Our aim is to take the latest technology available to help our customers complete their measurements faster but without loss of precision. With the Nor-280 we have again met this objective.This power amplifier is the 4th generation of specially designed units for building acoustic measurements from Norsonic. It is less than half the size and weight, but twice as powerful as its predecessors; it replaces the Nor-260 as the preferred amplifier to drive the Norsonic range of full and hemi dodecahedron instrumentation loudspeakers.

Feauters:

• Specially designed for Building Acoustic measurements
• Lightweight and rugged construction
• Self contained noise generator
• 500 Wrms output power
• Emits 120 dB sound power level in the 50 - 5.000 Hz frequency range when used with Norsonic dodecahedron loudspeakers types Nor-275 or Nor-276
• Wireless remote control of noise generator (optional)
• Equalization network to optimise acoustic output from speaker
• Balanced signal input for low noise and limited cross talk problems

Applications:

• Sound insulation measurements
• Reverberation time measurements
• Absorption coefficient measurements
