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. In keeping with tradition, the SR amplifiers confirm their vocation for versatility by including on all models a complete filter section, suitable for any kind of audio system configuration. The controls, protected by a satin-finished aluminium panel, are located on the top panel of the amplifier, so that they can be easily reached from above, even after the product has been installed. When the system includes an Audison bit processor, the filter section can be totally excluded.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eSpecifications\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 \/ 2 x 25A\u003c\/li\u003e\n\u003cli\u003eOperating power supply voltage - 6.5 ÷17 VDC\u003c\/li\u003e\n\u003cli\u003eIdling current - 1.7 A\u003c\/li\u003e\n\u003cli\u003eIdling current when off - 0.09 mA\u003c\/li\u003e\n\u003cli\u003eConsumption @ 14.4 VDC, 2Ω, Max Musical Power - 40 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 id=\"VOKJXV3\"\u003e\u003cstrong\u003eAmplifier Stage\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003eDistortion - THD @ 100 Hz, 4Ω, 70% Rated Power - 0.08 %\u003c\/li\u003e\n\u003cli\u003eBandwidth A - 10 Hz ÷ 35 kHz\u003c\/li\u003e\n\u003cli\u003eS\/N ratio A - 105 dBA\u003c\/li\u003e\n\u003cli\u003eDamping factor A - 200\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 - 880 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 130 W x 4 (4Ω)\u003c\/li\u003e\n\u003cli\u003e4Ch 220 W x 4 (2Ω)\u003c\/li\u003e\n\u003cli\u003e3Ch 120 W x 2 (4Ω) + 480 W x 1 (4Ω)\u003c\/li\u003e\n\u003cli\u003e3Ch 220 W x 2 (2Ω) + 440 W x 1 (4Ω)\u003c\/li\u003e\n\u003cli\u003e2Ch 450 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: 125 W x 4 Ch\u003c\/li\u003e\n\u003cli\u003eSN ratio (ref. 1W output) - SN ratio (ref. 1W output): 83 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 - Front Ch Filters - Full Hi-pass: 50 ÷ 3.2k Hz @ 12 dB\/Oct.\u003c\/li\u003e\n\u003cli\u003eFilter Pass B - Front Ch Filters - Full Lo-pass: 50 ÷ 3.2k Hz @ 12 dB\/Oct.\u003c\/li\u003e\n\u003cli\u003eFilter Pass C - Rear Ch Filters - Full Hi-pass: 50 ÷ 3.2k Hz @ 12 dB\/Oct.\u003c\/li\u003e\n\u003cli\u003eFilter Pass D - Rear 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 Sub CH - (-20 ÷ 6) dB\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":56737476542846,"sku":"SR4.500","price":262.49,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0969\/1394\/9054\/files\/sr4.500.jpg?v=1766258549","url":"https:\/\/www.caraudiotrade.com\/products\/audison-sr-4-500-4-channel-amplifier-with-crossover-130-wrms-x-4","provider":"Car Audio Trade","version":"1.0","type":"link"}
