PRECISION 8i

OPERATION MANUAL

Mounting

The PRECISION 8i is designed for conventional rack mounting, or stand-alone mounting by use of the adhesive rubber feet supplied. Avoid locating the unit next to equipment that emits strong electromagnetic fields. If the unit is to be permanently mounted in a high-vibration environment, you may wish to provide additional side or rear support to prevent possible distortion of the mounting ears.

∙ Do not locate the unit where it is exposed to rain, moisture, or liquid spills. ∙ Do not locate the unit where it is exposed to temperature extremes.

∙ Do not mount the Power Supply Unit closer than one rack space from the preamp unit. This avoids coupling unwanted magnetic interference into the preamp unit.

Ventilation

We recommend that you provide adequate ventilation so that the air temperature surrounding the unit does not exceed 55°C (122°F). If multiple units are to be mounted in a poorly ventilated rack or travel case, a 1 3/4”blank space should be located after every two units (two units mounted together, blank space, two more units, etc.).

AC Mains Connection: Prior to connecting the AC mains power cord to the Power Supply Unit, verify that the Voltage Selector is set for the AC mains voltage in your area. The currently selected voltage appears in the window

on the Fuse Drawer 1 . It is important that the voltage is set correctly for both safety reasons and to insure that the PRECISION 8i will operate according to specifications. Note also that the correct fuse type must be used. See Table below. Product damage caused by incorrect voltage settings or fuse selections cannot be covered under warranty.
