How to use it

Using the Telephone Patch can be tricky, but here is some helpful info.

FEEDBACK
- Why does it happen?
  - Because the Telephone Patch does not perfectly cancel what we feed the caller from what we get from the caller.
  - A participant speaks into an open mic, it is fed to the phone line, but some comes back into the speaker.
- What can we do to minimize it?
  - Minimize the number of microphones which feed the Patch
    - Try to keep it to the moderator/host only
    - This minimizes the number of microphones which can contribute to feedback.
  - Monitor speaker optimization
    - Position the speaker so the participants can hear, but not be picked up in their mics.
    - Keep the level low enough that it can be heard, but not echo around the studio.

OPERATION
- Always test the Telephone Patch before the program starts!
- "Jockey" the mixer so that:
  - When the caller is talking most (or all) the studio mics are down (or off).
  - When the studio participants are talking, the phone is down (or off)
