INFORMATION
TO
USER
This
equipment
generates
and
uses
radio
frequency
energy
and
if
not
installed
and
used
properly,
that
is,
in
accordance
with
the
manufacturer’s
instructions,
may
cause
interference
to
radio
and
television
reception.
It
has
been
type
tested
and

the
limits
for
a
Class
B
computing
device
in
accordance
with
the
specifications
in
Subpart
J
of
Part
15
of
FCC
Rules,
which
are
designed
to
provide
reasonable
protection
against
such
interference
in
a
residential
installation.
However,
there
is
no
guarantee
that
interference
will
not
occur
in

installation.
If
this
equipment
does
cause
interference
to
radio
or
television
reception,
which
can
be
determined
by
turning
the
equipment
off
and
on,
the
user
is
encouraged
to
try
to
correct
the
interference
by
one
or
more
of
the
following
measures:
•
reorient
the
receiving
antenna
•
relocate
the
equipment
with
respect
to
the
receiver
•
move
the
equipment
away
from
the
receiver
•
plug
the
equipment
into
a
different
outlet
so
that
the
equipment
and
receiver
are
on
different
branch
circuits.
If
necessary,
the
user
should
consult
the
dealer

INTRODUCTION
The
Peavey
Digital
Effects
Processor
800
utilizes
advanced
technology
and
unique
implementation
approaches
to
provide
high
performance
digital
audio
processing
in
a
unique
affordable
package.
Its
quality,
performance
and
capabilities
are
defined
specifically
for
the
performing
musician
with
no
American
Express
Gold
Card.
The
DEP
800
System
provides
continuously
adjustable
delay
settings
from
3.12
milliseconds
to
800
milliseconds
(0.800
seconds)
with
the
best
possible
signal
quality.
A
full
instrument
bandwidth
(20
Hz
to
10
kHz)
is
available
at
all
settings
and
with
any
of
the
effects
enabled.
This
allows
for
utilization
with
a
large
number
of
musical
instrument
signal
inputs
where
a
higher
bandwidth
is
not
required.
By
utilizing
the
extended
range
of
delay
settings,
a
wide
range
of
digital
effects
including
flanging,
doubling,
chorusing,
and
slap-back
echo
can
be
obtained
through
the
front
panel
controls.
The
front
panel
controls
allow
for
the
addition
of
LFO
modulation
of
the
delay
length,
feedback
or
regeneration
of
the
delayed
signal,
LFO
modulation
of
the
output
signal
frequency
and
total
amplitude
and
phase
control
of
both
feedback
and
delayed
signals.
The
utilization
of
a
6th
order
Chebyshev
Low
Pass
Filter
for
both
anti-aliasing
and
for
signal
reconstruction
minimizes
distortion
by
providing
excellent
stop-band
signal
rejection.
This
special
signal
processing
implementation
provides
a
wide
variety
of
digital
effects
at
an
affordable
price
with
excellent
performance
specifications.

are

on
the
Digital

An
instrument
level
input
(nominally
250
mVolts,
or
-12
dBV)
is
provided
on
the
front
panel
and
a
line
level
input
(nominally
2.0

is
provided
on
the
rear

Both
inputs
are
passed
through
an
input
gain

in
preparation
for
processing.
If
the
front
panel
low

input
jack
is
used
the
rear
panel
line
level
input
jack
is
disconnected.
After
the
initial
gain
stage,
the
input
signal
is
pre-conditioned
using
a
pre-emphasis
circuit
to
provide
better
Signal-to-

characteristics
for

should

so
that
the
green
ACTIVE
indicator
is
lit
and
the
red

only

Continued
operation
with
an
“OVERLOAD"

could
cause

and
a

It
should
be
pointed
out
that
the
ACTIVE

OVERLOAD
indicators
are
located
after
the
feedback
signal
is
mixed
in,
giving
an
excellent
indication
of
any
potential
overload
condition.
The
INPUT

