FRONT PANEL FEATURES
Input Jack - Designed to accept a standard 1/4- inch mono phone plug. For best results use a.
high quality shielded cable to connect your instrument to the amplifier. The input is
buffered and will handle standard passive, high level active, and piezo input si gnals.
Mute Indicator - light s when the Mute function is engaged , which can only by done via the
included footswitch.
Gain C ontrol - Regulates the first gain stage of the preamplifier and controls the amount of
signa l available to the system .
- 12dB Pad - Pulling the Gain knob engages a - 12dB pad. This feature is useful for basses
that have a very high signa l l eve l. The li ght is on when the pad is engaged .
Set Level/Compression Indicator - This light helps the u se r se t the appropriate amount of
gain. When set properly , the indicator should light on your loudest / lowest notes, or when
the compressor is active. We'll go over this in more detail later in the manual.
Edge C ontro l -Allows you to dial in a little vintage, tube-style distortion as you like. The
control produces a warm single - sided, even order harmonic distortion that sounds just like
the old tube heads. With the control turned fully counter-clockwise, the circuit is bypassed.
The further to the right you turn the control the more distortion you will get. The distortion
is fairly subt le at l ow input levels and is more pronounced at high gain set tings.

E nhanc e C ontrol - called the" Magic Knob" by some, this complex control simultaneously
Boosts very low bass, upper middle, and high frequencies while putting a dip in the lower
middle frequencies .
It is flat when set to its minimum level (fully counterclockwise).
C ompr ess or Bypa ss - Pulling the Enhance contro l all ows you to bypass the front end
Compressor /Limiter. The Compressor / Limiter in your unit is a fixed threshold type. You adjust
the Compression l evel by turning the gain control up or down until you get the amount of
compression you want. You may find the bypass switch useful for getting that maximum punch
when you are slapping or popping hard .
S
emi-Parametric E quali zer - Allows you to dial in a specific frequency to enhance or cut.
This feature is especially useful for upr i ght and acoustic bass guitars that h ave a resonant
frequency. Because we've incl uded a bypass switch , you can also use it to create a second tone
that is available instantaneously. (You're welcome.) The frequency is adjustable from 40Hz to
IOKHz. The level
can be adjusted+ /- 15 dB . The contro l is FLAT when the level control is at
12:00 pos ition (straight up). ON / OFF I ndicator
D.I. Sel ec tor -Allows the user to choose to send the D.l. either pre-EQ or post-EQ.
Three Band Tone C ontrol s - Divides the aud io spectrum into thr ee bands: Bass, Mid, and
Treble. The Bass and Treble controls are shelving type filters. The Mid contro l is a band pass
type filter. These controls give you a broad general control of the tone shaping.
Ma sterVolume - Controls the main stage sound level and the H ead Phone outputs .
He
adphone Jack - Accepts a standard ?inch stereo or mono headphone plug. It can also be used
as a Master Output send to slave another amplifier.
DC Indicator - When lit , shows th at the low voltage power supp lies are operating.
Main s On/ Off S witch -This switch turns the system power ON or OFF . The switch ill uminates
to i ndicate the pr esence of AC power present in the chass i s. This switch is prior to the fuse. The
light in the switch may flicker depending on local voltage cond i tions . This is normal and
nothing to be concerned about.
NO TE: The Mains Switch will illuminate even if the fuse is blown . However, the DC Indicators
will not illuminate if the fuse is blown.
IM POR TA NT NO TE: When attached, the included lighted footswitch will defeat the Front
Panel controls for the Mute to Tune and Enhance Bypass functions.

BACK PANEL FEATURES
A mplifi er Pow er Rating:
RMS output (w i th +3 dB headroom):
200 Watts @ 8 Ohms
320 Watts @ 4 Ohms
C oolin g Syste m -Your amp li fier features a the rm ostat ically controlled fan, whi ch will switc h
on when the int ernal temperature reaches 130 d egrees F. ln l ow volume s itu ations (into 8 Ohm
loads) the fan may not come on at all.
The cooling system al so features a high temperat ur e therma l safety sys tem, which will activate
a circuit if the opera ting temperature goes above 200 d egrees F. Thi s circuit will automatically
turn off the outpu t of the sys t em in the event of overheating. It will automatically reset itself as
soon as the unit cools down to a safe operating temperat ur e.
NOTE: the D.J. will continue to operate normall y even when the amp lifier is in therma l safety
mode. Only the stage sound will be lost.
IMPORT ANT NO TE: Excess i ve h eat is a Very Bad Thing and can r esult in seve re d amage to
you r a mplifier. DO NO T b ypass or di sco nn ec t any part of you r thermal safety syste m. Doing so
will imm ediately void your warran t y!
Co mbin ation P owe r Co rd Jack and Fuse Holder -The removable power cord is attached here.
To access th e fuse holder, pull the h olde r out of the top of the power r eceptac le. Your unit was
sh ipp ed with a spare fuse in se rt ed in the fuse carr ier. USE ONLY TH E SAME SI ZE AN D
TYP E FOR REP LACMENT. Us ing a fuse with a different rating than spec ified is a VERY
BAD THING and can cause damage to your amp lifier.

