A huge selection of audio products. We have everything you need to design and install whole-house audio systems and home theater in-wall speaker systems. Plus we have the interconnects, bulk audio cable, connectors, adapters, converters, and selectors to hook it all up.
In this area, we present the rest of the "whole-house audio" story.
First, let's define whole-house audio; Whole-house audio is where you have multiple speaker pairs (stereo) in multiple
rooms or areas of your home. One or more rooms may have a full surround sound
setup. In a surround sound equipped room, although one set of speakers may be shared
with the whole-house audio system, they are otherwise separate systems. (We recommend the ABS1
Sound Activated Speaker Level Automatic A-B Switch Box to connect speakers to both audio systems.)
Each set of speakers is known as an audio
There are two basic ways to set up a whole-house audio system.
. With single-source, all zones hear the same thing (although some zones may be "off"
or have their volume at different levels). With multi-source, each zone may independently select an audio source.
The difference in cost and complexity is significant.
Until recently, true multi-source systems were
Recent products from Xantech and others have brought the price, and level of complexity, down significantly.
Because each installation is so different, it would be difficult to give you a step-by-step design guide.
If you wish to design your own system, the best way is to become familiar with the equipment
available, then you will begin to see the possibilities for your application.
The most important thing we have learned is to decide early on whether you want a multi- or
single- source system;
mix the two. For instance, if you are designing a multi-source system,
consider each set of speakers a
. Do not "extend" a zone by paralleling another set of speakers.
Although the amp may handle it, and impedance matching devices may correct the load, you'll never be able to control
the volume of each set of speakers the way you want.
The last point to get you started... Nearly all whole-house audio systems today have centralized amplifier(s),
with speaker level audio running to the remote zones. It is virtually impossible to distribute
"line level audio" throughout a home to remote amplifiers without unacceptable levels of hum creeping in.
