Numark - Dimension 3

The Dimension 3 offers 1300 watts of clean power output. This amplifier has many unique DJ driven features and plenty of power. Besides the cosmetic appeal the unit also has an internal crossover so the DJ can power their subwoofer and main speakers with the same amplifier, simplifying user operation and equipment setup. The unit also has a unique front panel stereo/mono input selector and rear panel Banana Speakon connectors.

The unit is designed to provide a good combination of power, audio clarity and reliable operation. The basic circuit has been kept as simple as possible to reduce the amount of components, thereby shortening the signal path, and reducing coloration and the chance of component failure. However, we opted to add what we regard as essential protection against overheating, short circuits and power on transients.

An efficient heat dissipation system, comprising a high surface area heatsinks coupled with dual fans, ensures quiet and reliable cooling.

The sound quality and sturdy construction makes this amp ideal for a multitude of amplification tasks, from installations, mobile DJs, home studios, houses of worship and touring bands.