control
also
ultimately
sets
the
output

level.
If
the
green
ACTIVE

is
lit
and
the
red

flashes
occasionally,
the
output
level
will
nominally
be
250

(-12

and
2.0

at

To
minimize
any
problems
due
to

Analog-to-Digital
conversion
is
preceded
by
a
10
kHz,
6-Pole,
36
dB/Octave
"Chebyshev"
Low
Pass
Filter
constructed
with
precision
components
to
assure
flat
response
and
minimum
"in-band”
ripple.
The
anti-aliasing
filters
are
followed
by
a
compression
stage
to
provide
an
increased
Dynamic
Range
for
the
8-bit
Analog-to-Digital
conversion.
This
conversion
takes
place
at
a
variable
rate
depending
on
the
DELAY
ADJUST
setting
and
the
degree
of
MODULATION
which
is
introduced
as
an
effect.
The
nominal
sample
rate
with
the
DELAY
ADJUST
set
at
xl
and
with
no
MODULATION
enabled
is
40
kHz.
once
again
to
minimize
aliasing
effects
should
the
effects
be
enabled.
The
A/D
converter
components
are
matched
to
assure
the
proper
linearity
and
conversion
accuracy
for
the
Signal-to-
Noise
ratio
attainable
with
an
8-Bit
system.
The
digitized
signal
is
then
stored
in
the
memory
which
is
constructed
with
the
16K
Dynamic
RAM
(Random
Access
Memory)
providing
the
800
milliseconds
of
possible
delay.
The
Digital-to-Analog
conversion
is
provided
using
state-of-the-art
D/A
circuitry
and
corrective
equalization
to
assure
no
reduction
in
frequency
response
due
to
sampling
(SIN
X/X
windowing).
The
Digital-to-Analog
conversion
is
followed
by
another
10
kHz,
6-Pole,
36
dB/Octave
“Chebyshev"
Low
Pass
Filter
for
signal
reconstruction
and
"glitch"
removal.
A
The
processed
analog
signal
is
then
sent
to
the
output
mix
circuitry
in
both
its
in-phase
and
out-of-phase
form
so
that
it
can
be
mixed
with
the
"dry"
input
signal
and
also
sent
back
to
the
input
circuitry
as
a
feedback
signal.
The
output
signals
are
available
at
the
front
panel
low
level
Stereo
Chorus
outputs
as
both
in-phase
mixed
and
out-of-phase
mixed
signals
and
at
the
rear
panel
line
level
Stereo
Chorus
outputs.
Both
phases
of
the
delayed
signal
are
also
available
as
feedback
signals
to
either
accentuate
or
diminish
certain
portions
of
the
audio
spectrum.
The
level
of
the
feedback
signal
is
controllable
using
the
FEEDBACK
LEVEL
control.
A
5
kHz
low
pass
filter
is
available
in
the
feedback
loop
to
allow
the
reduction
of
high
frequency
noise
build-up
in
the
prolonged
feedback.
The
output
signals
are
separately
de-emphasized
prior
to
the
output
stage
in
order
to
restore
them
to
their
original
levels
after
processing.
Two
remote
controls
are
available
on
the
rear
panel
as
well
as
manual
functions
on
the
front
panel.
These
controls
consist
of
the
BYPASS
and
HOLD
controls.
The
BYPASS
control
allows
the
unit
to
be
bypassed
entirely,
the
only
active
control
being
the
INPUT
LEVEL
control.
The
HOLD
control
allows
for
the
infinite
repetition
of
all
the
signal
data
in
the
memory
without
any
degradation.
The
footswitch
control
connects
the
“tip"
to
the
"barrel"
of
the
phone
plug
to
activate
the
remote
functions.
Also
available
on
the
rear
panel
is
an
external
jack
input
for
MODULATION
control.
An
external
input
can
be
applied
through
this
jack
to
control
the
effects
from
an
external
source.
The
CONTROL
VOLTAGE
input
should
vary
within
a
range
from
0
Volts
to
+5
Volts,
and
is
internally
protected
against
transients.
The
DELAY
SELECT
and
DELAY
ADJUST
controls
are
utilized
to
select
the
range
of
the
delay
desired
and
the
exact
value
of
the
delay
or
effect.
The
number
at
each
setting
of
DELAY
SELECT
indicates
the
maximum
amount
of
delay
for
that
range
in
milliseconds
(mSec).
The
DELAY
ADJUST
varies
the
amount
of
delay
within
that
range
from
approximately
0.5
to
2.0
times
that
range
setting.
Thus
a
4-to-1
range
is
available
for
each
range
setting.
The
MODULATION
controls
are
also
available
as
front
panel
manual
controls.
The
MODULATION
controls
consist
of
the
MODULATION
SPEED,
which
varies
the
LFO
modulator
frequency
from
0.1
to
10.0
Hz
and
the
MODULATION
DEPTH
which
varies
the
distance
through
the
memory
that
is
traversed
by
the
modulation.
By
adjusting
the
MODULATION
DEPTH
and
the
DELAY
ADJUST
controls,
sweeps
of
the
signal
spectrum
of
up
to
4-to-1
can
be
accomplished.
Due
to
our
efforts
for
constant
improvement,
features
and

are
subject
to
