Depending on the combination of modules used within a power amplifier, it is possible to drive any share of the total power capability reservoir to any output stage. This offers installers and integrators complete freedom to drive exactly the required amount of power precisely where it is needed. This has a major operational advantage in addressing asymmetrical power requirements within a zoned installation, with the benefit of handling a wide range of different or changing power requirements from the same power amplifier. It also avoids paying for excess power in such applications, which otherwise require use of multiple, fixed rated power amplifiers.
All modules in the range feature Pascal’s plug-and-play 26-pin interconnect, making them inter-connectable to a single front-end I/O / DSP board design. A single front-end module can thus be used in multiple power amplifier design configurations, reducing the required engineering work across multiple product design projects.
According to Pascal, the company's proprietary UMAC Class-D technology provides the highest power density / lowest form factor ratio of any ultra-compact amplifier module design. "Among the highest power rated modules in the world, these modules offer unmatched levels of sonic performance, quality, efficiency and reliability from a dedicated pro audio design. Premium sound quality, in a pro audio optimized amplifier, includes best–in-class signal-to-noise, distortion and dynamic range specifications. Exceptionally high voltage rails – and the ability to drive low impedance modes provide massive power headroom, for exceptionally high peak SPL ratings," they state.
All modules are equipped with comprehensive protection features and are designed on an ‘audio-at-all-times’ principle, rendering them fully self-protecting. Pascal amplifier modules improve system efficiency, minimizing requirements for heat sinks and cooling, and contributing to their unrivaled long-term reliability.
Energy Star Compliant auxiliary power outputs, readouts and control signals are available to feed integrated DSP or analogue I/O boards. Advanced real-time readouts of protect/mute, temperature and clip signals are accessible for DSP and network control implementations, and I/O stages. At the same time, UREC PFC power supply technology enables universal AC mains operation, allowing the modules to automatically adapt to any mains voltage between 100 V and 240 V, to deliver regulated power anywhere in the world.
With the announcement of the new modules for professional audio applications, Pascal also confirmed that Michael Munch recently joined Pascal as Product Manager, a position he held for several years at LabGruppen. "Pascal is known as the leading provider of high power, highly reliable amplifier modules for self powered, pro audio speakers," he says, "It is a natural step for the company to help clients meet market requirements for more compact, more versatile power amplifiers with a series of application dedicated amplifier modules. These modules offer the same standards of performance and reliability, with world leading power density and dynamic power ratings."
