Source-Talkback is a plug-in pair for Pro Tools designed to enable talkback
functionality without requiring external hardware, using a single
keyboard stroke for toggle and latch. Simply place the Talkback plug-ins
on your aux track before your talkback input, and on your Master fader.
Hold down the '\' key for toggle, or shift+\ for latch. Talkback allows
for an engineer to talk to talent either over Source-Connect and/or in a
local booth while not getting feedback through the monitoring speakers.
Source-Talkback is also compatible with any remote connection method,
for example ISDN, regardless of where you get your signal from.
Source-Talkback features system-wide recognition, so you don't need to
have either of the plug-in windows open, or even to have Pro Tools be
the front-most application.
Source-Talkback acts like a dimmer switch - you press 'TALKBACK' and when you speak into your microphone the sound coming in from Source-Connect is dimmed. This means, when you are talking the studio you are connected to will not get feedback from you speakers. When you turn TALKBACK off, they won't be able to hear you or themselves. Effectively, Source-Talkback emulates the hardware Talkback switches found on consoles.
When working with talent at your studio or remotely via Source-Connect (or any other method of connecting to another studio) whether it is across the hallway or across the world - you probably want to listen to the connection over your speakers rather than over headphones. This means that your connected partners will hear themselves back in your microphone, making it difficult for them to speak. If you are in your studio, you may have hardware at your disposal that provides talkback functionality: some analog mixers or control surfaces such as the D-Control come with built-in talkback functions. However if you are on the road or using a smaller setup like a Pro Tools LE or M-Powered, you may not have built-in talkback. The Source-Talkback plug-ins solves this problem for you, more efficiently and more conveniently than spending more money on an additional hardware piece to lug around just for a single, simple feature.
