Welcome to music, the way it was meant to be heard. The TDAI-3400 is a stylish integrated stereo amplifier that has set a new standard in sound. In addition to being fully digital and having flexible upgrade modules and RoomPerfect™ room correction technology, the TDAI-3400 includes a media player, programmable voicing and 400 watts per channel.
With most systems, more than 50% of the sound you hear comes not from your speakers, but from your room. The placement of your speakers and the shape and dynamics of the room—echoes, reflections, and absorption—have great influence on what you hear.
RoomPerfect™ is the most advanced and user-friendly room correction system in the world. It identifies the characteristics of your speakers and the influence of your room, and it takes the room out of the equation. With RoomPerfect™, your speakers sound exactly as the manufacturer intended them to, not the way your room makes them sound.
