For installers and system designers who need greater amplifier headroom to drive larger speaker arrays or cover bigger spaces, but cannot compromise on rack space or installation footprint, the UA240 represents an outstanding solution. Whether installed below a counter, under a desk, in a half-rack enclosure or alongside a second UA240 in a standard 19\" rack using the supplied mounting hardware, the UA240 delivers high-power mixer amplifier performance in a form factor that few competitors can match.\u003c\/p\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal leading-[1.7]\"\u003e\u003cstrong\u003eVersatile Inputs for Any Source\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal leading-[1.7]\"\u003eThe UA240 features the same well-specified 5-channel input mixer as its smaller sibling, accommodating a wide variety of source connections in a single compact unit. Three switchable mic\/line inputs — one via a combo XLR\/jack and two via 6.3mm jack — handle microphones and line-level sources with individual front panel volume controls for precise level management across each channel. An RCA line input and a 3.5mm aux input provide flexible connectivity for background music sources, streaming devices and other consumer audio equipment. A global 2-band EQ allows tonal adjustment of the overall output to suit the acoustic environment, whilst a master output control governs the overall system level.\u003c\/p\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal leading-[1.7]\"\u003e\u003cstrong\u003e100V Line \u0026amp; Low Impedance Operation\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal leading-[1.7]\"\u003eThe UA240 supports both 100V line and 2 Ohm low impedance speaker operation via Euroblock screw terminals on the rear panel. The step up to 240W makes the UA240 particularly well suited to larger distributed 100V line installations with higher speaker counts, or to more demanding low impedance setups where greater power headroom is required to fill larger spaces with confidence. The dual-mode output flexibility ensures the UA240 can be specified across a broad range of installation types and system configurations without compromise.\u003c\/p\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal leading-[1.7]\"\u003e\u003cstrong\u003eProfessional Installation Features\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal leading-[1.7]\"\u003eThe UA240 carries the same professional installation feature set as the rest of the UA series. Switchable +20V phantom power on channel 1 — available via XLR or rear terminals — accommodates condenser microphones and desktop paging microphones without requiring a separate power supply. A 24V fire alarm mute contact enables integration with a building's fire alarm system for automatic audio muting in an emergency, whilst two RCA mono line outputs on the rear panel allow the signal to be looped through to additional amplifiers or zones. The Class D amplifier with transformer output ensures efficient, cool-running operation even at the UA240's higher continuous power output.\u003c\/p\u003e\n\u003ch3 class=\"font-claude-response-body break-words whitespace-normal leading-[1.7]\"\u003eAdastra UA240 Key Features:\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli class=\"whitespace-normal break-words pl-2\"\u003e\n\u003cstrong\u003e240W RMS Class D Amplifier:\u003c\/strong\u003e High-power Class D amplification with transformer output delivering serious headroom for larger spaces and higher speaker counts.\u003c\/li\u003e\n\u003cli class=\"whitespace-normal break-words pl-2\"\u003e\n\u003cstrong\u003eHalf-Rack 1U Compact Chassis:\u003c\/strong\u003e The same minimal footprint as the UA120, ideal for under-counter, under-desk, half-rack or dual rack-mount installations where space is at a premium.\u003c\/li\u003e\n\u003cli class=\"whitespace-normal break-words pl-2\"\u003e\n\u003cstrong\u003e5-Channel Input Mixer:\u003c\/strong\u003e 3 x switchable mic\/line inputs (combo XLR + 2 x 6.3mm), 1 x RCA line input and 1 x 3.5mm aux input with individual channel volume controls.\u003c\/li\u003e\n\u003cli class=\"whitespace-normal break-words pl-2\"\u003e\n\u003cstrong\u003e100V Line \u0026amp; 2 Ohm Operation:\u003c\/strong\u003e Switchable between 100V line and 2 Ohm low impedance speaker outputs via rear Euroblock terminals for maximum system compatibility.\u003c\/li\u003e\n\u003cli class=\"whitespace-normal break-words pl-2\"\u003e\n\u003cstrong\u003eGlobal 2-Band EQ:\u003c\/strong\u003e Overall tonal control to suit different room acoustics and installation environments.\u003c\/li\u003e\n\u003cli class=\"whitespace-normal break-words pl-2\"\u003e\n\u003cstrong\u003e+20V Phantom Power on CH1:\u003c\/strong\u003e Switchable phantom power via XLR or rear terminals for condenser microphones and desktop paging microphones.\u003c\/li\u003e\n\u003cli class=\"whitespace-normal break-words pl-2\"\u003e\n\u003cstrong\u003e24V Fire Alarm Mute Contacts:\u003c\/strong\u003e Relay mute contacts for integration with building fire alarm systems for automatic audio muting in an emergency.\u003c\/li\u003e\n\u003cli class=\"whitespace-normal break-words pl-2\"\u003e\n\u003cstrong\u003e2 x RCA Mono Line Outputs:\u003c\/strong\u003e Loop-through outputs for connection to additional amplifiers or zones.\u003c\/li\u003e\n\u003cli class=\"whitespace-normal break-words pl-2\"\u003e\n\u003cstrong\u003eSupplied with Rack-Mount Hardware:\u003c\/strong\u003e Includes hardware for rack-mounting two UA240 units side by side in a standard 19\" rack enclosure, or for single unit wall or worktop mounting.\u003c\/li\u003e\n\u003cli class=\"whitespace-normal break-words pl-2\"\u003e\n\u003cstrong\u003eRemovable Euroblock Speaker Connector:\u003c\/strong\u003e Rear panel Euroblock terminals for clean, secure and professional speaker wiring.\u003cbr\u003e\n\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Adastra","offers":[{"title":"Default Title","offer_id":56990545478005,"sku":"953.013","price":229.0,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/2083\/7259\/files\/953013UK_CO1_00c64f4c-bbf9-4d17-b268-a8f9e9cbabd5.jpg?v=1774347569","url":"https:\/\/www.audiovolt.co.uk\/products\/adastra-ua240-compact-240w-mixer-amplifier-100v-2ohm","provider":"Audio Volt ","version":"1.0","type":"link"}
