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 alongside a master output control. The mono output feeds either a 100V line system or an 8 ohm speaker load, connected through a removable screw terminal (Euroblock) connector on the rear panel. It is a practical choice for small to medium PA installations such as shops, offices and background music setups.\u003c\/p\u003e\n\u003cp\u003eChannel one includes switchable +20V phantom power, available via XLR or the rear terminals, so you can run condenser microphones without a separate supply. The amplifier uses a Class D output stage with a transformer for the 100V line, and quoted total harmonic distortion (THD) sits below 0.4% at 1kHz. Frequency response runs from 100Hz to 18kHz, with input sensitivity of -10dB on line and -45dB on mic, and a signal to noise ratio (SNR) of 80dB line and 75dB mic. Input impedance on the mic\/line channels is 1k ohms.\u003c\/p\u003e\n\u003cp\u003eFor safety systems, the UA30 has 24V relay mute contacts that let a fire alarm interrupt the audio when triggered. Adastra supplies rack-mounting hardware in the box, and it can be configured to fit two units side by side in a rack, or to mount a single unit against a wall or under a worktop. The larger 120W and 240W models in the UA range add a global 2-band EQ, while the UA30 keeps things simple for smaller jobs where a straightforward mixer amp is all you need.\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\u003e30W\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eWeight\u003c\/td\u003e\n\u003ctd\u003e2.35KG\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eDimensions\u003c\/td\u003e\n\u003ctd\u003e249mm 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\/953183UK_e0a1288e-e94d-4a5d-8cbc-c9ad2554cd91.pdf?v=1785058909\" target=\"_blank\"\u003eProduct Manual\u003c\/a\u003e\u003c\/p\u003e\n\u003ch5\u003eFrequently Asked\u003c\/h5\u003e\n\u003cp\u003e\u003cstrong\u003eCan the UA30 drive 100V line speakers?\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eYes.
