XLS Series Power Amplifiers 1 Welcome The XLS Series of power amplifiers from Crown represents a new era in affordable, quality power amplification. The line consists of three models in a uniform, rugged chassis, incorporating the best of tried-andtrue design principles and innovative features. Modern power amplifiers are sophisticated pieces of engineering capable of producing extremely high power levels.
XLS Series Power Amplifiers 3 Setup 3.1 Unpack Your Amplifier 3.3 Mount Your Amplifier 3.4 Ensure Proper Cooling YOU WILL NEED (not supplied): CAUTION: Before you begin, make sure your amplifier is disconnected from the power source, with power switch in the “off” position and all level controls turned completely down (counterclockwise). When using an equipment rack, mount units directly on top of each other. Close any open spaces in rack with blank panels. DO NOT block side or front air vents.
XLS Series Power Amplifiers 3 Setup 3.5 Choose Input Wire and Connectors 3.6 Choose Output Wire and Connectors Crown recommends using pre-built or professionally wired, balanced line (two-conductor plus shield), 22-24 gauge cables and connectors. You should use 3-pin male XLR cable ends at the amplifier inputs. Unbalanced line may also be used but may result in noise over long cable runs.
XLS Series Power Amplifiers 3 Setup 3.7 Wire Your System 3.7.1 Stereo Mode Typical input and output wiring is shown in Figure 3.6. INPUTS: Connect input wiring for both channels. OUTPUTS: Maintain proper polarity (+/-) on output connectors. 3.7.2 Bridge-Mono Mode 120V 110V Connect Channel 1 positive (+) speaker load to Channel 1 positive (red) terminal of amp; repeat for negative (-). Repeat Channel 2 wiring as for Channel 1. Figure 3.6.
