(Tiny Telephone) A miniature version of what is known as a phone jack, (phone plug) which is short for telephone jack, from the old days of telecommunications. We commonly refer to this type of jack as a 1/4 inch jack (our modern version actually is slightly different in size), which could come in TS and TRS forms. Switchcraft invented the TT jack (and corresponding connectors) many years ago to serve as a more compact alternative to the phone jack. Later another company, ADC, built essentially the same type of product, but referred to it as a Bantam connector. Nowadays the two names are interchangeable. TT/Bantam jacks and corresponding cables are commonly used in recording studio patch bays.
