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
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.
