The JBL SA550 Classic includes the latest Bluetooth AptX®Adaptive technology for hi-res audio over Bluetooth and low latency to ensure audio is in sync with video.\u003c\/p\u003e\n\u003cp\u003eThe advanced amplifier topolgy in the JBL SA550 Classic is called Class G. Class G utilises multiple power supplies where all other amplifiers only use one. The first power supply feeds enough power for the amplifier to deliver 10 Watts per channel, not a lot you might think... but this small amplifier includes a big heatsink that keeps the amplifier stable up to 90 Watts per channel. That enables this first 10 Watts to be delivered in a topology known as Class A, which ordinarily is not very efficient. The benefit is that it involves no switching of any output stage components in and out of the music signal - as normally occurs in any Class AB or Class D amplifier. The result is vanishingly low noise and the purest sound with all micro dynamics and details preserved.\u003c\/p\u003e\n\u003cp\u003eOf course, 10 Watts really isn’t much and so the SA550 can deliver a great deal more. It can deliver a maximum sustained output of 150 Watts per channel with the use of a second, much higher voltage power supply, and this is where the amplification in the SA550 is incredibly inventive. If that second power supply was simply switched into circuit when required, it would induce nasty distortion, and this would be harmonic too - quite unpleasant. So the SA550 includes a set of high speed “lifters” which gradually raise the power delivered to the amplifier, tracking the music signal and mainaining a 5 Volt head room. This allows the benefits of Class G amplification to be realised, whilst eliminating the downsides and powering any speaker system effortlessly.\u003c\/p\u003e\n\u003cp\u003eAll that smart amplification can be enjoyed from three digital and four analog inputs, including a moving magnet phono input for turntable. The digital inputs include a high resolution, ultra high-fidelity DAC with the highest performance ESS DAC chip at heart. The SA550 is a throw-back to the late 1960’s on the outside. But with Hi-res Bluetooth technology, efficient amplification andexceptional musical performance, the SA550 is a modern classic rooted in today’s best technologies.\u003c\/p\u003e\n\u003cp\u003e \u003c\/p\u003e\n\u003ch3\u003e\n\u003cstrong\u003eFeatures:\u003c\/strong\u003e\u003cstrong\u003e\u003c\/strong\u003e\n\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eAdvanced integrated amplifier with Classic Styling\u003c\/li\u003e\n\u003cli\u003eBluetooth input with Hi-res AptX®Adaptive technology\u003c\/li\u003e\n\u003cli\u003eWalnut veneer side panels match JBL Classic and Studio Monitor loudspeakers\u003c\/li\u003e\n\u003cli\u003e3 Digital Inputs with Coax and Toslink connections\u003c\/li\u003e\n\u003cli\u003eHigh resolution DAC with ESS ES9038K2M DAC chip\u003c\/li\u003e\n\u003cli\u003e4 analog inputs including MM phono stage\u003c\/li\u003e\n\u003cli\u003eClass G amplifier topology for ultra low distortion\u003c\/li\u003e\n\u003cli\u003ePower output 90W per channel into 8ohms, 150W into 4ohms\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e","brand":"JBL","offers":[{"title":"Default Title","offer_id":57871552610691,"sku":"16539","price":1199.0,"currency_code":"GBP","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0939\/9356\/6595\/files\/16539-1-JBL-SA550-Main-SOUNDCRAFTHIFI.jpg?v=1776944871","url":"https:\/\/www.soundcrafthifi.com\/products\/jbl-sa550-classic-integrated-amplifier-with-bluetooth","provider":"Soundcraft Hi-Fi","version":"1.0","type":"link"}
