4 Reasons To Calibrate Your Video Equipment
-Colour matching between sources is incorrect with current HDR content, therefore a calibration is required in order to ensure proper HDR colours.
-Calibration unleashes the maximum performance and colour accuracy from your TV or Projector.
-Calibration matches your screen and projector to each other, ensuring perfect colour reproduction.
-Accurate colours, achieved through calibration, result in maximum fidelity and naturalness to the image.
A calibrator’s first job is to ensure that your television is set up correctly. This involves checking that cables are adequate and connected properly, that sources output the correct resolution, etc. Using a setup disc or a test pattern generator, the calibrator then goes through the TV’s settings to make sure it looks its best. This process includes correctly setting the contrast and brightness controls to make sure the TV is as bright as it should be for your viewing environment, and that it has the best black level possible without obscuring shadow detail.
The goal of the colour temperature adjustment process is to bring your TV as close as possible to the D6500 standard used throughout the film and TV industry. When this adjustment is done correctly it ensures that your TV looks as close as possible to what the director of the movie or TV show intended. Our trained professionals check your TV’s settings and setup, and fine tune its colour temperature to be as accurate as possible.
A correctly calibrated TV will likely look more pleasing to the eye and, depending on its light output after the calibration, may draw less power and last longer. The calibration process produces a better picture than the default settings while the image looks more “natural.”
The goal of calibrating your home theatre’s audio system is to achieve a smooth, even frequency response at the primary listening position. In addition, if the audio system was designed appropriately relative to the dimensions of your home theatre room, it should also perform well at the other seating locations
5 Reasons For Audio Calibration
The frequency response of a system is a measurement of the relative levels of all reproduced audio frequencies.
Dynamics is simply defined as the difference between the softest and loudest sounds reproducible by a sound system.
An audio system should reproduce virtual images of each recorded sound presenting the listener with its apparent source location in a three-dimensional space.
Acoustic focus is defined as the ability to precisely locate each reproduced sonic cue or image in a three-dimensional space.
Clarity is the prime acoustical quality because its perfection depends on the successful attainment of all other goals. Dialogue intelligibility in movies is of paramount importance, but one must also be able to understand musical lyrics, detect quiet background details and sense realism for acoustical sounds. Elements that affect this goal are varied and include equipment quality, room reverberation levels, ambient noise levels, and listener position among others. Clarity is paramount in defining the performance of a home theatre system.
Room acoustics is the broad term that describes how sound waves interact with a room. Each room, and all the objects in it, will react differently to different frequencies of sound. A speaker will sound differently in different rooms. For example, imagine an empty room with hardwood floors and bare drywall. Lots of echoes, right? Now imagine the same size room with lush carpet, lots of bookcases, a big plush sofa, and thick draperies. Quiet and intimate. These are the fundamental extremes of room acoustics, and the ideal-sounding room is somewhere in-between.
This can be accomplished electronically or through physical adjustments to the room. However, there are a few terms which are important to understand first.
First Order Reflection
First order reflections are the first locations where sound reflects between your ears and the speakers. This is often a wall, the floor, and the ceiling at a point roughly mid-way between the seating position and the front of the speaker. When tuning a room, the first reflections are commonly treated with either diffusion or absorption. Absorption can be simple -using everyday items like drapes, fabric walls -or more sophisticated such as purpose-built acoustical treatments. Installation of treatments on these locations can be dramatically beneficial to an audiophile or home theatre installation.
Room Correction & Tuning
Room tuning is a way to describe the art and science of adjusting room acoustics using physical and/or electronic means for audiophile and home theatre rooms. There are many ways to tune a room, but the most common are using physical pieces of room acoustic treatment (like absorption & diffusion, mentioned above), and through digital means, using some sort of digital EQ
Diffusion is an aspect of room tuning with the idea of breaking up standing audio wavers in an audiophile or home theatre room. At a basic level, smooth surfaces are more reflective than rough ones. The rough surfaces disperse audio better, while the smooth ones (such as glass, smooth walls, or stone floors) create more echoes and reflections. A brick wall is an example of a surface that provides diffusion in a real-world audio environment. RPG’s BAD panels combine a mix of absorption and diffusion, normally covered by a fabric wall.
Bass traps are acoustical treatment devices used in room tuning and are designed to absorb the long bass wave energy that often gets energized in the corners of a home theatre room. They help clear up that “clogged-up” or “muddy” bass sound, thereby making a room sound tighter, louder and more in control on the low end. Note: A room with all-absorptive surfaces will not be a good-sounding room. A balance of diffusion and absorption is required to achieve a good audio environment.
The combination of strategic speaker placement and acoustic treatment will elevate your listening experience. Early reflection control combined with careful speaker placement will result in a transparent sound stage with tight, focused imaging. Smart choice of listening position, speaker placement, and bass absorption will produce a tighter, more even low end with better bass extension.
An acoustically treated room makes it easier to emotionally connect with your music, or immerse into the movie world! You will experience a new level of depth and clarity, letting you hear crisp details and the full dynamic range in high fidelity.
Aeronautical Equipment Calibration
Image clarity is crucial for airplane on-board monitors. Conformance to industry standards can be achieved through periodic service and calibration.
Medical Equipment (DICOM) Calibration
When analyzing the output of medical imaging procedures, the image itself could present with very small luminance differences between the area of interest and its surroundings. In addition, the low-level shades of gray may be particularly hard to distinguish. Properly calibrated medical grade viewing stations allow for correct interpretations of the images displayed.
