Location

Install the unit in a well-ventilated location where it will
not be exposed to high temperatures or humidity.
÷ Do not install the unit in a location which is exposed to

direct rays of the sun, or near stoves or radiators.
Excessive heat can adversely affect the cabinet and
internal components. Installation of the unit in a damp or
dusty environment may also result in a malfunction or
accident. (Avoid installation near cookers etc., where the
unit may be exposed to oily smoke, steam or heat.)

÷ When the unit is used inside a carrying case or DJ booth,

separate it from the walls or other equipment to improve
heat radiation.

Condensation

When this unit is brought into a warm room from previously
cold surroundings or when the room temperature rises
sharply, condensation may form inside, and the unit may not
be able to attain its full performance. In cases like this, allow
the unit to stand for about an hour or raise the room
temperature gradually.

Cleaning the Unit

÷ Use a polishing cloth to wipe off dust and dirt.

÷ When the surfaces are very dirty, wipe with a soft cloth

dipped in some neutral cleanser diluted five or six times
with water and wrung out well, then wipe again with a dry
cloth. Do not use furniture wax or cleaners.

÷ Never use thinners, benzene, insecticide sprays or other

chemicals on or near this unit, since these will corrode the
surfaces.

CAUTIONS REGARDING HANDLING

FEATURES

1) Designed for high sound quality

Electronic parts have been carefully selected and internal
circuitry redesigned to provide the shortest-possible signal
paths, thus realizing true club sound with power to spare.

2) Effects create new performance potential

1 50 effects in 2 systems: Each channel can be preset with

three of 50 possible effects. Sequential effects can be
called up seamlessly merely by touching the names of the
effects on the top panel’s LCD touch panel, creating a new
level of DJ performances.

2 Fader effects: an industry first, Pioneer’s “fader effects”

allow the user to change effect parameters by operating
the sliders for the cross fader or channel fader, thus
providing greater operating facility compared to
conventional rotating dials, while also allowing the DJ to
apply scratch sounds to effects and create other new
remix performances.

3 Beat effects: linked to track tempo (BPM: beats per

minute), “beat effects” allow the user to apply echo, delay
and other effects with perfect timing.

4 Effect frequency selection: effects can be targeted at HI,

MID, and LOW frequency ranges as desired; simultaneous
multiple frequency ranges can also be specified.

3) Ergonomic, user-customizable cross fader

1 Cross-fader “feeling” adjustment: the specific physical

sensation of cross fader operation is all-important to the
DJ; the “feeling” adjustment provided in this mixer is an
industry first, allowing the user to adjust the physical
sensation of the slider to personal preferences, for the
smoothest possible cross fader operation.

2 Independent cross fader lag cut: the mechanical play

(the lag distance before sound begins) at each end of the
cross fader slider can be adjusted using the fader lag cut
function, thus allowing adjustment of the sound cut when
performing scratch play.

3 Independent cross fader curve: an industry first, the

right-left independently adjustable (33 steps) cross fader
curve control goes beyond the symmetrical type of cross
fader curve on conventional mixers, thus broadening DJ
performance capabilities.

4 “Contactless fader” mechanism: based on Pioneer’s

own proprietary technology, this new contactless optical
fader assures durable and stable operation under the
severest of DJ performance conditions.

4) Touch-panel display provides both wide

information and ease of operation

The top panel LCD display includes a fader edit monitor that
displays information about user fader settings (curve, reverse,
cut lag, etc.) together with other information necessary for
remix and DJ play. The use of a touch panel also makes it
possible to select effects easily with a single touch.

5) Other features

1 An industry first for DJ mixers, this unit supports use of an

optional foot switch to allow quick ON/OFF control of
effects.

2 When connected via a control cord to a Pioneer DJ CD

player (sold separately), operation of the fader can be used
for automatic “fader start” play.

3 “Fader reverse” function allows reversing of the

directions of fader operation movement.

4 Delicate 33-step channel fader curve settings.
5 Can be connected in series to other mixers for “session”

output of mixed sounds.
