GENERAL DESCRIPTION
The ED™ 100 is a self-contained amplification system which features inputs, equalization, and monitor
capability specifically designed for use with electronic drums. The ED-100 will deliver 65 watts RMS into its
heavy-duty 15" Scorpion? speaker. Peavey design engineers have also included a special constant-directivity
horn for faithful reproduction of high frequency signals. To protect the speakers and to prevent clipping
distortion, the ED-100 features Peavey's patented DDT" compression circuitry.
Since the ED-100 has been designed specifically for use with electronic drum systems, it offers many features
not found on other amplification systems. Independent monitor mixing, four-band active EQ, and complete
effects patching capability allow the drummer to realize maximum potential from today's electronic drum
systems,
The ED-100 is built to withstand the rigors of a night-after-night touring environment. The cabinet is con-
structed of%" wood and is covered with the heaviest available 34 oz. Tolex®, Ruggedness is enhanced by theuse
of heavy steel corners and a steel-reinforced carrying handle. Internally, the ED-100 features chassis construc-
tion of heat treated aluminum alloy and utilizes the finest components available.
Although the ED-100 incorporates many sophisticated features, its operation is relatively simple. In order to
quickly familiarize yourself with the ED-100, and to avoid potentially hazardous or damaging situations, please
read this operating guide carefully and completely and keep it handy for future reference.

BASIC SETUP AND CONNECTIONS:
The ED-100 features two channels which differ in input equalization.
The normal channel is essentially “Yat” (no input equalization) and is
designed primarily for amplification of bass drum signals. The bright
channel is equalized to enhance high frequency signals and is designed
primarily to accept signals from the snare drum and tom-toms.
Most electronic drum system mixers provide two outputs for adjusting
the mix of individual orum signals. To interconnect ihe drum mixerto the
ED-100, use two high-quality shielded connecting cables. Connect one
‘end ofeach cable to each of the mixer’s outputs. Connect the other end of
‘each cable to a channel input ofthe ED-100. Then adjust the drum system
mixer to route individual crum signals to the eppropriate channel of the
ED-100.
Since individual drum system manutacturers differ in mixer contgura-
tion, acomplete discussion of mixer adjustments is beyond the scope of
This manual. Consult ne owners manual of your drum system for specific
instructions regarding channel assignments. A basic mix for use with the
ED-100 might look like this:

FRONT PANEL FEATURES:
CHANNEL INPUTS (AE)
As discussed in the Basic Setup Section, the Channel Inputs
receive signals from the drum system mixer outputs. These
inputs are high impedance and will accept signals over a wide
dynamic range.
CHANNEL GAIN CONTROLS (B,F)
The Channel Gain Controls allow individual volume adjust-
ments of each incoming signal. Adjusting the individual Chan-
nel Gain Controls will affect both the overall loudness of the
ED-100's output and the balance between channels. Some
experimentation will benecessary to determine the best overall
balance between channels. Regardless ofthe typeof electronic.
m system used, setting of the Channel Gain controls above
12 o'clock) is not recommended. Setting the Channel Gain
controls above "5" may result in unwanted distortion and/or
premature engaging of the DDT Compression Circuit (see the.
DDT Compression Section for further information).
MONITOR CONTROLS (C,G)
Each channel is provided with a Monitor Controland monitor
preamp. These controls are completely independent o! the ED-
100's internal signal flow; signal from these controls is routed
directly to the monitor jacks on the rear pane! (see the Monitor
Jacks Section for further information).
EFFECTS PATCH JACKS (D,H)
Each channel is provided with a stereo-type Effects Patch
Jack. These jacks are used with external devices to provide
independent effects loop capability for each channel.
To patch an effects device into a channel, a stereo "Y" cord
should be used. First, turn the Channel Gain Control to its "0"
‘setting, Insert the stereo plug inio the effects patch jack. insert
the "Tip" plug into the effects input jack. Insert the "Ring" plug
Into the effects output jack. Then slowly increase the Channel
Gain Control setting until a satisfactory level has been
achieved. Note that all signals in a channel (except monitor.
signals) will be sent through any effect patched into that chan-
nel. Also note that the Effects Patch Jacks occur in the signal
path before the equalization stage (pre-EQ). Therefore, any
effects signal will be altered by changes in the equalization
controle (soo the Equalization Controls Section for further
information)
EFFECTS DEVICE
EFFECTS PATCHING USING EFFECTS PATCH JACK
EQUALIZATION CONTROLS (1)
The ED-100is equipped with four bands of equalization, each
adjusted by one of the four Equalization Controls. These con-
trols are "stacked" on the front panel. The inner knob on the left
stack is the Low Frequency Control, while the outer knob is tor
Low Mid frequencies. In the right stack, the outer knob regu-
lates High Mid frequencies, while the inner knob is the High
Frequency Contro.
The ED-100 features active equalization, which means that
frequencies within any band may be either cul or boosted.
Setting any Equalization Control to "0" delivers a "flat" (unal-
tered) frequency response lor that band. Rotating an Equaliza-
tion Control clockwise will boost frequencies within that band,
while rotating counterclockwise will cut that band's frequen-
Extreme care should be taken when boosting low frequen-
Low frequencies consume a disproportionate amount of
amplifiers power, and overboosting low frequencies may
lead to loss of headroom (amplification capability) and to pos-
sible speaker damage. Extreme boost of any Equalization Con-
trol should be avoided to ensure quiet operation.
MASTER GAIN CONTROL (K)
The Master Gain Control regulates the totalamplificationand
headroom of the ED-100. in normal operation, the Master Gain
Control should be set at or near "10" to allow maximum head-
room and dynamic range and to prevent distortion.

