<div>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.</div><div><br /></div><div>Cheers!</div><div>CB</div>

Because the telephone company was how radio stations sent program material from remote broadcasts to the studio, and from the studio to the transmitter. Many of the 111Cs people have collected were abandoned on telephone backboards in radio stations.<br class="" /><div><br class="" /><blockquote type="cite" class=""><div class="">On Feb 1, 2022, at 6:51 AM, Bob Katz via ProAudio <<a href="mailto:proaudio@bach.pgm.com" class="">proaudio@bach.pgm.com</a>> wrote:</div><br class="Apple-interchange-newline" /><div class="">
