Blu-ray is an optical disc format which is set to rival HD-DVDin the race to be the
de-facto standard storage medium for HDTV. The HD-DVD vs Blu-ray battle resembles
that between Betamax and VHS and DVD+RW and DVD-RW.

Currently, the major Hollywood film studios are split evenly in their support for Blu-
ray and HD-DVD, but most of the electronics industry is currently in the blue corner.

The key difference between these new players and recorders and current optical disc
technology is that Blu-ray, as its name suggests, uses a blue-violet laser to read
and write data rather than a red one. Blue light has a shorter wavelength than red
light, and according to the Blu-ray Disc Association (BDA), which is made up of,
amongst others, Sony, Philips, Panasonic, and Pioneer, this means that the laser
spot can be focussed with greater precision.

Blu-ray discs have a maximum capacity of 25GB and dual-layer discs can hold up to
50GB – enough for four hours of HDTV. Like HD-DVD, Blue laser discs don’t require
a caddy and the players and recorders will be able to play current DVD discs. Codecs
supported by Blu-ray include the H.264 MPEG-4 codec which will form part of
Apple’s QuickTime 7, and the Windows Media 9 based VC-1.

The BDA says that although blue laser discs and players are already shipping in
Japan, they won’t ship in the US until the end of 2005 at the very earliest. It is likely
that players will be very expensive initially, compared to DVD players. In Japan, they
cost the equivalent of $2000. However, as with all new technology, prices will
quickly fall – particularly as Blu-ray will be competing with HD-DVD for that space
under your TV.

Level setting, done by ear, is more art than science. It can be done using an oscilloscope but since few people have one of those laying around we’ll cover doing it by ear. Basically you want to start with the first component in the chain (the head unit) and work your way to the last component (the amplifier).

1. Start by turning all of the input level adjustment knobs (gain controls) on your components fully counter-clockwise (to their minimum setting). Set the tone controls (bass, treble, loudness) on your head unit to no boost (bass and treble level = 0 and loudness is off). If you have more than one RCA pair you will want to set each gain adjustment separately. Make sure your fader and balance controls are set to the channel you want to adjust first. This can be an individual channel if you have individual gain adjustments or a pair of channels if you have one gain for two channels.

2. Next set all of your equalizers settings (if you have an equalizer) to the center (detent) position so they produce no boost or cut. What we want is as pure a signal as possible.

3. Put in some good quality source material, preferably a CD with strong output and a clean recording. Hard rock would be a bad choice here. Try something cleaner, maybe acoustic, that you’re familiar with.

4. Turn the deck’s volume up slowly until you begin to hear distortion. When you hear it, stop and back off slightly until you no longer hear it. If you don’t hear distortion, even when the volume is all of the way up then you have a quality head unit. That’s what we’re looking for.

5. Now with your head unit at maximum undistorted volume move on to the next component. Adjust it’s input gain until you begin to hear distortion. Back off slightly.

6. Continue this process until you have all of the components in the chain at their maximum undistorted level.

7. When you reach the amplifiers you may need to wear earplugs to adjust them to their maximum level. As before, turn up the gain until you hear audible distortion. This should be audible even with earplugs in. But honestly, if you have to wear earplugs to listen the distortion level is probably not a factor

That’s it. Play some music and verify that everything sounds right. Congratulations! You’ve just learned to properly adjust the settings on your car audio system.

Technology has changed and everything has changed today. In today’s world, we get to know everything and we are becoming lazy day after the other. There was a time when people used to get excitement with physical activities but today, we get pleasure just by sitting and using internet or by listening music players. Music players have made our life pleasant and there is no doubt about it. All we have to do is switch on to our music device and lose in the abyss of rhythm.

What would we do when our music players gets damaged? We have various options and we search for parts. Similarly, there are countless iPod parts available in the market. Today, we can get screens too for our portable music devices. Technology has created waves in the world of virtual life. If the screen gets damaged, we can get it replaced as there are numerous companies that supply iPod or iphone screen.

We often get confused with two major things-repairing or buying a new device. Even when we can get new things, we still prefer repairing or installing new software or hardware in our existing electronic devices or gadgets. However, many people prefer the latest technology and we want everything best and everything that is hot and in, but if we ponder seriously over this fact, then most of the people pull them back when it comes to cost. Yes, cost plays a very important role in everyone’s life. Where there is a less price tag, people run and they lay their hands on that thing. Today, we can find a number of options as many websites offer great deals from purchasing to repairing.

There are countless parts available in the market if we really want to repair our iPod or iPhone. However, prices do differ from place to place, company to company and manufacturer to manufacturer. It is our duty to compare various price tags and then take our final decision. It is always better to repair our existing device than dumping it and buying a new one. However, if we find a new change in the market, then for sure, we can go and grab the new device with technological advancements. However, many people prefer sticking to their old gadgets and installing new software. Installing new software is now easy and we do not have to dump our old device by preferring a new one. Therefore, it is recommended that we should understand every aspect and then make our final decision.

Gadgets are hot today and everyone has this or that type. When it comes to repairing, people generally get scared because of many hidden facts. Some people think that their original parts will be replaced with the used ones or the duplicate ones. Yes, it is true! However, if we give our device to any of the authorized dealers, then there are fewer chances of getting cheated. So, before leaving our lovely device anywhere, we should take information about the store.
