Unpacking and Inspection

Your DEQ830 was packed carefully at the factory. The shipping carton was designed to protect the unit during transit. Please keep this carton in the highly unlikely event that you need to return the DEQ830 for servicing.

The shipping carton should contain the following items:

DEQ830 with the same serial number as shown on the shipping carton

AC power cable

Installing in a Rack

The DEQ830 may be simply set on a table, or installed in a standard 19" audio equipment rack.

Thermal Considerations in Rack

Mounting

The DEQ830 can be mounted in an equipment rack (occupying one rack space) or placed on a table or shelf. When you install it, keep in mind that heat is the greatest enemy of electronic equipment. Please observe the following:

The DEQ830 is designed to perform properly over a range of ambient temperatures from 10° C to +40° C (50° F to 104° F), in up to 80% non-condensing humidity. These are not absolute limits, but Alesis cannot guarantee that the DEQ830 will meet its published specs or remain reliable if operated outside of these ranges.

Always allow adequate ventilation behind the DEQ830. Do not seal any enclosure that holds this unit. It is not necessary to leave an empty rack space above or below the DEQ830. However, if your environment is unusually warm and not air conditioned, space between units will help the units run cooler.
