Build a Simple Multi-Room Music System Using a Receiver
The simplest multi-room music system uses the Speaker B switch built into a stereo or home theater receiver. The Speaker B output is capable of powering an additional pair of speakers, even if they’re located in another room. All you need to do is run lengths of speaker wire to connect it all together. People who might want to add more sets of speakers can do so with a separate speaker selector switch. And if you want easy access to adjustments, control plates can be added in conjunction with the switches.
Multi-Room & Multi-Source Systems Using a Receiver
Many home theater receivers have built-in multi-zone and multi-source features, which means each room or zone can listen to a different audio source (such as a CD, DVD, streaming device, or turntable) at the same time. Some receivers have powered multi-room outputs for stereo music (and sometimes video) in as many as three zones, and some models have line-level (non-powered) outputs, which require a separate stereo amp in each zone.
Music Over a Wired Home Network
If you own a home with computer network wiring already installed, you have an advantage. Running wires through existing walls is one of the most difficult and expensive parts of installing whole-house music systems. Network wiring with CAT-5e or CAT-6 cable used to interconnect a computer network can distribute line-level analog and digital audio to remote zones via multi-zone audio systems available from several manufacturers.
Music Over a Wireless Home Network
If you don’t have a pre-wired home network, and if retrofit wiring is too much to consider, there is another solution: wireless. As wireless technology has improved, so have the options for wireless audio distribution. It’s a great way to enjoy your personal music library or other audio sources throughout your home. The most common wireless technology is Wi-Fi. No doubt you have heard the term used for wireless networking of computers. That same technology has been finding its way into multi-room audio systems.
Simple and Affordable Wireless Audio Solutions
The simplest and most affordable way to send audio content wirelessly from one room to another is with a digital media or wireless adapter, available from a number of manufacturers. These adapters send audio signals wirelessly between two or more components, such as between a PC and a stereo receiver (or a subwoofer), or a receiver and a tabletop system. You can enjoy wireless music almost anywhere, as long as you have a steady connection. You could also use Bluetooth to connect speakers (or even headphones) to audio sources, although it requires a few more steps to set up. But the good news is that additional adapters are relatively inexpensive and can quickly expand a system to include more rooms.
Music Over Existing Home Wiring: Power Line Carrier Technology
Power Line Carrier (PLC) technology, also known by the name HomePlug, sends stereo music and control signals throughout your home via your home’s existing electrical wiring. PLC products can retrofit a whole-house music system without needing new wiring. Full systems and components are available or in development at a range of prices and features.
Whole-House Music Distribution Systems
Whole-house music systems have a central component that sends music from selected sources (such as a CD, turntable, or radio) to each zone. It can send either line-level signals to amplifiers in each room or have built-in amplifiers and tuners. All of these systems allow you to listen to any source in any zone and can be expanded from four to eight or more zones.
In-Wall & In-Ceiling Speakers for Whole-House Systems
In-wall speakers are a great idea for whole-house music systems. They offer good to excellent sound quality, don’t take up any floor or shelf space like standard speakers, and can be painted to blend in with room decor and virtually disappear. However, installing in-wall speakers involves more work. Walls must be carefully cut, and wires have to run through the walls to connect to components. Depending on the difficulty of the job, the number of speakers, and your skills, installing in-wall speakers can be a do-it-yourself project or may require the services of a custom installer or electrician.
