Mounting the XPA Ultra Series Amplifiers The XPA Ultra Series amplifiers can be mounted in a rack using included rack ears, set on a table, mounted on a rack shelf, or mounted in the plenum space above a ceiling-mounted projector. Additionally, two XPA Ultra Series amplifiers can be connected using the included bridging plate to create a full rack-width unit.
The XPA Ultra Series amplifiers can be rack mounted using one of the following methods. Rack Ear Rack Mounting The XPA Ultra Series amplifiers ship with a set of rack ears so the half rack-width amplifiers can be installed in a full rack-width space.
