Nippon Audio Response Checker RC-1

[HighCtenor]

Hello EEEV members,

I am trying to find out about sourcing a Nippon Audio Response Checker RC-1 from somewhere...if possible in Europe. This an inexpensive frequency response checker which allows the use of a calibrated microphone. It is generally used for audio applications to test speaker frequency response. If someone knows about this or if there is a teardown somewhere let me know.

That looks like a cool device. I bet it is from the 80s. The same thing today can be done much better with software. Get yourself a XLR-USB adapter and a program like Visual Analyzer and get much better results.
