{"product_id":"audio-research-i-50-integrated-amplifier","title":"Audio Research I\/50 Integrated Amplifier","description":"The I\/50 Integrated Amplifier is the first product in an all-new series from Audio Research. Functionally \nsimple, visually engaging, and musically sublime - the I\/50 takes music listening to a whole new \nexperience. Hand-crafted in Minnesota, the I\/50 is built with the same attention to detail as all other \nAudio Research products - each one even gets its own listening test with sonic designer, Warren Gehl. \nAvailable in six colors, the I\/50 features Cerakote finishes for a beautiful and long-lasting look. The \nmodular design allows for the installation of two audio modules - a Phono Stage, and a D\/A Converter \n(to come in 2022). The high current, 50 watt per channel amplifier is capable of driving a wide variety \nof speakers. A headphone jack allows for personal listening time.\u003cbr\u003e\u003cbr\u003e\nThe I\/50 is designed to be easy to use, and has three controls on its top panel - Power, Input, and \nVolume. Two LexieTubes® provide display information for input selection and volume. Two matched \npairs of 6550WE vacuum tubes, along with three 6922 tubes, stand in front of the perforated \ntransformer cover. Three single-ended inputs and one XLR input provide connectivity for most systems, \nalong with 4- and 8- Ohm speaker taps to accommodate your speaker of choice. One input can be \nassigned for pass-through function. A full-function metal remote control provides further functionality \nand operation. An optional tube cage will be available.\u003cbr\u003e\u003cbr\u003e\nAs with all Audio Research products, the I\/50 is built entirely in our Minnesota facility by a team of \nskilled technicians and expert craftspeople. Offered in six colours, the I\/50 is the first product completely \nfinished in-house. The Audio Research finishing lab \nencompasses a purpose-built painting facility and \nlaser imaging and marking machines to produce \na luxurious finish normally found only on much \nmore expensive products. The Cerakote \nfinish is not only beautiful, but designed \nto be enduring and easy to \nmaintain. \u003cbr\u003e\u003cbr\u003e\nThe performance of the I\/50 belies its compact design. 50 watts of all-vacuum tube power energize \nyour speakers with beautiful and lifelike music. Designed by the Audio Research engineering team \nand fine-tuned by Warren Gehl, the I\/50 has been given the same level of care and attention as \nour Reference Series products. The ability of the I\/50 to reconstruct a musical experience will thrill \nand excite all who hear it. Thanks to the substantial power supply and high current design, the I\/50 \nprovides controlled and dynamic playback - even on challenging speakers. The Phono module \nprovides 42 dB of gain, allowing a wide choice of moving magnet and high-output moving coil \ncartridges. The D\/A Converter will have multiple connection options and an array of decoding formats \nto accommodate the wide spectrum of music formats and resolutions. The I\/50 is a truly integrated \nproduct while providing renowned Audio Research performance and sound quality.\u003cbr\u003e\u003cbr\u003e\u003cbr\u003e\n\u003ch3\u003eSPECIFICATIONS\u003c\/h3\u003e\nPower Output: 50 watts continuous from 20Hz to 20kHz\u003cbr\u003e \nPower Bandwidth: (-3dB points) 10Hz to 22kHz \u003cbr\u003e\nFrequency Response: (-3dB points at 1 watt) 7Hz to 30kHz\u003cbr\u003e \nInput Sensitivity: 1.25V RMS for rated output. \u003cbr\u003e\nInput Impedance: 100K ohms Balanced, 48K ohms Single Ended\u003cbr\u003e \nOutput Polarity: Non-inverting.
