Multi (4 or 8) channel amplifiers satisfying the most discerning installation / cinema requirements.
MC² I-Series
Networkable Amplifiers for Fixed Install, Cinema, & Residential applications

I-Series offers a versatile feature set including Lo-Z/Hi-Z direct-drive capability, that gives system designers scalable power at different impedances, and dip switch selection for various features. Bridging of channel pairs is also available, offering higher power delivery for larger load requirements.
I-Series incorporates Ultrafide Audios UltraSigma Hi-Fidelity modular output platform, scaled up for even higher power – This represents the VERY BEST in Pro Audio sound quality, whatever the load. This in-house modular class D topology is based on Delta-Sigma modulation, with supersonic switching techniques 20 times higher than the human hearing range – This offers new levels of sonic performance previously unheard in Pro Audio.
This first class sound quality is maintained over a wide range of load and temperature conditions, and sophisticated “side-chain” limiters prevent distortion and speaker damage, but are out-of-circuit until the onset of clipping. The control circuitry provides full protection against short circuits, DC and excessive temperature together with inrush current limiting.
Combining the above with GPO status / load monitoring/ GPI connectivity, optional Dante/AES67 card, and a truly universal PFC SMPSU, this makes I-Series amplifiers an obvious choice for many applications.
Green / Energy efficiency requirements are intrinsic to the design and further satisfied with rear selectable autostandby (2W).
