PIONEER DJM-400
Compact 2 Channel Audio Mixer
Pioneer's new compact 2 channel mixer: the DJM-400 offers a host of beat effects and an in-loop sampler that offers a new level of flair for creative remixing. Built around the same digital processing technology and high quality components used in Pioneer’s DJM-1000, the new unit is a reliable and robust performer with exceptional audio quality.
‘Pioneer is a recognised innovator in professional DJ products and we’ve created a high-quality compact 2 channel mixer that’s tailored to the demands of DJs mixing in bars and smaller clubs and those mobile artists who demand a reliable, robust and high-quality mixer. The digital beat effects and in-loop sampler combined with the digital circuitry ensure that this compact mixer lacks for nothing in the creativity it provides and the quality of the sound,’ comments Mark Grotefeld, European Marketing Manager, Pioneer Europe.
Although the smallest mixer in Pioneer's range, the DJM-400 packs a wide variety of effects for creative mixing. The effects, that automatically detect the BPM of the music and sync to the beats include: Delay, Echo, Filter, Flanger, Phaser, Robot and Roll, all of which are processed at 24bits for the highest quality sound. In addition, by using the newly-adopted Beat Select Button, the DJM-400 automatically sets the effect time linked to the BPM for more intuitive play and responsive remixing.
The intelligent 96kHz/24bit sampler automatically detects the tempo of a track during playback, sampling it for four beats, then loops the sample. As the sampled audio is in sync with the beat of the track being played (no matter the tempo) the DJ is given more time to be creative. Samples are automatically beat matched and up to five samples can be stored in memory.
Each of the DJM-400's channels has a 3-band Kill EQ which ranges from +9dB to -∞(infinity) for total control of the sound.
The DJM-400 has been designed with as a perfect partner for the MP3 compatible CDJ-200 both in terms of style and function. When combined, these units create a small, portable yet powerful and robust DJ setup that offers exceptional versatility and performance.
The DJM-400 has a wide range of features. Some of the additional highlights include:
• MIC/AUX switch: to select from either two MIC connections or one stereo LINE connection
• Fader Start: connect a Pioneer CDJ player with a control cable and playback can be started by simply sliding the cross fader or channel fader
• Cross fader curve adjust: adapts to the DJs mixing style
• Talk over: automatically attenuates the volume by -20db so an MC can talk over the track
• Peak Level Meter: Allows you to check the peak level of the input audio for each channel or the master
FEATURES
Sound Quality
The DJM-400 is designed for high sound quality. Analog sounds are sampled at 96kHz. 24-bit which is the same as a lot of studio equipment nowadays. The actual mixing is performed using the same DSP as that is used for the DJM-1000 and the DJM-800. This ensures that the mixer delivers a clear and powerful sound.
As the DJM-400 processes the signals fully digital, please also use it that way. Meaning that you should not see the RED OVER Led's burning full time. Just keep them flashing as maximum (not constant) level. Use the first yellow LED as a good reference to what you put your gains to.
Input Selector
Use this to change from CD input to Phone/Line input.
Gain Trim
The Gain Trim has a range from infinite (silent) to +9db. The most optimal setting of the Trim is around 12 O'clock (0dB).
Channel EQ Range |
Treble |
-infinite ~ +9 dB (@ 13 kHz) |
Mid |
-infinite ~ +9 dB (@ 1 kHz) |
Bass |
-infinite ~ +9 dB (@70 Hz) |
The EQ function of the DJM-400 gives you the power of the Isolator of the DJM-1000. Providing you with the possibility to totally kill the frequency area of your choice (Low, Mid or High) in a range of +9dB ~ infinity kill. The frequencies of the EQ are the same as that from it's big brothers, the DJM-1000 and the DJM-800.
This is something that is already integrated to the EQ rotaries in Pioneer's DJM-600/DJM-707/DJM-800/DJM-909/DJM-1000 but has now been adjusted so it cuts down like an Isolator:
In horizontal position to the left, the EQ is cut down to about -12dB.
When you rotate further down than horizontal to the left, the frequency of the EQ 'killed' to a level of -infinite dB. The last part is in a logarithmical scale so it cuts down rapidly.
Fader Channels
The faders have lots of clean space.
