Innosonix Multichannel Professional Audio Amplifiers Using EPC GaN Transistors for High-Density Class-D Design
Innosonix, partnering with EPC since 2020, was an early adopter of GaN transistors in professional Class-D audio amplifiers, overcoming industry reliability concerns.
Its multichannel amplifiers offer high-density 1U/2U racks with 16–32 channels, FPGA-based DSP, and Dante/AES67 or MADI networking for immersive audio installations.
GaN-based designs target 50–300 W per channel using ±60 V rails, leveraging EPC2059 150 V eGaN FETs for improved switching efficiency and fidelity.
