The Pioneer DM-40D Speakers feature a Class D amplifier with 96KHz sampling to bring you the best sound for your mix. With the flick of a switch, the DSP settings will automatically adjust making these the perfect monitors for both DJ's and music producers. Advanced design for higher quality sound Each DM Series speaker includes a Class D amplifier with 96 kHz sampling DSP to produce pure, balanced bass sound. You can also enjoy a wide sweet spot and 3D stereo sound wherever you are in the room thanks to the DECO convex diffusers, which have an advanced design compared to the original DM-40 speakers and help deliver crystal-clear high frequencies in every direction. When you need to turn up the volume, the woofer creates extra power and it’s perfectly aligned with the tweeter so you’ll hear all sound frequencies clearly. The grooves on the ducts same as DM-40 reduce air friction so that bass is tight and punchy, even if you position the speakers against a wall. Plus, the curved front edges provide maximum rigidity and minimum resonance for clean audio at any volume level. 2-way sound mode optimised for DJing and music production There’s no need to decide whether you want a set of monitors that are best for DJing or making music, because the DM Series speakers are perfect for both. Just flip the switch to choose either DJ mode or Production mode and the DSP settings will be optimised for the task, leaving you free to concentrate on your mix. Easy to use with different DJ or production equipment With RCA and mini jack terminals you can connect different kinds of gear such as DJ controllers and mixers, ,the laptop or built-in soundcard you use for producing your own music. Connecting and disconnecting your headphones is simple via the socket on the front panel, and there’s no need to reach around the back of the speakers to adjust the volume because the level knob is also right in front of you.
