Home Theater
With a dedicated Home Theater, the “Theater” experience can be brought to the comforts of you're own home. These rooms are dedicated strictly for the theater experience. Reclining theater seating on risers are strategically located in the prime listening area of the room. Surround sound is decoded via a fully capable, surround DSP upgradeable surround processor. Amplification is usually provided by THX Ultra certified multichannel amplifier(s). Speakers and subwoofer(s) are hidden behind fabric wrapped acoustic screen-wall panels. Video is almost always provided by a projector and large 92" to 135" film screens. Lighting control and motorized window treatments can be crucial for optimal viewing. The room can be made very dark, for optimizing the contrast ratio, even on a sunny day.
If the room is not optimal, this causes listeners to turn up the audio in order to compensate. Amplifiers are driven much harder, speakers are pushed to distortion levels.
In order to fix this problem, you'll require the surround processor to make extensive adjustments, decreasing some levels and increasing others. Then that information is sent to the amplifier(s). The amplifier(s) needs to boost only certain frequencies.
Custom Acoustical Treatment can bring your theater sound system to its peak performance. This calibration of room material(s) is sometimes forgotten but plays a major part of a custom home theater. Room acoustics consist of three main types of materials; absorptive, reflective and diffusive. Theater design consists of calculation the room dimensions. Then checking this data against preferable algorithms that deter standing waves, dead spots, etc. These calculations will help flatten the audio levels so you have a better reference point.
If a room has lots of absorption material like carpet, seating, thick curtains, the can sound acoustically “dead”.
Reflection occurs from large, flat, dense materials. The sound waves bounce off of the surfaces. Too much reflection causes an echo effect.
Diffusion material scatters the sound into random directions. Behind the seating position, it is desirable to have the room a bit “live” so the sound can bounce around and create an enveloping surround field. Too much of this material can cause an unrealistic effect that distracts the listener from the intended sounds.
Therefore each part of the room is studied. The right balance of all three of these acoustic materials creates an acoustically flattened theater, providing a sound reference point.
Room calibration... this can sometimes be a gray area when it comes to the preferred sound setup. An example would be creating a boomy effect by overdriving the subwoofers. It may be impressive for the one big explosion of the film, but you may struggle hearing the dialog. So our preferred method is to setup the system to reproduce all audio as intended. One of the many steps you can do to test your system is by playing different cd tracks, then playing different DVD movie scenes. If you don't have to adjust the treble, bass, or speaker levels, you've done a good job.
Media Room
These are multi-functional rooms for entertaining guests, movies, video gaming systems, Internet access. The seating may include theater seating, couches, love seats, and reclining chairs. An integrated surround receiver and smaller speakers are used to save space and cost. Multiple televisions are a good way to show several TV games at one time. Video is can be provided by a 50" to 80" rear projection television or a 50" to 61"Plasma Screen. Acoustic treatment is minimal.
