Each of the six output zones works independently, so you can send different sources to different areas at the same time. Transformer outputs sit alongside the Class D amplification, giving you flexibility across both distributed and low-impedance speaker setups.\u003c\/p\u003e\n\u003cp\u003eSource options cover most needs without extra kit. There are three mic\/line inputs on combined XLR\/jack connectors, one auxiliary input on stereo RCA (phono), and a built-in USB\/SD\/FM player with a Bluetooth 5.0 receiver. Any of these can be matrix switched to any zone, so each room gets its own choice of audio. Microphone 1 has a variable override, and each mic input offers switchable +20V phantom power for condenser microphones. A master chime with its own volume control handles paging calls and alerts, and mic priority ducks the music when someone speaks.\u003c\/p\u003e\n\u003cp\u003eSetup and monitoring are handled from the front panel. A 6.3mm stereo headphone output with volume control lets you check any zone before it goes live, and there are matching RCA line monitor outputs. Each zone provides both line-level RCA and 100V\/8\/4 Ohm speaker terminals. Mute is triggered by +24V relay contacts for emergency or external control. The unit measures 433 x 89 x 302mm (2U rack), weighs 11kg, and runs from a mains supply of 170-264Vac at 50Hz via an IEC connector.\u003c\/p\u003e\n\u003ch5\u003eSpecification\u003c\/h5\u003e\n\u003ctable class=\"spec_table\"\u003e\u003ctbody\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\u003ePower output\u003c\/td\u003e\n\u003ctd\u003e6 x 40W rms\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eAudio source\u003c\/td\u003e\n\u003ctd\u003eUSB\/SD\/FM\/BT audio player\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eAmplifier : construction\u003c\/td\u003e\n\u003ctd\u003eClass D + transformer outputs\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eInputs\u003c\/td\u003e\n\u003ctd\u003e3 x mic\/line (XLR\/jack), auxiliary 2 x RCA\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eZone outputs: line\u003c\/td\u003e\n\u003ctd\u003e6 x RCA (mono)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eZone outputs: speaker\u003c\/td\u003e\n\u003ctd\u003e6 x terminal outputs 100V \/ 8 Ohms \/ 4 Ohms \/ Com\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003ePhantom power\u003c\/td\u003e\n\u003ctd\u003e+20V switchable to each XLR\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eMonitor outputs\u003c\/td\u003e\n\u003ctd\u003e6.3mm stereo phones, 2 x RCA line\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eMute\u003c\/td\u003e\n\u003ctd\u003e+24V relay contacts\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eTHD\u003c\/td\u003e\n\u003ctd\u003e\u0026lt;0.76% @ 1kHz\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eInput impedance\u003c\/td\u003e\n\u003ctd\u003e1k Ohms (mic\/line)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eInput sensitivity\u003c\/td\u003e\n\u003ctd\u003e-11dB (line), -46dB (mic)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eSNR\u003c\/td\u003e\n\u003ctd\u003e84dB (line), 82dB (mic)\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\u003eFrequency response\u003c\/td\u003e\n\u003ctd\u003e100Hz - 24kHz\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eDimensions\u003c\/td\u003e\n\u003ctd\u003e433mm x 89mm x 302mm\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eWeight\u003c\/td\u003e\n\u003ctd\u003e11.00KG\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\/953160UK_e370420d-b568-4e38-b9f4-5441916f1bfd.pdf?v=1785058539\" target=\"_blank\"\u003eProduct Manual\u003c\/a\u003e\u003c\/p\u003e\n\u003ch5\u003eFrequently Asked\u003c\/h5\u003e\n\u003cp\u003e\u003cstrong\u003eHow many zones can the RM406 drive independently?\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eIt has six independent output zones, and any input source can be matrix switched to any zone, so each area can play a different source at the same time.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eCan I use it with both 100V line and low-impedance speakers?\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eYes.
