After numerous listening tests with professionals and enthusiasts, Audison's R\u0026amp;D team decided to adopt a new class D technology called ADT (Audison D-Class Technology) for this line of amplifiers, which has made it possible to considerably reduce their size, totally preserving the audio performance that characterises every Audison design.As far as the electronic design is concerned, every aesthetic and functional detail of the Audison SR 4.300 has been taken care of, resulting in a compact amplifier made of extruded aluminium with rounded corners, which facilitates the installation of the product in narrow spaces. Thanks to the generous heat sinks on the two short sides of the amplifiers, there is no need for internal cooling fans, which often cause noise and dust accumulation.\u003c\/p\u003e\n\u003cp id=\"DU9R6OR\"\u003e\u003cstrong\u003eSpecification\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003eChannels - 4\u003c\/li\u003e\n\u003cli\u003eClass - D-Class\u003c\/li\u003e\n\u003cli\u003eHi Level Input - Yes\u003c\/li\u003e\n\u003cli\u003eLow Level Input - Yes\u003c\/li\u003e\n\u003cli\u003eDigital Input - No\u003c\/li\u003e\n\u003cli\u003ePower supply voltage \/ fuse - 11 ÷ 15 VDC \/ 1 x 30A\u003c\/li\u003e\n\u003cli\u003eOperating power supply voltage - 6.5V ÷17 VDC\u003c\/li\u003e\n\u003cli\u003eIdling current - 1.6 A\u003c\/li\u003e\n\u003cli\u003eIdling current when off - 0.03 mA\u003c\/li\u003e\n\u003cli\u003eConsumption @ 14.4 VDC, 2Ω, Max Musical Power - 25 A\u003c\/li\u003e\n\u003cli\u003eRemote OUT - 6.5 ÷ 15 VDC (150 mA)\u003c\/li\u003e\n\u003cli\u003eRemote IN - 6.5 ÷ 15 VDC (1 mA)\u003c\/li\u003e\n\u003cli\u003eART - Automatic Remote Turn on\/off from OUTPUT BTL speakers (Selectable) - 1.5 ÷ 7 VDC\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003e\u003cstrong\u003eAmplifier Stage\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003eDistortion - THD @ 100 Hz, 4Ω, 70% Rated Power - 0.03%\u003c\/li\u003e\n\u003cli\u003eBandwidth A - 10Hz ÷ 35 kHz\u003c\/li\u003e\n\u003cli\u003eS\/N ratio A - 100 dBA\u003c\/li\u003e\n\u003cli\u003eDamping factor A - 150\u003c\/li\u003e\n\u003cli\u003eInput sensitivity Pre-In - 0.2 ÷ 5 VRMS\u003c\/li\u003e\n\u003cli\u003eInput sensitivity Speaker-In - 0.8 ÷ 20 VRMS\u003c\/li\u003e\n\u003cli\u003eTotal Power RMS - 520 W\u003c\/li\u003e\n\u003cli\u003eMinimum load impedance\u003c\/li\u003e\n\u003cli\u003e@ 4Ch: 2Ω\u003c\/li\u003e\n\u003cli\u003e@ 3Ch: 2Ω + 2Ω + 4Ω\u003c\/li\u003e\n\u003cli\u003e@ 2Ch: 4Ω\u003c\/li\u003e\n\u003cli\u003eOutput Power (RMS) @14.4 VDC, 1% THD\u003c\/li\u003e\n\u003cli\u003e4Ch 85 W x 4 (4Ω)\u003c\/li\u003e\n\u003cli\u003e4Ch 130 W x 4 (2Ω)\u003c\/li\u003e\n\u003cli\u003e3Ch 80 W x 2 (4Ω) + 250 W x 1 (4Ω)\u003c\/li\u003e\n\u003cli\u003e3Ch 130W x 2 (2Ω) + 260 W x 1 (4Ω)\u003c\/li\u003e\n\u003cli\u003e2Ch 250 W x 2 (4Ω)\u003c\/li\u003e\n\u003cli\u003eAdjustable Crossover - Yes\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003e\u003cstrong\u003eCEA Specifications\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003eOutput power @ 4Ω, 1% THD+N, 14.4 V - Output power @ 4Ω, 1% THD+N, 14.4 V: 75 W x 4 Ch\u003c\/li\u003e\n\u003cli\u003eSN ratio (ref. 1W output) - SN ratio (ref. 1W output): 82 dBA\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003e\u003cstrong\u003eInputs\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003eInput Type - Pre-In \/ Speaker-In\u003c\/li\u003e\n\u003cli\u003eFilters Outputs - PRE OUT full range (Input A)\u003c\/li\u003e\n\u003cli\u003eFilter Pass A - Ch Filters: - Full Hi-pass: 50 ÷ 3.2k Hz @ 12 dB\/Oct.\u003c\/li\u003e\n\u003cli\u003eFilter Pass B - Ch Filters: - Lo-pass: 50 ÷ 3.2k Hz @ 12 dB\/Oct.\u003c\/li\u003e\n\u003cli\u003eFilter Pass C - Ch Filters: - Full Hi-pass: 50 ÷ 3.2k Hz @ 12 dB\/Oct.\u003c\/li\u003e\n\u003cli\u003eFilter Pass D - Ch Filters: - Lo-pass: 50 ÷ 3.2k Hz @ 12 dB\/Oct.\u003c\/li\u003e\n\u003cli\u003eChannel Mono - A\/B Ch MONO IN (on\/off) Yes\u003c\/li\u003e\n\u003cli\u003eInputs\/Outputs Bass Boost - B Ch (0 ÷12) dB\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003c\/div\u003e\u003c\/div\u003e\u003c\/div\u003e","brand":"Audison","offers":[{"title":"Default Title","offer_id":56737476575614,"sku":"SR4.300","price":204.16,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0969\/1394\/9054\/files\/audison_sr-4_300-r02_emo.jpg?v=1766258570","url":"https:\/\/www.caraudiotrade.com\/products\/audison-sr-4-300-4-channel-car-compact-high-powered-amplifier-500w","provider":"Car Audio Trade","version":"1.0","type":"link"}
