NSPECTION
Your DM5 was packed carefully at the factory. The shipping carton was designed to
protect the unit during shipping. Please retain this container in the highly unlikely
event that you need to return the DM5 for servicing.
The shipping carton should contain the following items:
DM5 with the same serial number as shown on shipping carton
AC Power Supply Adapter
This instruction manual
Alesis warranty card
It is important to register your purchase; if you have not already filled out your warranty
card and mailed it back to Alesis, please take the time to do so now.

OOKUP
The DM5 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 DM5 off, plug the small end of
the power adapter cord into the DM5’s [POWER] socket and the male (plug) end into
a source of AC power. It’s good practice to not turn the DM5 on until all other cables
are hooked up.
Alesis cannot be responsible for problems caused by using the DM5 or any associated
equipment with improper AC wiring.

ONDITIONERS AND

ROTECTORS
Although the DM5 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.
