Part of Dolby's DSR immersive surround series, it is typically used for overhead positions in Dolby Atmos rooms. Its patented asymmetrical waveguide covers 80° at the top and 130° at the bottom horizontally, with 80° vertical, for wide and even overhead coverage.\u003c\/p\u003e\n\n\u003ch2\u003eHow does the Dolby DSR1280 work?\u003c\/h2\u003e\n\u003cp\u003eOverhead channels need full-bandwidth speakers that cover a broad area of seats from above. The DSR1280 combines a custom high-sensitivity 12-inch low-frequency driver with a low-distortion 44.4 mm high-frequency driver on a baffle-mounted asymmetrical waveguide. The wider 80°\/130° pattern spreads energy over more rows than the side-surround DSR1260 while keeping volume linear and targeted.\u003c\/p\u003e\n\u003cp\u003eThe cabinet mounts vertically or horizontally to stay clear of the projector light path, and the high-frequency horn rotates within the enclosure to keep coverage on the most seats. A passive crossover and top-of-cabinet input plate with a high-current terminal allow plug-and-play operation from one amplifier channel. It is rated at 525 W @ 64.8 Vrms into 8 ohms with 127 dB continuous half-space SPL at one metre and a target throw distance of 19 metres.\u003c\/p\u003e\n\u003cp\u003eOverhead feeds come from a \u003ca href=\"https:\/\/creationnetworks.net\/products\/dolby-atmos-cinema-processor-cp950a\"\u003eDolby CP950A Atmos processor\u003c\/a\u003e, and a Dolby Multichannel Amplifier such as the \u003ca href=\"https:\/\/creationnetworks.net\/products\/dolby-professional-32-channels-dma32301-multichannel-amplifier\"\u003eDMA32301\u003c\/a\u003e drives the array.\u003c\/p\u003e\n\n\u003ch2\u003eWhat are the key features of the Dolby DSR1280?\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eWide asymmetrical waveguide\u003c\/strong\u003e — 80° top \/ 130° bottom horizontal and 80° vertical coverage suits overhead arrays.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eRotatable HF horn\u003c\/strong\u003e — the horn rotates so the cabinet can be mounted in either orientation.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003e12-inch high-sensitivity woofer\u003c\/strong\u003e — full-bandwidth surround reproduction from 55 Hz to 20 kHz.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLow-distortion HF driver\u003c\/strong\u003e — a 44.4 mm polyimide dome driver gives smooth, detailed highs.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePassive crossover\u003c\/strong\u003e — plug-and-play operation from a single amplifier channel.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLow-reflection Dolby design\u003c\/strong\u003e — the finish minimizes reflection of projection light.\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch2\u003eWhere is the Dolby DSR1280 typically used?\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003eDolby Atmos cinema auditorium (medium to large)\u003c\/li\u003e\n\u003cli\u003ePremium large-format auditorium\u003c\/li\u003e\n\u003cli\u003eScreening room\u003c\/li\u003e\n\u003cli\u003eAuditorium\u003c\/li\u003e\n\u003cli\u003eHouse of worship\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch2\u003eTechnical Specifications\u003c\/h2\u003e\n\u003cdiv style=\"overflow-x:auto;\"\u003e\n\u003ctable style=\"width:100%;max-width:640px;min-width:300px;table-layout:fixed;border-collapse:collapse;\"\u003e\n\u003ccolgroup\u003e\n\u003ccol style=\"width:38%\"\u003e\n\u003ccol style=\"width:62%\"\u003e\n\u003c\/colgroup\u003e\n\u003ctbody\u003e\n\u003ctr\u003e\n\u003ctd style=\"padding:6px;border:1px solid #ddd;\"\u003e\u003cstrong\u003eModel\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd style=\"padding:6px;border:1px solid #ddd;\"\u003eDSR1280\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd style=\"padding:6px;border:1px solid #ddd;\"\u003e\u003cstrong\u003eFrequency range\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd style=\"padding:6px;border:1px solid #ddd;\"\u003e55 Hz -
