Use a commercially available 100BASE-TX-compatible switching hub. Depending on the switching hub, the unit may not operate properly.

LAN terminal specifications conform to 100BASE-TX standards.
Use a commercially available category 5 class LAN cable or better. Depending on the LAN cable, the unit may not operate properly.

Also, when connecting with a Pioneer DJ player, we recommend using the LAN cable included with the Pioneer DJ player. Note that this unit's LAN terminal has a Pioneer-specific interface, so LAN connections to other brands of DJ players are not possible.

-When controls and buttons on this unit are operated, the corresponding MIDI signals are output to the computer via the USB cable. (See the operating instructions for details.)
-Signal assignments cannot be changed on this unit.
-This unit does not support input of MIDI signals.

This unit can convert the tempo information (BPM) into MIDI timing clocks and send this to the EFX-1000. Also, the EFX-1000 is equipped with a mode for applying effects in sync with the MIDI timing clocks input from external devices. By using these functions together, effects applied with the EFX-1000 can be operated with the tempo displayed on this unit's BPM counter.

The audio for the position selected with the effect channel selector switch in the BEAT EFFECT section (pre-channel fader audio, microphone audio, post-crossfader A or B audio, or master audio) is output to the external device through the SEND terminal. After this, the sound processed on the external device returns to the selected position through the RETURN terminal. The meanings of the selector switch positions are described below. For details, see "Block Diagram" in the operating instructions.

1-4
Pre-faders for the respective channels (stage before channel faders)

MIC
Stage after MIC EQ and MIC volume

CF.A/CF.B
Post-crossfader A or B (stage after crossfader A or B)

Master audio
Stage before master volume

The sound is the same, but it is not affected by the master volume setting.

The fader start function can be used when this unit is connected to a CDJ by PRO DJ LINK. Use this unit in combination with a CDJ-2000nexus, CJD-2000 or CDJ-900 supporting the PRO DJ LINK function. To use the PRO DJ LINK function, update the CDJ’s firmware to the latest version. The latest firmware is available on the Pioneer support page.
This unit does not support connection with a control cord.

With this unit, the PCM audio signals can be input. Dolby Digital and DTS audio signals cannot be input.

The digital input specifications are as follows:

Input format: S/PDIF
Sampling frequency: 28 kHz to 96 kHz
Sampling bits: 16/20/24 bits

Yes. Connect audio cables to input audio signals from the CDJ to the mixer.

Either EFX can be connected, but the EFX-1000 offers higher sound quality and more functions. This unit does not support EFX LINK, so connect it to the EFX-1000 using a cord with a phone plug (ø6.3 mm).

This unit measures 331 mm in width, while the DJM-800 measures 320 mm.
You may be able to use DJM-800's flight case by rearranging its inner cushion.
However, please note that use of the DJM-800's flight case is not guaranteed by Pioneer DJ.

If this unit is connected after launching the DJ software, the DJ software may not recognize this unit. Launch the DJ software after connecting this unit.

Use a turntable (analog player) that can play analog records or a CDJ player that can play music CDs (CD-DA format). In both cases, check that the player is equipped with audio output terminals.

This unit is equipped with two sets of MASTER outputs (audio outputs).
The sound can be output to speakers via an external amplifier by connecting these audio outputs to the external inputs of a regular amplifier, mini-component or powered speakers. Connect this unit's MASTER1 output terminals to the amplifier's XLR inputs, the MASTER2 output terminals to the amplifier's RCA inputs.

Performance is not guaranteed via a converter cable (converter plug).
Connect the MASTER1 and BOOTH output terminals to an amplifier with XLR inputs, the MASTER2 output terminals to an amplifier with RCA inputs.

The following terminals support balanced type inputs/outputs:

-MASTER1 output terminals (XLR)
-BOOTH output terminal (TRS)
-MIC input terminal (XLR/TRS)

It is a balanced terminal.
For its polarities as seen from the front of the terminal, see the diagram.

No.

Stereo microphones are not supported. Use a monaural microphone.

Yes.
Stereo and monaural phone jacks can be connected.

TIP = HOT, RING = COLD, SLEEVE = GND

This slot is for mounting a theft-prevention wire lock.

Pioneer does not sell a rack mount kit specifically for this unit (as of July 2011). If you are considering mounting it on a rack, you should consult a rack building specialist, etc.

Driver software is the software allowing this unit to be connected to a computer.
The driver software can be acquired from the Pioneer DJ support page.

It can be acquired from the download page.

Yes. Refer to “Installing the software” on page 5 of the operating instructions and install the driver software.

This unit cannot be used via a USB hub. Connect it directly to a computer using the included USB cable..

The [MASTER OUT 1] terminals are balanced output terminals. Use XLR connectors.

An Internet connection environment is necessary to download the Serato DJ software and to upgrade it to the latest version.

To scratch using a control CD or control vinyl with Serato DJ, you will need to prepare a player for playing the control CD or control vinyl, a computer on which Serato DJ is installed, as well as powered speakers (or an amplifier and speakers) for outputting the sound and headphones. Also, by adding a DDJ-SP1 DJ controller, you can achieve dynamic, individualistic DJ performances.

This unit cannot be used on USB bus power. Connect the included AC adapter when using it.
