Recommended range of capacitance for M91ED

Date Updated: March 2, 2018 FAQ #503
Question:
sorry, my English is not so well...my terratec phono-preamp pc-interface asks me for the recommended rangeof the input-capacity of the pre-amplifier.I use a Shure M91ED.it is possible to choose between 100pf, 250pf and 425pf.the intention is to bring my vinyls to harddisk with wavelab from steinberg.
Answer:


With your pre-amplifier, use a capacitive load of 425pF for each input channel.
For the M91ED, the recommended minimum load is 400pF per channel and the maximum recommended load is 500pF per channel.
