Unpacking and Inspection

Your PEQ-450 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 PEQ-450 for servicing.

The shipping carton should contain the following items:

•PEQ-450 with the same serial number as shown on shipping carton

•Power Cable

•This instruction manual

Installing in a Rack

The PEQ-450 may be simply set on a table, or installed in a standard 19" audio equipment rack. The rack ears are integral to the unit.

Thermal Considerations in Rack Mounting

The PEQ-450 can be mounted in an equipment rack (taking up 3 rack spaces) or placed on a table or shelf. When you install it, keep in mind that heat is the major enemy of electronic equipment. Please observe the following:

•The PEQ-450 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 PEQ-450 will meet its published specs or remain reliable if operated outside of these ranges.

•Always allow adequate ventilation behind the PEQ-450. Do not seal any enclosure that holds the PEQ-450. It is not necessary to leave an empty rack space above or below the PEQ-450 unless it runs hot enough to affect equipment above or below it. If your environment is unusually warm and not air conditioned, space between units will help the units run cooler.
