NEC AVD700E

Audio Proz Inv #: 8362

Surround processor, multifunction video processor

Be aware, this is not an amplifier but a rather remarkable, super audio quality 4 channel processor. It has 2 channels in and 4 channels out which allow the unit to create delays and acoustic ambiance enhancements from the original 2 channels. This machines best attribute is to extract the natural ambiance (reverberation) from the stereo image and place it in the back channel as well as adding user-adjustable delay time to further enhance the natural surround/large room effect. Its a device for the purist audiophiles who are not looking to substantially alter their sound but rather enhance their stereo to 4 properly placed speakers. Feel free to call for more info if you are interested.
