2.0 Setup

2.1 Unpacking Your Amplifier

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 shipping damage. We 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 materials so you will have them if you 

ever need to transport the unit. Never ship the unit without the factory pack.

WARNING:

 Before you start to set up your amplifier, make sure you read and 

observe the Important Safety Instructions found at the beginning of this manual.

2.2 Installing Your Amplifier

CAUTION:

 Before you begin, make sure your amplifier is disconnected from the 

power source and all level controls turned completely down (counterclockwise).

Note:

 We recommend that any sensitive equipment be located at least 8 inches (20 

cm) away from the amplifier.

To install the amplifier, you can use one of the following approaches:

•  Rack mount the amplifier with the rack mounting kit, see Figure 2.2.2.
•  Place a single amplifier on a surface with 12 inches of air space around  

the unit for convection cooling. Rubber feet are included and can be  

attached onto the underside of the chassis. For amplifier dimensions,  

see Figure 2.2.1.
