IMPORTANT SSAFETY IINSTRUCTIONS
Read these instructions.
Keep these instructions.
Heed all warnings.
Follow all instructions.
Do not use this apparatus near water.
Clean only with a dry cloth.
Do not block any ventilation openings. Ventilation should not be impeded by covering
the ventilation openings with items such as newspapers, table cloths, curtains etc.
Install in accordance with the manufacturer's instructions.
Do not install near any heat sources such as radiators, heat registers, stoves, or other
apparatus (including amplifiers) that produce heat.
Do not defeat the safety purpose of a polarised or grounding type plug. A polarised
plug has two blades with one wider than the other. A grounding type plug has two
blades and a third grounding prong. The wide blade or the third prong are provided
for your safety. If the provided plug does not fit into your outlet, consult an electri-
cian for replacement of the obsolete outlet
Protect the power cord from being walked on or pinched particularly at plugs, conve-
nience receptacles and the point where they exit from the apparatus.
Only use attachments/accessories specified by the manufacturer.
Use only with the cart, stand, tripod, bracket or table specified by the manufacturer,
or sold with the apparatus. When a cart is used, use caution when moving the
cart/apparatus combination to avoid injury from tip-over.
Unplug this apparatus during lightning storms or when unused for long periods of
time.
Refer all servicing to qualified service personnel. It is recommended that all mainte-
nance and service on the product should be carried out by Soundcraft or its autho-
rised agents. Soundcraft cannot accept any liability whatsoever for any loss or damage
caused by service, maintenance or repair by unauthorised personnel. Servicing is
required when the apparatus has been damaged in any way, such as power-supply
cord or plug is damaged, liquid has been spilled or objects fallen into the apparatus,
the apparatus has been exposed to rain or moisture, does not operate normally, or
has been dropped.
No naked flame sources, such as lighted candles, should be placed on the apparatus.
WARNING: To reduce the risk of fire or electric shock, do not expose this apparatus
to rain or moisture. Do not expose the apparatus to dripping or splashing and do not
place objects filled with liquids, such as vases, on the apparatus.

THIS APPARATUS MUST BE EARTHED. Under no circumstances should the safety
earth be disconnected from the mains lead.
The mains supply disconnect device is the mains plug. It must remain accessible so as
to be readily operable when the apparatus is in use.
If any part of the mains cord set is damaged, the complete cord set should be
replaced. The following information is for reference only.
The wires in the mains lead are coloured in accordance with the following code:
Earth (Ground): Green and Yellow (US - Green/Yellow)
Neutral: Blue (US - White)
Live (Hot): Brown (US - Black)
As the colours of the wires in the mains lead may not correspond with the coloured mark-
ings identifying the terminals in your plug, proceed as follows:
The wire which is coloured Green and Yellow must be connected to the terminal in the
plug which is marked with the letter E or by the earth symbol.
The wire which is coloured Blue must be connected to the terminal in the plug which is
marked with the letter N
The wire which is coloured Brown must be connected to the terminal in the plug which is
marked with the letter L
Ensure that these colour codes are followed carefully in the event of the plug being changed
This unit is capable of operating over a range of mains voltages as marked on the rear
panel. It is important to ensure that the correct mains fuse is fitted before switching
on the unit.

CONNECTING UUP
Before you start
Ensure the DPS-3 power supply is NOT connected to the Mains and is turned OFF.
The Power supply can be positioned anywhere within reach of the console and an available power socket, but is best rack-
mounted in a position where airflow through the vents is not obstructed and where the power switch or cables cannot be
accidentally knocked. Connect the multi-way power cable between the DPS-3 External Power Supply and the console’s con-
nector. Screw the connector locking ring clockwise on both units to secure the cable. The locking ring should be firm, but
not tight. Connect an IEC type mains cable with the plug fused at 3 AMPS, to the mains input socket on the DPS-3. Connect
the other end to the nearest plug socket and switch on the power to the DPS-3.
