It is true that the Surround speakers are the hardest to be wired. Since your receiver is from the opposite direction (somewhere near the Center speaker) you must have two cables running across your room to feed signal to the rear speakers. Of course your electrical installation may have provided for pre-installed cables inside the walls so your problems end here!

On the other hand if it is really difficult to hook up your Surrounds without causing a mess with cables, you can simply check our Wireless Amplifiers. Simply connect the wireless trasmitter to your amplifiers Surrounds output (high level or pre-amp level) and then just plug the wireless receivers with integrated amplifiers, to an outlet on the wall where your surrounds are, and connect them with small cables to your speakers. It's as simple as that. Go to the Wireless Amplifiers page for more information.

Obviously you install rear speakers without any cable crossing your room. That alone is a great benefit, ain't it? Apart from that however, the Wireless Amplifiers offer another great advantage. They relieve the burden from your main A/V receiver of powering the rear speakers, thus leaving more power and headroom for the front and center speakers to perform optimally even if their impedance is quite low.

And all that without any trade off. The sound delay inserted by the wireless transmission is totally undedected by human ear (around 2ms) and the transmission is totally noise and interference prone free.

No. The transmission along with the correction algorithms used support an interference free operation, immune to mobile and wireless phones, microwave ovens, wireless computer networks, Bluetooth devices, human body, etc. Additionally, the four channel auto-detection and auto-scanning feature ensures that a free band is always selected automatically when you are in a really 'electomagnetically noisy' environment, without you having to worry about changes switches.

Surely you can. You can use them to power up a pair of stereo speakers in your balcony or your garden. You can also use the Wireless Amplifiers to connect your iPod or mp3 player or Laptop to feed music to your Hi-Fi speaker pair without any annoying cables lying on the floor. Or you can send music to another room(s) buying some extra Wireless Receivers. The possibilities are really endless!

The Crystal Audio Wireless Amplifiers utilize DSSS (Direct-sequence spread spectrum) Wireless Digital Transmission for Class-leading, Uncompressed CD-quality signal. The band used is the ISM at 2.4 GHz. It supports a data rate up to 4Mbps. It's an interference-free transmission, immune to mobile and wireless phones, microwave ovens, wireless computer networks, Bluetooth devices, human body, etc.
