Locomotor adaptations The most noticeable adaptation of cetaceans to life in the water is their locomotive system. Because cetaceans descended from mammals that moved their limbs in a vertical plane rather than in a horizontal plane, they use vertical strokes when they swim, instead of horizontal strokes like a crocodile or fish.
There are always personal preferences, decor objectives, etc. Everyone is entitled to operate their sound system as they see fit. Whatever you do, enjoy experimenting.
You could discover something great! ONE loose and crackling wire, in an otherwise pristine system, will cause the owner of the system to remark that the whole thing sounds like junk, or worse. I would suggest that the utmost care and attention be paid to what you might initially think is the smallest detail - such as contact cleaning and enhancing chemicals The point is people are different.
You may like something completely different than what any artist, record producer, or engineer ever intended! There is, therefore a very wide range of what you might personally consider "loud enough" or "enough bass" or "too loud", etc.
Fortunately the engineers at THX studied this very carefully and came up with a technical set of parameters designed to minimize the confusion. The whole concept of surround sound is a complex psychoacoustic phenomena which if set up well is convincing, and if set up poorly is annoying at best, and becomes frightening to some, because people are not used to, nor prepared for, sounds coming from behind them without turning around to see what the sound is; and in the case of a movie this becomes a momentary distraction instead of an emotional concentration toward the screen.
Many people put surrounds too high or behind them -and then turn them up too loud and the result is not pleasant. My suggestion is to START with everything set at a calibrated, neutral position and that includes the correct geometric placement of the speakers as I will explain and then work outward from there, continually fine tuning your system mechanically and electrically until you feel it sounds right to you.
This is not a trivial issue. Expect to spend a few weeks at this. There are suggested setups for those who might like classical music and like the feeling of being, for example, in the 5th or 15th row center. This also brings up a whole series of questions such as, "How was the piece mixed?
From whose vantage point? From the 5th row center concert seat? The soundtracks for the Theatrical release of the same film is usually different: Some people concentrate only on the picture and the visual phenomena, and then stick some speakers up wherever they can.
That result is often disappointing. If, after the system is completely set up, you find yourself "leaning in" to the sound, subconsciously trying to get "closer" or "more immersed" in it then I would suggest repositioning your seating so you are somewhat closer to the picture, then reorganize the speakers.
Sometimes a good way to determine speaker placement is to set up ladders with boards between them and keep moving things around until you are convinced things are the way you like them.
The closer together and lower the L and R are to a certain extent the more "intimate" the effect. But movie engineers and mixers have had a REAL center channel to work with, and so operationally we now have the following sub categories: Music mixed in stereo Music mixed in surround 5 channels Film mixed in surround for the theatrical release.
Film mixed in surround for the home DVD release. Different film mixers and rock n roll mixers have rather varying operational philosophies about all of this.
Do not expect to play a movie DVD and then switch to a rock n roll CD and then switch to a classical CD and not expect to have to adjust things. This brings up a serious point: Just because you think your system is calibrated, there is such a wide range of program material differences that you essentially MUST adjust each and every disc -- perhaps each and every song, if you want to lean towards being an audio perfectionist.
For the movie, the real C channel is essentially for dialog, and therefore should be placed as close to the spot on the screen where the actors mouths are! Unfortunately this means right in front of the picture, which of course we typically cannot do The L and R can go somewhere near the centerline of the picture, or a little higher.
The L, C and R tweeters do NOT necessarily have to be lined up as long as they are not too far many feet away from being in a line. In other words, if the C is below the picture, the LR might be on a line 2 or 3 feet above where the C is.
When figuring out these angles and setups, it is a good idea to make the subtended angle of the L and R speakers 60 to 75 degrees, with 60 degrees being the preferred number. More about this will be shown in the diagrams below.Cetacean: Cetacean, any member of an entirely aquatic group of mammals commonly known as whales, dolphins, and porpoises.
Cetaceans are entirely carnivorous. Their ancestors moved their limbs in a vertical plane, and thus cetaceans use vertical strokes when they swim, instead of horizontal strokes like a crocodile or fish. Feb 05, · The basics in how to set up a basic PA System and on how to run it.
Shows how to connect a micophone and iphone/computer cable to a mixer. At first hearing a rubber mat will allow more detail, but you may discover after a while that these are make believe refinements. Peaks in the frequency curve should be avoided at all times.
A relatively hard mat is the best option: acrylic (Goldmund type), hard rubber (the Technics SPmk2 type). Dec 27, · How to Set Up a Sound Board A soundboard (also known as a 'Mixing Board', 'Mix Console' or 'Sound Desk') is a complex and sometimes intimidating piece of equipment. Here is a very basic guide to setting up a mixing board for a small live show with a basic bare bones PA system pfmlures.com: K.
Apr 23, · Setting up a home theater system doesn’t have to be, though. In fact, it can be quite easy. No matter what gear you have, this guide should help you get everything set up correctly. A sound reinforcement system is the combination of microphones, signal processors, amplifiers, and loudspeakers in enclosures all controlled by a mixing console that makes live or pre-recorded sounds louder and may also distribute those sounds to a larger or more distant audience.
In many situations, a sound reinforcement system is also used to enhance or alter the sound of the sources on the.
