{"product_id":"adastra-rm240d-100v-mixer-amplifier-with-dab-and-bluetooth","title":"Adastra RM240D 100V Mixer-Amplifier with DAB+ and Bluetooth","description":"\u003ch5\u003eDescription\u003c\/h5\u003e\n\u003cp\u003eThe Adastra RM240D is a 5-channel mixer-amplifier built for commercial sound installations. It drives 100V line speakers across four switchable zones, plus a separate 'always on' output for priority alert speakers. You can also run standard low-impedance speakers down to a 4 Ohm load, with an optional 4-16 Ohm output for more flexibility. The unit is 2U 19\" rack mountable and comes with rack ears supplied, so it fits neatly into an existing setup.\u003c\/p\u003e\n\u003cp\u003eInput options cover most installation needs. There is an XLR input with switchable +20V phantom power, two mic\/line jack inputs and two RCA line inputs, along with a single RCA line output. Built-in audio sources include a DAB+\/FM radio tuner, front-mounted USB\/SD ports and Bluetooth 5.0, all handled through an integrated media player for straightforward playback. The Bluetooth receiver carries a unique serial ID, which helps when several units share the same space. Front controls give you level for each channel group plus bass, treble and master volume.\u003c\/p\u003e\n\u003cp\u003eA switchable VOX voiceover feature automatically lowers the background music when a signal is picked up on mic input 1, useful for paging and announcements. On the rear panel, 24V emergency mute contacts mute all inputs except mic 1 when triggered, tying the amp into a wider alarm or evacuation system. Power comes from 230Vac mains or a 24Vdc backup supply via screw terminals, so the RM240D keeps running during a mains failure. Note that US listings may refer to the amp as an 'amplifier' rather than 'mixer-amp', but the function is the same.\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\u003e7.37KG\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eDimensions\u003c\/td\u003e\n\u003ctd\u003e433mm x 320mm x 88mm\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eFuse\u003c\/td\u003e\n\u003ctd\u003eT5A\u003c\/td\u003e\n\u003c\/tr\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\u003ePower supply\u003c\/td\u003e\n\u003ctd\u003e170-264Vac, 50Hz (IEC)\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\u003eInputs\u003c\/td\u003e\n\u003ctd\u003eMic XLR, 2 x mic\/line jack, 2 x RCA line\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eInput sensitivity : mic 1 (balanced)\u003c\/td\u003e\n\u003ctd\u003e-53dBV\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eInput impedance : mic 1\u003c\/td\u003e\n\u003ctd\u003e5k Ohm\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eInput sensitivity : line (unbalanced)\u003c\/td\u003e\n\u003ctd\u003e-15dBV (-18.5dBV line 5)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eInput impedance : inputs 2-5\u003c\/td\u003e\n\u003ctd\u003e1k Ohm\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eLine output\u003c\/td\u003e\n\u003ctd\u003eRCA\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eSpeaker outputs\u003c\/td\u003e\n\u003ctd\u003e4 switched + 1 non-switched 100V \/ 4-16 Ohm \/ COM\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\u003eControls\u003c\/td\u003e\n\u003ctd\u003eMic1, mic\/line2+3, line4+5, bass, treble, master volume\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eEqualiser : bass\u003c\/td\u003e\n\u003ctd\u003e100Hz ±10dB\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eEqualiser : treble\u003c\/td\u003e\n\u003ctd\u003e10kHz ±10dB\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eRear panel switches\u003c\/td\u003e\n\u003ctd\u003ePhantom, Vox, Mic\/Line (2 + 3)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003ePhantom power\u003c\/td\u003e\n\u003ctd\u003e+20V (mic 1 XLR, switchable)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eAudio source\u003c\/td\u003e\n\u003ctd\u003eDAB+\/FM tuner, USB\/SD player, Bluetooth receiver\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eEmergency control\u003c\/td\u003e\n\u003ctd\u003e24V contacts - mute all except Mic.1 when triggered\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eTHD\u003c\/td\u003e\n\u003ctd\u003e\u0026lt;1.0%\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\/953225UK_59108985-f3d5-4ff4-a822-d6dbe33f8943.pdf?v=1785059371\" target=\"_blank\"\u003eProduct Manual\u003c\/a\u003e\u003c\/p\u003e\n\u003ch5\u003eFrequently Asked\u003c\/h5\u003e\n\u003cp\u003e\u003cstrong\u003eHow many speaker zones does the RM240D support?\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eIt has four switchable 100V outputs plus one unswitched output.
