4CH Active Line Output Converters with Bass Restoration + Ba


The AX-BXLOC2-PRO from Axxess prevents factory audio systems from regulating lower frequencies and reducing the output of bass frequencies as the volume increases. A Bass-X restoration circuit in the LOC allows users to enjoy their music as it was recorded while maintaining the use of factory volume and steering wheel controls. This compact line output converter with active input circuitry accepts speaker-level signals of up to 400 watts per channel from factory-installed source units or amplifiers. They convert them to high-quality preamp signals that can be directed to aftermarket amplifiers. Unfortunately, some factory radios or amplifiers stop passing audio when OE speakers are disconnected – the AX-BXLOC2-PRO fixes this problem with built-in load resistors. A bass remote control with a digital voltmeter is also included to help prevent equipment damage.
