PH HV MM 
PH HV MC

These modules were specially developed for installation in our HV series of integrated amplifiers and pre-amplifiers. For this reason they are relatively large and feature very sophisticated circuit components, as they are of discrete, channel-separate construction. The metal case provides additional shielding and excellent measured values.
The input sensitivity of the MM module can be set to any of eight levels, in each case with or without sub-sonic filter. Sixteen input capacitance values are available.
