Insert the line cord into the line receptacle on the back of the ASR-10 (2), next to the power switch
(1). Plug the other end of the cable into a grounded AC outlet. The proper voltage for your ASR-
10 is listed on the Serial Number label on the rear panel. Turn the ASR-10 power on and make
sure the display lights up. If not, check your connections and power source.
Power — Polarization and Grounding
Like many modern electrical devices, your ASR-10 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 that can only be inserted into an outlet the proper way. 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 that 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.
