Commentary
3-way electronic crossover divider.
The crossover frequency can be selected from a total of eight stages, four between low and middle range and four between middle and high range, by switching two rotary switches.
As a result, it can be used as both a 2-way system that divides the low and middle frequencies and a 3-way system that drives the low, middle and high frequencies with their respective power amplifiers.
The cutoff characteristics can be switched between 2 levels of 6dB/oct. and 12dB/oct. depending on the characteristics and preference of the speaker. Both high and low frequencies can be switched separately.
Each of the left and right mid-range and high-range outputs has its own level control.
Equipped with a direct terminal, it is possible to compare and listen to the electronic crossover method and the standard method (network).
