WE WANT YOU TO LISTEN FOR A LIFETIME
Selecting fine audio equipment such as the unit you’ve just purchased is only the start of your musical enjoyment. Now it’s time to consider
how you can maximize the fun and excitement your equipment offers.
This manufacturer and the Electronic Industries Association’s Consumer Electronics Group want you to get the most out of your equipment by playing it at a safe level. One that lets the sound come through loud and clear without annoying blaring or distortion—and, most importantly, without affecting your sensitive hearing. Sound can be deceiving. Over time your hearing “comfort level” adapts to higher volumes of sound. So what sounds “normal” can actually be loud and harmful to your hearing. Guard against this by setting your equipment at a safe level BEFORE your hearing adapts.
To establish a safe level, start your volume control at a low setting.
Slowly increase the sound until you can hear it comfortably and clearly, and without distortion. Once you have established a comfortable sound level, set the dial and leave it there. Taking a minute to do this now will help to prevent hearing damage or loss in the future. After all, we want you to listen for a lifetime.
Used wisely, your new sound equipment will provide a lifetime of fun and enjoyment. Since hearing damage from loud noise is often undetectable until it is too late, this manufacturer and the Electronic Industries Association’s Consumer Electronics Group recommend you avoid prolonged exposure to excessive noise. This list of sound levels is included for your protection.

DECIBEL LEVEL EXAMPLE
30 – Quiet library, soft whispers
40 – Living room, refrigerator, bedroom away from traffic
50 – Light traffic, normal conversation, quiet office
60 – Air conditioner at 20 feet, sewing machine
70 – Vacuum cleaner, hairdryer, noisy restaurant
80 – Average city traffic, alarm clock at two feet.
THESE NOISES CAN BE DANGEROUS UNDER CONSTANT EXPOSURE
90 – Subway, motorcycle, truck traffic, lawnmower
100 – Garbage truck, chain saw, pneumatic drill
120 – Rock band concert in front of speakers, thunderclap
140 – Gunshot blast, jet plane
180 – A rocket launching pad

CLEANING THE UNIT
To clean the MDJ-600, use only a dry soft cloth and/or compressed air. If the unit is soiled with stubborn dirt, we suggest using a 2:1 solution of distilled water and 30% isopropyl alcohol. Avoid using harsh cleaning chemicals such as benzene, paint thinner, bleach, or hydrochloric acid, which will damage the unit

OPERATING CONDITIONS
For optimum performance, the temperature of the operating environment should be between +5º C to +35º C (+41º F – +95º F). Failure to maintain proper operating temperature may result in difficulty reading the display, thermal overload, or system-wide
instability. Avoid exposing the unit to direct sunlight.
When placing the unit in an installation, make sure that it is placed on a stable surface, as far away from vibrations as possible. Even though the unit is impervious to vibration, the storage devices (specifically hard-drive-based devices) that are designed to be used in conjunction with it are typically not. Also be sure not to place or use the player on the heat-generating sources, such as amplifiers or near spotlights.

It is possible that you will need to change the MIDI channel your MDJ-600 is using – either to gain compatibility with software or to resolve a conﬂict with another connected MIDI device.
To change the MIDI channel, make sure that you have the USB source selected, then press SETTINGS (9). Scroll down to the entry called MIDI CHANNEL. Press the browse knob to select that entry, then turn the browse knob to select the desired channel (0-15 are available). Once you’ve selected the correct MIDI channel, press the BACK button to exit Settings.
NOTE : In Settings, the MIDI channels are presented in hexadecimal. If your software defines the MIDI channel in decimal, just add 1 (so if Settings says channel “0” is selected, that is channel “1”, and so on).

After configuring the MIDI settings on the MDJ-600, start the DJ software:

Select the MDJ-600 as your MIDI device*
Select the MDJ-600 as your AUDIO device
Refer to DJ software’s instructions

24-bit/192kHz

24-bit/48 kHz
16-bit/48kHz
16-bit/44.1 kHz

To change these settings, press the USB source select button (26), and then press the SETTINGS button (9). Scroll down to the SOUND CARD entry, press the browse knob to select, turn to select one of the available options, and press the browse knob again to activate that setting.
NOTE: Higher bit depth and sampling rates will create greater latency and may impact performance.

Settings are stored and loaded from the USB storage device when one is connected. To manually set or recall your settings, use the “Load Settings from MSD” or “Save Settings to MSD” features from your settings page in the MDJ-600. The Gemini VCASE software can also create and set settings data. This allows you to configure one device the way you want it, then export those settings to your other MDJ devices.
