We used to call the 15 kHz lines provided by the telephone company
'Balanced Transmission Lines' back in the day. I used them on live gigs
that were simulcast. At Sunset Sound (Late 1970's), we ordered a pair to
go from Capitol Records to Sunset Sound so we could use the live echo
chambers at Capitol. It didn't work well in spite of all of our efforts.
