I know  that various forms of coax have different delay factors... what's the 
 
delay factor of twisted pair at audio freq's? Still, to attain 4 seconds,  
that's amazing! It would take 744,000 miles in free space to get that much  
delay. 
I don't imagine the distribution amps added much, did  they?

Before the days of Satellite.  The was alot of delay in the telephone  lines 
and the number of amplifiers between the major network  centers.    I used to 
work football games that fed to Detriot the  went to New York where the 
network was fed.  All via network 5 kHz.  lines.  Our talent would only use their 
headphones off the return monitor  feed when they had to talk back and forth on 
interviews or to do a remote  interview.   The delay was enough that it could 
be annoying to  talent.  I many time monitored for commercial cues etc.  But I 
would  assume that it was a second or two.
