Power Amplifier Nor282

Enquiry Item

NEW battery operated amplifier!

The power amplifier ensures that you get the maximum sound pressure level out of the Norsonic range of speakers.

With the Nor282 we have removed the need for signal and mains cable and added a graphical equalizer. Thanks to the large colour display and the graphical equalizer it is easy to adapt the speaker’s frequency response to the room response to fulfill the requirements for difference between adjacent 1/3 octave bands as per ISO 10140-5 and ISO 16283-1.
