Rack Mounting

The XPA U 1004 SB and XPA U 2002 SB can both be mounted onto a rack using one of 

the following methods.

Rack Ear Mounting

The XPA U 1004 SB and XPA U 2002 SB ship with a set of rack ears, so that the half rack-

width amplifiers can be installed in a full rack-width space. 

Mount the amplifier with the rack ears by doing the following:

1. 

Remove the rubber feet from the bottom of the amplifier if previously installed.

2. 

Attach the included rack ears to the sides of the amplifier with the four provided #6 

machines screws (

3. 

Insert the amplifier into the rack and align the holes in the rack ear with the holes on the 
rack.

4. 

Secure the amplifier to the rack using four provided 10-32 x 3/4” screws (see figure 2,

Bridge Plate Rack Mounting

The XPA U 1004 SB and XPA U 2002 SB ships with a bridge plate connector to allow two 

amplifiers to be connected together and form a full rack-width unit. 

Mount two XPA Ultra Series amplifiers by doing the following:

1. 

If the rubber feet are installed on the bottom of the amplifier, remove them.

2. 

Position two amplifiers upside down and next to each other.

3. 

Use the bridge plate connector and the four provided #4 machine screws to connect 
the two amplifiers together (see figure 3, 

1

).

4. 

Attach the two short rack ears to the amplifiers with four provided #6 machine screws 

(
