Please unpack and inspect your amplifier for any damage that may have occurred during transit. If damage is found, notify the transportation company immediately. Only you can initiate a claim for ship- ping damage. Crown will be happy to help as needed. Save the shipping carton as evidence of damage for the shipper’s inspection.
We also recommend that you save all packing mate- rials so you will have them if you ever need to trans- port the unit. Never ship the unit without the factory pack.
YOU WILL NEED (not supplied):
•Input wiring cables
•Output wiring cables
Rack for mounting amplifier (or a stable surface for stacking)
WARNING: Before you start to set up your amplifier, make sure you read and observe the Important Safety Instructions at the beginning of this manual.
CAUTION: Before you begin, make sure your amplifier is disconnected from the power source, with power switch in the “off” posi- tion and all level controls turned completely down (counterclockwise).

You may also stack amps without using a cabinet.
NOTE: When transporting, amplifiers should be supported at both front and back.
When using an equipment rack, mount units directly on top of each other. Close any open spaces in rack with blank panels. DO NOT block front or rear air vents. The side walls of the rack should be a minimum of 2 inches (5.1 cm) away from the ampli- fier sides, and the back of the rack should be a min- imum of 4 inches (10.2 cm) from the amplifier back panel.
