003c\/dd\u003e \u003cdt\u003e\u003cstrong\u003eWhat makes the A50 Signature's dual-mono Class G amplifier different?\u003c\/strong\u003e\u003c\/dt\u003e \u003cdd\u003e \u003cp\u003eThe A50 Signature is ARCAM's first dual-mono Class G integrated amplifier. Unlike conventional stereo designs that share major amplifier and power supply components, each channel has its own dedicated amplifier module, transformer winding, power regulation, reservoir capacitors, Class G lifter stage, and output-stage heatsink. This construction helps reduce unwanted interaction between channels and supports excellent stereo separation, low noise, and precise musical reproduction.\u003c\/p\u003e \u003c\/dd\u003e \u003cdt\u003e\u003cstrong\u003eCan I connect both moving magnet and moving coil turntables to the ARCAM A50 Signature?\u003c\/strong\u003e\u003c\/dt\u003e \u003cdd\u003e \u003cp\u003eYes. The A50 Signature includes a built-in Class A phono stage with separate inputs for moving magnet (MM) and moving coil (MC) cartridges, eliminating the need for an external phono preamplifier in many systems. It also offers adjustable MM load capacitance and MC load impedance settings, allowing listeners to optimize the phono stage for compatible cartridge requirements.\u003c\/p\u003e \u003c\/dd\u003e \u003cdt\u003e\u003cstrong\u003eCan I connect my television to the A50 Signature using HDMI eARC?\u003c\/strong\u003e\u003c\/dt\u003e \u003cdd\u003e \u003cp\u003eYes. The A50 Signature includes an HDMI eARC\/ARC input that connects to a compatible television's corresponding HDMI audio return port. This allows TV sound to play through connected stereo speakers, with automatic HDMI switching available on compatible systems. The amplifier supports two-channel PCM audio rather than Dolby Digital, DTS, or other multichannel encoded formats, so the television should be configured to output stereo PCM.\u003c\/p\u003e \u003c\/dd\u003e \u003cdt\u003e\u003cstrong\u003eWhat digital and analog audio sources can I connect to the A50 Signature?\u003c\/strong\u003e\u003c\/dt\u003e \u003cdd\u003e \u003cp\u003eThe A50 Signature offers three stereo RCA line inputs, one balanced stereo XLR input, separate MM and MC phono inputs, two coaxial digital inputs, one optical input, HDMI eARC\/ARC, and a USB-C digital audio input. Its ESS ES9039Q2M DAC supports high-resolution PCM playback up to 32-bit\/384kHz through USB-C, making it suitable for computers and compatible digital music sources. Network music streaming can also be added using an external music streamer connected through an appropriate audio input.\u003c\/p\u003e \u003c\/dd\u003e \u003cdt\u003e\u003cstrong\u003eDoes the A50 Signature support Bluetooth music streaming and wireless headphones?\u003c\/strong\u003e\u003c\/dt\u003e \u003cdd\u003e \u003cp\u003eYes. Bluetooth 5.4 allows the amplifier to receive audio from compatible smartphones, tablets, and other Bluetooth devices, while also supporting audio transmission to compatible Bluetooth headphones. Supported technologies include aptX, aptX HD, aptX Lossless, Snapdragon Sound, Bluetooth LE Audio, and Auracast. Actual codec availability and audio quality depend on the capabilities of the connected devices, and Bluetooth input and output cannot operate simultaneously.\u003c\/p\u003e \u003c\/dd\u003e \u003cdt\u003e\u003cstrong\u003eCan I use wired headphones or connect a powered subwoofer to the ARCAM A50 Signature?\u003c\/strong\u003e\u003c\/dt\u003e \u003cdd\u003e \u003cp\u003eYes. A dedicated front-panel 6.3mm headphone output supports compatible wired headphones with impedances from 16 ohms to 2k ohms. The amplifier also includes stereo RCA preamplifier outputs that can be used with an external power amplifier or a powered subwoofer that accepts a suitable line-level signal. Wired headphone use automatically mutes the speakers and preamplifier outputs by default, although this behavior can be changed in the settings menu.\u003c\/p\u003e \u003c\/dd\u003e \u003cdt\u003e\u003cstrong\u003eCan the ARCAM A50 Signature be integrated into a larger hi-fi or home theater system?\u003c\/strong\u003e\u003c\/dt\u003e \u003cdd\u003e \u003cp\u003eYes. The A50 Signature offers stereo preamplifier outputs, a dedicated preamp mode, and a configurable processor mode for system integration. Processor mode assigns a fixed volume to a selected analog input, allowing the amplifier to work with a compatible AV receiver or surround processor in a combined stereo music and home theater system. Phono inputs cannot be assigned to processor mode, and the fixed-volume level should be configured carefully during setup.\u003c\/p\u003e \u003c\/dd\u003e \u003c\/dl\u003e \u003ch4\u003eARCAM A50 Signature Downloads:\u003c\/h4\u003e \u003cp\u003e\u003ca href=\"https:\/\/storage.googleapis.com\/lupublic\/ARCAM-A50-Signature-Owners-Manual.pdf\" title=\"ARCAM A50 Signature Owner's Manual\"\u003eARCAM A50 Signature Owner's Manual\u003c\/a\u003e\u003cbr\u003e\u003ca href=\"https:\/\/storage.googleapis.com\/lupublic\/ARCAM-A50-Signature-Spec-Sheet.pdf\" title=\"ARCAM A50 Signature Spec Sheet\"\u003eARCAM A50 Signature Spec Sheet\u003c\/a\u003e\u003c\/p\u003e","brand":"Arcam","offers":[{"title":"Default Title","offer_id":62895035875487,"sku":"ARC-RADIA-A50-BLK","price":2999.95,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0495\/6910\/4031\/files\/d483df8d-c82a-47c1-8260-4c5cc553082e.jpg?v=1792709694","url":"https:\/\/listenup.com\/products\/arcam-a50-signature-class-g-integrated-amplifier","provider":"ListenUp","version":"1.0","type":"link"}
