What is the difference between the R-122 and the R-122V?
The R-122V, slated for an early 2006 release, is the world’s first tube ribbon microphone. Use it anywhere you would use an R-122 and get that extra mojo that a tube provides.

A ground loop manifests itself as unwanted noise, buzz or hum (usually 60Hz or 120 Hz). The problem may be more apparent with lower output microphones such as dynamics or passive ribbons because of the high gain required for normal operation. Ground loops are brought on when the left and right transducer elements of a stereo microphone are plugged into two inputs of a stereo or multi-channel preamplifier. Stereo microphones usually have a multi-conductor cable that carries the two independent, balanced signals and then splits them to a pair of standard three-pin XLR outputs. This pair of three-pin conne
