1. Introduction
Congratulations on the purchase of your BRICKWALL HD True-Peak Limiter.
Over the past two decades, as the Loudness-Wars have raged, it has become clear
that the abuse of “loudness maximizers” in mastering can signicantly reduce
the audio quality for the listener.
When levels get squashed against the 0 dBFS digital ceiling, then reconstructed
intersample-peaks in Digital-to-Analog converters and audio le codecs (for
example MP3 and AAC), may be higher than the level that consumer equipment
was designed to handle. We call this level “0 dBFS+”, and often there have been
no limiters in music mastering preventing such peaks from happening.
The limiters in the BRICKWALL HD are designed to:
•• Continually measure if your signal contains 0 dBFS+ peaks
•• Then gently remove them
The BRICKWALL HD is a transparent and upsampling True-Peak Limiter that is
tightly based on the award-winning BW2 algorithm from TC’s System 6000. This
is an algorithm that for the last 2 decades has proven its worth on countless high-
prole records, feature-lms etc.
In the BRICKWALL HD, we have:
•• Rened the workow to include modern music streaming targets
•• Developed more options on Softclipping
•• And not least, added a new History view that gives in-depth information and
assists you in making the crucial master track decisions.
Two alternative types of Limiter are provided in one:
•• The conventional Master Limiter
•• The novel Loudness Limiter
The Master Limiter is a typical approach, with Input Gain to set the amount of
limiting, and Ceiling to set the amount of headroom in the exported le.
The Loudness Limiter is an all-new approach, enabling a workow suitable for
modern streaming services like Spotify, Tidal, and Apple Music. Here you set a
desired, resulting loudness level, which the BRICKWALL HD will automatically aim
for after listening to your track.
Both Limiter types include a exible and delicate SoftClipper that has three
available options from soft, smooth, to hard.
The BRICKWALL HD’s combination of True-Peak and Loudness numerical
information (STATS), provides the best possible support for making optimal
decisions of dynamics, head-room and loudness level in your precious mix or
master.
As a further aid, Loudness Range (LRA) and Peak-to-Loudness (PLR) read-outs
provide a tangible indication of how much dynamic compression and limiting you
are applying prior to, and with, the Limiter.
But remember, ultimately, your ears are the best tool you have.
For more information on Loudness, please visit:
https://www.tcelectronic.com/brand/tcelectronic/loudness
or visit:
https://nalizer.com/
For mastering in the DAW we recommend the MASTER X HD (3 band Expander,
Compressor, Limiter) plug-in in combination with BRICKWALL HD. There are
optimized preset “pairs” included in the plug-ins to get a head start.
For mastering in a separate and highly optimized environment we recommend
the Finalizer application https://nalizer.com/

2. Plug-in Installation
The combined BRICKWALL HD plug-in installer for both the NATIVE and DT
Desktop Controller products can be downloaded from the following page:
www.tcelectronic.com/brickwallhd-dt/support/
The BRICKWALL HD plug-in requires an active PACE iLok license to work. See
Chapter 3.
Using the Desktop Controller is optional, and all parameters are available in the
plug-in.
Save the installer le (.pkg or .msi le) in a convenient location on your hard
drive.
2.1 Installation on a PC
Double click the installer (.msi le). If you get a security warning, click ‘Run’.
Accept the license agreement and click ‘Next’.
Select which VST and/or AAX components you want to install. Pro Tools uses AAX
and most other DAW programs use VST. The installer will oer a default location
to save the le, but you can choose another location by clicking
the ‘Browse’ button.
Click ‘Next’ to begin the installation. When installation is complete, click ‘Finish’.
Note: If your DAW fails to detect the newly installed plugin, this can often be
xed by adding the following paths to the Plug-in Manager (or similar) of the
DAW. The default paths on a PC are "C:\Program Files\Common Files\VST2" and
"C:\Program Files\Common Files\VST3" for VST2 and VST3, respectively.
2.2 Installation on a Mac
Double click the installer (.pkg) le.
Proceed through the prompts to begin installation.
Click ‘Continue.'
A default location will be selected for installation, or you can select another
folder manually. If you have administrator authorization in place, you will need to
enter your password before beginning installation.
Click 'Close' when done.

