SETUP & CONNECTIONS

AC POWER

HOOKUP

Your QS7.1/QS8.1 is set to work with the voltage of the country to which it was shipped (either 110 or 220V, 50 or 60 Hz) and comes equipped with the appropriate power cable.

Hooking that cable up is simple.

∙Make sure your QS is turned off.

∙Plug the female (jack) end of the power cable into the QS’s power socket.

∙Plug the male (plug) end into a source of AC power. It’s good practice not to turn the QS on until all other cables are hooked up.

The IEC-spec power cable included with your QS is designed to connect to an outlet with three holes, the third of which — the round one — is the ground connection. This connection is an important safety feature: it keeps the QS’s chassis at ground potential, preventing accidental shocks.

Unfortunately, not all three-hole sockets are properly grounded. We recommend that you use an AC line tester to check the ground connection on any socket you may use, just to be on the safe side. If you find an ungrounded outlet, consult with a licensed electrician about getting the problem fixed.

✪Avoid using ungrounded outlets. Plugging the QS into an ungrounded outlet can be hazardous. The same goes for “lifting” the unit off ground by using a three-to-two plug adapter. Don’t do it!

✪Alesis cannot be responsible for any problems that might be caused by using the QS with improper AC wiring.

LINE CONDITIONERS AND PROTECTORS

The power coming through some AC lines contains voltage surges, spikes, or transients that can stress your gear, causing failure or malfunctions. Although the QS is designed to tolerate typical voltage variations, it isn’t invulnerable. So if the power in your area is particularly bad (or if you are out playing live gigs) you will probably want to take precautions. You have three basic options:

•Line spike/surge protectors. These relatively inexpensive devices are designed to protect against strong surges and spikes. They act somewhat like fuses and will have to be either replaced or reset (depending on the unit) if they’ve been hit by an extremely strong spike.
