Power over Ethernet (PoE) audio amplifier units combine the functionality of audio amplifiers with PoE technology, allowing them to receive power and data over a single Ethernet cable. These units are commonly used in audio distribution and sound reinforcement systems, where both power and audio signals are delivered through the same network cable. These systems offer many benefits, including: simple installation, placement flexibility, central control, scalability, energy efficiency, and PoE network integration.
Overall, PoE audio amplifier units offer a practical and efficient solution for audio distribution and sound reinforcement systems, combining the benefits of PoE technology with high-quality audio amplification. Infineon meets all your needs with our system solutions for PoE audio amplifier units.
Professional audio equipment is all about maximizing output power and power density. Professional audio electronics used to be big, heavy and not very energy-efficient. But with the conception of Infineon's MERUS™ multilevel class D technology and gallium nitride CoolGaN™ e-mode HEMTs, it is now possible to conceive both amplifiers and power supplies units with great audio performance and high efficiency in a very compact space. For engineers developing amplifiers, Infineon offers both monolithic and chip-set solutions with versatile MOSFET combinations for the scaling of output power. This, combined with our power delivery over ethernet (POE) portfolio, allow you to source the whole system from one place.
High power, high reliability, and high flexibility MERUS™ discrete class D audio solutions combined with Infineon MOSFETs or GaN HEMTs for your distribution audio unit application.
The EVAL_AUDIO_MA2304PNS_B and EVAL_AUDIO_MA2304DNS_B are evaluation boards that feature the MERUS™ multilevel MA2304PNS and MA2304DNS stereo class D audio amplifiers. It features ultralow idle power consumption, highest efficiency in the market at typical listening levels, and reduced EMI, in comparison to traditional 2 and 3 level class D amplifiers. Additionally, MA2304DNS includes an integrated DSP for audio system tuning to facilitate development in a fast time to market environment.
When you use our MERUS™ class D audio amplifers, you can extend your battery life, reduce your EMI, lower your system cost, reduce the PCB area and footprint size, and introduce an inductorless ferrite bead operation without compromising audio performance, efficiency, and idle power consumption.
