Capable of switching up to four speaker loads from a primary amplifier to a backup, this unit ensures uninterrupted audio delivery during amplifier failure. It operates in two modes—stand-alone via logic inputs or network-controlled through the GLOBALCOM® supervision sub-system.\u003c\/p\u003e \u003cp\u003eEach of the four channels can be individually managed, and in network mode, multiple 1544BAS units can route multiple primary amplifiers to a shared backup. Power is delivered via IEEE 802.3af PoE or an optional +48VDC supply. Channel and power status LEDs provide instant visual diagnostics, and the rugged housing supports DIN-rail or panel mounting near amplifier racks for efficient deployment.\u003c\/p\u003e \u003ch3\u003eKey Features\u003c\/h3\u003e \u003cul\u003e \u003cli\u003e \u003cstrong\u003e4-Channel Switching:\u003c\/strong\u003e Transfers speaker loads from primary to backup amplifier\u003c\/li\u003e \u003cli\u003e \u003cstrong\u003eDual Operation Modes:\u003c\/strong\u003e Stand-alone logic or GLOBALCOM® network supervision\u003c\/li\u003e \u003cli\u003e \u003cstrong\u003ePoE Powered:\u003c\/strong\u003e Supports IEEE 802.3af or external 48VDC power\u003c\/li\u003e \u003cli\u003e \u003cstrong\u003eStatus LEDs:\u003c\/strong\u003e Clear indicators for power and backup channel activation\u003c\/li\u003e \u003cli\u003e \u003cstrong\u003eCompact Installation:\u003c\/strong\u003e Mounts to DIN rail or panel near amplifiers\u003c\/li\u003e \u003c\/ul\u003e \u003ch3\u003eTechnical Specifications\u003c\/h3\u003e \u003cul\u003e \u003cli\u003e \u003cstrong\u003eDimensions:\u003c\/strong\u003e 7.01 × 3.50 × 2.00 inches (178 × 89 × 51 mm)\u003c\/li\u003e \u003cli\u003e \u003cstrong\u003eWeight:\u003c\/strong\u003e 9.6 oz (272 g)\u003c\/li\u003e \u003cli\u003e \u003cstrong\u003eInput Voltage:\u003c\/strong\u003e 48 VDC (PoE Compliant)\u003c\/li\u003e \u003cli\u003e \u003cstrong\u003ePower Consumption:\u003c\/strong\u003e Max 4 Watts\u003c\/li\u003e \u003cli\u003e \u003cstrong\u003eMax Switching Current:\u003c\/strong\u003e 8 Amps\u003c\/li\u003e \u003cli\u003e \u003cstrong\u003eOperating Temperature:\u003c\/strong\u003e –22°F to +149°F (–30°C to +65°C)\u003c\/li\u003e \u003c\/ul\u003e \u003c\/div\u003e","brand":"ToneCraft Gear","offers":[{"title":"Default Title","offer_id":68181652144432,"sku":"ATS-IED1544BAS","price":974.24,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/1004\/3067\/6272\/files\/1-atlasied-ied1544bas_8153a591-04b1-4f3b-b6ed-33ea8ee93f41.jpg?v=1793016914","url":"https:\/\/tonecraftgear.shop\/products\/atlasied-1544bas-four-channel-backup-amplifier-switch","provider":"ToneCraft Gear","version":"1.0","type":"link"}
