With 350 watts per channel into 8 ohms and up to 648 watts into 4 ohms, the RB-1590 delivers a power reserve capable of driving even demanding speakers in large rooms. The design is based on a full Class AB topology, a dual monoblock layout, and a massive power supply with two toroidal transformers and eight British-made slit-foil capacitors.\u003c\/p\u003e\n\u003ch3\u003eHIGHLIGHTS\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e2 x 350 W at 8 ohms \/ 2 x 648 W at 4 ohms\u003c\/li\u003e\n\u003cli\u003eClass AB power amplifier\u003c\/li\u003e\n\u003cli\u003eDual toroidal transformer power supply\u003c\/li\u003e\n\u003cli\u003e8 BHC slit-foil capacitors\u003c\/li\u003e\n\u003cli\u003eDual mono signal architecture\u003c\/li\u003e\n\u003cli\u003eBalanced XLR and unbalanced RCA inputs\u003c\/li\u003e\n\u003cli\u003eDual sets of speaker terminals\u003c\/li\u003e\n\u003cli\u003e12V trigger integration\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003eMASSIVE POWER SUPPLY\u003c\/h3\u003e\n\u003cp\u003eThe RB-1590 is built around a power supply with two large toroidal transformers, custom-made for Rotel. This solution delivers stable voltage and high current capacity even at low impedance and with complex loads.\u003c\/p\u003e\n\u003cp\u003eThe eight BHC slit-foil capacitors act as an energy reservoir and are selected for their low ESR and fast response time, ensuring stable dynamics and minimal voltage compression under load.\u003c\/p\u003e\n\u003ch3\u003eCLASS AB AMPLIFICATION\u003c\/h3\u003e\n\u003cp\u003eThe amplifier uses a traditional Class AB topology, optimized for low crossover distortion and high linear power delivery. This design combines high efficiency with the tonal stability and control expected in high-end stereo systems.\u003c\/p\u003e\n\u003cp\u003eThe measured frequency response extends from 10 Hz to 100 kHz with a ±0.5 dB tolerance, ensuring linear reproduction across the entire audible spectrum.\u003c\/p\u003e\n\u003ch3\u003eTRUE DUAL MONO DESIGN\u003c\/h3\u003e\n\u003cp\u003eThe signal path is built in a dual monoblock architecture, where each channel has its own power supply section and signal structure. This reduces crosstalk between channels and improves stereo separation.\u003c\/p\u003e\n\u003cp\u003eThe result is a more stable stereo image and better spatial definition in complex recordings.\u003c\/p\u003e\n\u003ch3\u003eCONNECTIONS AND SYSTEM INTEGRATION\u003c\/h3\u003e\n\u003cp\u003eThe RB-1590 offers both balanced XLR inputs and traditional RCA inputs, making it compatible with both high-end preamplifiers and integrated solutions.\u003c\/p\u003e\n\u003cp\u003eTwo sets of heavy-duty 5-way speaker terminals allow for bi-wiring or connection of multiple speakers. 12V trigger makes integration into larger systems simple and automated.\u003c\/p\u003e\n\u003ch3\u003ePROTECTION AND OPERATIONAL RELIABILITY\u003c\/h3\u003e\n\u003cp\u003eThe amplifier is equipped with comprehensive protection circuits against overcurrent, overheating, and overvoltage. A two-stage startup sequence reduces inrush current and protects the components from unnecessary wear.\u003c\/p\u003e\n\u003cp\u003eThe design is housed in a massive 5U chassis with high mechanical stability and efficient heat dissipation.\u003c\/p\u003e\n\u003ch3\u003ePOSITIONING\u003c\/h3\u003e\n\u003cp\u003eThe RB-1590 is developed for high-end stereo systems where high power reserve, stable current delivery, and low distortion are necessary to drive modern speaker designs optimally.\u003c\/p\u003e\n\u003cp\u003eA reference stereo power amplifier designed for large listening rooms, demanding speakers, and systems with a clear focus on dynamics, control, and signal integrity.\u003c\/p\u003e","brand":"Rotel","offers":[{"title":"Silver","offer_id":55501250101624,"sku":"85207","price":3576.95,"currency_code":"EUR","in_stock":true},{"title":"Black","offer_id":55501250134392,"sku":"55501248790905","price":3576.95,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0819\/6253\/3137\/files\/rb1590_silver_0_2500x2500_47d85c2f-a9ae-4ad7-84aa-77963740e4b2.jpg?v=1773615640","url":"https:\/\/www.lydspecialisten.eu\/products\/rotel-rb-1590","provider":" Lydspecialisten","version":"1.0","type":"link"}
