Unpacking and Inspection

Your DEQ230 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 DEQ230 for servicing.

The shipping carton should contain the following items:

•DEQ230 with the same serial number as shown on shipping carton

•A/C power supply adapter (DEQ230 only)

•A/C power cable (DEQ230D only)

•This instruction manual

Installing in a Rack

The DEQ230 may be simply set on a table, or installed in a standard 19" audio equipment rack.

Thermal Considerations in Rack

Mounting

The DEQ230 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 DEQ230 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 DEQ230 will meet its published specs or remain reliable if operated outside of these ranges.

•Always allow adequate ventilation behind the DEQ230. Do not seal any enclosure that holds this unit. It is not necessary to leave an empty rack space above or below the DEQ230. However, if your environment is unusually warm and not air conditioned, space between units will help the units run cooler.
