A Quick Primer On Soundbars

Surround sound adds an exciting dimension to your home theater experience. However, in many instances, it’s not possible to accommodate the satellite speakers needed to create surround effects. There might be difficulties in running wires to the speakers, or perhaps there isn’t enough space to integrate them all. Without surround sound, you’re able to enjoy only half the experience. This is where soundbars step in.

A soundbar is a specially designed loudspeaker enclosure that creates a stereo effect from a single cabinet. They are much wider than they are tall. This is partly due to acoustical reasons and to get the convenience of being able to mount the speaker unit right above or below a display, usually flat panel TVs. Due to space constraints many HD TVs often have smaller speakers, leading to poor audio quality and intelligibility.

How do soundbars achieve this?

A single soundbar replaces multiple speakers. A regular surround sound system incorporates three speakers in the front (Left, Center, & Right) and 2 or 4 speakers in the back, for surround effects. A three-channel soundbar replaces all three front speakers. However, you still need the rear speakers for certain EFX.

A 5-channel soundbar can do it all-full surround sound from an easy to install a single speaker. Soundbars use multiple speaker arrays & sophisticated electronics signal processing to simulate surround effects, including the rear channels. It is truly remarkable how a single unit speaker can reproduce audio with great fidelity.

What does powered or unpowered mean in soundbars?

A powered/active soundbar is a totally self-contained surround sound system that is connected directly to your home theater TV, DVD, Blu-ray player, and video game. There are two main advantages of a powered soundbar. Firstly, there’s no need to buy and install more equipment. Everything you need is shipped in the box. This is a pretty strong advantage. Secondly, the built-in amplification and processing is specially tuned for the soundbar’s enclosure design, boosting its sound performance to higher levels.

An unpowered/passive soundbar connects to a home theater receiver, just like regular speakers, but there’s only one of them. If you already own a home theater receiver, an un-powered soundbar might make the most amount of sense. And even if you don’t already own a home theater receiver, an un-powered soundbar lets you purchase a separate receiver that may accommodate your room and your components better than a powered soundbar.

Badminton For Physical Education – What Products Can Take The Punishment!

Badminton has been an old standby for PE classes through the decades. A fantastic sport that can be played by youngsters and adults alike, badminton requires little equipment and offers an exciting workout that will improve eye hand coordination and agility.

Physical education equipment takes a beating and lightweight badminton rackets, birdies and nets are not known for their ability to withstand punishment.

While new racket materials such as titanium composites have become more prevalent there are a few standard models that are known to take a lickin and keep on racketing. You get the point!

This article will point out a few badminton racket models that physical education teachers across the country have depended on. We will also discuss badminton shuttlecocks and badminton nets that will help you run your physical education program.

Badminton Rackets:

While competitive badders through out the world may be in the market for high tech composite badminton rackets for physical education classes you should have one material on your mind steel, steel, steel.

There is no substitute for good old steel. Steel shaft, steel frame and even steel strings. Here are some popular models.

The Morley# M14539 badminton racket offers about as much steel as you can get into a racket without ending up with giant spatula.

The Morley#M14540 doesn’t feature the steel strings but it does not lack in durability. Double steel shafts keep this badminton racket coming back for more, again and again.

The Morley# M14543 badminton racket is 2 inches shorter than a standard badminton racket. Measuring in at 24 inches in length it is designed for younger elementary school badminton players. It also features a durable steel shaft and a steel frame.

Other models that are popular at the institutional level are as follows.

Carlton Attack Ti, Carlton C9750, Carlton 313, ADA 76 Smack Excel, Yonex B460 and HL 110.

Some of these models feature aluminum shafts and frames but all of these models have proven themselves in the gymnasium and are a great value. These higher end models are still available at economy prices which makes them a great purchase for high school level physical education classes were durability may be a little less of a concern and a better playing racket is more important so students can excel.

Badminton Shuttlecocks & Birdies

Here it gets a little tricky. While steel rackets are usually some of the least expensive and best for PE classes when it comes to shuttlecocks cheapest is not always best. The least expensive shuttlecocks are plastic with rubber tip and should be considered only for backyard use.

They do not offer the best flight characteristics so they will actually make the game harder as the birdie appears to have a mind of its own in flight. They are a bargain though so you may want to have some on hand just in case.

The best models have a cork tip for better pop off of the racket and nylon skirts that perform well.

As for speed my advice is medium or blue speed as this is practical for all age groups.

In the color arena yellow has become increasingly popular for youngsters as they are easier to track in flight.

My pick for shuttlecocks for PE would be one of these or a mix.

Carlton T800 Yellow Blue Speed

Carlton C100 White Blue Speed

Yonex Mavis M300M White or Yellow

All of the above are of high quality for great playability. They will pop of the strings, fly in the direction you intended assuming you know how to use the racket and they are durable enough to survive physical education classes.

Badminton Nets

A lot of school accounts purchase our PE quality badminton net or economy nets which is fine but if your net will be used indoors may I suggest the M14563 institutional net. The difference, other than a few dollars, is that the institutional model features taped sides and bottom while the less expensive models are just net.

The taped sides and bottom make the net keep its shape better for a more professional look and better playability the tape also helps the net standout more and most importantly the taped sides and bottom make the net last longer and easier to roll for storage. Believe me the extra few bucks is well worth it.

If you are using the net outside however go with the cheapest model this will stand up to the elements best and provide more bang for your buck.

This little bit of advice should help you stretch your physical education equipment budget.

Badminton is a fantastic sport and teaching it to our children in physical education classes will help build healthy adults. The sport will improve coordination, balance and agility as well as building a healthy respect for competition.

How to Approach Math Word Problems on the Pharmacy Tech Exams

The Big Secret: Don’t think about the problem until you write down all of the factors.

Sounds too easy, right? But it’s where everyone gets stuck. Start by carefully reading over the entire question from start to finish and decode the important factors. Then, go back and slowly read it again, writing down only the necessary factors. Factors aren’t just numbers, but also things like days, percent signs, p.m., or whatever will help keep things straight for you. Also, neatly write numbers below or above numbers that will be added or subtracted and set-up any fractions.

Write an Equal sign where it belongs

This is critical; the equal sign is like a trigger to our brains that we’ve been taught since 3rd grade. Now that the problem is written in terms with an equal sign in place, the light will generally go on and you’ll start working the problem. From here, the only hang-ups you may encounter are things like not knowing conversions or needing to convert to all like factors. Even if you write down the factors wrong the first time, you’ll likely see how to re-arrange them and get started.

Sloppy writing is not allowed in math:

Your success at math is contingent on writing all of the factors neatly and organized. When you come across a math word problem, the first thought that should come into your head is to grab for a piece of paper to write it out. As you jot it down, write neatly and leave yourself some space between lines.Beware: Exam writers prey on your bad habits.

When I create practice math word problems for the free practice exams, I have to think up three dummy answers. How do I do it? It may sound sadistic, but I try to consider what answers would come up if someone was sloppy. I think about things like if a factor was left out, or if someone did the equation in a rush, or their head. Exam writers who write for official exams do the same thing. After all, the exams are used to weed out unqualified applicants. If you want to pass the exam, get in the practice of writing things down completely, neatly and organized.

When you get to a question that’s a math word problem.

First, relax and know that all of the facts are in there for you to solve it. Then take a deep breath and follow these steps: Don’t try to rush or use a short-cut

Read it at least twice

Write down the only necessary factors

Put an equal sign where it belongs
