The amplifier offers both tone control (bass & treble) and a switchable low-cut filter, allowing the audio quality to be fine-tuned to the room and speakers.
The PA-900S features a balanced XLR input, XLR line-out (feed-through) and screw terminals for speakers. It supports 100V, 70V and 4Ω systems, making it very versatile in commercial and public installations.
The ability to operate on a 24V emergency power supply in addition to mains power makes this amplifier suitable for critical installations where continuity is essential.
With a solid metal enclosure, a 2U rack height and included mounting brackets, installation is easy and professional.
