Please retain the original packing in case you should need to return the equipment to the manufacturer or supplier, or transport or ship the unit later.

Checking the mains fuse

Before installing the equipment you need to make sure that the mains fuse fitted is of the correct type and rating for your unit. To do this refer to “Replacing the mains fuse” on page 39.

Installation

This unit is designed for mounting in any 19” EIA standard rack. Four rack-mount holes in the front panel are provided for rack mounting and are designed to fully support the weight of the unit in the rack.

Note: Avoid over-tightening the rack-mount screws, as this could damage the front panel.

The position of the unit will depend upon how it is to be used. However, when positioning the unit, avoid placing it where the control knobs may be damaged by being accidentally knocked or snapped off. Also, try to avoid placing the unit directly near or on any power distribution units or power amplifiers.
