Multi-Zone Output Systems

Output Zones Defined

The term Output Zone refers to an area of a venue or building which has its own separate speaker system. Examples might be stage tower speakers, lobby PA, warehouse, store front, etc. Our audio products allow you to pipe sound to multiple zones simultaneously. Different sound or music sets could be playing in each zone with Sound Mill. You connect each speaker system to your computer via a multi-output soundcard or multiple sound cards. The approach you take to build your multi-zone system will depend on your budget, number of outputs needed, types of cable connections required and sound quality desired. Below are some sample alternatives to creating a multi-output system for use with Sound Mill or Matrix Mic Output Groups. If your sound card appears as a selectable device in the Windows Control Panel -- Sound and Audio Devices -- Audio Sound Playback panel, it should be visible to our programs. If the output ports are not showing up in Windows Sound and Audio Devices, there may be a DirectX driver available as a download on the manufacturer website.

High-End Multi-Zone Systems

The big theaters use expensive multi-output sound cards (ex. Delta 1010 - 10-In/10-Out PCI/Rack card - $750USD) to get the absolute best fidelity from their sound system. There are other 10-output cards that range from $200-500USD (ex. Delta 1010LT - 10-In/10-Out PCI - $250USD). Each port on these cards are generally recognized to Windows as Output 1 , Output 2 ... , etc.

Mid-Range Multi-Zone Systems

Not everyone has the deep pocket budget of a Disney production. You can get a 4 output USB or PCI soundcard with very good frequency response (ex. Audiophile 2496 - 4-In/4-Out Audio Card - $125USD). There are many options for under $100USD at many price points (ex. StarTech 7.1 USB Audio External Adapter with 2 outputs - $50USD).

Low Cost Multi-Zone Systems

If you need to build a system for the lowest cost possible and high sound quality is not necessary, you might try this approach. You can get USB External Sound Card Audio Adapters for under $10USD each (ex. 7.1 Channel USB External Sound Card Audio Adapter - $8USD, or External 5.1 USB 3D Audio Sound Card Adapter - $4USD ). Plug this Adapter into a USB port on the computer, and use the headphone jack (for output). Get a USB Hub ($15-30USD) to add more USB ports to your computer if needed. These audio adapters will appears as Audio card (1), Audio card (2), etc when detected by Windows. Tip: buy and test one adapter to see if sound quality is sufficient for your application -- the quality can vary widely. Some users have reported surprizingly decent quality sound from these considering the low cost.

The Hobbyist Guide to Multi-Zone Systems

If you are a hobbyist, you might want to experiment at home by putting speaker zones in the basement or garage. Or create an amusement attraction for your club or school. Here are some low cost, no cost suggestions. Get a few of the low cost external USB audio adapters mentioned in the Low Cost section above. For speaker systems, try a boombox with a line-in jack or a microphone jack and detachable speakers. Boomboxes have amplifiers to boost the audio signal coming from the computer USB audio adapters. Patch the output of the USB audio adapter to the line-in jack or a microphone jack of the boombox. Detachable speakers are desired because you will need to run speaker wire from the place where the computer is located, to each speaker zone location. Standard computer speakers are a potential option but you will need to get creative with wiring since the audio amplifier is typically located inside one of the speakers. It is clearly cheaper to run 50 feet of speaker wire than 50 feet of shielded stereo patch cable cable. You can often find used boomboxes and computer speakers at nonprofit stores such as Goodwill Stores. You can test to see if the soundcards are piping sound to the expected zones by plugging headphones into the USB audio adapters. Radio Shack has all the patch cables and connectors you might need to patch from the USB audio adapter to the speaker amplifier unit. And have some fun with it or what's the point?
