Audio Video Receiver

Thursday, September 3rd, 2009

Audio-Video ReceiverSurround receiver is a shining example of hk’s long-standing tradition of mating useful, creative features with outstanding sonic quality. Rear-panel inputs and outputs are all clearly marked, and–unlike some surround receivers–most essential functions can be accessed through front-panel controls rather than merely through the remote.

The remote can control many other non-harman products in addition to the avr65, but it takes a careful reading of the well-written manual to set this up. The avr65 automatically senses the type of digital surround encoding in use and adjusts to accommodate it. One caveat about the digital processing is the 48khz limitation on the digital input. To further “future-proof” the avr65, harman has designed the model with two other unique analog features: high current capability (+/- 40 amps) and ultrawide bandwidth (8hz – 80khz).

Because loudspeaker impedance (the inherent resistance to the incoming voltage) varies with frequency, the amplifier may need to deliver, at moments, up to six times the current load required for the speaker’s impedance rating; the avr65′s high current capability does just that. Harman’s ultrawide bandwidth offers linear frequency response to around 80khz, well beyond the range of human hearing. This reduces undesirable phase shifts within the audible spectrum and increases “headroom,” the amplifier’s ability to reproduce complex, dynamic transients (such as cymbal crashes) with greater accuracy. The benefits of these features came through clearly in our testing.

The Blue Ray Player – Future Disk Player

Wednesday, July 22nd, 2009

blue ray playerThe Blu-ray disc is an optical storage disc used for storing HD information: movies, games and any other pieces of data. Its main competitor in this area was the HD DVD. A major role in this confrontation was played by the launch of the PlayStation 3 console in 2006, which supports the “blue” disc and which also acts as a Blu-ray disc player.

But the novelties brought about by the Blu-ray disc and implicit by the Blu-ray technology doesn’t stop at that. If a HD DVD can hold up to 60 GB of information – that means 15 GB per layer, the “blue” disc has a limit of 200 GB and the possibility to store 25 GB of data per layer. Up to now was released on the market a Blu-ray disc with a maximum capacity of 50 GB, but for the future it is planned to make available a “quad-layer” version – with 100 GB and even a 10 layer disc with the capacity of 250 GB.

For the time being the “blue” disc is sustained by various large companies and by the biggest movie studios: MGM, Walt Disney, Warner Bros, Buena Vista and many others. The good news are that the price of a player has dropped from 3800$ (one of the first available Blu-ray players) to a medium price of 200$ and that now are available many models of “blue” players produced by different companies, such as: Pioneer, Samsung, LG, Loewe, Panasonic and (of course) Sony.

The Best Wireless Surround System

Thursday, June 25th, 2009

wireless_speaker_systemThere are a growing number of options for anyone interested in purchasing a wireless surround sound system for their home. By being informed about the technology and terminology, you know what to look for and will be able to get the best quality at the best price.

The technology doesn’t yet exist that will allow high-performance speakers to be completely without wires, but it has been making strides. The front speakers are typically wired and this setup is saved for the rear ones. These speakers still need wires to be plugged in for power. Although some battery operated ones are on the market, they do not deliver high quality audio.

Although there are still some wires in a these systems, it is still more convenient than traditional speakers that are difficult to set up. It saves you from having to secure the wires so they won’t be tripped on or unsightly. It’s also good for someone who wants their home theater in the center of a room because they are unable to run the wires along their walls.

There are a growing number of options for anyone interested in purchasing a wireless surround sound system for their home. By being informed about the technology and terminology, you know what to look for and will be able to get the best quality at the best price. A wireless surround sound system is capable of delivering superior sound and an easy set up that will fit any size room.

Portable Power – In Case You Needed

Friday, June 5th, 2009

Portable PowerThere are many situations where a portable power charger would serve a great purpose, such as residential and commercial situations. In fact using a portable unit for power could lessen the cost of power consumption and hence help in cost cutting during times of recession. You no longer have to worry about your phone running out of charge while you are out doing your shopping with the kids!

Portable power units come in different capacities to suit the individual need, it is a total solution for the whole family or work space as it not only operates portable refrigerators, it can also be used as your laptop charger, mobile phone charger, portable radios and DVD players alike. Every industrial unit and business establishment must have a portable power unit to meet sudden emergency situations such as power shortages. It is a necessity and a one time investment.

If for one day the power generation stops, the whole world would come to a stand still. Many millions will be lost in business and much damage will be done economically. Scientists are also ready to face power shortages or outages as they have discovered a huge range of alternate power units or portable power units.

HDTV Connections

Saturday, May 23rd, 2009

HDTV ConnectionsAnalog connections are comprised of radio frequency (RF), composite video and S-video connections, which can be used to connect cable boxes, VCRs, DVD players, antennas and some game consoles, of which S-video has the capability of delivering the highest video quality. There are also analog audio connections for older audio receivers and stereo components.

Check for HDMI connections, in particular, since these allow you to get superb video and audio quality from most HD sources, including HD cable boxes, Blu-Ray players, surround sound speakers, HDTV tuners and newer game consoles.

For Your Speakers

To enjoy the superior sound quality offered by your HDTV, it is recommended that you connect external speakers, whether a pair of stereo speakers or four, six or seven surround sound speakers. You cannot connect them directly to your HDTV, though. Rather, you have to connect them first to the AV receiver that comes with the system then connect the AV receiver to the HDTV.

For Your Computer

You may also want to use your flat screen HDTV as your computer monitor. If you do, you will need to get a high quality video card for your computer then connect the CPU to the HDTV via the output provided on the card.

For Your Game Console

You can also enjoy playing video console games on your flat screen HDTV. Wii game consoles have component video outputs while Xbox and PlayStation consoles have HDMI for superior video quality.
