{"product_id":"wadia-a315-stereo-power-amplifier","title":"Wadia A315 Stereo Power Amplifier","description":"The Wadia a315 digital stereo amplifier provides 150 watts per channel at 8 ohms or 250 watts per channel at 4 ohms. It shares the same sleek, modern industrial design as the 321 decoding computer, making it a perfect amp to use with the 321. Both will blend nicely with virtually any room styling.\u003cbr\u003e\u003cbr\u003e\n\nAlong with all of their new generation amplifiers, the a315 is able to deliver massive amounts of power directly to your speakers with very little energy wasted in heat dissipation thanks to its electronic switching design. Large cooling fins or noisy fans often found in other high power amplifiers are no longer needed. The result is a greener, compact and energy efficient amplifier.\u003cbr\u003e\u003cbr\u003e\n\nThe a315 features some of the latest technology from Wadia. Frequency Switching Transmission™ (FST) is an adaptive modulation design in the amplifier circuitry that assures full output power is delivered over the entire audio spectrum. Signal Surveyor™ monitors the output signal and stops amplification if unsafe levels of DC voltage are detected, thus protecting your speakers.\u003cbr\u003e\u003cbr\u003e\n\nBoth balanced and unbalanced inputs are available for connecting your other system components. Specially designed 5-way binding posts will securely hold your speaker wire; they are designed for easy finger tightening and come with a special tool if even more snug connections are desired. A trigger input and output makes it simple to control the power state of your entire system when the a315 is turned on\/off. \u003cbr\u003e\u003cbr\u003e \n\n\n\n\nSpecifications:- \u003cbr\u003e\n\n\nPOWER OUTPUT:\n150 watts into 8 ohm loads\n250 watts into 4 ohm loads\u003cbr\u003e\n\nOUTPUT LOAD IMPEDANCE:\n8 ohms or 4 ohms\u003cbr\u003e\n\nRATED POWER BAND:\n20Hz to 20kHz\u003cbr\u003e\n\nTOTAL HARMONIC DISTORTION:\n0.1% maximum harmonic distortion at any level from 250 milliwatts to one-half of rated power output, 20Hz to 20kHz;\n0.5% maximum harmonic distortion at any level from one-half to full rated power output, 20Hz to 20kHz\u003cbr\u003e\n\nDYNAMIC HEADROOM:\n1dB 8 ohm load\n1.6dB 4 ohm load\u003cbr\u003e\n\nFREQUENCY RESPONSE:\n+0, -0.5dB from 20Hz to 20kHz\n+0, -3.0dB from 10Hz to 70kHz\u003cbr\u003e\n\nINPUT SENSITIVITY:\n2.4V Balanced\n1.2V Unbalanced\u003cbr\u003e\n\nA-WEIGHTED SIGNAL TO NOISE RATIO:\n90dB (112dB below rated output) Balanced\n88dB (110dB below rated output) Unbalanced\u003cbr\u003e\n\n\n\nINTERMODULATION DISTORTION:\n0.1% maximum if instantaneous peak power output does not exceed the rated output for any combination of frequencies from 20Hz to 20kHz\u003cbr\u003e\n\nWIDE BAND DAMPING FACTOR:\nGreater than 320, 8 ohm load\nGreater than 160, 4 ohm load\u003cbr\u003e\n\nINPUT IMPEDANCE:\n10K ohms Balanced and Unbalanced\u003cbr\u003e\n\nVOLTAGE GAIN:\n29dB\u003cbr\u003e\n\nTRIGGER INPUT:\n5-15VDC, less than 1mA\u003cbr\u003e\n\nTRIGGER OUTPUT:\n12VDC, 50mA maximum, delayed 0.2 seconds\u003cbr\u003e\n\nOVERALL DIMENSIONS:\nWidth 17-7\/8 inches (45.4 cm)\nHeight 3-3\/8 inches (8.6 cm) including feet\nDepth 20 inches (50.8 cm) including cables\u003cbr\u003e\n\nWEIGHT:\n27 pounds (12.2 kg)\u003cbr\u003e\n\n\nNote: All Specifications are with AC Line voltage of 120V.\n\n\n","brand":"Wadia","offers":[{"title":"Default Title","offer_id":57409671037260,"sku":"WADIAA315","price":2831.67,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/1053\/6891\/2204\/files\/Wadia-A315-front.jpg?v=1777490729","url":"https:\/\/www.stoneaudio.co.uk\/products\/wadia-a315-stereo-power-amplifier","provider":"Stone Audio","version":"1.0","type":"link"}
