Setting Up
8 QuadraSynth Reference Manual
Do not operate any electrical equipment with ungrounded outlets. Plugging the
QuadraSynth into an ungrounded outlet, or ÒliftingÓ the unit off ground with a three-to-two
wire adapter, can create a hazardous condition.
Alesis cannot be responsible for problems caused by using the QuadraSynth or any associated
equipment with improper AC wiring.
Line Conditioners and Protectors
Although the QuadraSynth is designed to tolerate typical voltage variations, in
todayÕs world the voltage coming from the AC line may contain spikes or transients
that can possibly stress your gear and, over time, cause a failure. There are three
main ways to protect against this, listed in ascending order of cost and complexity:
¥ Line spike/surge protectors. Relatively inexpensive, these are designed to
protect against strong surges and spikes, acting somewhat like fuses in that they
need to be replaced if theyÕve been hit by an extremely strong spike.
¥ Line filters. These generally combine spike/surge protection with filters that
remove some line noise (dimmer hash, transients from other appliances, etc.).
¥ Uninterruptible power supply (UPS). This is the most sophisticated option. A
UPS provides power even if the AC power line fails completely. Intended for
computer applications, a UPS allows you to complete an orderly shutdown of a
computer system in the event of a power outage, and the isolation it provides
from the power line minimizes all forms of interferenceÑspikes, noise, etc.
