Introduction:ENGLSoundWizardmodule,typeZ-16
The ENGL Sound Wizard module, also called or for short, is an
add-ontone-tweakingtoolthatletsyouvoice theampwithsurgicalprecision.
The optional Sound Wizard module is mounted on a special rear panel that you can
installin backoftheENGLINVADER IIwhenneeded.
When the module is activated, 96 rocker switches on 16 DIP switches that sit on the
SWM'scontrolpaneltakecontrolofcertain sections of the amp's circuitry. The rockers'
settingsre-voice the guitar'ssignalinthe amp,therebyshapingyoursound.
Installing the Sound Wizard module is a fairly simple matter, and requires no special
technicalskills. All ittakesisa screwdriverandafewminutes ofyourtime.
Sowhat does thisuniqueSoundWizard module doforme?
Every guitar player has some very specific ideas about what constitutes great tone.
Most guitar amps offer various knobs, switches and buttons that serve to adjust the
variouschannels' fundamental sound. Other control features address the various gain
stagesand operating modesthataffectthe amp'ssound.
ABright switch, for example,bringsupacertainfrequency range –thetopend–when
itis enabled. Of course, it's entirely upto whether you use it. If youlike the way it adds
sparkle to your signal, go for it. But if it's of no use to your style, then you can safely
ignore it. Now that's what sets our SWM's little rocker switch apart from a built-in
Bright switch. What good does it do you on the amp's front panel if you'll never have
causeto useit?
Sound Wizard SWM
ENGL developed this Sound Wizard technology to give discerning guitarists
unprecedented freedom to fine-tune their tone as they see fit. Let's look at another
example: Imagine how handy a Bottom Boost switch would be if you wanted to beef
up a crunchy rhythm sound. It would let you tweak your tone with some added lowfrequencypunch.
With the , all you have to do is select the appropriate setting on the
module'sLowEndorLowMidrangerockerswitchtoachievepreciselytheeffectthata
front-panelBottom Boost switchwouldhaveon the amp.
Andthere's more toenjoy:
The Sound voicing function on the INVADER II has two settings, Off and On (disabled
andenabled). The red LED abovethebuttonontheamp lights up whenthisfunctionis
enabled. This gives you two voicing options for each of the eight fundamental sounds
provided by four channels with two gain stages each. If that's not enough sonic
firepower to voice sounds as you see fit, then you can also adjust several frequency
ranges at the same time by setting more than one of these rocker switches, which
operate selectively. For example, you could configure clean sound A for Channel 1 in
Low Gain mode by simply setting rockers #2 and #4 ( and ,
respectively).Thenyoucould configure clean sound B forChannel2in Low Gain mode

by setting rockers #1 and #5 ( and , respectively). This kind of thing
could go on for quite a while: Six rockers on one DIP switch gives you 64 different
configurations,so with 16DIPswitchesyou haveawhopping512voicing options.

Whywould I wanttoinstallthe Sound Wizardmoduleinthe INVADER II?
The INVADER II's fundamental sounds have already been tweaked to the lofty tonal
standard you would expect from a high-end ENGL amp. The was not
designed to improve the amp's sound quality, but rather to fine-tune the excellent
fundamental sound to suit your personal taste and sense of style. In other words, the

options assigned to the Sound function on the amp. These voicing options are
described in chapter 1 of the INVADER II manual. The configuration of the six rocker
switches on the currently selected DIP switch now determines how the amp's Sound
function works. When all rockers apart from rocker #1, , on the
currently selected DIP switch are set to OFF, there will not be any voicing option
assigned to the INVADER II's Sound function. This configuration is the same as when
the amp's Sound function is off and the is not enabled or installed. This
settingaffordsyou access to the fundamentalsound provided by the selectedchannel
and gain stage. Bear in mind there is one exception: Rocker #1's Gain Level Step

Ifyouwishtoaccesstheamp's fundamental sound even when the ison,
the configuration described above will let you do so: Set all rockers apart from rocker

amp's voicing will not change when the Sound function is switched off and on at the
ampifall rockers on amatched pair of DIP switches(Sound function disabled / Sound
Function enabled) addressing the same channel and gain stage (e.g.

