These questions pertain to using ceramic carts via the "Phono High" input on the 400, 500C and 800C. Yes, I realize that a ceramic cart could be plugged into an Aux line level input (but that would not be optimum from an EQ perspective).
Only the 400 manual lists an input sensitivity for "Phono High." It's not listed in the 500C or 800C manual. But like the 400, the 500C and 800C also have "Phono High" inputs.

- "Phono High" 14mV input sensitivity (Fisher 400 owners manual)
- Phono High is designed "for all ceramic cartridges with adaptors for magnetic inputs."
- 1. What does "adaptors for magnetic inputs" mean? Is that simply an RCA connector? Or does it mean something else?
- 2. If a ceramic cartridge with an output of 0.5V (500mV) is presented to the Phono High input, will that overload the Phono High input? The sensitivity is listed at 14mV (0.14V) -- but the headroom before distortion for signals above that input sensitivity threshold are not listed.
- 3. Additionally, how loud would a 500mV signal fed to Phono High be in relation to the relative loudness of FM tuner?
