The Fono disk stage is designed to amplify the signal from a moving coil cartridge to a level which can feed into a 200mV line level input on a standard hi-fi amplifier.
Specifications
Output impedance = 200Ω
Recommended minimum output load resistance = 5K
Frequency response (50KΩ output load) = 13Hz (-3dB) to 100KHz (-0.3dB)
