AC Power Hookup

The Wedge comes with a power adapter suitable for the voltage of the country it is
shipped to (either 110 or 220V, 50 or 60 Hz).
With the Wedge off, plug the round end of the supplied power adapter cord into
Wedge's [POWER] socket and the male (plug) end into a source of AC power. It's
good practice to not turn the Wedge on until all other cables are hooked up.
J Alesis cannot be responsible for problems caused by using the Wedge or any associated
equipment with improper AC wiring.

Line Conditioners and Protectors

Although the Wedge is designed to tolerate typical voltage variations, in today's
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 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.

Audio Connections

The connections between the Wedge and your studio are your music's lifeline, so
use only high quality cables. These should be low-capacitance shielded cables with a
stranded (not solid) internal conductor and a low-resistance shield. Although
quality cables cost more, they do make a difference. Route cables to the Wedge
correctly by observing the following precautions:
• Do not bundle audio cables with AC power cords.
• Avoid running audio cables near sources of electromagnetic interference such as
transformers, monitors, computers, etc.
