CHAPTER 1

SETTING UP

Unpacking and Inspection

Your Q20 was packed carefully at the factory, and 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 Q20 for servicing.

The shipping carton should contain the following items:

¥ This instruction manual

¥ Alesis Q20 with the same serial number as shown on shipping carton

¥ AC Power Cable

¥ Alesis warranty card

¥ Quick Reference Guide

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 Q20 includes an internal universal power supply which is compatible with any

line voltage from 90-265 VAC, 50-60 Hz. It also includes a removable IEC power

cable suitable for use in the country shipped to.

Note that the Q20 uses a soft power switch which will turn the unit on when

plugged in. It is good practice to turn your mixer inputs or returns down while

connecting the Q20.

Alesis cannot be responsible for problems caused by using the Q20 or any associated

equipment with improper AC wiring.

Line Conditioners and Protectors

Although the Q20 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.
