Aerpro AP3042A 2-channel Line Output Converter

by Aerpro

The Aerpro AP3042A is a super-compact 2-channel line output converter. Ideal for adding aftermarket amplifiers to factory head units in most 12V vehicles.

Many aftermarket amplifiers only have a low voltage audio input, this can be problematic when the factory head unit can not be changed or is preferred over aftermarket head units.

The AP3042A converts a high voltage signal from a factory head unit to a low voltage signal suitable for most aftermarket amplifiers. The built-in signal noise filter helps to reduce unwanted noise commonly picked up from factory head units.

The Step Down adjustable channel gain makes the AP3042A compatible with most aftermarket amplifiers and can also help adjust the signal voltage for individual channels.
