Nikko ATD-1 Time Delay Synthesizer

Audio Proz Inv #: 43878

Semi-professional consumer spatial delay. Rackmount. Like new in box! The ATD-1 is a simple stereo in analogue delay designed to tap off a few echo signals and create a slightly soft sounding echo, reverb for back channel. Most people who sought the ATD1 were in need of a simple, cute unit for enhancement of recorded rock guitars and vocals which it does very effectively.

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.
