AudioControl has introduced a groundbreaking audio amplifier platform leveraging GaN (Gallium Nitride) semiconductors from GaN Systems. AudioControl engineers have created a circuit that establishes a new bar for power and sound quality, now available in the CM Series 4-channel, 3-channel, and 2-channel 70V dual-mode amplifiers.

The AudioControl engineering team was tasked with elevating the performance standard for the 70V dual-mode audio amplifier category. 70V amplifiers are useful for driving many loudspeakers but have always suffered from performance limitations, often lacking clarity and reduced bass extension.

Now, in burgeoning resimercial markets such as bars, restaurants, retail outlets, and corporate offices/boardrooms as well as large residential/outdoor entertainment projects, the sound quality of 70V amplifiers had to be elevated to satisfy discerning clients.

GaN (Gallium Nitride) is a semiconductor material that was initially designed for the challenging demands of avionics, space, satellite, and 5G wireless applications. By using GaN Systems’ power semiconductors as the foundation for a new amplifier platform, AudioControl engineers were able to achieve high-output power, unparalleled efficiency, reduced distortion and ultra-low signal-to-noise resulting in outstanding sonic rendering from a highly efficient circuit that fits elegantly inside a sleek form factor.

AudioControl president Alex Camara says: “Our new Dual-Mode design effortlessly drives 70V speaker systems and standard 4/8Ω speakers simultaneously, achieving bass clarity and definition far beyond the capability of traditional 70V solutions. CM Series Dual-Mode amplifiers also incorporate AudioControl’s award-winning DSP engine, enabling integrators to fine-tune each zone for optimized sound quality.”

GaN Systems’ chief executive, Jim Witham, adds: “The AudioControl GaN amplifier design is a great example of combining system engineering innovation with the newest offerings in power semiconductors. Customers across the market spectrum are taking the lead in their industry by leveraging the many performance advantages of GaN.”
