Description

The TI Analog Crossover Audio Plug-in Module (SIDEGIG-XOVEREVM) turns TI Audio Class-D amplifier EVM’s into a high quality, two-way speaker amplifier. The plug-in module makes it easy to remove thelarge and expensive passive crossover found in passive loudspeakers and create a bi-amped,two-way system with improved efficiency and reduced size. The board features a tunable active crossover with ahigh-pass filter,low-pass filter,baffle step, and delay to create two audio output signals for a tweeter and woofer. There are many advantages of designing active speakers including well-matched and well-tunedaudio. This audio plug-in module plugs into an analog input Class-D audio evaluation module (EVM) with an audio interface board (AIB) connector. This document provides information including setup,operation, schematics,bill of materials (BOM) and printed-circuit board (PCB) layout.
