It sits in a 19\" rack and uses a Class-D design that keeps it efficient and lightweight, so it won't add much weight or heat to your rack. Slave inputs accept standard line level audio from a mixer or an RM series mixer amplifier, and slave outputs can be cascaded onto further RS slaves when you need to build out a larger system.\u003c\/p\u003e\n\u003cp\u003eAll line level inputs connect via RCA sockets (phono in the UK) or hard-wired through removable screw terminals, also called Euroblock connectors. A separate removable screw terminal handles the 100V input, which lets the RS241 extend an existing 100V installation by connecting straight to the 100V speaker feed, or picking up a long-distance 100V feed over standard double-insulated cable. There's also a 24V terminal for connection to a security or alert panel, so the output mutes when an alarm is triggered. Speaker outputs run at 100V or low impedance, switchable and stable down to 2 Ohms, which means you can connect multiple low impedance speakers if you prefer.\u003c\/p\u003e\n\u003cp\u003ePower comes from a 175-264Vac 50Hz IEC supply, with a master volume control on the front and THD held below 1.0%. Frequency response is 90Hz-20kHz on the 100V setting and 17Hz-90kHz at 2 Ohms. The RS241 is one of a range of RS slave amplifiers, so you can pick the power rating that suits the job and add more units later as the system grows. It's a practical choice for powering a new install from a mixer output or for expanding a setup you already have in place.\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\u003eT2A\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\u003eDimensions\u003c\/td\u003e\n\u003ctd\u003e433mm x 267mm x 44mm\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eWeight\u003c\/td\u003e\n\u003ctd\u003e5.80KG\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.
