LINE CONDITIONERS AND PROTECTORS
Although the LX20 can tolerate typical voltage variations, the AC line voltage
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 they’ve 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 interference — spikes, noise, etc.
If your AC power is unstable or subject to occasional browns-outs or interruptions, use
a professional power conditioner or uninterruptible power supply. Some people who
have experienced problems with ADAT operation have had those problems
disappear completely after installing proper power conditioning.
