Training Room Installation
In a typical training room application, microphone audio from the trainer is the primary source of audio. A wireless mic is normally used. Secondary audio is often provided through presentation segments sourced from a VCR or CD player. In larger training room settings, participants often use desktop microphones to enable all to hear questions and comments.

Figure 7.13 shows a scenario including a wireless lapel mic for the trainer; desktop mics for participants; ceiling speakers to carry voice (primary) audio and some secondary audio; and left and right speakers at the front of the room, which carry primary and secondary audio.

Microphone mixing and gating parameters can be set to favor the trainer’s mic to facilitate effective dialogue in the room. When a particular microphone gates on, nearby speakers can be set to reduced volume or muted to reduce feedback. Also, participant microphones can be set to gate off when secondary audio sources are in use.

The left and right speakers at the front of the room can be configured to provide stereo sound from a (stereo) secondary audio source, enhancing the training experience. All speakers can be optimized to produce full-fidelity audio by programming the PSR1212’s parametric equalizers and filters accordingly.

See the training room installation diagram (Figure 7.14).
