Rane creates truly professional mixers for the world's best artists and finest sound systems. The new MP2015 lets you push harder with greater audio headroom in volume and filtering than other mixers. As an artist, the instruments you use undeniably influence your expression, inspire creativity and transform good into great. Like the world’s best piano or violin, this is an instrument of powerful capability. To be the best, you play the best.The MP2015 is the ultimate mixing instrument for today's forward-thinking DJ requiring the very best sound quality. This mixing instrument combines powerful and unique features, classic elegance, silky-smooth feel and rugged design.The control ergonomics have an intuitive and comfortable layout. The custom rotary potentiometers have exceptional feel, rated for a million cycles. The back-lit push switches are the same found on recording studio consoles. Durability extends to the control labels that will never wear off after decades of use.Let's talk about sound. This mixer is an audiophile's dream, meant to be appreciated on the highest-grade home stereo or mega-club loudspeaker system. Specifications are better than most recording studio components. The very best A/D and D/A converters are used, with a dynamic range of 116 dB and THD+N at 0.0009%. All processing is 32-bit floating point at a selectable 44.1, 48 or 96 kHz sample rate.Each of the four Deck inputs selects between a turntable or CD deck (analog or S/PDIF), an Aux line, USB port A or USB port B. The S/PDIF inputs have a dynamic range of 128 dB with ultra-low jitter. When using turntables, the RIAA curves are extremely accurate, with steep rumble filters included. The Gain control helps match Deck inputs to each other, with visual assistance from the 16-segment meters with peak-hold.Two USB ports allow simultaneous connection of two computers, enabling back-to-back sets between laptop DJs running different software without compromise or interruption. Each USB port supports 10 playback and 14 record channels. This lets most DAW programs simultaneously record all four decks, the Sub mix, the Session input and the Main mix. The dynamics of the MP2015 are perfect for DJs that prefer the uncompressed sound of WAV and FLAC files.A stack of customizable Filter sets make the MP2015 unique. First, tailor each channel source with High, Mid and Low tone controls with a range of +6 dB to full cut, whose crossover points can be changed through USB in the control panel. Then, each source has a switchable High-pass, Low-pass or High/Low-pass sweep effect Filter with an adjustable Resonance control. Finally, a built-in 3-band Isolator Equalizer on the main outputs adjusts each band from +10 dB to off, with adjustable Crossover points between Low / Mid and Mid / High. The Isolator (ISO) easily lets you play with the musical tension by emphasizing and isolating specific elements (beat, bass, vocal, high-hat, etc.) to control the ebb and flow during a mix. No other mixer on the market allows this much tone control variance.The Submix is great innovation for multi-track DJs, combining 1 to 4 channels plus the Session Input into a Submix, thereby controlling multiple tracks with one set of EQ, Filter, and volume controls. This means turning one knob instead of trying to turn several channel knobs at once. Quickly assign or un-assign any Input to the Submix, which has its own meter, headphone Cue, and USB record output. This is also where an external effects unit can be mixed in, and assigned to the Submix or the Main Mix. The Submix can also be used as a 5th input channel from the Session Input. No other mixer on the market provides this ease of multi-track use.The studio-grade Mic input accepts either a condenser mic, dynamic mic, or wireless receiver. 48V phantom power is available for a condenser mic. A Duck switch temporarily reduces the music volume for a professional voice-over, and a Tone control helps varied mics sound clear over the music.Rane doesn’t scrimp on the Main Mix, using balanced XLR Main Outputs and TRS Booth Outputs, each with a Level control. Session Outputs have their own Output Level control, available on analog RCA jacks or a digital S/PDIF jack. Session Inputs and Outputs also provide both analog and digital connections. The S/PDIF Session connections allow recording or chaining mixers together without any analog conversion.The headphone cue system allows mono Split or Stereo Cue/Mix Panning, with headphone jacks conveniently located on the front and top of the mixer.
