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.
The input sensitivity of the MC module can also be set to any of eight levels, in each case with or without sub-sonic filter. Sixteen input impedance levels are available.

MM
Input sensitivity 1,0 up to >10,0 mV
Input capacitance 70 up to 460 pF
MC
Input sensitivity 100 up to >1200 µV
Input impedance 55 up to 1000 Ohm