HEADPHONE JACK (L)
‘The Headphone Jack allows the use of any stereo headset
with the ED-100. When a plug is inserted into the Headphone.
Jack, the amplifiers internal speaker automatically is discon-
nected, creating a totally private rehearsal environment. Note
that the headphone system will not work with headsets
equipped with a mono phone plug.
DDT" COMPRESSION CIRCUIT AND COMPRESSION LED
M)
Une ED-100 utilizes Peavey's patented DDT (Distortion
Detection Technique) Compression Circuit to virtually elimi-
nate the possibility of clipping distortion in the power ampliifer
and speakers. The DDT Circuit performs its function automati-
cally and is not adjustable. The DDT Circuit will not engage
until the ED-100 is utilizing all available output power. When
this occurs, the Compression LED will light. In normal playing,
the ED-100 should be set so that the Compression LED lights
only on very loud passages.
If the Compression LED remains constantly lit, this indicates
that the Channel Gain and/or Master Gain Controls are set too
high, or that too much boost equalization is being used. In this
iation, control settings should be reduced until the Com-
pression LED fires only intermittently. The Compression LED
will sometimes illuminate when the ED-100 is turned on. T!
normal and does not indicate a malfunction of the ampiifier.
GROUND SWITCH (0)
The Ground Switch is a three-position rocker switch which
should normally be operated inits center or "0 position. Occa-
sionally, a situation may arise in which noticeable hum or noise
comes from the ED-100's loudspeakers. If this should occur,
switching the ground switch to either positive (+) or negative (-)
should eliminate or minimize the noise. If hum or noise prob-
lems persist, consult your Authorized Peavey Dealer or a quali-
fied service technician. NOTE: THE GROUND SWITCH IS NOT
FUNCTIONAL ON 220/240 VOLT EXPORT MODELS
ON/OFF SWITCH AND POWER LED (P.N)
The On/Oft Switch is a two-position rocker switch which
provides AC power to the ED-100. When the switch is in the On.
position, the red Power LED will illuminate showing that power
is being supplied to the unit.

REAR PANEL FEATURES:
LINE CORD (Q)
For your safety, the ED-100 is equipped with a three-wireline
(mains) cord and a three-pin AC plug. It is not advisable to
remove the ground pin under any circumstances. If it is neces-
sary to use the ED-100 without proper grounding facilities (as
when only two-wire AC service is available), a suitable ground-
ing adaptor should be used. When the ED-100 is used with
properly grounded AC receptacles, shock hazard is greatly
reduced, as are hum and noise.
MONITOR JACKS (R.S)
Two Monitor Jacks (one for each input channel) are provided.
Signal to these jacks is controlled by the Monitor Controls (see
the Monitor Controls Section) and is not affected by any Gain or
Equalization Controle. Signals from these jacks may be used to
feed monitor amplifiers, sound reinforcement systems, record-
ing consoles or other equipment.
PREAMP OUT AND POWER AMP IN JACKS (T.U)
The Preamp Out and Power Amp In Jacks provide another
form of effects patching within the ED-100. Effects may be
patched between the preamp and power amp according to the
following diagram. Be sure to use high-quality shielded cables
when connecting any effects device with the ED-100. Connect-
ing an effects device at the Preamp Out and Power Amp In
Jacks differs in two ways from effects patching discussed ear-
liorin the Effects Patch Section. First, any effect patched at this
point will affect all signals in both channels within the amplifier
[except monitor signals). Secondly, this effects paich point
occurs after the ED-100's equalization stage (post-EQ). In
experimenting with effects patching, you may note differences
in the operation ofan effects device depending on its location in
the signal path.
LINE/RECORDING JACK (V)
The Line/Recording Jack provides a means of sending a low
impedance signal to the mixer, recording console or additional
amplifier. Signals appearing at this jack are post-EQ and con-
tain information received from both input channels.
