Best Components to Look For In a Home Theatre?

A home theatre is an exciting entertainment option that provides a redefining listening and viewing experience. It allows you to enjoy all the experiences of a movie hall without the hassles that come along with it, like standing in the long line, expensive tickets, expensive food, beverages charges, etc.
But, there is a catch. A home theatre is only as good as its components. To reap its full benefits, you need to combine the right and suitable parts of a perfect home theatre system. One poor purchase decision will drastically reduce your viewing experience and value of your system. Let us go through some important components that you should consider while building or modifying your home theatre system.

home theatre system

Home theatre room

The room where the home theatre will be set up is one of the most important components of the operation. The position of entry points, window locations, the shape of the room, etc. all play a role in getting your home theatre system together.
You can break the sound barriers in your house by customising your sound system the way you prefer.  For a dramatic cinema experience at home, try some advanced sound system such as Heos Home Theatre System and set it up according to your home architecture.  Consider the positioning of the furniture according to how many people will be present in the room.

TV and Projectors

Choosing between a TV and a projector is ultimately a personal preference. Both are great in terms of a home theatre. But, in the end, some rooms may not be equipped to host a projector, while some can easily be accommodated in one. It is entirely up to you. Below, you can check out both the options and decide for yourself:

TV

1. TV Components

One of the most important components of a good home theatre set is your television set. It all depends on the lighting system of the room where the home theatre system will be installed. For a dimly lit or dark room, an OLED or plasma TV is recommended while for a normally lit room, LED or LCD will work out just fine.
The screen size of the TV will directly reflect on your immersive experience. Hence, you should consider at least a 50-inch screen TV for a great experience. Thanks to modern TV sets, a large screen set won’t occupy much space. That is because the size of the bezel has become thinner in the past few years. Some screen sizes can be compared below:

65 inches-90 inches screen size: It is perfect for media rooms if you totally want to immerse yourself in watching your favourite movies or sports.
50 inches-64 inches screen size: These large screen TVs are perfect for a large living room and provide a great visual impact.
33 inches-49 inches screen size: This is a versatile size that can be fitted in any bedroom or an average-sized living room.
32 inches or smaller screen size: This is a decent size for casual viewing areas like kitchens, dorms, and bedrooms.

The next most important aspect of a TV is the resolution. The higher the resolution, the better the picture quality. The three suitable resolutions for a home theatre system are:

4K Ultra HD (2160p): 4K HD TV sets offer the best resolutions in the market today. The picture quality is four times better than 1080p with a stunning detailed and clear picture. This resolution allows you to immerse yourself in the ultimate viewing experience. You also have the option of up-scaling the definition according to your viewing comfort.
Full HD (1080p): It is the most common resolution available. You can easily watch TV programs and Blue-ray films at the highest detail level. Most videos on YouTube use this resolution.
HD (720p): This resolution provides a decent HD quality for movies and TV shows at affordable prices. It is generally used for small TV sets.

2.Projectors

For a larger-than-life gaming, sporting, and cinematic experience, a projector is undoubtedly required. It allows you to magnify the projections by many times without compromising on the quality of the image. For the best performance, you need to choose a projector that has the right amount of lumens (light output).
The brighter the room, the more lumens will be required. Along with a projector, you will also need to buy a high-quality screen that contains materials for optimum reflection. Good reflection maximizes the image brightness.

Theatre Audio: Sound Bar or Home Theatre in a box

Audio plays an important role as well when it comes to setting up a home theatre room. Investing in good quality speakers allows you and your guests to completely immerse in a game or movie.

1. Sound Bar
A good soundbar system offers a convenient alternative to placing several small speakers all over the room. All you need to do is place a single bar below or in front of your TV set or mount it on the wall. Most sound bars come with separate wireless or wired units for a rich bass sound that can be set up far away and still make a powerful impact. These sound bars can include up to 6-8 separate speakers.
2. Home Theatre in a box
These systems provide you with everything that you need for a great surround-sound audio in a single box. The most common system used all over the world is the 5.1-channel surround sound system. The setup would typically look like:
The left and right speaker on either side of your TV set for special effects and soundtrack.
The centre-channel below or in front of your TV set for on-screen action like dialogues.
Two speakers on the rear for directional and atmospheric sound effects.
The sub-woofer in the corner or off to the side for deep bass effects.
You can also go for a 7.1 surround system, where you get extra side speakers for more surround sound effect. All of these sound systems include either a Blu-ray player or a dedicated A/V receiver. It is up to you if you don’t need any of these two and choose only the speaker system package.

Planning in advance is the best way to achieve your dream of a perfect home theatre system. Determining the room or where to place your speakers may seem like a dry job, but it will make all the difference once you sit back and let the film roll!

What Defines A Good Plasma Torch?

