The IN-9 Nixielyzer is an analog audio spectrum analyzer, based around the BA3830F analog analyzer chip. It offers the display of six selective audio bands:
63 Hz, 150 Hz, 330 Hz, 1 kHz, 3.3 kHz and 10 kHz.
As an extra feature, you can mix the signal of a build in microphone to the display, to use the IN-9 Nixielyzer as a stand-alone device when no audio source is connected).
The IN-9 Nixielyzer operates with six IN-9 Nixie Bargraph tubess and has two RCA stereo in- and outputs (for easy daisy chaining the device within an existing audio path) and also two 1/8" TRS jacks for simple connecting your MP3 player, mobile phone plus headphone for listening etc.
Both signals (RCA and 1/8" TRS are only internal mixed via an electronic zero ohms node and do not affect each other.
The IN-9 Nixielyzer uses no digital signal processor or FFT (Fast Fourier Transformation); so the display is stepless and fully in realtime.
Furthermore a modified dbx compandor ciruity was introduced to enhance the dislayed dynamic range.
The topology of the electronics corresponds to that of the proven EM800 Magilyzer circuity.
