I, as I have been lurking around this tube audio section, have run across a reference to a "passive pre-amp"..
Now my interpretation of this oxymoron is a chassis/or box with 2 or more stereo jacks input jacks with a selector switch for the selection of line level inputs to be routed to a set of output jacks with a attenuator(not a volume control) for controlling the level in it`s simplest form..
An of course, it being a totally passive device with no active parts inside it has not the ability to provide any gain("pre-amplification") !!
So why is it called a "passive pre-amp"?
Instead of a audio line level selector box w/attenuator which is what it really is..
I guess that wouldn`t be sexy sounding enough, maybe ??
Just curious about the name ? And I do understand the reason for the device..
You may commence to pounce on me, if you wish !!
