It pairs a class D amplifier with a transformer output stage, so you can drive either a 100V line or an 8 Ohm speaker load. Connections are made through screw terminals on the rear panel, and the mono output keeps wiring straightforward for background music and paging jobs.\u003c\/p\u003e\n\u003cp\u003eAudio sources are covered by an internal USB\/FM\/BT player, giving you a USB input, an FM tuner and a Bluetooth 5.0 wireless receiver in one unit. Bluetooth comes with a programmable ID, which helps when you have more than one amp in the same building and want to keep pairing tidy. On the input side there is a microphone input on 6.3mm jack, a line input on twin RCA (phono) and a 3.5mm aux input. Each section has its own front panel volume control, with a master volume over the top, so setting levels for a room is quick.\u003c\/p\u003e\n\u003cp\u003eHoused in a small chassis, the UM30 ships with hardware for mounting two units side by side in a 1U 19 inch rack space. It runs from 170-264Vac mains via IEC or from 24Vdc through screw terminals, with 24V relay contacts for mute. THD sits below 0.4% at 1kHz and frequency response runs from 100Hz to 18kHz. Line output is provided on twin RCA (mono) for feeding another amplifier or a recorder. For shops, offices and similar spaces it offers a lot in a small footprint.\u003c\/p\u003e\n\u003ch5\u003eSpecification\u003c\/h5\u003e\n\u003ctable class=\"spec_table\"\u003e\u003ctbody\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\u003eOutput power : rms\u003c\/td\u003e\n\u003ctd\u003e30W\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003ePower supply\u003c\/td\u003e\n\u003ctd\u003e170-264Vac, 50Hz (IEC) or 24Vdc\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\u003eAudio source\u003c\/td\u003e\n\u003ctd\u003eInternal USB\/FM\/BT player\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eBluetooth version\u003c\/td\u003e\n\u003ctd\u003e5.0\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eInputs\u003c\/td\u003e\n\u003ctd\u003e1 x mic (6.3mm), 1 x line (2 x RCA), 1 x aux (3.5mm)\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 outputs\u003c\/td\u003e\n\u003ctd\u003eScrew terminals - 100V \/ 8 Ohm \/ Com\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eDC power\u003c\/td\u003e\n\u003ctd\u003e24Vdc screw terminals\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\/953173UK_0d930d0f-2bd5-4199-b2d6-09c0262ec4df.pdf?v=1785058771\" target=\"_blank\"\u003eProduct Manual\u003c\/a\u003e\u003c\/p\u003e\n\u003ch5\u003eFrequently Asked\u003c\/h5\u003e\n\u003cp\u003e\u003cstrong\u003eCan the UM30 drive both 100V and low impedance speakers?\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eYes.
