ENSONIQ Avista 7600 User’s Guide
25
Some products 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.

We recommend observing 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 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.
AC Line Conditioning
As with any computer device, the Avista 7600 is sensitive to sharp peaks
and drops in the AC line voltage. Lightning strikes, power drops, or
sudden and erratic surges in the AC line voltage can scramble the
internal memory, and in some cases, damage the unit’s hardware. Here
are a few suggestions to help guard against such occurrences:
•
A surge/spike suppressor. A surge/spike suppresser absorbs
surges and protects your gear from all but the most severe over-
voltage conditions. You can purchase multi-outlet power strips
with built-in surge/spike suppressers.
•
A line conditioner. This is the best, although more expensive, way
to protect your gear. In addition to protecting against surges and
spikes, a line conditioner guards the equipment against excessively
high or low line voltages. If you use the Avista 7600 in lots of
different locations with varying or unknown AC line conditions,
you might consider investing in a line conditioner.