IMPORTA NT NOTE: 1n order to operate properly in parts of the world not listed above, your
:amplifier may require mi nor modifications. These modifications should be made by a
QUALI FIE D technician. Contact your local distributor for further information .
.Auxiliary S peak er Output - This consist I/ 4-inch jack is wired in se ri es . It allows you to
connect an additional speaker sys tem to your com bo. Pl ease note , how ever, that your combo is
designed to put its full available power i nto the int ernal speaker.
S peaker On/Off Sw itch - Th is sw i tch turns off the loudspeaker ou tpu t jacks allowing the user
to use the h ead phon es only for silent pra ctice. Room mates and neighbors may really appreciate
this feat ure , especially at three in the morning.
FX Loop (Send and Return) - These sta ndard I/ 4-inc h jack s allow you to se nd and receive
your si gnal to and from external d evices. The effects loop is positioned po st (behind) the
compressor and before the Enhance control and the tone section. This loop is at line level; do
not use instrument level effects in this l oop as the y tend to be overloaded by the higher signal
level wh ich can cause dis tortion.
Footswitch Jack - Conne ct the footswitc h here. The footswitch offers two fu n ctio ns that are
not available on the amplifier. (See be low.)
D.I. Level - Controls the l eve l being se nt from the XLR b alanced output jack. We s ugg est
sett ing the cont rol at approx im ately 12 o'clock initially. If the signal to the board is too hot , i t's
better to engage the Input Pad on your ch annel of the board than to turn it down here , if at all
possib l e. In general , it 's bett er (in terms of signal - to - noi se ratio and dynamic pr esentation) to
send as hot a signal as possible to the board. Howev er, you can adjust the s ignal level , if
n ecessa ry, so mak e s ure your so undper so n or recording engineer is aware of this capability .
G round Lift Switch -This sw i tch lifts the ground within the bal anced output system to allow
you to e liminat e excess ive noise / ground loops when connected to external systems.
Recording Out (D.T.) -Th is fu lly balan ced XLR outpu t allows you to send a pre- or post- EQ
signa l to a recording or so und rein fo rc ement mixing co n so le. We u se Pin 2 hot configuration .
Ad justing th e Master Volume contro l will not affect this send. This output is designed to us e
with phan tom powered systems. However, it never hurts to turn off the phantom power at the
board, if possible .
Tuner Out - Sends a signal to your tuner. When used in conjunction with th e Mute function ,
this allows silent tuning. Vocalists and lead guitarists love this feature.
It can also be u se d to prov i de pre-tone signa l to oth er devices such as a direct box or conso l e.The
si gnal is enough to pro vide ade quate sig na l to virtually eve ry tuner on the mark et.

Mono Pre-EQ E ff ec ts Se nd/Re tur n - These s tandard 1/4- inch jacks allow you to sen d and
receive your si gna l to and from exte rnal d evices. This effects loop is posi tion ed post (be hind)
the compressor and before the E nhan ce co ntrol and the tone sectio n. This loop is at line l evel;
do not u se instrument l eve l effects in this loop as they tend to be overloaded by the higher sig nal
l
eve l which can cause distortion.
F OOT S WIT CH F EA TUR ES
As previously st at ed, th e footswitch activates t wo fea ture s not available via the amp lifier itself_
We
th ink they both qua lify as Really Neat Things.
Mut e to Tun e - Step on this sw itch to mute eve rythin g exc ept the Tuner Out. N ow you can tune
without bothering your singer. Or the audience . N eat , huh ?
Enhan ce By pa ss - Bypassing the Enhance all ows you to create two different tones - one with ,
an d one without Enhance. Then , use this switc h to flip between the two. Even Nea ter , don't you
think?
AB OUTT H ES PEAKERS
Ede n is the only b ass amplifier manufactur er to design, engineer and build its own drivers.
D
es igning and building our own spea ker s and high -fre quency drivers allows us to create far
grea ter synergy betw ee n our drivers and cabinets than any other manufacturer can achieve. We
can create seve ral sp ea ker and/ or cabinet prototypes and then test them together to find the best
po ssible combina tion. No ot h er manufacturer has this ca pa bilit y, whic h is why no other
man u fact u re r can eq u al Eden's sound an d reliability.
We
manufac t ur e a broad array of encl osu r es to ensure the eve ry b ass i st on th e pl anet can find
the p erfect cabinets to match his or her playing style an d p ersona l tona l requirements. The E
combo line includes the fo llo wing models:

