NONLIN2 STEREO EFFECTS REVERB
Congratulations with the purchase of your new Effects Reverb plug-in for PowerCore.
The NonLin2 Stereo Effects Reverb for PowerCore is another world class reverb direct-
ly ported from the System 6000. NonLin2 is an effect reverb, which differs from the
traditional natural sounding TC reverbs.
NonLin2 is capable of generating compact vocal ambience, percussive and dramatic
drum sounds, reverse reverbs and completely new “twisted” effects. Featuring an
amplitude envelope that is capable of rendering an untriggered gated reverb and a
‘twist’ parameter, which can radically alter the sound, this plug-in delivers a serious
advantage over other gated reverbs.
The NonLin2 plug-in runs on all available PowerCore at the common sample rates
from 32 kHz to 96 kHz.
The plug-in can be inserted in any VST or Audio Unit compatible host application as
Stereo-to-Stereo Effect or as Mono-To-Stereo Effect (depending on the host application
and the individual track settings).
The NonLin Stereo Effects Reverb algorithm occupies*:
Enjoy!

GLOBAL PLUG-IN CONTROLS
KEYBOARD COMMANDS
In most host applications, the NonLin2 Reverb supports keyboard commands for certain
functions. The following key commands are available for all plug-in parameters:
Key Commands in Mac OS X:
Fine Adjust = Apple key + mouse movement
Reset To Default = Alt key + mouse click
Key Commands in Windows:
Fine Adjust = Alt + mouse movement
Reset To Default = Shift + Control + mouse click
User Assignable Key Commands:
Depending on your host application, you have the ability to add your own keyboard
shortcuts to certain buttons. The supported buttons in NonLin2 are: Mem., A/B, the
previous/next preset buttons and the 2 page buttons: Main and Modify.
A right mouse click on the button will open a pop-up menu. Here you can select to
assign a new keyboard shortcut or to remove a previously assigned shortcut.
Note: The ability to use the assignable key commands highly depends on the host
application. Some applications do not pass key commands on to the plug-in.
SCROLL WHEEL SUPPORT
If you are using a host application that supports this feature, all of the NonLin2 knobs
and faders support scrolling on both Windows XP and Mac OS X. Simply roll your
mouse over a knob or slider and use the Scroll Wheel to increment / decrement the
associated parameter.
USER INTERFACE DISABLED
Should your PowerCore be fully loaded and there is not enough free processing on
your DSPs, the plug-in will come up in a “disabled” state. Should this occur, it is
advised to remove the plug-in from the mix.
Note: In case any PowerCore plug-in gets disabled either while loading a session or
during your work (e.g. you forgot to switch on PowerCore prior to loading a session),
you can always save your session without losing any of the plug-in settings. The last
setting of the plug-in will always be saved, even when it is in “disabled” state! This
also applies to saving presets.

FOCUS FIELDS
You can place your own set of parameters in the 6 focus fields at the bottom of the
plug-in. Making use of the focus fields can give you a better workflow, since you will
not have to switch pages all the time to find the parameters that you work with. You
can assign any parameter to the focus fields, and the focus fields are stored with the
session as well as when you save your presets.
To change the assignment:
• Press the Assign button. The Assign button as well as one of the Focus Fields
will be highlighted.
• Select the Focus Field you wish to link a parameter to, by clicking on that field.
• Click on the parameter you wish to link to the selected Focus Field.
• To get an unassigned (empty) Focus Field, click again on the selected parameter.
• Once you have finished the assignments, click again on the Assign button to
leave the assign mode.
OVERLOAD INDICATION (O/L)
The two LEDs in the metering section, between the input and output meters, will light
up in case internal DSP overloads are detected. You should lower the input level to
avoid these overloads. To reset the indication, click on the O/L LED.

THE PLUG-IN PARAMETERS
The plug-in parameters are spread amongst 2 User Interface pages – the Main page
and the Modify page:
MAIN PAGE
On the NonLin2 Main page, we have grouped the I/O and Envelope parameters of the
NonLin2. Also, on this page you can find the plug-ins preset handling. More about the
preset handling can be found in the section “Preset Handling” later in this manual.
LEVELS
Input Level
Range: Off to 0dB
Sets the Input Level for the algorithm. Reduce the input level in case you experience
overloads (O/L).
Output Level
Range: Off to 0dB
The overall Output level of the Reverb. Use this parameter to adjust the output level
to fit for following effects in your host application.

EENNGGLLIISSHH
8/ NonLin2
Dry Level
Range: Off to 0dB
Adjusts the dry signal level passed through the algorithm. For a typical send/return
configuration, leave dry level off.
Wet Level
Range: Off – 0dB
Adjusts the wet (reverb) output level.
ENVELOPE
The envelope determines the shape of the reverb. Due to the envelope control, you
can create the typical “gate reverb” effect without the use of any noise gate or similar.
The triggering is done automatically for you, just by feeding the plug-in with audio.
Pre Delay
Range: 0 – 500ms
Pre Delay offsets the Output and timing of the Envelope Generator. It is typically used
to obtain depth and definition in a mix, or align the effect with a musical beat. Delays
in the 10-40 ms range can be considered for percussive sounds, while dense vocal
slap effects could use 70-150 ms of Pre Delay.
Attack
Range: 0 – 500ms
Sets the Attack time (= build up) of the Reverb Envelope. The build up time is the
time the reverb tail needs to get to the maximum level.
Max. range for this parameter depends on the Hold and Release settings: The total
time for Attack, Hold and Release can not be higher than 500ms.
Hold
Range: 0 – 500ms
Sets the Hold time (= fully open time) of the Reverb Envelope. The “fully open” time
is the time the reverb tail maintains its maximum level. For a typical eighties style
response, Hold should be set at 60-120 ms.
Max. range for this parameter depends on the Attack and Release settings.

NonLin2 / 9
EENNGGLLIISSHH
Release
Range: 0 – 500ms
Sets the Hold time (= Decay) of the Reverb Envelope. This is the time the reverb tail
needs to disappear and is causeing the “gated” effect. For a typical eighties style
response, Release should be set at 0-100 ms. The most gated and unnatural effect is
obtained at short Release settings.
Max. range for this parameter depends on the Attack and Hold settings.
Envelope Display
ENVELOPE DISPLAY
The Envelope display is a graphical representation of the 4 envelope parameters and
the wet level. The 4 dotted lines represent the 4 envelope parameters and their posi-
tion in time. Take a vertical line at the handle and move it to the left to decrease the
time for that parameter or to the right to increase the parameter. Moving the horizon-
tal line of the envelope curve up and down changes the wet level of the reverb from
0dB (fully up) to off (fully down).
Note: The total time for Attack, Hold and Release can not exceed 500ms!

MODIFY PAGE
REVERB STYLE
Style
Selects the basic Reverb Style subjected to the Envelope and Twist modifications. The
Style parameter should be seen as an algorithm selection inside the algorith. Different
Styles have different features with regards to density, diffusion type, spectral
response, stereo image etc. Choose one that suits your program material.
Note: Differences are more pronounced with low Diffuse settings and Twist Ratios.
Diffuse
Range: 0 – 100%
Sets the amount of diffusion applied to the Reverb Style selected.
Note: For high Diffuse ratios, the Attack and Decay times of the reverb Envelope may
be slightly affected.
