Each of the four 150 W discrete MOSFET Class A\/B amplifier channels features its own dedicated power transformer, ensuring very low crosstalk and the ability to deliver full rated power with all channels driven.\u003c\/p\u003e\r\n\r\n\u003cp\u003eA class leading input stage provides exceptional common mode rejection across the audio bandwidth, reducing unwanted interference at the input by at least 10,000x. This makes the amplifier ideally suited to electrically noisy environments such as busy machine rooms and complex multi-room facilities. With fan-less convection cooling, the R4-150 Pro operates silently—perfect when installed in control rooms—while thermal and dc offset protection and remote power on\/off trigger inputs allow flexible and reliable installation.\u003c\/p\u003e","brand":"ATC Loudspeakers","offers":[{"title":"Default Title","offer_id":44451354968167,"sku":"502180","price":4990.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0658\/8848\/5479\/files\/atc-r4-150-pro_502180_1.jpg?v=1787096919","url":"https:\/\/vintageking.com\/products\/atc-r4-150-pro-quad-mono-power-amplifier","provider":"Vintage King","version":"1.0","type":"link"}
