As you wander through an upscale hotel or convention center, you may notice the myriad of speakers located in the lobby, the elevators and each floor. You’ll typically find a whole lot of speakers and all those speakers have to be driven by amplifiers hidden somewhere in the building. Up until recently, those amplifiers have traditionally been high-powered, energy sucking, heat producing, inefficient behemoths-not exactly green-and likely to cost their owners a pretty penny both at and after the sale.
Fortunately, Crestron, makers of super cool home automation and distributed audio solutions (among other things), has decided to make a greener option for those in need of distributed audio amplifiers. Not only are these amps a fraction of the size of their distributed audio ancestors, but they sip, rather than guzzle, electricity while providing what Crestron says is very high quality audio.
The new line of amps from Crestron are named, rather aptly, “AMP”. There appear to be five different models. The AMP-2210S and AMP-3210S seem best suited for large home audio projects, are 11 inches deep and offer a choice of two or three channels to drive both 4 and 8 ohm speakers at 120 watts and 210 watts, respectively. The AMP-2210T and AMP-3210T appear intended for smaller commercial applications and can crank out power to either two or three channels at 210W @ 4ohms, 120W @ 8ohms and 120W at 70/100V.
The AMP-2210HT is the fifth and most robust model, offering 210 watts at 70V and, according to Crestron, is intended for larger commercial building applications such as hotels, malls, and similar large public spaces where tons of speakers on multiple floors will demand serious support.
The company says its new amps combine high power with excellent energy efficiency. The amps also offer an auto on/off system that shuts the amps down after 30 minutes of non-use and pops back on as soon as they see a signal.
