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. \u003c\/p\u003e\n\u003cp\u003eWhen the system includes an Audison bit processor, the filter section can be totally excluded.\u003c\/p\u003e\n\u003cp\u003eAudison USS\u003c\/p\u003e\n\u003cp\u003eThanks to the integration of Audison USS (Universal Speakers Simulator) technology in the high level inputs, the SR amplifiers can also be conveniently connected to OEM sources equipped with the 'speaker load detection' function, which monitors the presence of a low impedance load enabling the audio outputs.\u003c\/p\u003e\n\u003cp\u003eAudison SR 4.300 allows multiple connectivity\u003c\/p\u003e\n\u003cp\u003eAll models have balanced high-level inputs for connecting to the OEM headunit speaker output and a low-level RCA for after-market speakers. \u003c\/p\u003e\n\u003cp\u003eWhen using the high-level input, the ART (Automatic Remote On\/Off) function can be enabled to control the amplifiers' power-up with the headunit's power button. In addition, there is a remote IN \/ OUT socket to allow control of multiple amplifiers in cascade that turn on when needed.\u003c\/p\u003e\n\u003cp\u003eThrough the PRE-OUT signal using the Speaker-IN socket it is possible to interface the amplifier with OEM sources that only have amplified outputs, allowing for system expansion.\u003c\/p\u003e\n\u003cp\u003eAMPLIFIER TECH DATA\u003c\/p\u003e\n\u003cp\u003eChannels4\u003c\/p\u003e\n\u003cp\u003eClassD-Class\u003c\/p\u003e\n\u003cp\u003eHi Level InputYes\u003c\/p\u003e\n\u003cp\u003eLow Level InputYes\u003c\/p\u003e\n\u003cp\u003eDigital InputNo\u003c\/p\u003e\n\u003cp\u003ePower supply voltage \/ fuse11 ÷ 15 VDC \/ 1 x 30A\u003c\/p\u003e\n\u003cp\u003eOperating power supply voltage6.5V ÷17 VDC\u003c\/p\u003e\n\u003cp\u003eIdling current1.6 A\u003c\/p\u003e\n\u003cp\u003eIdling current when off0.03 mA\u003c\/p\u003e\n\u003cp\u003eConsumption @ 14.4 VDC, 2Ω, Max Musical Power25 A\u003c\/p\u003e\n\u003cp\u003eRemote OUT6.5 ÷ 15 VDC (150 mA)\u003c\/p\u003e\n\u003cp\u003eRemote IN6.5 ÷ 15 VDC (1 mA)\u003c\/p\u003e\n\u003cp\u003eART - Automatic Remote Turn on\/off from OUTPUT BTL speakers (Selectable)1.5 ÷ 7 VDC\u003c\/p\u003e\n\u003cp\u003eAMPLIFIER STAGE\u003c\/p\u003e\n\u003cp\u003eDistortion - THD @ 100 Hz, 4Ω, 70% Rated Power0.03%\u003c\/p\u003e\n\u003cp\u003eBandwidth A10Hz ÷ 35 kHz\u003c\/p\u003e\n\u003cp\u003eS\/N ratio A100 dBA\u003c\/p\u003e\n\u003cp\u003eDamping factor A150\u003c\/p\u003e\n\u003cp\u003eInput sensitivity Pre-In0.2 ÷ 5 VRMS\u003c\/p\u003e\n\u003cp\u003eInput sensitivity Speaker-In0.8 ÷ 20 VRMS\u003c\/p\u003e\n\u003cp\u003eTotal Power RMS520 W\u003c\/p\u003e\n\u003cp\u003eMinimum load impedance@ 4Ch: 2Ω\u003c\/p\u003e\n\u003cp\u003e@ 3Ch: 2Ω + 2Ω + 4Ω\u003c\/p\u003e\n\u003cp\u003e@ 2Ch: 4Ω\u003c\/p\u003e\n\u003cp\u003eOutput Power (RMS) @14.4 VDC, 1% THD4Ch 85 W x 4 (4Ω)\u003c\/p\u003e\n\u003cp\u003e4Ch 130 W x 4 (2Ω)\u003c\/p\u003e\n\u003cp\u003e3Ch 80 W x 2 (4Ω) + 250 W x 1 (4Ω)\u003c\/p\u003e\n\u003cp\u003e3Ch 130W x 2 (2Ω) + 260 W x 1 (4Ω)\u003c\/p\u003e\n\u003cp\u003e2Ch 250 W x 2 (4Ω)\u003c\/p\u003e\n\u003cp\u003eAdjustable CrossoverYes\u003c\/p\u003e\n\u003cp\u003eCEA SPECIFICATIONS\u003c\/p\u003e\n\u003cp\u003eOutput power @ 4Ω, 1% THD+N, 14.4 VOutput power @ 4Ω, 1% THD+N, 14.4 V: 75 W x 4 Ch\u003c\/p\u003e\n\u003cp\u003eSN ratio (ref. 1W output)SN ratio (ref. 1W output): 82 dBA\u003c\/p\u003e\n\u003cp\u003eINPUTS\u003c\/p\u003e\n\u003cp\u003eInput TypePre-In \/ Speaker-In\u003c\/p\u003e\n\u003cp\u003eFilters OutputsPRE OUT full range (Input A)\u003c\/p\u003e\n\u003cp\u003eFilter Pass ACh Filters: - Full Hi-pass: 50 ÷ 3.2k Hz @ 12 dB\/Oct.\u003c\/p\u003e\n\u003cp\u003eFilter Pass BCh Filters: - Lo-pass: 50 ÷ 3.2k Hz @ 12 dB\/Oct.\u003c\/p\u003e\n\u003cp\u003eFilter Pass CCh Filters: - Full Hi-pass: 50 ÷ 3.2k Hz @ 12 dB\/Oct.\u003c\/p\u003e\n\u003cp\u003eFilter Pass DCh Filters: - Lo-pass: 50 ÷ 3.2k Hz @ 12 dB\/Oct.\u003c\/p\u003e\n\u003cp\u003eChannel MonoA\/B Ch MONO IN (on\/off) Yes\u003c\/p\u003e\n\u003cp\u003eInputs\/Outputs Bass BoostB Ch (0 ÷12) dB\u003c\/p\u003e\n\u003c\/div\u003e","brand":"Audison","offers":[{"title":"Default Title","offer_id":53493562638717,"sku":"SR 4.300 V2","price":349.0,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0561\/6998\/8144\/files\/32_dddb3072-d490-49de-a3a4-5211e6910204.jpg?v=1727660489","url":"https:\/\/www.bigsoundslowskirts.com\/products\/audison-sr-4-300-amplifier-520-w-total-power-4-x-130-w-2ohm_176307183030_","provider":"BigsSoundsLowSkirts","version":"1.0","type":"link"}