OP ERA TI NG I NST RUC TI ONS
M ec ha ni c al a nd Th e rm al I ss ues - Durin g operation, yo ur amp lifier s hould always be placed
away from so urce s of moi st ur e or h eat . Ca re s hould be taken not to obstruct the ventilation
hol es on the bottom and s id es of the unit. In the eve nt of thermal s hutdo wn, you s hould
elim in ate the ca u se of the thermal pr oblem (poor ven til ation, speaker lo ads l ower than 2 o hm s)
immediately. The s uppli ed rack ears can be u se d to install your amplifier in a conventional
equipment rack for protection durin g transportation.

El ect ri cal Co nn ect ion - The E amplifier requires at l eas t IO Amps of correct ly wired
alternat ing current for proper operation. Providing less than 10 Amps of power may result in
poor amp l ifier performance, so it's probably not a good idea to plug al l of your band's gear into
a sing le wall outlet.
, Co nn ect ion s - All instrument - level input connections (everything but the speakers) should be
made with high quality shielded cables. The use of speaker cables for input connections wi ll
resul t in excess noise. Speaker connections sho uld be made with high quality I6 gauge or
heavier unshielded speaker cables. We recommend 10 or 12 gauge cables. The use of shielde d
line
or instrument cables for speake r connect i ons can damage your amplifier. The speaker cable
should be as short as possibl e.
INITI AL SE T UP
As bassists , each of us has in our head a concept of our perfect sound. Eden amplifiers are
designed to help you eas ily achieve the sound you hear inside you. Ho wever, it's a multi - step
process as explained below.
ln order to ensure the ultimate in tone , it's important to follow the procedure outlined below _
Don't skip steps; don't jump around . Yes, this may take a minute or two , but the work is well
worth it. Once they've done it a few times, most users can do it time and again in about a minute_
lMPORTANT NO TE: B efore you plug in your unit for the first time , pl ease do the following
things. Fir st, turn the power swi tch to the OFF position . Check the back of your unit for the
correct voltage notation for your county of operation.
Once yo u've ensured correct vol tage , set the Ma ster Volume control to minimum (fu lly counter -
clockwise). Set the tone controls to the center position ( 12:00 or 0). Turn the Enhance and Edge
controls to the minimum po sition. Set the I nput Gain control to the minimum (fully counter -
clockwise). Set the Compressor to the OFF position (push the switch IN). This wil l set your
amplifier flat and with the Compresso r di sengaged. Next , plug in the power cord to the AC inlet
on the back of the unit. Use only a safe grou nd ed receptacle for proper operation at the correc fl
voltage for your co untry.
Double check to m ake certain your amplifier is set for the correct voltage in your country.
Double check that all connections and switc h es are correct for your c ho sen mode of operation.
T urn On - Once you've comp l ete d the steps above , you can plug in your ba ss and turn on the
unit (plug it in first, ok?) and Jet's get sta rted. We r eco mmend turning your system on with the
Master Volume control set to it s minimum position. This will prevent any un expected signal
from being sent to your speakers.
Se tting Your Level - Remembe r, begin with the Input Gai n, E nhanc e, Comp r essor and Master
Volume comp l etely OFF -fully counter-c l ockwise. All EQ should be set flat, that is, at 1 2:00 -

