DE-1 Owner’s Manual
Introduction
Thank you very much for having purchased the
Fostex DE-1.
This unit is a completely independent two channel
Multi Effect Processor that employs the A. S. P. (Fostex
Advanced Signal Processing Technology), which is
newly developed by Fostex. It provides high quality
ambient effects almost equivalent to a professional
effect processor. In addition to the typical Reverbs,
it offers 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.
Also, the DE-1 offers two operation modes as “Dual
Mode” and “Single Mode”. The “Dual Mode” works
twice as much as an independent single channel Multi
Effect Processor, which configures as 1 Input - 2
Output times two. The “Single Mode” works as a 2
Input - 2 Output Multi Effect Processor.
You can use the unit by connecting it to the AUX
Send and AUX Return of an Audio Mixer for a
recording. Also you can directly connect the output
from your musical instruments (Line Level only) to
the unit so that it will be a useful aid in your live
performance.
To fully exploit all of its many useful features and
functions, we recommend you read this manual first
before you start using the DE-1.

Precautions
(please read before use)
Power supply
* When unplugging the AC adaptor from the outlet,
be sure to grasp the adaptor. Attempting to unplug
it by pulling on the AC cable may damage the
wiring.
* It is dangerous to use any power cable that is cut
or frayed. If the power cable is damaged,
immediately stop using it, and have it repaired.
* Do not plug in or unplug the AC adaptor with wet
hands. Doing so may result in dangerous electric
shock.
* Do not open the unit or touch any parts inside.
Doing so may result in a dangerous electric shock,
and could damage the unit.
* Do not let water or other liquids, flammable
materials, or metal objects such as pins get inside
the unit. These things may cause electrical shock
or short circuit the DE-1, and damage it.
If the DE-1 should become wet, unplug the AC
adaptor from the AC outlet, and contact your
authorized service station.
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).

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 T echnology)
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.

The Details of the Preset Effects
The DE-1 has 11 preset Effect Types available on both the Dual Mode and Single Mode. Each Effect
Type further offers a maximum of 11 variations. See Operations on page 16 and 17 for how to set up
the Preset Effects. In the following list, the numbers attached to the Preset Effects are categorized
from (a) ~ (f), (A) ~ (J) and refer to the “Algorithm Reference Numbers”. They tell you how the DE1 operates internally in each Preset Effect. See page 12 and 13 for more details of the algorithm.
