[ProAudio] Western Electric 111C transformers

[CBAUDIO]

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.

Cheers!
