UNPACKING AND INSPECTION

Your QSR synthesizer module 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 QSR for servicing.

The shipping carton should contain the following items:

•QSR with the same serial number as shown on shipping carton

•AC Power Supply

•Computer CD-ROM containing software

•This instruction manual, plus lists of Mixes and Programs, and Quick Start guide

•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 QSR works with the voltage of the country it is shipped to (either 110 or 220V, 50 or 60 Hz), and comes with a line cord or power supply suitable for the destination to which the keyboard is shipped. With the QSR off, plug the small end of the power adapter cordinto the QSR’s [POWER] socket and the male (plug) end into a source of AC power. It’s good practice to not turn the QSR on until all other cables are hooked up.

✪Alesis cannot be responsible for problems caused by using the QSR or any associated equipment with improper AC wiring.

LINE CONDITIONERS AND PROTECTORS

Although the QSR 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.
