Specifications
The P-75 is a stand-alone phono to line level amplifier. It can operate with the following
cartridge types:
Cartridge Type Input Sensitivity Gain Loading
Low Output Moving Coil 0.2mV (200 µV) or 60 & 63dB 30, 100, 470 ohms
Standard phono stage 0.15mV (150 µV)
Low Output MC Zero ohms
Phono Enhancer*
High Output Moving Coil 2mV 40dB 47k (47,000) ohms
Moving Magnet
Moving Iron
*Input sensitivity and gain is determined mainly by the cartridge internal resistance.
Three resistance/gain adjustments available.
Always turn off power to the audio system (including power to the P-75) when altering
jumpers or settings inside the P-75.
NOTE: Under no circumstances should a signal generator be used with the phono enhancer
circuit, as any excessive current from the generator may damage the P-75.
All the above adjustments are easily made by the user. No soldering or extra components
are required.
