User memo:
Listening caution
Selecting fine audio equipment such as the unit you’ve just pur-
chased is only the start of your musical enjoyment. Now it’s time to
consider how you can maximize the fun and excitement your equip-
ment 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.
We recommend you to avoid prolonged exposure to excessive
noise.
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 listening for a lifetime.

Features
Since 1997, this model has been used as the official mixer at the World DJ Championships, an event sponsored by DMC held annually 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 the SL-1200 series for oper-
ating ease.
•By providing adequate space in the panel layout around the chan-
nel 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 man-
ner 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).
•The model is equipped with [TRIM] controls (±10 dB) which com-
pensate for differences in the source level.
•The life of the cross fader has been dramatically increased by using
a photocoupler cross fader circuit.
•By reversing the input channel of the cross fader with the new cross
fader switch, you can reverse the operation of the fader.
•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 45 mm stroke faders with excellent durability and smooth op-
erating touch have been developed for this model.
•A spare channel fader has been provided on the bottom panel just
in case, and it is 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.

Note:The channel faders are designed for a long service life, but this
can be shortened if they are used in a situation that requires
rapid movement, such as during Hip-Hop transfer play. The con-
trols may need to be replaced frequently if used this way.
A spare channel fader is provided inside the bottom panel of
the unit. Refer to the additional instructions.
Consult your dealer if the cross fader ever needs replacing.
Fader replacementUse numbers indicated in parentheses when asking for replace-
ment parts.
