The AT541NC Class D Mono Block amplifier is an impressively compact high power and efficient amplifier that is equally at home as a pair of dedicated Left/Right main channel amplifiers or Left/Center/Right front speaker/amplifier power trio. AT541NC is designed with balanced bridged output modules and paired with ATI-designed custom gain stages and a linear power supply. Each pair of balanced bridged Hypex N-Core® amplifier modules produce up to 500 watts with 4 ohm loudspeakers, recognized by the amplifier as 2 ohm loads.
