MUSWAY HL2 2 Channel High/Low Converter With Error Protection System

Description

In modern vehicles, it is increasingly no longer possible to replace the factory car radio. However, in order to be able to connect components such as external amplifiers or active subwoofer systems, a low-level cinch output and a switch-on signal for the external devices are required.

A practical solution is a high-low adapter such as the HL2 from Musway, which is connected to the speaker outputs of the original control unit/car radio and then generates a clean low-level signal for other components.

Modern vehicles often have the so-called “load detection circuit”. If the impedance is changed on the original control unit/car radio, error messages often appear in the device. The intelligent EPS circuit of the HL2 counteracts this and “tricks” the device into thinking: “Everything is OK”. With an input voltage of up to 18 V/RMS, the HL2 can even be operated on strong speaker outputs. Of course, the HL2 is also start-stop capable.

The developers are particularly proud of the brilliant sound quality. With a transmission range of 5 Hz to over 80,000 Hz, the HL2 effortlessly transmits every audible frequency range and even delivers the output signal at an incredible 5 V. The automatic switch-on function works via signal input or via DC offset and then generates a switch-on signal for other external devices.

In addition to the very good sound, the design was also important to the developers. It is noticeable that the housing is made of aluminum. The housing cover is flush with an acrylic plate. When switched on, the MUSWAY logo is even illuminated.