Fader Curve Adjust
With a lowered selector switch the Cross Fader can be switched off (THRU) and can have a gentle and a steep slope, according to the shown figure.
Fader Start
When Fader Curve Adjust is THRU: This will trigger an output pulse over the Fader Signal output terminal on the back of the mixer. When a connected to a CD player you can remotely start/Cue the player.
When a fader curve is selected and the Cross Fader is activated the Fader Start will only work on the Cross Fader, it sends out a pulse to the channel depending on the side of the Fader.
Extra 3rd Input
When you insert 2 mono Jack connectors in both Microphone Inputs, you can use the 2 mic inputs (Jack connectors) combined as an extra AUX input, giving you an actual 3rd channel. This 3rd channel has limited EQ possibilities.
Microphone Level
You can set the level of both microphones in the range from infinite (not hearable/muted) to 0dB. Both microphones (MIC1 and MIC 2) can be used at the same time and on a different level by changing the rotary knob individually.
Microphone EQ |
Bass |
-12 ~ +0 dB (100 Hz) |
Treble |
-12 ~ +0 dB (10 kHz) |
This is more for gentle sound coloring than a real Equalizer. When set at center position there is no change. When rotated left (anti-clockwise) you cut of the high frequencies up to -12db when in approaching LOW marking. If you rotate the knob the other way around (clockwise) you decrease the low frequencies up to -12dB when in position near HI marking.
Microphone Selector
With this switch in the most left position (OFF) the microphone signal is muted and not hearable on the master. The same effect as if any of the Mic Levels is set to infinite.
When set to the center position (ON) that microphone signal is mixed with the Master, the level is set by the Mic Level rotary.
The most right position (TALK OVER) activates an input controlled mute, also called Talk Over. When a sound is detected on the Microphone Input higher than -15dB all channels will be attenuated with -20dB.
PFL Headphones Pre-Listening
By pressing 1 of these buttons you select a channel to be routed to the headphones.
When Master is pressed you can also press CH-1 or CH-2 to split the Headphones so you hear the Master signal on the Right and CH-1 or CH-2 (or both) on the Left side. This make pre- listening of a mix very easy.
Master
Obviously this control the Master Output level, keep the reading of the VU meters out of the RED to prevent distorting the output signal !
BPM Counter
The BPM counter uses the same technology as the Pioneer EFX-1000 and equals it's speed and accuracy. When flashing it is calculating the BPM, when it stops you have an accurate reading.
Auto/Tap
When Auto is pressed the button will be lit and Auto BPM Sync is activated. The effects will be synced to the tempo of the current track automatically.
When Tap is pressed it switches automatically. to Manual input and follows the tempo you tap on the button. Give about 4-8 hits for best result.
Beat/Pitch + /-
When you are holding the TAP button when you press the +/- button you can manually change the BPM in steps of 1 BPM. It's range is from 40-999 BPM.
When you are using these buttons during Loop Play they react as a pitch control, changing the playback speed of the sampler
Beat/Bank Button (1/2~4/1)
The exact function of these buttons depend on weather you are using a normal Effect or if you are using the In-Loop Sample:

Select In-Loop Sample bank. You can record 5 loops of 4 beats. The measured or tapped BPM is used to calculate the length of the loop.
Recording a Loop
When a BPM is measures (lit constantly) you can press any of the non-lit Bank buttons. Recording will start instantly and stops when it has a length of 4 beats, calculated by the measured (or tapped) BPM.
When Lit
A loop is stored and ready for playback. You cannot re-record a Loop, Erase it first.
Erase a Loop
Hold the Beat/Pitch - button while pressing any lit bank button to erase that particular bank. The light will go out. |
Used to set the tempo parameter according the beat it represents (1/2, 3/4, 1/1, 2/1 or 4/1), like on EFX-1000.
You can change this parameter as fast as you can press the buttons, it will instantly recalculate it's values.
Using the +/- buttons actually follows the same course as this row, but leaving the 3/4 measure out of it. Each press divides or multiplies the BPM by 2. |
7 Effects and In-Loop Selector
Use to select any of the effects or activate the In-Loop Sampler. The functionality of the Bank/Beat buttons will be different with this section activated.
Channel Select
Select where you want to apply effect: on the Channels 1, 2, the microphone or the master.
