It combines a five-input mixer with amplification in a single unit, so you can handle microphones, background music and announcements from one place. The Class D amplifier with transformer output gives you a mono output that runs at either 100V line or 8 ohms speaker load, connected through a removable screw terminal connector on the rear panel.\u003c\/p\u003e\n\u003cp\u003eYou get 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. Channel one offers switchable +20V phantom power for condenser microphones, available at either the XLR or the rear terminals. A global 2-band EQ lets you shape the overall sound. There are 24V fire alarm mute contacts on the rear, which is useful where the amplifier needs to work alongside an emergency system that takes priority over normal audio.\u003c\/p\u003e\n\u003cp\u003eThe UA120 ships with rack-mounting hardware that can be set up two ways. You can fit a single unit against a wall or under a worktop, or mount two units side by side in a standard 19-inch rack. Input sensitivity runs at -10dB for line and -45dB for mic, with THD below 0.4% at 1kHz and a frequency response of 100Hz to 18kHz. It sits within the wider UA Series, so if you need more power the 120W and 240W siblings share the same layout and controls.\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\u003e120W\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eWeight\u003c\/td\u003e\n\u003ctd\u003e4.13KG\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\/953012UK.pdf?v=1785057156\" target=\"_blank\"\u003eProduct Manual\u003c\/a\u003e\u003c\/p\u003e\n\u003ch5\u003eFrequently Asked\u003c\/h5\u003e\n\u003cp\u003e\u003cstrong\u003eHow many inputs does the UA120 have?\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eIt has five input channels: three switchable mic\/line inputs, one RCA line input and one 3.5mm Aux input.
