Surround 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 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.
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.
There 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!
Analog 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.
