Adaptive Class D Technology
ASL pioneered the use of Adaptive Class D Amplifiers throughout its Public Address and Voice Alarm range of products. High reliability and high efficiency are the key requirements for a Voice Alarm amplifier. High efficiency means smaller battery supplies and lower operating temperature. Lower operating temperature means increased reliability.
Traditional Class-D amplifiers offer high efficiency at full-power but also exhibit high quiescent power consumption. Battery backed Voice Alarm Systems demand the very lowest quiescent consumption. ASL ’s proprietary Adaptive Class-D system uniquely combines high efficiency with low quiescent power consumption, whether operating on mains or battery, guaranteeing the lowest power consumption and operating temperatures at all times.
The result is an industry-leading amplification technology with proven reliability over the last 10 years
