By using low-impedance digital amplifier chip technology the Techconnect AMP2 module outputs a massive 2 x 20w RMS (at 8 ohms) but fits into the space of a Techconnect module. Digital amplifiers use no power unless they are amplifying program, so even on at full volume; unless it is receiving input it is effectively off. Digital amplifiers also have the advantage of running cold so a bulky heatsink is not necessary but dont let size deceive you: the Techconnect AMP2 can drive into a 4 ohm load allowing you to power up to four speakers. A clear display makes the product easy to use & a simple soft-control interface gives instant access to controls. Because the control panel can be installed anywhere in the room it is more convenient than traditional powered speakers where access to the controls can be awkward.
