Brand new, in the original box. Manual is included.
The AADC model DD-4AX is a digital delay processor that can introduce time delays form 4 milliseconds to 1,024 milliseconds designed for hi-fi stereo system. It can be used to restore acoustics of a large auditorium to recorded programs heard in a normal-sized room.
The sound (vibration of air) produced by object for speakers in a stereo system) takes numerous paths and causes reflections the number of wich increases on an exponential function basis as the strength (amplitude)is decayed.
The model DD-4AX electonically simulates those reflections form stereo programs by a combination of a delay circuit wich generates delay of signal and an integrator wich provides a predetermined attenuation to the delayed signals.
The model DD-4AX also features two built-in sub channel amplifiers the reproduce the delayed signals form a seperate se of speakera for more spatially rich effect.
The model DD-4AX is well suited to a broad range of applications including home stereo reproduction, tape recording, radio and TV reproduction, etc.
