SETTING UP
UNPACKING AND INSPECTION
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.
AC POWER HOOKUP
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.
LINE CONDITIONERS AND PROTECTORS
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
