The MOSCONI HLA-DUAL is a compact, four-channel, high-low adapter designed to integrate amplifiers and digital signal processing (DSP) systems into modern original equipment manufacturer (OEM) audio systems.
Since many modern vehicles continuously monitor their speaker outputs and detect changes in the connected load, the HLA-DUAL is the ideal solution. Its integrated load simulation replicates the electrical impedance of a speaker, enabling seamless integration into modern vehicle architectures. This prevents malfunctions, such as speaker diagnostics errors, error messages, and signal shutdowns.
Designed for vehicles with high-power head units and BTL outputs, the HLA-DUAL allows for safe signal tapping at the speaker outputs of the original system. At the same time, the module generates a reliable remote signal by detecting the applied DC voltage. This allows amplifiers and digital signal processor (DSP) systems to be automatically turned on and off, even if no separate remote line is available.
Thanks to its compact design, the HLA-DUAL can be installed directly in the wiring harness or close to the head unit. The lack of a housing and connectors minimizes the required space, enabling discreet integration even in tight spaces.
