Home Theatres - The role of an audio / video specialist in setting it up

A Home Theatre For Your Dream Home
A place for you to watch movies at your leisure with the similar atmosphere of a cinema hall

What would you do first? Yes, all-in-a-box equipment is available in the market.

1. You can just buy one of those all-in-a-box home theatre equipment and connect according to the instructions provided there or as detailed by the sales man. Just think, you will be listening to this system either at their showroom or a place specially set up by them for getting the output from the system they sell.

2. You can approach an audio / video specialist to consult, design and install a home theatre in an acoustically treated room.

Well, if you are choosing the first option - could turn out to be a cheapest one or might be too good and costly to be accommodated in your space. Of course, you may feel the difference in quality in sound other than what you used to get out of your normal television or music system... But not a real theatre-like experience. Read on to find out why .......

There are many factors that can bring you a lively, theatre like atmosphere into your home theatre -

- The room you choose to set up your home theatre
- The type equipment you need for that room
- The floor of your room
- The ceiling of your room
- Wall condition of your room
- Lighting of your room
- Your seating & other furniture inside the room

It all started with just one speaker - MONO. All that we heard was from a single channel. Then it was a matter of excitement for all....

Then came STEREO, the first multi-channel system - two speakers.. two channels. Listeners were happy to listen to their favorite music, the frequency of which is changing from one speaker to the other. At those days, the efforts of many artists and recording engineers were applauded at lot.. But the revolution continued......
Then came a Multi Channel system with dramatic improvements...more realism - 3, 5, 7 channels... This is now a reality in cinemas, homes and cars...

The system was subject to some basic rules that have set a standard for multichannel film sound: well placed dialogue in the center of the screen, music and sound effects across the front and in the surround channel. Reverberation and other ambiance sounds are steered into the surround channel, as are sounds of aircraf, gunshots, ricochets and the like.

At times the audience can be:

- enveloped in sound as in a football game – multi directional sounds,
- transported to a giant reverberant cave or gymnasium – lots of reverberation,
- in the confines of a car engaged in a dramatic chase – multi directional sound, small room reverberation,
- treated to an intimately whispered conversation – no surround or ambiance.


To achieve this dynamic range of spatial experiences requires a flexible multichannel system, controlled-directivity loudspeakers, as well as a degree of control over the acoustics of the playback environment. When it is done well, it is remarkably entertaining.. The basic format of a front sound stage with enveloping “ambiance” is also the basis for most of our real life musical experiences, so audiences are immediately comfortable.It is important to note that the characteristics of the encoding matrix, the active decoding matrix, the spectral, directional and temporal properties of the loudspeakers and room all are integral parts of the functioning of these systems.

Starting from Dolby Surround...to a THX (minimum performance standards set for the electronics and loudspeakers) certified Dolby Prologic system - Home entertainment is much similar to a cinema hall... but only if your room is built to create the right ambiance and perfect calibration - The act of balancing the relative channel levels making individual channel adjustments until you get a smooth, seamless blend of front channel music and effects, dialog clarity, and surround effects when they are needed, and just the right amount of sub woofer bass.
