Preface

ii ENSONIQ DP/4+ Reference Manual

Power

Insert the line cord into the line

receptacle on the rear panel of the

DP/4+. Plug the other end of the

cable into a grounded AC outlet

(the proper voltage for your DP/4+

is listed on the Serial Number label

on the rear panel). Turn the DP/4+

power on and make sure the

display lights up. If not, check your

connections and power source.

When you turn the power on, the

display will show “ENSONIQ *

DP/4+,” and then go to Select mode

(Select LED on). If you travel,

remember the DP/4+ will only operate on the listed voltage.

Polarization and Grounding

Like many modern electrical devices, your ENSONIQ product has a three-prong power cord with

earth ground to ensure safe operation. Some products have power cords with only two prongs

and no earth ground. To ensure safe operation, modern products with two-prong power cords

have polarized plugs which can only be inserted into an outlet the proper way.

with earth ground

Some products, such as older guitar amplifiers, do not have polarized plugs and can be

connected to an outlet incorrectly. This may result in dangerous high voltages on the audio

connections, which could cause you physical harm or damage any properly grounded

equipment to which they are connected, such as your ENSONIQ product.

To avoid shock hazards or equipment damage, we recommend the following precautions:

• If you own equipment with two-pronged power cords, check to see if they are polarized or

non-polarized. You might consider having an authorized repair station change any non-

polarized plugs on your equipment to polarized plugs to avoid future problems.

• Exercise caution when using extension cords or plug adapters. Proper polarization should

always be maintained from the outlet to the plug. The use of polarized extension cords and

adapters is the easiest way to maintain proper polarity.

• Whenever possible, connect all products with grounded power cords to the same outlet

ground. This will ensure a common ground level to prevent equipment damage and

minimize hum in the audio output.

AC outlet testers are available from many electronic supply and hardware stores. These can be

used to check for proper polarity of outlets and cords.
