Roland S-4000-SP User Manual
Owner’s Manual
Main Features
The S-4000-SP is a REAC splitter for use with the RSS S-4000 Digital Snake System.
Use of this REAC splitter enables you to do the following:
• It permits you to extend REAC cables in lengths of 100 meters.
• It allows you to split the master REAC device’s input audio to a split REAC device.
In addition, the S-4000-SP also has the following features:
• The S-4000-SP is made up of two independent 5 port splitters with independent
power supplies. These two splitters can be used independently as dedicated
splitters for the REAC device’s MAIN port and BACKUP port. This provides a fully
redundant REAC connection system.
• Two independent internal power supplies furnish power to each of the two internal
splitters, enabling uninterrupted use in the event the power happens to cut out in
one of the power supplies or if there is some other sort of power interruption.

all servicing to your dealer, the nearest Roland
Service Center, or an authorized Roland
distributor, as listed on the “Information” page.
..........................................................................................................
004
• Never use or store the unit in places that are:
• Subject to temperature extremes (e.g., direct
sunlight in an enclosed vehicle, near a heating
duct, on top of heat-generating equipment); or
are
• Damp (e.g., baths, washrooms, on wet floors);
or are
• Humid; or are
• Exposed to rain; or are
• Dusty; or are
• Subject to high levels of vibration.
..........................................................................................................
007
• Make sure you always have the unit placed so it is
level and sure to remain stable. Never place it on
stands that could wobble, or on inclined surfaces.
..........................................................................................................
008a
• The unit should be connected to a power supply
only of the type described in the operating
instructions, or as marked on the rear side of unit.
..........................................................................................................
008e
• Use only the attached power-supply cord. Also,
the supplied power cord must not be used with
any other device.
..........................................................................................................
009
• Do not excessively twist or bend the power cord,
nor place heavy objects on it. Doing so can
damage the cord, producing severed elements
and short circuits. Damaged cords are fire and
shock hazards!
..........................................................................................................
011
• Do not allow any objects (e.g., flammable
material, coins, pins); or liquids of any kind
(water, soft drinks, etc.) to penetrate the unit.
..........................................................................................................
012a
• Immediately turn the power off, remove the
power cord from the outlet, and request servicing
by your dealer, the nearest Roland Service Center,
or an authorized Roland distributor, as listed on
the “Information” page when:
• The power-supply cord, or the plug has been

015
• Do not force the unit’s power-supply cord to
share an outlet with an unreasonable number of
other devices. Be especially careful when using
extension cords—the total power used by all
devices you have connected to the extension
cord’s outlet must never exceed the power rating
(watts/amperes) for the extension cord. Excessive
loads can cause the insulation on the cord to heat
up and eventually melt through.

reception. Do not use this device in the vicinity of such
receivers.
352b
• Noise may be produced if wireless communications
devices, such as cell phones, are operated in the vicinity of
this unit. Such noise could occur when receiving or
initiating a call, or while conversing. Should you
experience such problems, you should relocate such
wireless devices so they are at a greater distance from this
unit, or switch them off.
355b
• When moved from one location to another where the

or malfunction may result if you attempt to use the unit in
this condition. Therefore, before using the unit, you must
allow it to stand for several hours, until the condensation
has completely evaporated.
360
• Depending on the material and temperature of the surface
on which you place the unit, its rubber feet may discolor
or mar the surface.

to prevent this from happening. If you do so, please make
sure that the unit will not slip or move accidentally.
Maintenance
401a
• For everyday cleaning wipe the unit with a soft, dry cloth
or one that has been slightly dampened with water. To
remove stubborn dirt, use a cloth impregnated with a
mild, non-abrasive detergent. Afterwards, be sure to wipe
the unit thoroughly with a soft, dry cloth.
