3-channel bulb-tube type divider kit with NF type filter circuit.

By freely combining among 96 capacitors, the crossover frequency can be freely selected for each channel.

Plug-in board type is adopted so that crossover frequency can be easily changed.
It is also possible to shift up to ± 5/8oct in a nearly continuous manner (1/8oc. per step) based on the selected crossover frequency.

The cutoff characteristics of each channel can be switched between 6dB/oct. and 12dB/oct.

Equipped with left and right independent level control.
