  • Is an output LC filter required?
    • Based on the application a simple filter (i.e. ferrite beads, ceramic capacitor) can be used. For example, active speakers used for compact LCDs or iPod docks are products that use short speaker cables, while large-screen LCDs require longer speaker cables, resulting in the generation of unwanted radiation (EMI) requiring countermeasures (i.e. filters).

  • What is BTL output method?
    • It is the abbreviation of Bridge Tied Load.
      It reverses the speaker both terminals to connect by using two amplifier circuits compared with a usual single amplifier. If without output coupling capacitor,it may has an advantage that output electric power quadruples.