4. Connection and Setup
4.1 Connecting the BRICKWALL HD-DT
Desktop Controller (optional)
Getting the Desktop Controller up and running couldn’t get any easier. Plug the
included USB cable into the unit’s rear micro-USB port, and connect the other end
to a free USB port on your computer. The Desktop Controller is bus powered, so no
other power cables are necessary, and no additional drivers need to be
manually installed.
The Desktop Controller will light up upon successful connection. You can now
apply the plug-in to a channel in your DAW to begin using the eect. This process
may vary slightly depending on your software, but generally should require
these steps:
• Select a channel or bus in your DAW to which you would like to add the eect.
Access the mixer page where you should see a section dedicated to eect slots
• Open the menu where you can select from a list of eect types, which
probably includes many stock plugins that are included with the DAW.
There should be submenu to view general VST/AU/AAX options.
• The plug-in will likely be found in a dedicated TC Electronic folder. Select the
BRICKWALL HD and it will now be added to the signal chain.
Double click on the eect slot that contains the BRICKWALL HD to view the
plug-in UI. There should be a green link icon at the bottom, and text that
indicates successful connection between the plug-in and the Desktop Controller.
4.2 Operating the BRICKWALL HD
After you have installed the plug-in, activated the iLok license, and optionally
connected the BRICKWALL HD-DT Desktop Controller via USB, you can begin
inserting the plug-in to your tracks.
Adjustments to the eect are done in two ways: either by using the plug-in user
interface, or optionally via the physical Desktop Controller.
BRICKWALL HD-DT
Laptop

7BRICKWALLHD User Manual
4.3 How to Insert the Plug-in
The BRICKWALL HD is intended for insertion directly into an eect slot on the
DAW master bus as the last plug-in, with the aim of handling the nal and very
delicate process before bouncing your audio project, or recording the output back
to a nal master channel. But it can also be used on a sub mix bus with great
success, or on a single instrument channel where limiting may be needed for
more artistic reasons.
4.4 Mono/Stereo Operation
The BRICKWALL HD is intended for stereo use, but can also be used both as a
mono instance on mono tracks.
In the case of a mono-out instance, the output signal is made by outputting the
left plug-in channel only.
4.5 Plug-in and Hardware Controls
After you have installed the plug-in, activated the iLok license, and optionally
connected the BRICKWALL HD DT desktop controller hardware unit via USB, you
can begin using it.
The controls of the plug-in and desktop controller are described in more detail
later in this manual.
Plug-in User Interface:
The Optional Desktop Controller Hardware Unit:
4.6 Connection Status to the Hardware Unit
The TC Icon family all use the same method to show the connection status
between the plug-in and the hardware unit.
Connection status is indicated on the lower left side of the plug-in window.
Successful connection is indicated with a green chain icon. The Tooltips area will
show the plug-in instance name that the hardware unit is currently connected
to. This is often the DAW channel name. If your DAW does not support this, you
may enter a name for the instance. This may be especially convenient when using
DAW project templates.
When using the NATIVE version only, this chain icon will remain grey:
If another instance of the plug-in already exists on another track, the chain icon
will appear yellow, and the text box will notify you where the plug-in is currently
active. Click the chain icon to connect the hardware unit to the new plug-in
location.
To summarize the connection status possibilities:
Most DAWs oer the ability to move or drag plug-ins from one track/bus to
another, and BRICKWALL HD supports this as well.
Most DAWs also feature an on/o switch for plug-ins, accessible inside the
plug-in window and/or the track itself. Muting the plug-in will make the eect
inaudible, but will not shut down the connection to the hardware unit.

