Product overview The AMP20 is a Mini Stereo PowerAmplifier with a power rating of 2 x 15 Watt, that lends itselfperfectly to small speaker systems requiring compact and economicalaudio solutions. It offers the ideal solution for applications such asclass rooms, offices and meeting rooms where only a small amount ofspeakers are required. The compact size and very highefficiency makes it perfectly suited to be hidden in a closet, on afalse ceiling or mounted under a desk or table. The combination of thestereo balanced line, with microphone input, makes it perfectly suitedfor applications where it should be used in combination with projectionscreens and video sources while a microphone is connected. Two gainpotentiometers make it possible to control the sensitivity and balancebetween music and speech, while a switch allows bridging of the outputchannels to obtain one channel with merged output power.A remote wall mixer can be connectedfor applications where local mixing for the inputs is desirable, whilelarge distances can be covered between the source and amplifier usingsimple CAT5 twisted pair cabling. The volume controller input allowsconnection of an additional wall controller for overall volume control.The Class-D Amplifier technology,standby mode and included switching power supply makes this devicecompliant to the highest energy efficiency and environmentalrequirements.
