thebes Posted December 18, 2006 Share Posted December 18, 2006 Thanks Mark and Max for the info. It was just a passing thought anyways since I'm coming into the "poor" part of the year on the financial side. Quote Link to comment Share on other sites More sharing options...
djk Posted December 19, 2006 Share Posted December 19, 2006 "The standard input impedance for MM is 47K." The termination impedance is 47K, the source impedance of the standard MM is 1K. The source impedance dominates the 1/f noise spectrum, and is the ultimate limit on the s/n ratio and the dyanamic range. "I think the lower source impedance of an MC cartridge is actually a result of its lower moving mass." In the sense that less wire = lower impedance = less mass. But that doesn't explain the Grado or the Stanton, both fixed coil designs. Most MM carts are actually induced magnet designs, very low moving mass. The actual magnets are fixed, so can be quite high mass. NEVER MEASURE THE RESISTANCE OF AN MC CARTIRIDGE !!! (you will ruin it). Quote Link to comment Share on other sites More sharing options...
