SINGLE MIX-MINUS NO TELEPHONE FEEDS
In some environments, it’s only important that the caller hear the in-studio host, and less urgent that the on-
air caller be able to hear automation, news reports, codecs etc. It’s possible that simply routing an amplified
version of the studio microphone signal to the “send” input will meet those needs.
Some studio telephone systems, like Comrex EarShot IFB, allow telephone callers to appear on one of two
outputs (and therefore on two, separate console faders). In this circumstance, you often have a choice of
delivering a single mix-minus with neither of the telephone audio sources present, or two distinct mix-minus
feeds. In the case of two feeds, it’s important to note that mix-minus A must include the caller audio B and
vice-versa. The following figure illustrates this concept. Many consoles with dual telephone channels are
designed to work this way, and should deliver the correct set of mixes automatically.
