Placement

Avoid placing the unit in areas of:

• direct sunlight
  high temperature
  high humidity
  excessive vibration
• uneven surfaces (Place the unit on a flat level surface.)

Such conditions might damage the cabinet and/or other component parts and thereby shorten the unit's service life.

To protect the unit against sound distortion and acoustical effects, please place the unit at least 15 cm away from wall surfaces etc.

Stacking

Never place heavy items on top of the unit or the AC mains lead.

Voltage

• It is very dangerous to use an AC power source of high voltage such as for an air conditioner.
  A fire might be caused by such a connection.
• A DC power source can not be used.
  Be sure to check the power source carefully, especially if on a ship or other place where DC is used.

AC mains lead protection

• Avoid cuts, scratches or poor connection of the AC mains lead, as this may result in fire or electric shock.
  Excessive bending, pulling or slicing of the AC mains lead should also be avoided.
• Do not pull on the AC mains lead when you are disconnecting the power, as this could cause an electric shock. Grasp the plug firmly when you disconnect the AC mains lead.
• Never touch the plug with wet hands or a serious electric shock could result.

Foreign materials

• Ensure that no foreign objects, such as needles, coins, screwdrivers etc., accidentally fall into the unit.
  Otherwise, a serious electric shock or malfunction could occur.
• Be extremely careful about spilling water or liquid on/into the unit, as a fire or electric shock could occur.
  (Disconnect the power plug and contact your dealer immediately if this occurs.)
• Avoid spraying insecticides onto the unit as they contain flammable gases which can be ignited.
• Insecticides, alcohol, paint thinner and similar chemicals should never be used to clean the unit as they can cause flaking or cloudiness to the cabinet finish.

Service

• Never attempt to repair, disassemble or reconstruct the unit if there seems to be a problem.
  A serious electric shock could result if you ignore this precautionary measure.
• If a problem occurs during operation (the sound is interrupted, indicators fail to light up, smoke is detected, etc.) contact your dealer or Authorized Service Center immediately.
• Disconnect the power supply if the unit will not be used for a long time. Otherwise the operation life could be shortened.

CAUTION!

DO NOT INSTALL OR PLACE THIS UNIT IN A BOOKCASE, BUILT IN CABINET OR IN ANOTHER CONFINED SPACE. ENSURE THE UNIT IS WELL VENTILATED. ENSURE THAT CURTAINS AND ANY OTHER MATERIALS DO NOT OBSTRUCT THE VENTILATION TO PREVENT RISK OF ELECTRIC SHOCK OR FIRE HAZARD DUE TO OVERHEATING.

Insertion of connector

Even when the connector is perfectly inserted, depending on the type of inlet used, the front part of the connector may jut out as shown in the drawing.

However there is no problem using the unit.

This model is the official audio mixer for the DMC-sponsored World DJ Championship, an event held annually since 1997 that brings together professional disc jockeys from all over the world. It is a top-of-the-line audio mixer with the kind of outstanding design, functions, and sound quality that suits the requirements of disc jockeys accustomed to giving scratch-mixing performances in a variety of ways.

Operating ease

• This audio mixer is the same height as SL-1200M3D for operating ease.
• By providing adequate space in the panel layout around the channel faders and cross fader and by eliminating protruding parts, full rein can be given to individual technique which exactly reflects the mood of the moment even when it comes to high-powered scratch-mixing.

Functions

• The model comes with both high and low equalizers so that all manner of sound sources can be accommodated to generate a highly creative style of sound. A wide margin of creativity in producing sound is provided since the attenuation is set to a high -24 dB (12 dB/oct).

Equalization characteristics

• The model is equipped with [TRIM] controls (±10 dB) which compensate for differences in the source level.
• By adding a pre-fader monitor, the channels selected by [MONITOR CUE] controls can be monitored regardless of the positions of the faders.

It is also possible to mix and monitor the line-out sources.

• The model comes with line-out connectors for monitoring so that sound can be monitored not only with headphones but through the speakers inside the booth.
• The line-out source L and R levels as well as the monitor source levels can be checked out on the 12-point, 3-column level meter.
• An [AUX IN] connector is provided to enable a sampler, keyboard, etc. to become part of the disc jockey scene.

Construction and materials

• New 45mm stroke faders with an excellent durability and smooth operating touch have been developed for this model. The service life of the channel faders and cross fader has been improved by a quantum leap.
• A spare channel fader and a spare cross fader have been provided on the bottom panel just in case, and the faders themselves are designed to enable easy replacement.
• Lever switches are employed for the input selector controls (LINE, PHONO) and, by providing adequate space around them, they can also be used for operations involving transformer scratching.
