It delivers 15 watts RMS per channel to speaker loads and 105 milliwatts RMS per channel to headphone outputs, making it suitable for both background music distribution and localized listening points. The unit runs on 12 volts DC at up to 9 amps and is housed in a black metal enclosure. It includes an onboard speaker protection circuit to safeguard connected loads during startup and fault conditions. Licensed audio installers and low-voltage technicians are the typical trade installing this type of equipment.\u003c\/p\u003e\n\u003cp\u003eThe lb-4z100 is well suited to light commercial and residential multi-zone audio applications where a single audio source must be distributed across multiple areas simultaneously. Typical install scenarios include restaurants, retail spaces, offices, and residential whole-home audio systems where zone-level volume control is required. The 4-zone configuration allows independent speaker runs without the need for an external zone controller when source switching is not required.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eClass-D amplifier topology for efficient low-heat operation at 12 volts DC\u003c\/li\u003e\n  \u003cli\u003e15W RMS per channel speaker output across 4 zones\u003c\/li\u003e\n  \u003cli\u003e105 mW RMS per channel headphone output per zone\u003c\/li\u003e\n  \u003cli\u003eMinimum speaker load resistance of 4 ohms per channel\u003c\/li\u003e\n  \u003cli\u003eMinimum headphone load resistance of 16 ohms\u003c\/li\u003e\n  \u003cli\u003eOnboard speaker protection circuit prevents output damage at power-on and during fault events\u003c\/li\u003e\n  \u003cli\u003eBlack metal housing for rack or surface mounting in professional installs\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style distributed audio amplifier for 1-source, 4-zone stereo speaker systems using 4-ohm or higher impedance speaker loads.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation should be performed by a qualified low-voltage technician or licensed audio systems installer. Disconnect the 12-volt DC power supply before making any speaker or input wiring connections. Verify that speaker loads meet the 4-ohm minimum impedance requirement before powering the unit to avoid triggering the protection circuit. Local codes governing low-voltage wiring, such as NEC Article 725, may apply depending on jurisdiction.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eAmplifier Type\u003c\/strong\u003e: Stereo Class-D\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOutput Power (Speaker)\u003c\/strong\u003e: 15W RMS per channel\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOutput Power (Headphone)\u003c\/strong\u003e: 105 mW RMS per channel\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eZones\u003c\/strong\u003e: 4\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSources\u003c\/strong\u003e: 1\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMinimum Speaker Load Resistance\u003c\/strong\u003e: 4 ohms\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMinimum Headphone Load Resistance\u003c\/strong\u003e: 16 ohms\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePower Requirement\u003c\/strong\u003e: 12 volts DC, 9A max\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHousing Material\u003c\/strong\u003e: Black metal\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSpeaker Protection Circuit\u003c\/strong\u003e: Included\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eStandard Information\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: LIONBEAM\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: lb-4z100\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"LIONBEAM","offers":[{"title":"Default Title","offer_id":51525421728050,"sku":"LB-4Z100","price":170.5,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/0abf4e26c4ce92b68d941c40f4930962.jpg?v=1785473314","url":"https:\/\/voomisupply.com\/products\/lionbeam-lb-4z100-stereo-class-d-amplifier-1-source-4-zone","provider":"Voomi Supply","version":"1.0","type":"link"}
