HLCL34 4-Channel Converter

The Auto-Connect HLCL34 is a high-quality 4-channel high-to-low signal converter designed to integrate additional amplifiers into vehicles equipped with a factory audio system. It converts the existing speaker signals (high-level) into a Cinch/RCA signal (low-level) suitable for power amplifiers. This allows the vehicle’s original radio or infotainment system to remain in place.

With a power handling capacity of up to 80 watts RMS per channel, the HLCL34 is suitable not only for standard factory radios but also for systems that already include a more powerful OEM amplifier. The balanced signal inputs are designed to ensure signal transmission with as little interference as possible.

The output level can be adjusted directly on the converter, allowing the signal to be tailored to the downstream power amplifier. The included level remote control with a built-in voltmeter is particularly convenient. It allows you to easily adjust the signal level from the driver's seat while monitoring the vehicle's voltage at the same time.

An automatic power-on function detects the incoming audio signal and provides a remote output to power on connected amplifiers. This makes the HLCL34 particularly well-suited for modern vehicles where the factory radio does not have a traditional remote output.
