Pascal has announced the launch of two new extension modules for its highly popular S-PRO2 power amplifier module, with immediate availability: the 2 x 500 Watt S-A2 and 1x 500 Watt S-A1. The new boards enable a range of new, cost-effective power configurations for self-powered and multi-channel amplifier applications.

The S-A2 and S-A1 extension modules function as additional identical amplifier output channels for the S-PRO2, powered by the S-PRO2 power supply. Pascal UMAC class-D technology ensures that any S-PRO2 + S-A1/2 configuration delivers true audiophile performance, with high signal-to-noise, ultra-low distortion and exemplary frequency response specifications. While Pascal UREC power supply technology and PFC functionality provide universal mains and regulation for worldwide AC mains compatibility and consistent power performance.

With the new extension modules, the S-PRO series now offers a wide range of scalable power rating and output channel configurations for OEM self-powered and other integrated amplification applications – specifically sound reinforcement and portable PA speaker cabinets, high-end studio monitor speakers, installation distributed 19″ rack amplifiers and home theatre 19″ rack amplification.

Typical applications for the new extension boards are for PA speaker cabinets with 2 or 3-way power configurations, deploying the S-PRO2 in bridged configuration with the addition of an S-A1 or S-A2 module providing either 500 or 1000 Watts to the LF section.

In high-end self-powered studio monitors, the addition of an S-A1 or S-A2 module to a bridged S-PRO2 configuration will provide either 3 x or 4 x 500 Watts per channel power systems. In distributed 19″ rack and home entertainment rack systems, a single S-PRO2 + S-A2 configuration will provide 4 channel (250 – 500 watt) outputs (at 8Ω – 4Ω load), or 8-channel outputs with a dual S-PRO2 + S-A2 configuration. For home and private cinema surround sound applications, dual S-PRO2 + S-A2 + S-A1 module configurations will provide 7-channel (250 – 500 watt) outputs.

Sales director Peter Frentz stated: “We were the first to introduce the world smallest 1000W amplifier module with the S-PRO2, which is today an acknowledged blockbuster in the pro-audio market. With the new S-A2 and S-A1 extension boards, we bring a new level of competitive advantage to our customers, in performance, price and time to market.”
