It delivers 45 watts per channel and supports bridged operation, allowing paired channels to combine for up to 180 watts of output when driving a single zone at higher power. The d890 includes selectable high-pass, low-pass, and full-range filter settings on each channel, giving installers precise control over speaker frequency response without external crossovers. Licensed audio-visual or low-voltage contractors are the typical installers for this class of equipment.\u003c\/p\u003e\u003cp\u003eThe d890 supports four independent playback zones, making it well suited for whole-home audio systems where separate rooms or areas require individual source and volume control. Typical applications include background music distribution in homes, offices, retail spaces, and hospitality environments. Each zone operates independently, so audio in one room can be adjusted or muted without affecting the others. The amplifier is sized for rack-mount or equipment-closet installation, keeping the signal path centralized while speakers are distributed throughout the structure.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e8 amplifier channels rated at 45 watts per channel\u003c\/li\u003e\n\u003cli\u003eBridgeable channel pairs for up to 180 watts per zone\u003c\/li\u003e\n\u003cli\u003e4 independent playback zones for simultaneous multi-room audio\u003c\/li\u003e\n\u003cli\u003eSelectable high-pass, low-pass, and full-range filter settings per channel\u003c\/li\u003e\n\u003cli\u003eCentralized installation suitable for rack-mount or equipment-closet setups\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style distributed audio amplifier for multi-zone residential and light commercial audio systems.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation should be performed by a licensed low-voltage or audio-visual contractor familiar with distributed audio wiring practices. Power down the amplifier and disconnect all source and speaker connections before servicing or reconfiguring channel assignments. Follow local building codes and NEC guidelines for in-wall speaker wiring and equipment-room installations. Do not bridge channels beyond the rated configuration or connect loads below the minimum impedance specified in the manufacturer documentation.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eNumber of Channels\u003c\/strong\u003e: 8\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePower Output\u003c\/strong\u003e: 45 watts per channel\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBridged Power Output\u003c\/strong\u003e: 180 watts per channel pair\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePlayback Zones\u003c\/strong\u003e: 4 independent zones\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFilter Settings\u003c\/strong\u003e: High-pass, low-pass, full-range\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: RUSSOUND\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: d890\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"RUSSOUND","offers":[{"title":"Default Title","offer_id":51525286658354,"sku":"D890","price":826.6,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/a1e1b1d461362812c457c74fb7f85153.jpg?v=1785469585","url":"https:\/\/voomisupply.com\/products\/russound-d890-8-channel-multi-room-power-amplifier","provider":"Voomi Supply","version":"1.0","type":"link"}
