I-Series Amplifiers Networkable Amplifiers for Installation

Multi channel scalable power amplifiers with Lo-Z/Hi-Z direct-drive capability, satisfying the most discerning installation / cinema amplifier requirements. A versatile feature set gives the designer scalable power at different impedances with dip switch selection of Lo Z / Hi Z modes, and bridging of channel pairs for high power delivery. I-Series represents the VERY BEST in Pro Audio sound quality, whatever the load with the implementation of our sonically superior Sigma design platform popularised by our ULTRAFIDE brand. Our in-house modular class D topology is based on Sigma-Delta modulation, with supersonic switching techniques 20 times higher than the human hearing range – This offers new levels of sonic performance previously unheard of in Pro Audio. 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. The 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. Green / Energy efficiency requirements are intrinsic to the design and further satisfied with rear selectable autostandby (2W). Available with or without dante cards. Direct drive (“Transformerless”) Hi-Z operation Flexible GPO reporting of Load, Standby status and OK status. Main GPI control of Standby / On state
