Engl INVADER II Operator's Manual page 8

All this means you have a whole bunch of configurations for fine-tuning your amp. In
addition to offering specific voicings such as Bright Twang , and Mid Boost , the Sound
Wizard also lets you modify the gain stages in certain modes and activate a special
parameter called Attenuator for each amp setting to balance out different volume
levels. You will find a detailed description of the Sound Wizard's tuning capabilities in
the manual that comes with the module.
2 Gain 1
Gain control for Channel 1's preamp section. This knob determines the preamp's input
sensitivity when Channel 1 is selected and, by extension, the preamp signal's saturation
level.
A tip from the designer:
The amount of distortion depends on your guitar's pickups and the High Gain ( 19 )
setting. In Channel 1, single-coil pickups may begin saturating the preamp when the
knob is set to about the two o'clock position; pickups with very high output levels
(humbuckers or active pickups) will evoke mild overdrive at even lower settings. If you
want squeaky clean tone, simply back off the Gain knob accordingly.
If your guitar sports single-coils and you want to add some grit to your tone and bite to
your riffs, set the knob somewhere between 12 and 3 o'clock. For higher output pick-
ups such as humbucking or active jobs, dial in settings between 10 and 1 o'clock and
activate High Gain .
3 Bass
This is the preamp voicing section's passive low-frequency EQ for Channel 1 .
4 Middle
This is the preamp voicing section's passive midrange frequency EQ for Channel 1 .
5 Treble
This is the preamp voicing section's passive high-frequency EQ for Channel 1 .
A tip from the designer:
To help you get acquainted with the amp's fundamental sounds, I recommend that
you set all tone controls to or slightly higher than the center or 12 o'clock position. For
higher-gain preamp sounds, your best bet is to turn the Treble knob down to prevent
the pickups and speakers from generating feedback (a setting in the 10-to-2 o'clock
range is recommended). You will find that grittier tones generally sound better with a
touch less treble because preamp saturation makes higher frequencies figure more
prominently in the signal. Each channel is equipped with a dedicated EQ so you can
tweak its sound separately to suit your taste and the given sonic scenario. Bear in mind
that you also have the Sound (1) button, as well as the power amp Presence (14) and
Depth Punch (15) knobs, at your disposal for shaping the frequency range. You can
program various MIDI presets with the Sound option remotely and have plenty of
tonal variations at your fingertips.
