Introduction About this User Guide This user guide contains information about the Extron series of full rack width audio power amplifiers. The Extron XTRA™ Series is a family of 1U convection cooled power amplifiers with mono, stereo, and multi-channel outputs. These professional grade amplifiers deliver from 200 to 800 watts of continuous output power and are available for low and high impedance applications.
Features Extron Patented Class D Ripple Steering (CDRS™) technology — CDRS is an Extron patented technology that provides a smooth, clean audio waveform and an improvement in signal fidelity over conventional Class D amplifier designs. CDRS eliminates the high frequency switching ripple characteristic of Class D amplifiers, a source of RF emissions, which can interfere with sensitive A/V equipment such as wireless microphones.
Installation This section discusses how to install the XTRA Series of full rack power amplifiers. WARNING: Installation and service must be performed by authorized personnel only (see UL Rack Mounting Guidelines on page 20). AVERTISSEMENT : L’installation et l’entretien doivent être effectués par le personnel autorisé...

Installing the XPA Amplifier Power off — Turn off all equipment including the XPA amplifier by toggling the power switch off and disconnecting the power cord. Verify that the amplifier is disconnected from the power source before proceeding. Mount the amplifier — For diagrams of typical application examples, see Application Examples starting on page 3.

ATTENTION: • Do not tin the wire leads before installing into the connector. Tinned wires are not as secure in the connector and could be pulled out. They may also break after being bent several times. • Ne pas étamer les conducteurs avant de les insérer dans le connecteur. Les câbles étamés ne sont pas aussi bien fixés dans le connecteur et pourraient être tirés.

Reference Information This section discusses the mounting instructions for the XPA seires of power amplifiers. Mounting the XTRA Series Power Amplifiers The XPA power amplifiers can be set on a table or mounted on a rack shelf. Tabletop Use Four self-adhesive rubber feet are included with the audio amplifier. For tabletop use, attach one foot at each corner of the bottom side of the unit and place the unit in the desired location.
Rack Mounting The XTRA series of audio amplifiers are housed in rack-mountable metal enclosures with pre-attached mounting ears for standard 19-inch racks. Mount the amplifier as follows: Disconnect all cables and power sources from the amplifier. Position the amplifier in the mounting rack so that the four slots in the mounting ears are aligned with the rack mounting holes.
