Pioneer's DJM-400 Two-Channel 96 Khz/24 Bit Mixer Offers World’s First In-Loop Sampler

Published Jan 17, 2006

Pioneer Electronics (USA) Inc. today introduced a new two-channel mixer with the world’s first in-loop sampler and provided demonstrations at the NAMM show at the Anaheim Convention Center. The new mixer matches Pioneer’s CDJ-200 CD turntable in both function and design, allowing DJs to expand the range of DJing and remixing. Its new symmetrical design is the same size as a CDJ-200 enabling an easy fit in a compact DJ coffin.

World’s First In-Loop Sampler

An intelligent 96kHz/24bit sampler automatically detects the tempo of a song during playback, sampling it for a length of 4 beats; then loops the sample. Since the sampled sound is in sync with the beat of the tune being played, no matter the tempo, it enables live remixing like never before. Samples are automatically stretched and compressed to match the beat. The DJM-400 will store five samples onboard.

“The combination of the new DJM-400 with the CDJ-200 is a great combination for pro DJs looking for a great entry-level system,” said Karl Detken, director of product planning for Pro DJ products at Pioneer Electronics (USA) Inc. “It offers the reliability, a wide range of features, and the high quality audio for which Pioneer products are known.”

Onboard Effects and Equalization

Onboard effects automatically detect the beats per minute of the music and sync to the beats. The DJM-400 includes seven onboard effects: Delay, Echo, Filter, Flanger, Phaser, Robot and Roll. All effects are processed at 24bits for the highest quality sound. A new Beat Select button allows more intuitive and aggressive DJ playing and remixing.

Each channel has a 3-band isolator EQ with full cut capability. The EQ ranges from +9dB to -∞ (infinity) for total control of the sound.

The DJM-400 offers a number of key features for a professional DJ, including:

- The ability to select either of two microphone connections or one stereo line connection;

- A fader start so playback can be started by simply sliding the cross fader or channel fader when connected to a Pioneer CDJ product;

- A peak level meter so the DJ can check audio input levels for each channel or for the master;

- A Talk Over feature that automatically lowers track volume for the DJ to speak over the track.


The DJM-400 will be available March 2006 for a manufacturer’s suggested retail price of $699.

Pioneer offers a complete line of Pro DJ Equipment through its Pro Audio Group. Its DJM series of mixers have become an industry standard at clubs, studios, mobile rigs and homes around the world, known for their high quality sound and reliability. For more information, visit
