It handles three switchable mic\/line inputs, an RCA line input and a 3.5mm Aux input, each with its own front panel volume control, plus a Master output control. This layout suits small to medium PA installations where you need a few sources brought together and sent to one output.\u003c\/p\u003e\n\u003cp\u003eMono output runs to either 100V line or an 8 ohm speaker load, connected through a removable screw terminal (Euroblock) connector on the rear panel. Construction is Class D with a transformer output stage, and switchable +20V phantom power is available on channel 1 via XLR or the rear terminals. There are 24V fire alarm mute contacts for integration with building alarm systems, along with two RCA line outputs for feeding another amplifier or recorder.\u003c\/p\u003e\n\u003cp\u003eThe UA90 ships with rack-mounting hardware that can be set up two ways: to fit a single unit against a wall or under a worktop, or to mount two units side by side in a standard rack. Rated figures include THD below 0.4% at 1kHz, a frequency response of 100Hz to 18kHz, and signal-to-noise of 80dB on line and 75dB on mic inputs. It gives you a straightforward, flexible base for background music and paging over a 100V line.\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\u003e90W\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eWeight\u003c\/td\u003e\n\u003ctd\u003e2.99KG\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eDimensions\u003c\/td\u003e\n\u003ctd\u003e300mm x 210mm x 44mm\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003ePower supply\u003c\/td\u003e\n\u003ctd\u003e170-264Vac, 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\/953189UK_31391833-e0a8-4b67-8117-7f51478c46bc.pdf?v=1785058990\" target=\"_blank\"\u003eProduct Manual\u003c\/a\u003e\u003c\/p\u003e\n\u003ch5\u003eFrequently Asked\u003c\/h5\u003e\n\u003cp\u003e\u003cstrong\u003eCan the UA90 drive both 100V line and 8 ohm speakers?\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eYes.
