V. Operation of Earshot IFB
EarShot IFB only processes incoming calls. By default, callers are parked in a “waiting room”, and a prompt is
sent instructing the caller to enter a PIN. The PIN is pre-set by the administrator, and on verification the caller
is added to one of the four possible “feeds” based on the PIN. By default, callers can only hear the Feed and
not each other.
EarShot IFB has an optional IFB function. In this mode, one or two “Feed” inputs are repurposed as IFB inputs
and assigned to one of the other “Feed” inputs. When audio is active on the IFB input, the level of the “Feed”
audio is automatically reduced by a fixed amount, and the IFB audio is sent over the FEED at normal level.
This is designed to allow normal program or mix-minus audio to be sent to a caller, yet allow a producer or
director to interrupt the feed momentarily for directions.
As an option, callers can add their own audio to the feed audio to make a conference. This is done with a
special DTMF code sent from the caller. This is useful in a scenario where a producer or director is not in the
studio, but wishes to add his own audio to the feed via telephone.
