Maintained. We have all UNIT modules 0 to 4! This channel divider is very easy to use. It is possible to switch from 2 way to 4 way with a single switch, including switching the crossover frequency. The exterior has small scratches and dullness appropriate for the model year (Oikawa Tetsuji)
Maintenance information: 2024.2.4 Maintained (The normalized wiring of the 2 UNIT0 modules in the modified part has been corrected. We have confirmed the normal operation of LPF/HPF with the module alone. It is sealed with a module screw lock. The DC offsets for all channel amplifiers have been readjusted. The cutoff frequency characteristics and phase characteristics of all module units were measured, and all module frequency errors were confirmed with phase differences. (We have confirmed that the phase error between each module is within ± 5 degrees at all frequencies)
Accessories: modules 0 to 4
Main specifications: 2/3/4 way crossover variable frequency Bessel function filter W480 x H80 x D 400 mm 8.5 kg
