CHAPTER 2: Introduction to the HAL System Windows Playback and Recording Programs that play back through your computers's speakers will play back through the RAD27 when you've set the Sound control panel as above. Windows doesn't include a sound recording program, but Audacity is a free ware basic audio editor and recorder and is available for download. You can simultaneously playback and record with two programs open. For instance, you can play from iTunes into the HAL system and record from the HAL system into Audacity. Using a RAD as a Portable Device Many audio systems have temporary device needs from time to time. For example, a teacher in a specific classroom in a school may only occasionally need to use a microphone or plug in a DVD player or a television. A meeting room in a hotel conference center may need a large number of microphones for a panel discussion, but only rarely. Instead of purchasing and installing the appropriate RADs to service all of these needs in all of these rooms, wouldn't it be much more cost-effective to have just a few of the needed RADs installed on, say, a rollable A/V cart that can be used when needed? The answer is, of course, YES! So how can you accomplish this RAD portability in a HAL System? You do so by installing one or more RADX devices (which are less expensive than other RADs) in the rooms needing certain audio functionality only occasionally. You can think of the RADX as an extension cord. You simply roll the cart (if that's what you're using) into the room and connect the RAD on the cart to the RADX in the wall. 41
