    Hi Guys,

    Could anybody tell me what the advantages or disadvantages are in using a simple balanced 'tee' attenuator over an unbalanced one?

    Obviously the difference is that a balanced design presents an equal resistance on both input-output lines, but why is this desirable in, for example, an audio application, or indeed any other application?

    Thanks a lot.

    Seems I was being silly. Is it that a balanced attenuator is for use with balanced signals? ie. 2 inputs 180 degrees apart?

    Having Balanced Audio is desirable, but an attenuator is an attenuator, you use the correct type for the transmission line in use.
