OPERATING ENVIRONMENT

THERMAL CONSIDERATIONS IN RACK MOUNTING

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

•Always allow adequate ventilation behind the XT . Do not seal any enclosure that holds the XT . It is not necessary to leave an empty rack space above or below the XT unless it runs hot enough to affect equipment above or below it.

•You will need to remove the screw-on feet from the bottom of the XT if any equipment will be mounted directly below it.

MOUNTING ON A SHELF OR NON-RACK ENCLOSURE

To mount the XT on a shelf or other flat surface, Alesis recommends using the attached screw-on feet to avoid scratching the shelf’s surface with the deck’s bottom. Please observe the general comments on thermal considerations given under “Thermal Considerations in Rack Mounting” no matter where or how the deck is mounted.

AVOIDING ELECTROMAGNETIC INTERFERENCE

Like all tape machines, the XT uses magnetic tape that can be sensitive to electromagnetic interference. Generally this is not a problem, but avoid mounting the XT next to devices that generate strong magnetic fields such as power amplifiers, monitors and video display devices, speakers, etc.