wouldbe heard with the Sound function switched both off andon. The samegoes for
identical configurations of two complementary DIP switches addressing the same
channel and gain stage: You will not hear any difference in tone when the Sound
function'soperating status changes.Here'sanexample:

In this configuration, rockers #1 through #6 have the same settings for Channel 1 in
Low Gain mode. There would be no audible change in the amp's tone if you were to
switch the Sound function off and on because the assigned voicings are the same for
both operating statuses. In other words, identical configurations of complementary
DIP switches have no practical use apart from the fact that some such configurations
can be used to access the amp's fundamental sound even when the is
on.
Of course, the Sound Wizard module off / on switch (1) also restores the Sound

All this looks rather complicated on paper. In practice, though, you'll find that these
voicingsessions will come easy to you. The LEDsarrayed to the left of the DIP switches
and configured in identical colors as the LED channel indicators on the front panel are
abig visual aid, makingiteasytosee what you're voicing.Let'srunthroughan example
byfine-tuning Channel 1:
Let'ssayyouwant to configure a fat clean tonewithlotsof low-end thunk for Channel
1 in Low Gain mode and, as an alternative, a percussive, spanking clean sound with
plentyof top end.
First select Channel 1 by pressing the Channel Selector button (7/amp) on the front
panel of the amp. If necessary, press the High Gain button (19/amp) to switch to Low
Gain mode. Finally, if the Sound function is enabled, press the Sound button (1/amp)
to disable it. If the is disabled, activate it by engaging the slide switch
(1).Thegreen LED next to the DIPswitch(2)shouldilluminate,indicatingthatChannel
1is inLowGainmodeand theSoundfunctionisoff.
GotoDIPswitch(2)andswitchrocker#1, ,on by pressing down on the switch
to raise the end labeled 'OFF'. If you want an even thicker low end, you can also set
rocker#2, Low Midrange, to ON. Rocker switchsettings affect thevoicing in real time,
so you can immediately hear how each setting shapes your sound. Rockers #3, #4 and
#5onthisDIPswitchshouldremainOFF.Combiningtwovoicing options such
LowMidrange
and thatboost frequencies can also boost thevolumelevel, so you may
want to attenuate configuration like this. This is easily done by setting rocker #6,
Attenuator
On to our next step: Press the Sound button (1/amp) to activate the Sound function.
The red LED above the button lights up and the green LED next to the DIP switch (3)
also illuminates to indicate Channel 1 is in Low Gain mode and the Sound function is
enabled. Go to DIP switch (3) and set switch #5, , to ON. If you really want to
bringup the higher frequencies,you can also setrocker #4, ,to ON. Rockers #1,
#2and#3 on this DIP switchshouldremain OFF. Use rocker #6, ,ifyou wish
toadjust therelativevolumelevel.
Rocker switch #1 gives you a special option for Channel 1 and Channel 2 in High Gain
mode called . Without the , the amp's High Gain button
selects the two settings and . The Sound Wizard's Gain Level Step
option lets you access an additional gain stage between the two stages that is hotter

Here's another tip you might find useful: Sometimes it helps to compare the amp's
fundamental sound with a voicing of your own like the one we just configured in the
exampleabove.Todothis,simplysetalltherockersononeofthetwocomplementary
DIP switches – that is, the paired Sound function disabled / Sound function enabled –

you the fundamental sound. Then you can use the Sound function (1/amp) for A/B

Atip from thedesigner:
There are a few more things you should know about the Gain Level Step option: It is
beneficial in that it adds a third Sound Wizard-actuated gain stage to the two gain
stageshardwiredintotheamp.You can access this extra gain stage for Channels 3 and
4when High Gain ontheamphasbeen switched OFFsothattheLED above the button
is extinguished. This extra stage's gain level is just marginally higher than that of
Channel2 in High Gain mode, but it is voiced differently. You can configure up to four
different sounds for Channels 3 and 4 using this extra stage with the lower gain level.
Todo this, set rocker #1, , on DIP switches 10 and 11 for Channel 3 and
on DIP switches 14 and 15 for Channel 4 to OFF. If rocker #1 on one of these four DIP
switches is in the ON position, the preamp will switch to the gain level that can be
accessed directly on the amp via the preamp High Gain button – that is, when
Gain Sound Wizard
is switched off – when the is not enabled or installed. The
following rule applies to the other four DIP switches (12 and 13 for Channel 3 and 16
and17 for Channel 4when Channels 3 and4 are in High Gain mode): When rocker #1,

