Maintained! The crossover has a 2-way specification of 800 Hz. A 2-way/3-way channel divider that allows you to change crossovers by replacing boards. Attenuation characteristics are possible by switching between -12 dB and -18 dB/oct (Daiki Goto)
Maintenance information: 2024.9.13 Maintained (1) Since RCH was -18 dB/OCT compared to LCH -12 dB/OCT, the low path blocking characteristics were reset to -12 dB/OCT as well as LR. 2) Each volume contact disassembly and cleaning procedure, bonnet mounting screw replacement 4) insertion loss 0 dB crossover frequency 800 Hz (-3 dB) Low, and 2-way operation with MID output was confirmed. Since it is a 2-way operation, there is no high output. 5) Other cutoff frequency slope switching SW and SUB WOOWER output switching SW disassembly cleaning, door catch magnet adhesion treatment. 6) Part of the heat-deformed audio electrolytic capacitor was replaced with an equivalent audio capacitor, and the energizing operation sound output test is good.)

Maintained! The crossover has a 500Hz 2-way specification. A 2-way/3-way channel divider that allows you to change crossovers by replacing boards. Attenuation characteristics are possible by switching between -12 dB and -18 dB/oct (Daiki Goto)
Maintenance information: 2024.9.13 Maintained (volume and crossover slope switching SW contact disassembly cleaning. 2) Due to buffer amplifier operation misalignment, replace the bias LED x 2. 3) Insertion loss LOW OUT 1.3 dB (Lch Rch) MID OUT 1.0 dB (Lch Rch) 4) The crossover frequency 500 Hz (-3 dB) was confirmed, and operation is good at a slope of 12 dB/OCT. The slope can be switched between 12 dB/oct and 18 dB/oct, and this unit is set to 12 dB/oct.)
