10.6 Dealing With Delay
Mix-Minus
All perceptual coders have too much delay for talent on remote to hear themselves via a round ‐
trip loop without an "echo" that can he annoying and disorienting. Therefore, a special mix ‐
minus (sometimes called a "clear feed" or "mix ‐ minus one") arrangement is required – exactly
the same as has been used with satellite linked remotes for years. The European term “mix
minus one” is clearer in the most typical situation.
The principle is this: The remote talent does not hear himself via the studio cue return. Rather,
his microphone is mixed locally with a studio feed that has everything but the remote audio –
thus the “mix ‐ minus” designation. The announcer gets in his headphones a non ‐ delayed version
of himself and a slightly delayed version of all of the studio pieces.
Most modern digital console can be configured to generate mix ‐ minuses without user
intervention. If you are using an older console that does not have this ability, or a non ‐ broadcast
console, here are some methods you can use.
Examples of mix-minus set-ups:
Example 1: Using a broadcast console (mixing desk)
The simplest form of mix ‐ minus involves using a dedicated bus to feed the
Xstream. In this case, we show Audition feeding the Zephyr Xstream. Note
that Fader 5 (a stereo input) is NOT assigned to Audition.
