Cartridge Loading for a phono pre amp
Hello,
I have recently acquired a phono pre amp recommended by Michael Fremer. It is “THE VINYL”, from QHW audio, Spain. It got a great review. I have a Benz Micro Glider rated at 1.1MV. I have no idea how to set the dip switches for MC Load impedance for this cartridge. The options I have are as follows: 47K, 1K, 560R, 470R, 100R, and 47R. I have a solid state amp and pre-amp, and also have a sub that I use, rarely.
Any advice would be most appreciated!!

Dear @fundsgon : So you agree that 47k is standard for LOMC since appeared as is in the MM/MI cartridges ? How on earth did you infer that I agree that 47k is standard for anything? Certainly not in my previous post. |
If JCarr really said this, then he isn't aware of how balanced operation works. A dynamic microphone is a balanced source because its floating. An Ampex 351 tape machine has a balanced output because the secondary winding of its output transformer is floating. My Neumann U67 microphones are a balanced source because their output transformers have a floating output. Atma-Sphere was the first company anywhere in the world to offer balanced line components for home stereo use. The equipment supports the balanced standard, known as AES48. In a balanced connection, ground is ignored- its not part of the audio signal. This is why in a phono connection with RCAs, you have that weird ground wire that no other single-ended source seems to need. This is because you have a balanced source that is being fed to a single-ended input, and you have to do something with the ground, which otherwise isn't connected to the audio signal, but is its shield nevertheless- that being the tonearm tube of course.
