1 Designed for high sound quality
Analog signals are sampled at 96 kHz/24-bit, comparable to
professional performance levels. Mixing is performed with the same
type of 32-bit DSP as used in the DJM-1000 and DJM-800, thus
eliminating any loss in fidelity, and producing clear and powerful
club sound optimally suited for DJ play.
2 3-band equalizer with kill function
Equalizer functions are provided for each of the three bandwidths HI,
MID, and LOW, and a kill function is provided to drop the attenuation
level to
.
3 Wide variety of effects
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
inputs and master outputs to the left and right channels of
monitor headphones.
¶ Full lineup of input/output systems. Provided with two each of CD
and LINE/PHONO (MM type) inputs and two microphone inputs
for a total of six input systems, together with two output systems.

CONNECTIONS
CONNECTING INPUTS
Pioneer DJ CD players
Connect a DJ CD player's audio output connectors to one of the
channel 1 to 2 CD input connectors, and connect the player's control
cable to the corresponding channel's CONTROL connector.
Set the connected channel's input selector switch to [CD].
Analog turntable
To connect an analog turntable, connect the turntable's audio output
cable to one of the channel 1 to 2 PHONO/LINE input connectors. Set
the corresponding channel's PHONO/LINE switch to [PHONO], and
set the channel's input selector switch to [PHONO/LINE]. The DJM-
400's PHONO inputs support MM cartridges. Connect the turntable's
ground wire to the DJM-400's SIGNAL GND terminal.
Connecting other devices with line level output
To use a cassette deck or other CD player, connect the component's
audio output connectors to one of the channel 1 to 2 PHONO/LINE
input connectors. Then set the corresponding channel's PHONO/
LINE switch to [LINE], and the input selector switch to [PHONO/LINE].
Microphone
The MIC1 and MIC2 jacks can be used to connect microphones with
Ø6.3 mm phone plugs. Set MIC/AUX switch to [MIC] position.
Auxiliary input connectors
The MIC1 and MIC2 jacks can also be used together as a pair of stereo
line input connectors to connect a component equipped with line
level output connectors. Connect the component's L channel to MIC1
(AUX(L)) jack and the R channel to the MIC2 (AUX(R)) jack. Then set
the MIC/AUX switch to [AUX] (this connection requires the use of
Ø6.3 mm phone plugs).
CONNECTING OUTPUTS
Master output
This unit is furnished with MASTER OUT 1 and MASTER OUT 2
output systems, both of which support the use of RCA plugs.
If the unit's STEREO/MONO switch is set to [MONO], the master
output will be a monaural combination of L+R channels.
Always turn off the power switch and disconnect the power plug from its outlet when making or changing connections.
