Yes, you don't want to send un-buffered (or unprotected) signals - 
especially right out of a filter - out for distribution. I have found 
that some pieces of equipment will only take the external reference 
over a certain small level range, so the distribution amplifier needs 
to have an assortment of levels, or some that are adjustable. Each 
instrument should have its own line from the amplifier unit, set to 
the right level, or for remote sending, a power splitter port from a 
common line.

unlikely to present 50 ohms to the filter. The more complex the filter,
generally the more sensitive it will be ....
