A tip from the designer:
This knob setting determines to which extent the level drops when the active
mutes the signal; in other words, it sets the residual volume level. The further you
twist the knob clockwise, the greater the drop in (noise) level when the
mutes the signal.
Use this knob to set a threshold value (that is, the noise level) at which the
activates to suppress the signal. The further you twist the knob to the right, the higher
the signal level at which the kicks in. The can be activated and
deactivated as required for the Crunch channel and the two Lead channels by pushing
the front panel button (33).
, and generate different levels of noise, and I tuned the
ENGL 570 preamp's accordingly. However, there is some minor matching
variance between the three. (Lead channel and activated) stands
to benefit most from the , so I suggest that you tweak its two knobs for this
mode.
This stereo ¼" jack serves as the output of the frequency-corrected line filter. It delivers
an unbalanced stereo-signal and it is equipped with a ground terminal. You can patch
the preamp signal routed through this jack to a recorder or a PC's audio card via some
type of adapter (depending on the type of inputs on the audio card). Dial in the
desired signal level via the Level knob (43).
This LED lights up to tell you the Line Out is saturated. If it illuminates, simply roll back
the signal level using the Level knob (43).
This knob determines the level of the frequency-comensated Line outputs (41 & 44,
45). Use it to adjust the preamp's line output signal level to match the input gain of the
mixing desk or recorder's input.
The following factors determine Line Out level: the preamp input level (Gain), the
given channels' Volume knobs, and to some extent, the tone controls and sound-
shaping buttons' settings as well as the position of the Master knob. Those are a lot of
variables, so I recommend you proceed as follows: Configure buttons as desired and
dial in the desired settings on the front panel. Adjust the levels of connected FX devices
and signal processors. Finally, use the Level control to adjust the line level. The Line Out
is not overloaded until the Overload LED (42) lights up continuously. You can push the
level up to this point to match a mixer desk or recorder's input level requirements. Use
the given device's input sensitivity or gain control to fine-tune the line level.
