Class-D circuit architecture efficiently converts power into impactful audio output while keeping heat generation and power consumption low, and custom cool guide technology ensures consistent and reliable operation even at sustained high output levels. A built-in limiter circuit engages automatically at peak output to prevent speaker overload, providing an important layer of protection for connected cabinets during demanding use.\u003c\/p\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal\" dir=\"ltr\"\u003eSwitchable stereo, parallel mono and bridge mono modes provide flexible configuration options to suit different system requirements — with bridge mode delivering 300W into 8 Ohms for high-power mono applications such as subwoofer amplification. Three switchable input sensitivity settings (0.775V, 1.0V and 1.44V) ensure compatibility with a wide range of source equipment, and a switchable 75Hz low-cut filter helps manage low-frequency content for cleaner, more focused output. XLR female inputs with XLR male thru outputs allow straightforward signal routing and daisy-chaining within the rig, and L+R SPK connectors provide versatile speaker output connectivity.\u003c\/p\u003e\n\u003ch6 class=\"font-claude-response-body break-words whitespace-normal\" dir=\"ltr\"\u003eClass-D Efficiency \u0026amp; Cool Guide Technology\u003c\/h6\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal\" dir=\"ltr\"\u003eThe Class-D circuit architecture of the D300 efficiently converts mains power into audio output, minimising wasted energy as heat and allowing the amplifier to operate reliably even at sustained high output levels without the thermal management challenges associated with traditional Class-AB designs. Citronic's custom cool guide technology further supports consistent and reliable operation over extended periods, making the D300 well suited to installation and touring environments where the amplifier may be driven hard for long durations.\u003c\/p\u003e\n\u003ch6 class=\"font-claude-response-body break-words whitespace-normal\" dir=\"ltr\"\u003eFlexible Modes \u0026amp; Built-In Protection\u003c\/h6\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal\" dir=\"ltr\"\u003eSwitchable stereo, parallel mono and bridge mono modes allow the D300 to be configured to suit a wide range of system architectures and requirements. In bridge mode it delivers 300W into 8 Ohms, making it a useful high-power mono option for subwoofer driving or mono PA configurations. The built-in limiter circuit provides an important safeguard, engaging automatically at peak output to prevent speaker overload and protect connected cabinets from damage during demanding performances.\u003c\/p\u003e\n\u003ch6 class=\"font-claude-response-body break-words whitespace-normal\" dir=\"ltr\"\u003eSwitchable Sensitivity, Low-Cut Filter \u0026amp; Versatile Connectivity\u003c\/h6\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal\" dir=\"ltr\"\u003eThree switchable input sensitivity settings — 0.775V, 1.0V and 1.44V — ensure broad compatibility with a wide range of professional mixers and source equipment, and a switchable 75Hz low-cut filter helps clean up low-frequency content for tighter, more focused sound reinforcement. XLR female inputs with XLR male thru outputs allow the signal to be passed to additional amplifiers or equipment within the rig, and L+R SPK connectors provide straightforward speaker connectivity across all operating modes.\u003c\/p\u003e\n\u003ch5\u003eKEY FEATURES: Citronic D300 Power Amplifier\u003c\/h5\u003e\n\u003cul\u003e\n\u003cli class=\"font-claude-response-body whitespace-normal break-words pl-2\"\u003e\n\u003cstrong\u003eClass-D Power Amplifier:\u003c\/strong\u003e Efficient Class-D architecture delivers 2 x 150W RMS at 4 Ohms with minimal heat generation for reliable sustained operation.\u003c\/li\u003e\n\u003cli class=\"font-claude-response-body whitespace-normal break-words pl-2\"\u003e\n\u003cstrong\u003eCustom Cool Guide Technology:\u003c\/strong\u003e Ensures consistent and reliable thermal management even at high output levels over extended periods.\u003c\/li\u003e\n\u003cli class=\"font-claude-response-body whitespace-normal break-words pl-2\"\u003e\n\u003cstrong\u003eBuilt-In Limiter:\u003c\/strong\u003e Automatically engages at peak output to prevent speaker overload and protect connected cabinets.\u003c\/li\u003e\n\u003cli class=\"font-claude-response-body whitespace-normal break-words pl-2\"\u003e\n\u003cstrong\u003eStereo, Parallel \u0026amp; Bridge Modes:\u003c\/strong\u003e Flexible configuration options including 300W bridged mono at 8 Ohms for high-power single-channel applications.\u003c\/li\u003e\n\u003cli class=\"font-claude-response-body whitespace-normal break-words pl-2\"\u003e\n\u003cstrong\u003eSwitchable Input Sensitivity:\u003c\/strong\u003e Three settings — 0.775V, 1.0V and 1.44V — for broad compatibility with professional source equipment.\u003c\/li\u003e\n\u003cli class=\"font-claude-response-body whitespace-normal break-words pl-2\"\u003e\n\u003cstrong\u003eSwitchable 75Hz Low-Cut Filter:\u003c\/strong\u003e Reduces unwanted low-frequency content for tighter, more focused sound reinforcement output.\u003c\/li\u003e\n\u003cli class=\"font-claude-response-body whitespace-normal break-words pl-2\"\u003e\n\u003cstrong\u003eXLR Inputs With Thru Outputs:\u003c\/strong\u003e L+R XLR female inputs and L+R XLR male thru outputs for straightforward signal routing and daisy-chaining.\u003c\/li\u003e\n\u003cli class=\"font-claude-response-body whitespace-normal break-words pl-2\"\u003e\n\u003cstrong\u003eSPK Speaker Outputs:\u003c\/strong\u003e L+R SPK connectors for versatile speaker cabinet connectivity across all operating modes.\u003c\/li\u003e\n\u003cli class=\"font-claude-response-body whitespace-normal break-words pl-2\"\u003e\n\u003cstrong\u003eCompact 1U Rack Format:\u003c\/strong\u003e Lightweight at just 3.5kg and occupying only 1U of rack space for efficient installation in any standard rack.\u003cbr\u003e\n\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Citronic","offers":[{"title":"Default Title","offer_id":58375760740687,"sku":"172.103","price":198.0,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0891\/3344\/9551\/files\/172103UK_CO1.jpg?v=1785774629","url":"https:\/\/www.audiodirect.co.uk\/products\/citronic-d300-class-d-power-amplifier","provider":"Audio Direct","version":"1.0","type":"link"}
