Page 7: Introduction
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. -
Page 8: Features
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. -

Page 12: Installing The Xpa Amplifier
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. - Page 13 4-pole (8 ohm or 4 ohm) output connector wiring: Do not tin the wires! Figure 8. Wiring 4-pole Connectors ATTENTION: • Do not short the + and outputs to each other. Doing so may damage the amplifier. • Ne pas créer un court circuit entre les sorties + et au risque d’endommager l’amplificateur.

- Page 19 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.