straight up.
While playing your lowest note (or loudest), slowly turn the Input Gain up until the Set Level
light begins to blink with regularity. If you go past 2 or 3 o'clock , you may engage the Gain
Switch to better match the gain of your in strument to the amp]ifier.
If you have disengaged the Compressor as we SL 1 ggested, the Set Level light will barely blink on
your loudest notes when you reach clipping in the Input stage . We recommend you decrease
gain one or two clicks to ensure there is no clipping in the system .
Once you have properly set your Input Gain, turn the Master Volume up to a comfortable
listening l evel and proceed with th e rest of the setup process.
Se tting the Co mpr essor - If you want to use compression , engage it now by turning the-
Compressor Defeat switch OFF . The compres s or light will now blink when your gain goe s.
above the compression threshold. This will general ly show up more on th e l ower notes , or when
you employ Slapping . (A properly compressed Slap sound is very cool, indeed.) If you want
more compression , increase the Input Gain a little at a time , until you achieve the amount of
compression you desire.
SETT I NG YOUR EQ
The frequencies that you'll need to boost or cut are dependent upon your instrument, play ing
style , speaker cabinets, and venue. Extreme settings of boost or cut are unlikely to be necessary
or helpful. We are frequently asked to provide suggested settings for various styles of play. We
have discovered though , that most of our endorsers tend to set their EQ generally flat , usi ng
vary in g amounts of the Enhance Control to achieve their sound. In fact, a number of our
recording artists tell us that their standard recording set - up is to have the Enhance set at
approximately 9 or 10 O'clock and the tone controls set flat. We encourage you to experiment
with different settings to obtain the sound you desire.
Enhance - Once you've set your gain , you can move on to setting your EQ, beginning with the
Enhance contro l, or Magic Knob , as some call it. The Enhance circu i try adds very low bass ,
upper mids and highs while scooping out a bit oflow middle. The more Enhance effect you dial
in, the greater the boost (and cut). As with all of our EQ contro l s, a little goes a l ong way .
Slowly bring the Enhance control up while playing. If you turn it up close to 12 :00 on the dial
and still don't have your sound , stop there. Return the Enhance to OFF or leave it at no more
than 12:00 and work with the EQ section.
Using the EQ Co ntrols - Before you begin to twiddle knobs , let's talk about a few things.
Excessive boosting of one or more EQ frequencies may cause an overload in the EQ section. If
this happens , the EQ Clip li ght will engage. This is a Very Bad Thing and needs to be corrected
immediately.

If EQ clipping occ urs, you can either dec r ease the boost or decrease the Input Gain . Remember,
too , that our EQ controls are active , and are meant to turn both ways - not just UP! Thi s means
that you can enhance a certain frequency spectrum either by boosting that frequency or by
cutting th e adjacent frequencies. This latter method has the advantage of maximizing potentia l
headroom.
lfpossible;step wel l forward of your rig to get a better idea of how you will so und in the room ;
You may be surprised at how different you sound once you step away from the speakers.
NOTE: Many players rely on the Enhance Control (and perhaps a little Midrange Massage) to
get their sound. This method leaves the Bass and Treble controls available to dial in to a
particularly diffic ult room . Just something to keep in mind , ok?
Setti ng Bass Mid , and Treble - OK , now it's time to set the EQ, beginning with the Bass an d
Treble controls. These controls cover a fairly broad frequency spectrum and a little goes a Jong
way. Adjust these controls up or down as needed. We suggest playing a few notes in various
areas of the neck so you can hear what your adjustments have done across the fretboard.
Usi ng the Se mi-Parametric EQ Control s - Adjusting the Sem i -Pa ram etr ic control set allows
you to focus in on particu l ar frequencies to achieve your desired tone. We suggest you spend
some time experimenting wi th these controls to learn more about how they can affect your
sou nd. H ere's an easy way to do that:
Begin with the frequency contro l fully counterclockwise. Turn the Level control to
approx imat ely 9:00. Now, whi le playing, rotate the frequency control to the right a little at a
time. You sho uld be able to easily hear the frequencies this first set of controls affects.
Now, cut the Level control to approximately 3:00 and do the sa me thing .
Here are a couple of tips to help you d ial in your desired tone:
For a great fretl ess tone, dial in a little ext ra at approximately 550Hz .
For extra grind for Rock and other aggress i ve music , add a little at l- l .2KHz or 2- 2.2 KHz .
Remember , though , that a little goes a l ong way. Don't over boost.
NOTE: Rememb er that the tone you get when playing alone may not cut through as well as
you'd lik e when playing with others. You may need to adjust the tone controls to achieve the
same (apparent) tone , especially in the mids and high end.
E dg e Co ntrol - If you want to add a touch of old-school style grit to your sou nd, th is is the
contro l for you. This is not a full-shred type of distortion , however. Rather , it is mean to add a
little, well, edge to your sound. This control interacts with the Input Gain ; the effect wi ll be
:more noticeable at higher gain settings. At lower gain l evels , the effect will be very s ubtl e. We
recommend you spend some ti me experimenting with this Really Neat Feature.
