Unlike the U:1M mixer amplifier models in the Dynacord U series, the U120:1 is a dedicated power amplifier with a single line input — making it the ideal choice for installations where mixing and source selection is handled upstream by a separate mixer or zone controller, and a reliable, compact and space-efficient power amplifier is needed to drive the speaker system.\u003c\/p\u003e\n\u003cp dir=\"ltr\"\u003eDelivering 120W of output power in a half-rack 1U enclosure, the U120:1 is suitable for background music and voice announcement applications across bars, restaurants, retail outlets, educational institutions, houses of worship, museums, galleries, transport hubs and conference centres. Included brackets facilitate single and dual rack-mount configurations alongside desktop and under-counter installations, and when rack-mounted side by side, two U120:1 units occupy a single rack unit — effectively doubling channel count and output power within the same rack space.\u003c\/p\u003e\n\u003cp dir=\"ltr\"\u003e\u003cstrong\u003eSingle Line Input with EMG Override\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp dir=\"ltr\"\u003eThe U120:1 accepts a single line-level input via unbalanced stereo RCA (mono summed) or a balanced 3-pin Eurostyle connector, with a sensitivity of 100mV and an input impedance of 4.6kΩ. A dedicated EMG input accepts both line-level and 100V signals for emergency message override — ensuring critical announcements are always heard clearly above all other audio sources, with a DIP-switch selectable EMG input mode for HiZ or line-level signal compatibility. A contact override with 2-tone chime provides an additional attention-grabbing paging alert capability.\u003c\/p\u003e\n\u003cp dir=\"ltr\"\u003e\u003cstrong\u003eFull Impedance Flexibility \u0026amp; DSP\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp dir=\"ltr\"\u003eThe U120:1 supports 4Ω, 8Ω, 70V and 100V speaker operation — selectable via DIP switch — for complete compatibility with both low-impedance and distributed 100V speaker systems. Bass and treble shelving EQ of ±12dB provides tonal shaping of the output signal, and two high-pass filters — a permanently active 20Hz filter and a switchable 120Hz filter — allow unwanted low-frequency content to be removed from the signal path for cleaner audio reproduction through installed speakers.\u003c\/p\u003e\n\u003cp dir=\"ltr\"\u003e\u003cstrong\u003eComprehensive Protection, Status Monitoring \u0026amp; Fan Cooling\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp dir=\"ltr\"\u003eThe U120:1 incorporates a comprehensive protection suite including audio limiters, high temperature, DC, HF, short circuit and over-current protection on the amplifier, alongside mains over\/under voltage protection, inrush current limiting, mains over-current and high-temperature protection on the switching mode power supply. Front-panel status LEDs provide clear at-a-glance indication of power, signal, peak, call and protection status, and a remote power OFF contact closure input enables remote standby activation for energy-efficient operation. A four-stage variable-speed fan cooling system automatically adjusts fan speed between off, slow, medium and fast in response to thermal load for reliable thermal management.\u003c\/p\u003e\n\u003ch3 dir=\"ltr\"\u003eDynacord U120:1 Key Features:\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003e120W Class D Power Amplifier:\u003c\/strong\u003e Compact half-rack amplification for commercial installations where mixing is handled upstream.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHalf-Rack 1U Enclosure:\u003c\/strong\u003e Two units mount side by side in a single rack unit — doubling channel count and output power within the same rack space.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSingle Line Input:\u003c\/strong\u003e Unbalanced RCA (mono summed) or balanced 3-pin Eurostyle for straightforward integration with any upstream mixer or zone controller.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eEMG Override Input:\u003c\/strong\u003e Line and 100V emergency message input — ensures critical announcements are always heard.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eContact Override with 2-Tone Chime:\u003c\/strong\u003e Attention-grabbing chime and priority override for paging applications.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003e4Ω, 8Ω, 70V \u0026amp; 100V Speaker Operation:\u003c\/strong\u003e DIP switch selectable for full low-impedance and distributed system compatibility.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBass \u0026amp; Treble Shelving EQ:\u003c\/strong\u003e ±12dB at 150Hz and 5kHz for tonal shaping of the output signal.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003e20Hz (Permanent) \u0026amp; 120Hz (Switchable) High-Pass Filters:\u003c\/strong\u003e Remove unwanted low-frequency content from the signal path.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFour-Stage Variable-Speed Fan Cooling:\u003c\/strong\u003e Automatically adjusts between off, slow, medium and fast for reliable thermal management.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eRemote Power OFF:\u003c\/strong\u003e Contact closure input for remote standby activation and energy efficiency.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFront-Panel Status LEDs:\u003c\/strong\u003e Power, signal, peak, call and protection status indication.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eComprehensive Protection:\u003c\/strong\u003e Audio limiters, thermal, DC, HF, short circuit, over-current and mains protection.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlexible Mounting:\u003c\/strong\u003e 19\" rack, half-rack, desktop, under-counter and side-by-side dual configurations.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOperating Temperature -5°C to +45°C:\u003c\/strong\u003e Suitable for a wide range of commercial installation environments.\u003cbr\u003e\n\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Dynacord","offers":[{"title":"Default Title","offer_id":57530278838645,"sku":"DYNU1201","price":347.0,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/2083\/7259\/files\/DYNU1201_Dynacord_F-01U-425-740_Image_1.webp?v=1787910638","url":"https:\/\/www.audiovolt.co.uk\/products\/dynacord-u1201-power-amplifier","provider":"Audio Volt ","version":"1.0","type":"link"}
