The amplifier features a balanced 670 mV XLR/6.3 mm combo input, making it easy to integrate with mixers, preamplifiers and audio sources within professional broadcast and sound systems. Via the XLR feed-through (link-out), the signal can easily be relayed to additional power amplifiers.
The PA-912S provides comprehensive overheat, overload and short-circuit protection and shows status via LED indicators: clip, protection, overtemperature, output level and 70V/100V selection.
With its compact 1U height, only 3.5 kg weight and screw contact connections for speakers, the PA-912S is a flexible and reliable choice for a variety of 100V projects such as hospitality, retail, conference rooms and complete public address systems.
