FiX-LSA-4 Load Sensing Adaptor

The FiX-LSA-4 4-channel load sensing adapter fixes a common problem that some factory amplifiers have when working with the FiX-82. When it connects to the amp, the audio mutes. Why? Some factory amps have a load detection circuit that is looking for a low-impedance load to use the audio output. The FiX-82 has a high-impedance load at the input section. So when it connects to the factory amp, the audio stops.

The FiX-LSA-4 fixes this problem by providing a lower load impedance so the FiX-82 will work with most factory amplifiers. If you have this problem, the FiX-LSA-4 is the solution!

FiX-LSA-4 General Features:

  • 4-channel Load Sensing Adaptor
  • Fixes a common problem with connecting the FiX-82 to a factory amplifier
  • Provides a lower impedance so the factory amplifier's load sensing circuit will allow the FiX-82 to work with it
  • Authorized Internet Dealer
  • 1-year Manufacturer's Warranty