InstallingandOperatingtheENGLSoundWizardmodule
HEADS UP: Please be sure to read these instructions before installing
the Sound Wizard module in the amp.
Take note of the following information and heed these instructions when installing
theSound Wizard moduleintheENGL INVADER IIamp:
1.TheSound Wizard module is securelymounted in a specially designedrear panel for
the INVADER II amp. The type Z-16 Sound Wizard module comes preinstalled in this
specialrear panel.
2. The first thing to do before installing the module is to disconnect the INVADER II
amp from mains power, for example, by unplugging the mains cord from the Mains
socket(40/amp).
11
3. If the amp was in operation, allow it to cool down for at least 15 to 20 minutes
before removing the rear panel because otherwise the power tubes will still be hot
enoughto burn yourskin.
4.Placetheampon a stable surface such as aworkbenchbeforeinstalling the module.
You don't want to run the risk of damaging the device or hurting yourself if it falls off
anunstable platform.
5.Usea suitable Phillips head screwdriver to remove the seven screwssecuringtherear
panel. Be careful when removing the last screw. You don't want the back cover to fall
out,so youmaywanttohold itinplacewithyour freehand.
6. Carefully remove the rear panel. If it sticks, gently lift it with a flat-bladed
screwdriver.
Use scissors, a small wire cutter or other suitable tool to carefully cut the cable tie
holding the ribbon cable. Proceed with extreme caution so as not to damage the
ribboncable!
7. Place the rear panel holding the Sound Wizard module close enough to the amp so
you can plug the IDC connector at the end of the ribbon cable inside the amp into the

8. The IDC connector on the ribbon cable is bump-polarized on one side to prevent it
from being plugged the wrong way round into the box header on the Sound Wizard
module. A center notch on one side of the box header accepts the bump on the IDC
connector that prevents a reversed polarity connection. Please make sure you align
thebump and notchproperly.Donot useforcetoconnectthe two!
The two release levers on the sides of the box header both have to be at 45° angles to

Nonetheless, I do want to devote a few more words to an optional feature that
extends the tonal capabilities of the Sound function on the INVADER II amp. It caters
to demanding players who want to sculpt their sound with the surgical precision of a
scalpel rather than beat it into shape with a mallet. Closet hot-rodders and amp
modderswill find plentytolovein thistool.
Seeking to give creative guitarists practically unlimited freedom to shape their tone, I
started tinkering with the idea of a sound-tuning tool for everyone. Eventually, we
cameup with the SoundWizard module. This optionaladd-on enables any guitaristto
fine-tuneall the fundamental sounds of the INVADER II amp without having to take a
soldering iron to its circuitry. Best of all, these modifications can be done without any
knowledgeof electronics. Restoring theINVADERIItoitsoriginal voicing isassimpleas
flipping a single switch. The unique Sound Wizard module is truly extraordinary
becauseitdoeswhatsomanyguitaristshavebeen wanting to do for such a long time -

The Sound Wizard module sits in the amp's rear panel, so all you have to do is replace
thepanel. There'snoneedtoremove theamplifierchassis.
A single connector plugs the Sound Wizard module into the amp's circuitry. The ENGL
Sound Wizard module provides 96 rockers on 16 DIP switches for fine-tuning your
sound. 16 LEDs next to the DIP switches tell you which configuration of rockers is
currentlyactivefor a given amp mode(Channel, Gain & Sound settings). Aslide switch
enables and disables the Sound Wizard module. The module's status is indicated by a
separateLED on themodule as well as by the LED on the amp's front panel. You
can encode a total of 64 different settings on the Sound Wizard module for each amp
mode.The variations onChannel,Gain& Soundsettingsgiveyoua totalof16modes.

All this means you have a whole bunch of configurations for fine-tuning your amp. In
addition to offering specific voicings such as , and , the
