An often-overlooked component in a premium sound system, the amplifier takes the audio signals from various sources within the vehicle and boosts them up to a more powerful level before sending them to the speakers. A quality amplifier can significantly improve the performance of the sound system by adding power and channel count.

As the market leader for automotive infotainment networking, we provide the products and the technological know-how needed for interfacing and connecting audio amplifiers with other audio components in the vehicle. In addition, our microcontroller and analog solutions have helped engineers complete innovative designs of audio amplifiers that reduce noise and distortion, enable refined signal processing and improve the overall performance of the vehicle’s sound system.


INICnet™ Technology

INICnet™ technology simplifies automotive infotainment networking with support for ethernet, audio, video and control over a single cable. INICnet technology can coexist with automotive Ethernet to seamlessly interface Internet Protocol (IP)-based data communications across vehicle domains, while providing efficient transport of audio and video data. INICnet technology does not require development and licensing of additional protocols or software stacks, reducing development costs and keeping development on schedule. INICnet technology supports a variety of system management methodologies via IP, or a dedicated control message channel. Data rates of 50 Mbps on UTP or 150 Mbps on coax or optical cabling are supported.