As we know, the matter is of three types – solid, liquid, and gas. Matter changes from one state to another by the introduction or reduction of energy like heat. Now, plasma is the fourth type of matter. If heat is applied to the liquid, it changes to a gaseous state. If the gas is again heated, it ionizes and becomes conductive to electricity and becomes plasma.

 

How does a plasma cutter work?

A plasma cutter uses this electrically conductive gas to transfer energy from a power source to a conductive material, thereby resulting in faster and cleaner cutting process than oxy-fuel. A plasma torch produces a high-temperature plasma jet of nearly 40,000°F which enables it to cut efficiently through hard surfaces. Plasma jet is created when transmission of energy takes place to a metal conductor from a power source, and gas like oxygen or just air is passed through a very narrow opening in a nozzle resulting in a plasma arc formed. The metal changes into its molten state and is discarded merely off.

A plasma cutting system consists of the following components:

1.Power supply

This converts three-phase or single AC line into a constant and smooth DC voltage that ranges from 200-500VDC. The voltage is responsible for maintaining the plasma arc throughout the cut and regulates the current output based on the thickness and the material type that is being processed.

2. Starting arc console

The spark inside the plasma torch is created by the ASC circuit that gives out approximately 5,000 VAC AC voltage that is used to generate a plasma arc.

3. Plasma Torch

The primary function of the primary torch is to provide proper cooling and alignment of the consumables. The main consumable part required for plasma arc generation are the nozzle, swirl ring, and the electrode. In most cases, an extra shielding cap may be used to improve the cut quality more, and all the parts are kept together by outer and inner caps.

Most plasma torches can be categorised into two types – precision and conventional torches.

 1. Precision torches

High current density or precision plasma torches are engineered and designed to produce the highest and sharpest quality cuts achievable. There are tons of cutting guide available from distributors like Tanjant Tools instructions and using guide.  The consumable designs and the torch are more complex and additional pieces may be required to shape and constrict the arc further. This plasma’s amperage is about 40-50K amps per square inch and several gases like nitrogen, highly pure air, and oxygen is mixed with a nitrogen/argon/hydrogen mixture to be used as a gas for the best results on several types of conductive materials.

2. Conventional torches

These plasma torches mostly use shop air as plasma gasses. The nozzle’s orifice defines the shape of the plasma arc. With 12-20K amps per square of amperage. All sorts of hand-held systems use this kind of plasma torch and at some mechanised applications as well.

 Components of a plasma torch

Putting together a decent plasma system can be a difficult task. It all begins with a machine that generates the stream of plasma, the X-Y table, ventilation system, software, and a CNC.
The X-Y table includes drivers and motors that provide accurate and coordinated motions for several types of torches, be it oxy-fuel or plasma. Earlier, the main application of the X-Y table was limited to shipbuilding and heavy equipment industries. These machines were designed to be strong enough to stand for several decades to come and to produce tons of metal parts with minimal maintenance. Today, there is no shortage of X-Y table styles.
Next, every X-Y table must have the CNC component. It is the brains of the machine that converts the cutting program into electrical instructions that control the cutting speed and direction. The CNC also provides information and instructions to peripheral equipment, height controller, and the plasma cutter. The industrial-grade computer’s internal motion and machine-control software controls take orders from the CAM software (manufacturing industry software that is used to design and deals with the machine’s capability to work on that task) and machine operator and convert these orders into functions by controlling the drive systems. These industrial CNCs are developed to withstand the rough work environment like smoke and debris from welding and cutting processes, machine and electricity interference vibrations from machines, etc. Drive electronics like steppers are cheaper and more straightforward than servo systems and are often controlled by laptop and computers. Servos are more intuitive for machine operators as they use feedback encoder to the CNC, thereby resulting in fewer chances of lost positioning on the cutting table in an event like cutting interruption, power failure, or tipped-up part.
Mechanical components of a plasma torch include some moving parts like torch height control, torch carriage, and gantry. For large industrial machines, all these components are heavy-duty and sturdy. The heavier the device, the more powerful drive motors and the weight-bearing systems are. Modern mechanical parts provide excellent precision have more extensive torque range and speed that is beneficial for extremely slow or fast speeds.
Automatic height is an optional feature that is well rewarding in most cases. Effective cutting via a plasma torch requires three modes of height – two for cutting and one for piercing. This maximises the cut quality and consumable life of the plasma torch. The piercing torch plays the most critical role when it comes to cut quality and nozzle life. The system advances the plasma torch till it finds the surface of the material you wish to cut and retracts to a proper height. One wrong pierce can affect the cut’s overall edge quality dross, and angularity permanently.

Conclusion

Plasma torches have come a long way the heavy first-generation counterparts to a machine that looks like a child’s toy today. Today, these machines come in different models and styles that are suitable for a variety of operations. New technology, ranging from televisions to automobiles, have gone through an evolutionary period. Such is the case with plasma torches as well. These machines have become more reliable, capable and smaller and ready to withstand the harsh conditions of the industry.
