Lead Gain
Gain control for the Lead Channel. This knob determines the preamp‘s input sensitivity when Lead Channel
is selected and, by extension, the preamp signal´s saturation level.
Contour Switch
The CONTOUR feature alters some parameters and the efficiency of the EQ system in CRUNCH II / LEAD and
mainly becommes audible in the lower mid range area between 300 and 700 Hz and to some degree in the
upper frequency range between 1.5 and 3 KHz. Activate CONTOUR for a pronounced mid range spectrum.
The Contour sound option can also be switched via MIDI program change, MIDI Controller #29, or the ENGL
Z9. The red LED above the button lights up to indicate when CONTOUR is activated.
A TIP FROM THE DESIGNER:
From the technical aspect the CONTOUR function influences the operation
mode of the EQ system, mainly the mid control range. If you desire to get a strong mid frequency notch (a
very heavy sound style) with a massive but defined bottom end and focused treble leave CONTOUR off. For
a pronounced mid frequency range and an assertive sound response activate CONTOUR.
Bass
This is the preamp voicing section´s passive low-frequency EQ for Crunch II and Lead.
Middle
This is the preamp voicing section´s passive midrange-frequency EQ for Crunch II and Lead.
Treble
This is the preamp voicing section´s passive hi-frequency EQ for Clean Crunch II and Lead.
Tone Balance
This additional EQ control knob is activated in Smooth mode only. Starting from the center position (12
o‘clock that is) of the TONE BALANCE control, a certain lower mid frequency range is emphasized if the
knob is turned counterclockwise. If turned clockwise an additional portion of treble is added to the sonic
scenario.
Rough / Smooth Switch
Switches between two completely unique overdrive characteristics in Crunch II and Lead:
ROUGH: pronounced bottom end and at the same time strong emphasis on the upper frequency range; high
efficiency of BASS, MIDDLE and TREBLE controls;
SMOOTH: strong emphasis on the mid frequency range; noticeably lower efficiency of BASS, MIDDLE and
TREBLE controls, TONE BALANCE control is activated;
The red LED above this button lights up to indicate the SMOOTH mode is activated.
The ROUGH/SMOOTH switching function can also be switched via MIDI program change,
MIDI Controller #15, or the ENGL Z9.
A TIP FROM THE DESIGNER:
The ROUGH sound mode is the right choice for heavier styles with fewer mi-
drange frequencies in the mix but plenty of low and high end frequencies. Choose the SMOOTH sound mode
