1)Beat effects

The “beat effects” so popular on the DJM-600 have been given
further evolution. Effects can be applied in linkage to the BPM (Beats
Per Minute) count, thus allowing the production of a variety of
sounds. Some of the effects include delay, echo, filter, flanger,
phaser, robot, and roll.

2)Beat select buttons

Automatically set the effect time linked to the BPM. Allows selection
of desired BPM for synchronizing beat effects.

3)IN-LOOP sampler

Detects the current track’s BPM and records up to 5 of 4-beat sources
in banks, and plays a loop in time with the track’s BPM.

4 2 MIC input, AUX switching

Equipped with 2 MIC input jacks that can be switched to AUX,
allowing use as a third LINE input.

5 Auto talk-over

The auto talk-over function automatically reduces track volume when
microphone input is detected.

6 Other functions

¶ A control cable can be used to connect the unit to a Pioneer DJ CD

player, thus allowing playback to be linked to operation of the
fader (“fader start play”).

¶ “Fader curve adjustment” function allows modification of the

cross fader curves.

¶ “Auto BPM counter” provides visual representation of a track’s

tempo.

¶ Monitor auto assignment function can be used to assign channel

FADER START FUNCTION

By connecting the optional Pioneer DJ CD Player control cable, the
channel fader and cross fader can be used to start CD playback.
When the mixer’s channel fader lever or cross fader lever are moved,
the CD player is released from the pause mode and automatically –
and instantly – begins playback of the selected track. Also, when the
fader lever is returned to its original position, the CD player returns to
its cue point (back cue), thus allowing “sampler” type play.

Cross fader start play and back cue play

When the CD player assigned to channel 1 is set to standby at a cue
point, moving the cross fader lever from the right (2) side toward the
left (1) side, automatically starts play on the channel 1 CD player.
When the cross fader lever reaches the left (1) side, the CD player
assigned to channel 2 goes to back cue (returns to cue point). Also,
when the CD player assigned to channel 2 is set to standby at a cue
point, moving the cross fader lever from the left (1) side to the right
(2) side, automatically starts playback on the channel 2 CD player.
When the cross fader lever reaches the right (2) side, the channel 1
CD player goes to back cue (returns to cue point).
* The back cue is performed even if the input selector switch is not

set to [CD].

EFFECT FUNCTIONS (TYPES OF BEAT EFFECTS)

EFFECT FUNCTIONS

This unit is equipped with a total of 8 basic effects using beat effects
and in-loops linked to the BPM. By changing the parameters for each
effect, a wide variety of new effects can be produced. By using the
BEAT/BANK buttons to set the time parameters, an even wider
assortment of beat effects can be produced.

TYPES OF BEAT EFFECTS

1. DELAY (One repeat sound)

This function allows a delay sound with beat of 1/2, 3/4, 1/1, 2/1
or 4/1 to be added quickly and simply. For example, When a 1/2
beat delay sound is added, four beats become eight beats.
Also, by adding a 3/4 beat delay sound, the rhythm becomes
syncopated.

Example

Original
(4 beats)

1/2 delay
(8 beats)

4. FLANGER

In units of 1/1, 2/1, 4/1, 8/1 or 16/1 beat, 1 cycle of flanger effect
is produced quickly and easily.

Example

Short
delay

1 cycle = 1/1, 2/1, 4/1, 8/1 or 16/1 beat

5. PHASER

In units of 1/1, 2/1, 4/1, 8/1 or 16/1 beat, 1 cycle of phaser effect
is produced quickly and easily.

Example

Phase shift

1 cycle = 1/1, 2/1, 4/1, 8/1 or 16/1 beat

2. ECHO (Multiple repeat sounds)

This function allows an echo sound with beat of 1/2, 3/4, 1/1, 2/1
or 4/1 to be added quickly and simply.
For example, when a 1/1 beat echo sound is used to cutoff the
input sound, a sound in synch with the beat is repeated together
with fadeout.
Also, by adding a 1/1 beat echo to the microphone, the
microphone sound repeats in synch with the music beat.
If a 1/1 beat echo is applied to the vocal portion of a track, the
song takes on an effect reminiscent of a “round”.

Example

1 beat

Cuts input
sound

1 beat

3. FILTER

In units of 1/1, 2/1, 4/1, 8/1 or 16/1 beat, the filter frequency is
moved, greatly changing the sound coloration.

Example

6. ROBOT

Generates a sound effect resembling that produced by a robot.

7. ROLL

Sounds of 1/2, 3/4, 1/1, 2/1 or 4/1 beat are recorded and output
repetitively.

Example

the display’s BPM counter will flash.

It may not be possible to measure some tracks accurately.

In this case, use the TAP mode for manual BPM input.

[Using the TAP Button for Manual BPM Input]

If the TAP button is tapped two times or more in synch
with beat (1/4 notes), the BPM will be recorded as the
average value recorded during that interval.

¶ When BPM mode is set to [AUTO], tapping the TAP button will

cause the BPM mode to change to the TAP mode, and the
interval at which the TAP button is pressed will be measured.

¶ When the BPM is set via the TAP button, the beat multiple

becomes “1/1” or “4/1” (depending on the effect selected),
and the time for 1 beat (1/4 notes) or 4 beats will be set as the
effect time.

[Using the BEAT/PITCH buttons for Manual BPM Input]

By pressing the BEAT/PITCH buttons (–, +) while holding
the TAP button depressed, the BPM can be changed.

¶ The BPM can be set from 40 to 999 in 1-step increments.

2. Set the effect selector to an effect other than [IN-LOOP
SAMPLER].

¶ See P. 10 regarding the various effects.

3.Set the effect channel selector to the channel you wish to
apply the effect to.

¶ If [MIC] is selected, the effect will be applied to both

microphone 1 and microphone 2.

4.Press one of the BEAT/BANK buttons to select the beat to
which you wish to synchronize the effect.

¶ Values can be selected from [1/2, 3/4, 1/1, 2/1, 4/1] or [1, 2, 4, 8,

16]. (The multiple differs depending on the effect. See page 10

for details.)

¶ The selected button will light.
¶ The effect time corresponding to the beat’s multiple is set

automatically.
Example: When BPM=120
1/1 = 500 ms
1/2 = 250 ms
2/1 = 1 000 ms

5. Use the BEAT/PITCH buttons (–, +) to select the beat
multiple to which you wish to synchronize the effects.

¶ When [+] is selected, the beat calculated from the BPM is

doubled, and when [–] is pressed, the beat calculated from the
BPM is halved.

¶ When the time parameter lies within the range calculated from

the BPM, the BEAT/BANK button corresponding to that value
lights. When the parameter falls between two beat values, both
BEAT/BANK buttons will flash. When the values is less than 1/
2 (1), the 1/2(1) button will flash, and when greater than 4/1
(16), the 4/1(16) button will flash.

¶ During use of [DELAY], [ECHO], or [ROLL] effects, if the [–], [+]

buttons are used to shift the multiple, the “3/4” value will be
skipped. However, the 3/4 multiple can be selected by pressing
the 3/4 button directly.

6. Rotate the LEVEL/DEPTH dial to set the quantitative
parameter for the selected effect.

¶ See P. 12 for details regarding the effect of rotating the dial on

the parameter.

7.

Set the ON/OFF button to ON to enable the selected effect.

¶ Each time the button is pressed, the effect is toggled ON/OFF.

(Whenever power is first turned ON, the function defaults to
OFF).

¶ The ON/OFF button flashes when effects are ON.
