INTRODUCTION

24/7•C Compressor Limiter Plug-In delivers classic dynamics processing suitable for a
wide range of compression needs: from vocals and leads to drum loops and even com-
plete mixes. 24/7·C delivers a harmonious blend of warmth, color and energy.
24/7•C is meticulously modeled after a vintage leveling amplifier known for its colorful
tone.
24/7•C is perfectly suited for adding bite to drum and guitar tracks, adding presence to
vocals that sit up-front in a mix, adding energy to a track, or simply applying a rich,
warm texture to a single track or a complete mix.
For a detailed description of dynamics processing, please refer to the “The Compression
Process” and the “The Limiting Process” sections of the PowerCore CL manual PDF.

scrolling on both Windows XP and Mac OS X. Simply place the mouse over a parameter
value field and use the Scroll Wheel to increment/decrement the associated parameter-
value.

For each open instance of the 24/7•C on PowerCore devices (X8, FireWire, Compact,
Express, mkII, Unplugged), the following DSP usage applies:

RReelleeaassee
The release knob varies the release time of the compressor. The higher the value of this
parameter, the faster the release time.
RRaattiioo
The ratio buttons change the compression ratio to 1 of 4 default ratios: 4:1, 8:1, 12:1,
and 20:1. When no button is engaged, the compressor is not active, but the input and
output gain will effect the level of the sound.

Sidechaining in audio production refers to using the dynamic content of one track to
control the processing of an effect inserted on another track. Applications for
sidechaining are numerous. The TC SideChainer plug-in is included with the PowerCore
package and is used in conjunction with a number of plug-ins, one of these being the
24/7•C.
By using the TC SideChainer plug-in with 24/7•C when mixing, you are able to create
both “ducking compression” as well as de-ess processing.
Please refer to the SideChainer plug-in manual on the CD for additional information on usage
of the SideChainer plug-in.

For the 24/7•C to respond to an instance of the SideChainer plug-in press “ON” and
select the relevant SideChainer instance from the drop-down menu.

The Amount parameter determines how responsive the 24/7•C should be to the dynamic

WWAARRNNIINNGG: Do not be mislead by the attack and release knobs; unlike contemporary compressors,
turning the knob of this Plug-In clockwise results in faster attack and release times!

By changing the Input Drive, you will change how much the dynamic content of the input
signal will be compressed: the more you drive the Input, the more compression will be
applied to the signal.

Set the output gain to adjust the level after compressing the signal.
AAttttaacckk
The attack knob varies the attack time of the compressor. High settings result in fast
attack times, - lower settings result in slow attack times.

This option selects the placement of the meter in the signal path, either pre-processing
(Input) or post-processing (Output).

The Peak Hold option will vary the time that the maximum peak value is displayed in the
meter: the hold time range, in seconds, is 10, 6, 1, None or Forever – which is handy
when you are not watching too closely. There is also a Reset option, useful for those
times when Peak Hold Forever is engaged.

This option will change the behavior of how the Needle responds to audio. The higher
the value selected, the faster and more “tweaky” the needle will respond to the metered
signal. The lower the value, the slower and smoother the needle will respond to the
metered signal.
The lower the Needle Sensitivity setting, the more likely it is that transients will not be
indicated.
MMeetteerrSSccaallee
This option will set the metering scale of the VU meter. When selecting Peak as the
metering scale, you are metering the maximum amplitude of the signal. When “RMS
Average” is selected as the metering scale, you are metering the average amplitude of
the signal, which is approximately a difference of 3 dB on a logarithmic dB scale.
Selecting “RMS Average” may not reflect much signal activity at most settings due to the
overall scale of the meter. Generally, you will want to have “Peak” selected as the default
Meter Scale.
MMiixxCCoonnttrrooll--PPaarraalllleellCCoommpprreessssiioonn
Typically a compressor will process the entire signal fed to its input. However, with the
Mix control you can process the signal using what is commonly known as “Parallel
Compression”. Parallel compression allows mixing of the processed/compressed signal
with the dry/uncompressed signal. In many situations this will give you the “best of both
worlds”. - The punch from the dry signal and the peak control from compression.
CCoommbbiinnaattiioonn
24/7•C can have several ratio buttons engaged at the same time. When pressing multiple
ratio buttons, the ratios are added together. So, if you engage the 12 and 20 buttons,
your compression ratio will be set to 32: 1. To engage multiple ratio buttons, hold the
“Shift” key while engaging the buttons.
AAllll
24/7•C has the ability to engage all Ratio buttons at the same time. This popular trick
will result in a somewhat quirky behavior, that is certainly worth trying.
The VU Meter indicates either the Peak or RMS average of your signal, depending on the
Display Options selected. The numeric readout is always an absolute Peak value, plus the
calibration set by the Meter parameter.
Should your PowerCore cards be fully loaded and there is not enough free
processing on your DSPs, the display will come up in a disabled state. Should this
occur, it is advised to remove the Plug-In from the mix.

When the “OFF” button next to the VU meter is engaged, the Plug-In is completely
bypassed. Gain Reduction can be displayed when selecting the GR button. It is also

possible to calibrate the meter to view the level with an offset.
The calibration options are +4 and +8.
The calibration set in the Meter section will affect both the needle and the PPM readout.

We recommend using the dedicated PowerCore file handling system that, apart from
recall; store and compare facilities, allows for easy exchange of entire preset folders with
other users, between Windows/Mac platforms and also between different host
applications.
FFiillee
Click “File” to open the File menu.
Load Preset: Select to load presets from the default preset location.
Save Preset: Select to save the preset in My Presets folder.
My Presets: Via “My Presets” you are able to load you own presets.
If you chose to store presets in other locations than the “My Preset” folder, these
presets will not appear in the “My Preset” drop down menu. However, you can still
navigate to, and load these presets via the Load Preset function.
PPrreesseettnnaammee
This is the name of the preset.
UUpp//ddoowwnn
The [Up]/[Down] arrows can be used to browse through all presets.
AA//BB
With the A/B compare function you can easily compare different parameter settings when
working with the plug-in.
When you start working with your preset, the A/B button is grayed out. This state
indicates that the settings in both memory locations A and B are identical - so there is
actually nothing to compare.
PRESET HANDLING
As soon as you touch one of the parameters, the memory location “A” will be active. All
parameter changes will be applied to memory location “A”. If you switch to memory
location “B”, you go back to the starting point, and all further changes will now be
applied to memory location “B”.
Every time you press the A/B button, you will toggle between these two memory
locations.
The A/B memory locations are temporary settings only! Saving a preset, will save the currently
selected memory location only. The setting of the other (hidden) memory location will not be
saved!
RReesseett
Click “Reset” to clear memories A/B and return to the originally recalled preset.

The following locations will describe where you can find the presets, which are stored in
a folder unique to each plug-in:

• To delete a preset file, simply move it to the “Trash” or “Recycle bin”.
• To create a new sub-folder that appears in the plug-in menu, simply create a new
folder in the plug-in folder that resides in the PRESETS folder of the plug-ins default
preset location.
A folder will not appear in the Preset File menu unless it has at least one preset inside!
