Alesis ALESIS M20 owner manual Operating Environment, Avoid Electromagnetic Interference

Chapter 1, Overview, Setup and Basics

1.11OPERATING ENVIRONMENT

Mount the M20 in an equipment rack (requires 4 rack spaces) or place it on a table or shelf. Alesis advises against tilting the recorder; keep it horizontal. Also remember that heat shortens the life of electronic equipment.

Please observe the following:

∙The M20 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 M20 will meet its published specs or remain reliable if operated outside of these ranges.

∙Always allow adequate ventilation behind the M20. Do not seal any enclosure that holds the M20. It is not necessary to leave an empty rack space above or below the M20.

∙You will need to remove the screw-on feet from the bottom of the M20 if any equipment will be mounted directly below it.

1.12AVOID ELECTROMAGNETIC INTERFERENCE

Like all tape machines, the M20 uses magnetic tape that can be sensitive to electromagnetic interference. Generally this is not a problem, but avoid mounting the M20 next to devices that generate strong magnetic fields such as power amplifiers, monitors and video display devices, speakers, etc., and always treat your tapes with care. In particular, avoid excess heat, cold, and humidity.
