Nor280 Power Amplifier

The Nor280 Power Amplifier is a professional-grade 200 W RMS amplifier purpose-built for driving dodecahedron loudspeakers and other sound sources used in building acoustics and room acoustics measurements. With a flat frequency response spanning 20 Hz to 20 kHz, the Nor280 delivers the full-bandwidth power needed for accurate airborne sound insulation testing per ISO 16283-1, reverberation time measurements per ISO 3382, and sound power determinations per ISO 3741. The Nor280 integrates a built-in pink and white noise generator, eliminating the need for an external signal source during building acoustics measurements. Frequency shaping filters allow the operator to optimize the spectral output for specific test requirements, ensuring adequate signal-to-noise ratio across all frequency bands of interest. The infrared remote control enables convenient start/stop operation from outside the source room, which is essential for efficient field testing workflows. With multiple input options including XLR and RCA connections, the Nor280 accommodates both Norsonic signal generators and third-party audio sources. The robust construction withstands daily transport and use on active construction sites throughout the GCC, where building acoustics testing is increasingly mandated for residential, hospitality, and commercial developments. The Nor280 pairs optimally with the Nor283 dodecahedron loudspeaker to form a complete omnidirectional sound source system for standards-compliant testing.
