It takes standard line level audio from a mixer or an RM series mixer amplifier, so you can add power to a system without adding another source. As a Class-D design it stays efficient and lightweight, and it fits a standard 19\" rack in a 2U housing. The RS480 delivers 480W, sitting at the top of the RS range alongside the 120W, 240W and 360W models.\u003c\/p\u003e\n\u003cp\u003eLine level inputs connect via RCA sockets or hard-wired removable screw terminals, also known as Euroblock terminals. A separate removable screw terminal handles 100V input, which lets you extend an existing 100V installation by wiring directly to the speaker feed, or run a long distance feed using standard double-insulated cable. Slave outputs can be cascaded onto further RS slaves, so you can build the system out as far as the job needs. A 24V terminal connects to a security or alert panel to mute the output during alarm triggering.\u003c\/p\u003e\n\u003cp\u003eSpeaker outputs run at 100V or low impedance, stable down to 2 Ohms, so you can connect multiple low impedance speakers if you prefer that approach. Master volume gives you level control on the front, and THD stays below 1.0%. Frequency response covers 90Hz to 20kHz on the 100V output and 17Hz to 90kHz at 2 Ohms. Power comes from a 175-264Vac 50Hz IEC supply. Whether you are powering a fresh install from a mixer output or expanding what you already have, the RS480 slots into the chain cleanly.\u003c\/p\u003e\n\u003ch5\u003eSpecification\u003c\/h5\u003e\n\u003ctable class=\"spec_table\"\u003e\u003ctbody\u003e\n\u003ctr\u003e\n\u003ctd\u003eFuse rating\u003c\/td\u003e\n\u003ctd\u003eT6.3A\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eOutput power : rms\u003c\/td\u003e\n\u003ctd\u003e480W\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eDimensions\u003c\/td\u003e\n\u003ctd\u003e433mm x 355mm x 89mm\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eWeight\u003c\/td\u003e\n\u003ctd\u003e10.40KG\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003ePower supply\u003c\/td\u003e\n\u003ctd\u003e175-264Vac 50Hz (IEC)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eInput signal\u003c\/td\u003e\n\u003ctd\u003eSlave line in (RCA\/screw terminal), 100V in (screw terminal)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eOutput : signal\u003c\/td\u003e\n\u003ctd\u003eSlave line out (RCA\/screw terminal)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eOutputs : speaker\u003c\/td\u003e\n\u003ctd\u003e100V or 2 Ohm min.
