What is Push to Talk: Push to Talk (or PTT) is an audience response system that allows users throughout BLM to respond directly to instructors, panelists, and others during a satellite broadcast. The process is simple. Want to ask the instructor a question? Press the button at the base of the microphone and begin talking - not unlike asking a question in a traditional classroom.

Configuring your Equipment: While the process of participating in a broadcast conversation is easy (press the button and talk), setting up the Push to Talk equipment and getting it properly hooked up to the satellite receiver, the VCR, and the TV receiver takes a little more knowledge.

Although everyone in BLM is using the same Push to Talk equipment (AT Products control boxes and microphones), not everyone in BLM is using the same kind of telephone line, the same kind of satellite receiver, the same kind of VCR for recording programs, or the same kind of TV receiver. This means BLM has to work with different kinds of equipment to achieve the goal of transmitting high quality audio during a satellite broadcast.
