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
The disposal price has been reduced! Member prices are not applicable. 2022 9/13 sales price 198,000 yen*There are no UNIT0 and UNIT1. All deteriorated parts have been replaced, and every detail has been maintained! It's a very easy to use channel divider. The ease of use that can be freely changed from 2-way to 4-way, including crossover frequency switching, shines (Sasaki Shota)
Maintenance information: 2022.9.13 Maintained (Refresh maintenance has been performed. Electrolytic capacitors, tantalum capacitors, rectifier diodes, semi-fixed resistors, relays, pilot lamp replacement, SW/VOL are completely disassembled and contacts repolished, so conductive grease is applied to make it difficult to oxidize or sulfide over time It's being assembled. circuit adjustment. Check input/output waveforms)
