6 Volume 1
Volume control for Channel 1's preamp section. Use this knob to adjust the volume of
Channel 1's preamp and dial in the desired balance with the other three channels' levels.
Because this knob is located pre effects loop, it also determines the send levels for both
FX loops when Channel 1 is selected. The green LED to the right of the knob lights up to
indicate Channel 1 is on. Use the knob (56) on the amp's rear panel to balance out the
relative volumes of High Gain and Low Gain modes.
7 CH 1
Push this button to activate preamp Channel 1 at the amp. The green LED to the right of
the Channel 1 Volume knob (6) lights up to indicate Channel 1 is active. Channel 1 may
also be activated via MIDI program change, the ENGL Custom Z-9 Footswitch, or a dual
footswitch.
8 Gain 3
Gain control for Channel 3's preamp section. This knob determines the preamp's input
sensitivity when Channel 3 is selected and, by extension, the preamp signal's saturation
level.
A tip from the designer:
Like Channel 4, Channel 3's gain structures range from vigorous to extreme, making it
a great choice of channel for fat, creamy lead sound with plenty of sustain. The High
Gain (19) and Sound (1) functions let you tune Channel 3's fundamental tone to suit
different playing techniques. This channel has plenty of headroom, so I recommend
setting the Gain knob to somewhere between 8 and 1 o'clock. This will let you dial in
impressive sounds with preamp saturation figuring prominently in the tone. The High
Gain function comes in especially handy in conjunction with Gain settings below 12
o'clock because you can use it to shape and access two distinctly different tones.
Extremely high gain and volume levels in Channel 3 can produce powerful
CAUTION:
feedback. Avoid feedback squeals; they can lead to hearing loss and damage
speakers! At higher volumes, back off the Gain, Treble and Presence levels in order to
prevent unchecked feedback!
9 Bass
This is the preamp voicing section's passive low-frequency EQ for Channel 3 .
10 Middle
This is the preamp voicing section's passive midrange frequency EQ for Channel 3 .
11 Treble
This is the preamp voicing section's passive high-frequency EQ for Channel 3 .
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 the center or 12 o'clock position. For higher-gain sounds in
Channel 3 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).
