DJ Control AIR Street Edition - 3.5mm, 6.5mm, 2 jog wheels, PC/Mac, Black <b>2-deck DJ controller</b>
- 2 jog wheels with pressure detection;
- Velocity sensitive pads;
- Air control: 1 contactless control.

<b>Pressure-detecting jog wheels</b>
- Scratch by pressing on the jog wheels, as naturally as with a vinyl record;
- Jog wheels also control pitch bend and browsing within tracks.

<b>8 pads with velocity detection</b>
- The pads control the sampler, loops and effects;
- The inner backlight shows the pads’ activation;
- Pads can be set as binary On/Off controls, or gradual controls.

<b>Air control: a contactless sensor to control the mix from above, without even touching the device</b>
- DJ Control Air converts the distance to your hand into a MIDI command;
- No need to touch the controller: one command of the mix without any physical contact;
- Compatible with all light conditions.

<b>Built-in audio outputs for mixing and previewing tracks</b>
- 1/8" (3.5 mm) stereo mini-jack output for the mix;
- 1/4" (6.35 mm) stereo jack output for previewing tracks.

<b>Lime-green rubber caps on faders and rotary buttons</b>
- Smooth touch for ergonomic use, trendy lime green colour;
- Sharp visual contrast with the black controller, you see the caps position in low light conditions.

<b>Air control</b>
Why is the controller called DJ Control Air? Air stands for Adjustment by InfraRed: it is a contactless control.
- The DJ places his or her hand flat over the infrared beam.
- The controller calculates the distance between the sensor and the hand, and converts it into a gradual MIDI command.
- This MIDI command modulates a setting in the DJ software.

<b>Does Air control require specific light conditions? No, Air control functions under any light conditions.</b>
- The infrared light beam projected towards the hand is invisible.
- The sensor captures the infrared reflection on the hand, and uses the reflection to calculate the hand’s distance.
- The reflection is the same in both daylight and low light conditions, allowing Air control to be used during the day, at night or in places with weak lighting.
- Air control functions with all flesh tones. The only incompatibility is the use of black gloves (as the infrared sensor would not be able to detect the reflection).

<b>8 pads</b>
2 sets of 4 pads control loops, sampler and effects commands.
- The DJ taps on the pads with his or her fingertips to send commands such as looping, sampler or effects.
- The pads light up when touched.
- In addition to a binary On/Off command, each pad can transfer velocity information to modulate the command.
- For example: in sampler mode, the velocity can control the volume of a sample’s playback. The playback volume depends on how soft or how hard the DJ taps on the pad.

<b>Pressure-detecting jog wheels</b>
The jog wheels detect the pressure from the user’s hand.
- With scratch mode enabled, the jog wheels scratch when the hand’s weight is detected, and stop scratching when the hand’s weight is no longer detected. This allows the DJ to:
- stop playback by pressing on the jog wheel.
- restart playback by lifting up his or her hand.
- scratch by turning the jog wheel while pressing down, and stop scratching by lifting up his or her hand.
- bend the pitch (if playback is on) / browse within tracks (if playback is off) by turning the jog wheels using their outer ring, to avoid applying downward pressure.
- With scratch mode disabled, the jog wheels bend the pitch or browse within tracks when the jog wheels are turned, regardless of the pressure applied.

<b>DJ deck</b>
Originally, a deck was a turntable, referred to as a vinyl turntable, used by DJs to play music. Today, DJs use the term deck to refer to any music player, CD player or MP3 player equipped with a wheel to advance/rewind within a piece as with a vinyl turntable. A dual-deck device is a device with two wheels which control playback of two different pieces of music.

<b>Mixing board</b>
Device to which a variety of sound sources can be connected and mixed together: the mix is adjusted using a cross later, volume faders and several EQ knobs.

<b>Monitoring</b>
For a DJ, monitoring consists of listening to another piece of music other than the one being played for the audience: normally, a DJ listens to the next piece of music to be played.

<b>MP3</b>
Le MPEG-1/2 Audio Layer 3, plus connu sous son abréviation de MP3, est la spécification sonore du standard MPEG-1, du Moving Picture Experts Group (MPEG). C'est un algorithme de compression audio (voir aussi codec) capable de réduire drastiquement la quantité de données nécessaire pour restituer de l'audio, mais qui, pour l'auditeur, ressemble à une reproduction du son original non compressé, c'est-à-dire avec perte de qualité sonore significative mais acceptable pour l'oreille humaine.
