It gives you three switchable mic\/line inputs, an RCA line input and a 3.5mm aux input, each with its own front panel volume control alongside a master output control. That makes it a practical choice for small to medium PA installations where you need to blend a few sources without taking up much rack space.\u003c\/p\u003e\n\u003cp\u003eOutput runs to either a 100V line or an 8 ohm speaker load via a removable screw terminal (Euroblock) connector on the rear panel, so it suits both distributed 100V systems and standard low impedance setups. The amplifier uses a Class D design with a transformer output, and there's a global 2-band EQ to shape the overall sound. Channel 1 offers switchable +20V phantom power for condenser microphones, available on the XLR or the rear terminals. Twenty-four volt fire alarm mute contacts let the amp drop its output when triggered by an alarm system.\u003c\/p\u003e\n\u003cp\u003eThe UA240 comes with rack-mounting hardware that can be set up two ways: mount two units side by side in a standard rack, or fix a single unit flat against a wall or under a worktop. Rated performance includes THD below 0.4% at 1kHz, a signal to noise ratio of 80dB on line inputs, and a frequency response of 100Hz to 18kHz. Input sensitivity sits at -10dB for line and -45dB for mic, with a 1k ohm input impedance on the mic\/line channels. It's a straightforward, flexible amp for background music, paging and general announcements.\u003c\/p\u003e\n\u003ch5\u003eSpecification\u003c\/h5\u003e\n\u003ctable class=\"spec_table\"\u003e\u003ctbody\u003e\n\u003ctr\u003e\n\u003ctd\u003eOutput power : rms\u003c\/td\u003e\n\u003ctd\u003e240W\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eWeight\u003c\/td\u003e\n\u003ctd\u003e3.17KG\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eDimensions\u003c\/td\u003e\n\u003ctd\u003e350mm x 210mm x 44mm\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003ePower supply\u003c\/td\u003e\n\u003ctd\u003e230Vac, 50Hz (IEC)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eAmplifier : construction\u003c\/td\u003e\n\u003ctd\u003eClass D + transformer output\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eInputs\u003c\/td\u003e\n\u003ctd\u003eMic\/line (combo), 2 x mic\/line (6.3mm), line (RCA), aux (3.5mm)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003ePhantom power\u003c\/td\u003e\n\u003ctd\u003e+20V CH1 (XLR or rear terminals)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eLine output\u003c\/td\u003e\n\u003ctd\u003e2 x RCA (mono)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eSpeaker output\u003c\/td\u003e\n\u003ctd\u003eEuroblock terminals: 100V \/ 8 Ohm or 2 Ohm \/ Com\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eMute\u003c\/td\u003e\n\u003ctd\u003e24V relay contacts\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eTHD\u003c\/td\u003e\n\u003ctd\u003e\u0026lt;0.4% @ 1kHz\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eInput impedance\u003c\/td\u003e\n\u003ctd\u003e1k Ohm (mic\/line)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eInput sensitivity\u003c\/td\u003e\n\u003ctd\u003e-10dB (line), -45dB (mic)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eSNR\u003c\/td\u003e\n\u003ctd\u003e80dB (line), 75dB (mic)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eFrequency response\u003c\/td\u003e\n\u003ctd\u003e100Hz - 18kHz\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\u003c\/table\u003e\n\u003ch5\u003eDownloads\u003c\/h5\u003e\n\u003cp\u003e\u003ca href=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0729\/8993\/3835\/files\/953013UK.pdf?v=1785057213\" target=\"_blank\"\u003eProduct Manual\u003c\/a\u003e\u003c\/p\u003e\n\u003ch5\u003eFrequently Asked\u003c\/h5\u003e\n\u003cp\u003e\u003cstrong\u003eDoes the UA240 work with 100V line speakers?\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eYes.
