Sharing the same comprehensive priority routing system, emergency input, paging capability and intuitive front panel design as the MA60, the MA120 delivers the same ease of use and professional feature set at double the output power — making it the ideal choice for larger retail, hospitality, education, corporate and public venue environments where greater coverage area or higher output levels are required from a single-channel mixing amplifier.\u003c\/p\u003e\n\u003cp dir=\"ltr\"\u003e\u003cstrong\u003eFour Priority Levels \u0026amp; Expanded Input Configuration\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp dir=\"ltr\"\u003eThe MA120 provides four priority levels for audio routing — a dedicated emergency input for life safety and building system integration, a paging input with contact closure and chime for announcement and paging applications, two balanced mic\/line inputs with 48V phantom power for microphone and line-level sources, and four stereo line inputs summed to mono for background music players and other stereo source devices. The expanded input count over the MA60 — with two phantom-powered mic inputs and four stereo line inputs — provides comprehensive source connectivity for more complex installation scenarios where multiple microphones and music sources need to be managed from a single amplifier. A 24V priority output overrides local volume controls when activated, and a mute all switch on the emergency input provides immediate system muting in emergency situations. A VOX mute function automatically reduces background music when a microphone signal is detected.\u003c\/p\u003e\n\u003cp dir=\"ltr\"\u003e\u003cstrong\u003e120W Class D Efficiency \u0026amp; Fanless Operation\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp dir=\"ltr\"\u003eThe MA120's Class D amplifier topology delivers efficient, reliable 120W output from a compact 2U rack-mount enclosure without the need for a cooling fan — ensuring completely silent operation for noise-sensitive installation environments. An internal universal power supply (100–240V AC) enables straightforward installation in any mains environment, and an auto standby mode reduces power consumption when the system is not in use.\u003c\/p\u003e\n\u003ch3 dir=\"ltr\"\u003eBiamp MA120 Key Features:\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003e120W Class D Single-Channel Amplifier:\u003c\/strong\u003e Continuous 120W output at both 100V line and 4 Ohm low-impedance for larger speaker system installations.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFour Priority Levels:\u003c\/strong\u003e Emergency input, paging input, two mic\/line inputs and four stereo line inputs with hierarchical audio routing.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDedicated Emergency Input with Mute All Switch:\u003c\/strong\u003e Immediate system muting and emergency message override for life safety integration.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePaging Input with Contact Closure \u0026amp; Chime:\u003c\/strong\u003e Attention-grabbing chime and priority paging capability for announcement applications.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003e2 x Balanced Mic\/Line Inputs with 48V Phantom Power:\u003c\/strong\u003e Dual phantom-powered inputs for flexible microphone and line-level source connectivity.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003e4 x Stereo Line Inputs (Mono Summed):\u003c\/strong\u003e For background music players and multiple stereo source devices.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003e24V Priority Output:\u003c\/strong\u003e Overrides local volume controls for consistent paging and emergency message levels.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eVOX Mute:\u003c\/strong\u003e Automatically reduces background music when a microphone signal is detected.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTone Control:\u003c\/strong\u003e Adjustable tonal shaping for the output signal.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003e100V Line \u0026amp; 4 Ohm Operation:\u003c\/strong\u003e Compatible with both distributed 100V and direct low-impedance speaker systems.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFanless Convection Cooling:\u003c\/strong\u003e Silent operation for noise-sensitive installation environments.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eAuto Standby Mode:\u003c\/strong\u003e Reduces power consumption when the system is not in active use.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInternal Universal Power Supply:\u003c\/strong\u003e 100–240V AC for straightforward installation in any mains environment.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003e2U 19\" Rack Mountable:\u003c\/strong\u003e Standard rack installation for professional commercial audio systems.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003e5-Year Biamp Warranty:\u003c\/strong\u003e Backed by Biamp Systems' comprehensive manufacturer warranty.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCE Marked, UL Listed \u0026amp; RoHS Compliant:\u003c\/strong\u003e Meets professional installation regulatory requirements.\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Biamp","offers":[{"title":"Default Title","offer_id":57555688292725,"sku":"BIAMA120","price":389.0,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/2083\/7259\/files\/APAMA120_Apart_913-0659-900_Image_1.webp?v=1788796057","url":"https:\/\/www.audiovolt.co.uk\/products\/biamp-ma120-120w-rack-mount-mixer-amplifier-100v-4ohm","provider":"Audio Volt ","version":"1.0","type":"link"}
