The PH HV MM and PH HV MC are sophisticated modules designed specifically for installation in the HV series of integrated amplifiers and pre-amplifiers. These modules are relatively large due to their advanced discrete, channel-separate circuit components which enhance the overall performance of the system. The modules are housed in metal cases, providing additional shielding that results in excellent measured values.

The MM (Moving Magnet) module allows for the input sensitivity to be adjusted across eight different levels, offering flexibility depending on the specific requirements of the audio setup. This adjustment can be made with or without the engagement of a sub-sonic filter. Additionally, users have the option to select from sixteen different input capacitance values, ranging from 70 pF to 460 pF, providing further fine-tuning possibilities for optimal performance.

Similarly, the MC (Moving Coil) module offers the ability to adjust input sensitivity across eight different levels, again with the option to engage or bypass a sub-sonic filter. The input impedance can also be customized with sixteen settings, ranging from 55 Ohms to 1000 Ohms. This allows for precise matching to various phono cartridges, optimizing the overall sound quality and experience.

In summary, these modules provide high adaptability and precision for audiophiles looking to maximize the performance of their HV series amplifiers, through detailed settings for both input sensitivity and impedance/capacitance.
