Applications of the PH 15

  • Allows the connection for listening to the analog records with an input line of an amplifier, and is alsoconfigurable in two ways: one for the MC (moving coil), low impedance, with output voltage of 0.5 mV- 1 mV RMS, the other for all other MM (moving magnet, iron mobile, or high output moving coil) types,with output voltage 2.5 mV – 5 mV. Practically, it is compatible with any cartridges on the market.
