GOTO UNIT CF-1
3-way : ¥ 65,000 (around 1978)
4-way : ¥ 75,000 (around 1978)
Commentary
Channel divider designed for 4-way use using Goto unit.
The CF-1 was designed for 4-way use, but it could be used from 3-way to upgrade to 4-way.
NF type with sharp cut-off characteristics and good shoulder characteristics is adopted for the circuit type.
We use carefully selected parts.
The printed circuit board of the filter part is fixed type rather than plug-in type, which suppresses noise caused by contact resistance.
A constant voltage circuit is used for the power supply.
