Bridged-Tee Attenuator The design advantage is that the input and output impedance of each gear is constant, so there will be no different sounds in different gears.
There is no circuit board. This is very clear. In order to avoid the influence of the inter-board capacitance of the PCB on the high frequency. After all, the passive design has no buffer. The pure scaffolding design consumes labor costs. Gick also completed this high-cost PM-1 for sound quality at any cost.
