What is a Line Output Converter and How Does it Work?
A Line Output Converter (LOC) is an electronic device that converts a speaker-level signal into a line-level signal, allowing you to connect your subwoofer to an amplifier or receiver that only has line-level inputs. The LOC works by taking the high-level signal from your amplifier or receiver and stepping it down to a lower level that is compatible with line-level inputs.
The LOC is typically installed between the amplifier or receiver and the subwoofer, and it can be adjusted to match the impedance and sensitivity of your subwoofer. This allows you to optimize the performance of your subwoofer and ensure that it is receiving the correct signal level. By using an LOC, you can connect your subwoofer to a wide range of amplifiers and receivers, even if they don’t have a dedicated subwoofer output.
Do I Need a Line Output Converter for My Subwoofer?
