Location * Avoid using the DE-1 in the following locations: * Locations of extreme low or high temperatures, or extreme changes in temperature. * Locations with excessive moisture or dust. * Locations where direct sunlight falls for an extended time, or near a stove or other source of heat. * Locations where electrical voltage varies. * Unstable locations or where there is heavy vibration. * Near strong magnetic fields (on top of a television or speaker). 3 DE-1 Owner’s Manual Digital Effect Functions The DE-1 offers high quality ambient effects by employing the A. S. P. (Fostex Advanced Signal Processing Technology), which is exclusively developed by Fostex. With the A. S. P., you can obtain an incomparably clean and high density Hall Reverb, overwhelmingly clear Room Reverb and wonderfully hi-fidelity Plate Reverb. In addition to these typical Reverbs, the DE-1 provides not only various practical algorithms such as Delay, Chorus, Flanger and Pitch Bend, but some combinations of these are also available, e.g., Delay+Reverb. You can choose 11 variations of the algorithm to obtain a maximum of 121 types of different effects according to your taste and usage. *A. S. P. (Fostex Advanced Signal Processing Technology) The A. S. P. is an exclusive new digital effect processing technology designed by Fostex. This method extracts maximum efficiency from the limited DSP power. It achieves an overwhelmingly high density Early Reflection sound and wonderfully smooth High Dump response through the H. F. A. (Harmonic Feedback Algorithm). Also, it carries out an elaborate reverb simulation with clear sounds through the H. D. L. P. (Hi-Density Logarithmic Processing), which eliminates the mutual interference between the numerous integrated delay modules and reduce the impurity and grit of the sound. *H. F. A. (Harmonic Feedback Algorithm) There is one of indispensable elements in the natural echo called “Early Reflection sound”, which is usually sacrificed in commercial reverb products in order to reduce costs. (In practice, the Early Reflection sound means the very first reverberated sound that bounces back from walls, floors and ceilings of concert halls). The entire reverb sound quality depends on this Early Reflection sound and how closely it can resemble the real echo. The H. F. A. is an algorithm that enables the effect unit to reproduce a clear and natural Early Reflection sound by applying an ideal harmonic feedback to each delay module. *H. D. L. P. (Hi-Density Logarithmic Processing) The reverb sounds consist of lots of small delay elements combined in a complex way, which are produced by many delay modules inside the effect unit. In order to obtain smooth and comfortable reverb sounds, it is very important to efficiently organize the relationship between each delay module and minimize negative mutual interference. The H. D. L. P. is a technology which applies efficient logarithmic processing to each delay module, so that they can work in the most efficient way in order to eliminate harmful reverb elements and roughness. This makes it possible to establish high density and transparent sounds. Before the practical operation, we will briefly discuss the effect functions here such as Reverb, Delay, Chorus, Pitch and Flanger, which are integrated in the DE-1. Reverb: The so called Reverb effect consists of various reflection sounds mixed together. For example, when you clap your hands in a tunnel, you will hear the sound linger even after you stop clapping your hands. This is the Reverb. The sounds we normally hear in daily life have three types of sounds mixed together, i.e., “Direct sound”, Early Reflection sound” and “Late Reflection sound”. The Direct sound means the sound directly reaches the ears from the sound source. The Early Reflection sound means the sound that comes after the Direct sound and has rebound off the wall of the tunnel up to a few times. The Late Reflection sound means that the sound rebounds many times long after the Direct sound has disappeared. Our ears normally hear the “Direct sound” -“Early Reflection sound” - “Late Reflection sound” in that order. Delay: This is the effect to add a delayed sound to the original sound. You can obtain a richer sound or completely change the original source sound by using the Delay. Chorus: This makes the one original sound appear to have many sources. The Chorus is used to widen or thicken the original sound. Pitch: The Pitch basically means the frequency of the audio. But, in the case of an effect unit, it works this way; for instance, you can amend the vocal tone by changing the Pitch lifting or dropping as much as an octave. Also, you can obtain some unusual effects by mixing the shifted Pitch sound and the original sound together. Flanger: The Flanger is one of applications of the Delay. This is used to create a sound like a jet airplane ascending or descending. 4 DE-1 Owner’s Manual The Details of the Preset Effects The DE-1 has 11 preset Effect Typ...
