Delivering 120W of output power in a compact half-rack 1U enclosure, the U120:1M is ideal for background music and voice announcement applications across bars, restaurants, retail outlets, educational institutions, houses of worship, museums, galleries, transport hubs and conference centres.\u003c\/p\u003e\n\u003cp dir=\"ltr\"\u003eIncluded brackets facilitate single and dual rack-mount configurations alongside desktop and under-counter installations. When rack-mounted side by side, two U120:1M units occupy a single rack unit — effectively doubling both channel count and output power within the same rack space.\u003c\/p\u003e\n\u003cp dir=\"ltr\"\u003e\u003cstrong\u003eVersatile 4-Input Configuration\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp dir=\"ltr\"\u003eThe U120:1M provides four input channels covering a wide range of source types. Inputs 1 and 2 are balanced mic\/line inputs with switchable 48V phantom power — Input 1 features contact override with 2-tone chime for attention-grabbing paging alerts, whilst Input 2 includes VOX ducking that automatically reduces background music volume when a voice signal is detected, ensuring clear voice communication without manual intervention. Inputs 3 and 4 are unbalanced stereo RCA line inputs for media players and other consumer audio sources, converted to mono internally. 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.\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 U120:1M 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, more focused 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 U120:1M 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. Unlike the U30:1M and U60:1M, the U120:1M features a four-stage variable-speed fan cooling system — automatically adjusting fan speed between off, slow, medium and fast in response to thermal load — ensuring reliable thermal management at the higher power output levels of the 120W amplifier stage.\u003c\/p\u003e\n\u003ch3 dir=\"ltr\"\u003eDynacord U120:1M Key Features:\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003e120W Class D Amplifier:\u003c\/strong\u003e The highest-powered model in the U:1M half-rack series for larger commercial installations.\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\u003e4 Inputs:\u003c\/strong\u003e 2 x balanced mic\/line with phantom power, 2 x unbalanced stereo RCA line inputs.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSwitchable 48V Phantom Power:\u003c\/strong\u003e Per mic\/line input for condenser microphone use.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eVOX Ducking (Input 2):\u003c\/strong\u003e Automatically reduces background music volume when a voice signal is detected.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eContact Override with 2-Tone Chime (Input 1):\u003c\/strong\u003e Attention-grabbing chime and priority override for paging applications.\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\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 at higher power levels.\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":57530252099957,"sku":"DYNU1201M","price":379.0,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/2083\/7259\/files\/DYNU1201M_Dynacord_F-01U-425-748_Image_1.webp?v=1787909502","url":"https:\/\/www.audiovolt.co.uk\/products\/dynacord-u1201m-mixer-amplifier","provider":"Audio Volt ","version":"1.0","type":"link"}
