The 4-channel DJM-A9 raises the bar for club standard mixers boasting huge upgrades compared to its predecessor, the DJM-900NXS2 with stunningly clear sound quality, enhanced playability and connectivity, and a host of new features to help you take your performances to the next level. The Pioneer DJ DJM-A9 4-Channel Professional DJ Mixer has also been improved as a musical instrument for more emotional and dynamic performances, while retaining the functions and layout that have become club standards.Stunning Clear Sound QualityThe next-generation club sound of the DJM-A9 comes from extensive development and fine tuning of existing technology from previous units, plus brand-new components. The channel input section is equipped with an ESS Technology 32-bit high-quality A or D converter for crystal-clear, high-resolution sound, while the master and booth output sections employ 32-bit high-quality D or A converters from the same brand so you can experience sound from the booth monitors that’s the same as the crowd hears on the dance floor. Even the sound quality of the microphone input and headphone outputs has been improved with carefully selected new parts and design optimization.Evolved PlayabilityIncreased spacing around the EQ knobs gives you the room to twist your fingers and high-grade, bright LEDs in the channel section make it easier than ever to get a visual grasp on sound levels. You can perform more dynamically than ever thanks to the frequency response of the isolators, which have been optimized to make the most of the latest music production traits. And, with higher quality, slicker channel faders than the DJM-900NXS2, plus the third-generation Magvel Fader crossfader, you can enjoy silk-smooth mixing and rapid, stable scratching.Sound Color FX with World’s First Center Lock KnobTurn on the brand-new Center Lock feature and, when you’re using the popular Sound Color FX, each knob will stop turning when you reach the center position. This means you can twist the knob as quickly as you like, taking the effect right up to the maximum of the hi, or down to the minimum of the low parameter, without the risk of going too far and switching to the opposite parameter. When you turn Center Lock off, the Sound Color FX knobs work in the same way as those on the DJM-900NXS2.Newly Advanced Beat FXA new color display helps you to quickly and accurately understand the status of the selected effect, and it features lighting that corresponds with the X-Pad’s horizontal arrangement, enabling more intuitive control with a simple finger slide. You can use the X-Pad to change the Echo and Ping Pong effects to create a unique analog tape-style sound. And, within the 14 total Beat FX, there are 3 new ones (Mobius, Triplet Filter, and Triplet Roll) you can use to add extra variation to your performances.Even better, the channel selector is now a dedicated button, enabling you to quickly apply effects to your chosen channel.
