Absolute unique on the market !

The Magilyzer is an analog audio spectrum analyzer, based around the BA3830S analyzer chip. It offers 6 selective audio bands: 63 Hz, 150 Hz, 330 Hz, 1 kHz, 3.3 kHz and 10 kHz display.
The Magilyzer operates with 6 Magic Eye tubes and offers stereo line in- and output (for easy daisy chaining the device within an existing audio path) with level control incl. selection of the displayed channel (right, both, left), build in microphone with an audio mixer to add the microphone signal to the display or for using the Magilyzer as a "stand alone" device when no audio source is connected. In addition true electronic symmetrical 2 x 1/4" stereo TRS jack inputs are added. The RGB colour and brightness tube illumination can be adjusted according with sliders to your favourite colour.

With solder jumpers the Magilyzer can be configured for different Magic Eye tubes:
PM84, EM84, 6FG6, UM84, 12FG6, EM87, 6HU6, EM800, 6E2, 6E3-P

You'll get - except of the Magic Eye tubes and power supply, which are offered separate - a fully inclusive kit incl. all necessary electronical and mechanical parts (even the enclosure) to build and power-up the device within a few hours of your evening time.
The Magilyzer is an analogue design and uses no processor or FFT; so the display is fully in realtime.