6. Precision in Level and Time
In music track mastering, it is common practice to allow level to digital Full
Scale on a sample by sample basis. This has the consequence that down-stream
elements such as audio le codecs like MP3 and AAC or play back systems like CD
players will behave unpredictably, and in many cases add distortion you don’t
hear in the studio. The distortion is not harmonic, can be quite severe (more than
10 %) and cause early listening fatigue.
The key to remove this problem that we call 0 dBFS+ peaks, is to use a True-Peak
Limiter like BRICKWALL HD. The threshold can now be set safely at 0.0 dBFS,
while BRICKWALL HD still takes care of peaks that would otherwise cause
distortion.
The BRICKWALL HD limiter operates with highly-extended precision in both
level (True Innite headroom) and time (5 times oversampling). Its processing
engine, PPM level meters, History and Stats are all upsampled in order to identify
intersample and 0 dBFS+ peaks in the precious Mix or Master track. Therefore,
the meter scales are extended to +3 dBFS because excessive level normally
falls between 0 and +3 dBFS, and most consumer equipment already exhibits
distortion at +0.5 dBFS.
6.1 Two Limiter Approaches
The two alternative types of Limiter are provided in BRICKWALL HD: The
conventional Master Limiter, and the new Loudness Limiter.
Master Loudness
•• The Master Limiter is a typical approach with input gain to set the
amount of limiting, and Ceiling to set the amount of headroom in the
exported le.
•• The Loudness Limiter is an all-new approach, enabling a workow
suitable for modern streaming services like Spotify, Tidal, and Apple
Music. Here you set a desired, resulting, loudness level, which the
BRICKWALL HD, after listening to your track, will automatically aim for
by setting the Gain under the hood.
For both types, when the input level exceeds the Threshold, the signal will be
attenuated and the Gain Reduction meters at upper right of the main view and
the History curves will display the max amount of reduction applied to either of
the audio channels.

6.1.1 Master Limiter
Gain
Master
Lock
The overall Gain control sits at the input of the limiter. Adjust it to hit the True-
Peak and Loudness level that you aim for. When input peaks hit the Limiter
threshold at 0 dBFS, the limiter will kick-in to ensure that no peaks will exceed
0 dBFS True-Peak at the Limiter output.
Adjust the Ceiling to add margin relative to 0 dBFS.
The resulting Integrated Loudness that denes how loud the track is perceived is
shown as the blue Triangle in the right side of the main view. A set of descriptors
are collected in the STATS view. Press Reset to make a new measurement.
The small "lock" next to the control allows you to keep the value when a new
preset is selected.
Adjust the gain either by dragging over the control, or clicking on the number and
entering the numeric value.

4. When the Loudness measurement on the Limiter input (below the Set Gain
button) is not evolving anymore or when the button reads “Sample OK” you
may press the button to stop listening. During Listening, all measurements
including STATS and History in the plug-in view are based on the input
signal.
5. Now, the measured input loudness and the adjusted Target Loudness are
used to set the Gain behind the scenes, which will result in the Limiter
working to aim for the Target Loudness.
6. The Input Loudness Level may also be entered with your keyboard, by rst

•• It is recommended that you let the BRICKWALL HD listen to multiple
passages in your track, especially the loudest, to help BRICKWALL HD hit
the target optimally.
•• BRICKWALL HD will show dierent messages if the Set Gain-feature is
not able to nd appropriate settings due to the sample being: Too short,
too low audio level, no audio detected etc.

6.2 Adaptive Release Time
Many dierent objectives exist when it comes to peak-limiting audio. From
taking care of a few peaks in a gentle way, to signicantly pushing up the
average/peak ratio in order to raise the apparent loudness, for voice cut-through,
or a dozen other reasons. BRICKWALL HD extends the adaptive release time
control of earlier incarnations to include numerous new internal variables, to
make the algorithm respond intelligently for a number of applications.
Click the Adaptive LED to enable Adaptive Release Time and take advantage of
the dierent Proles.

6.2.1 Prole
The adaptive Proles allow you to tell BRICKWALL HD what your intentions are.
The selected Prole is only active when Adaptive is enabled.
Several internal variables are dynamically updated based on the Prole chosen,
so distortion is perceived (and measured) to be as low as possible for a given
loudness, and reduction in average/peak ratio. Maximum perceived distortion
tolerated is dierent from Prole to Prole. The multi-dimensional parameter-
space is fully continuous to avoid situations where distortion could occur.
•• The General Prole has a higher tolerance for perceived distortion than
Acoustic. It is still magnitudes better than analog designs, but may be
on the aggressive side for sensitive music. It is a good choice for many
types of music, and in live production where you don’t know what to
expect.
•• The Rock Prole again has a higher tolerance for perceived distortion,
and is therefore better suited for typical Rock/Electric mix and
mastering projects, rather than live applications.
•• The Acoustic Prole oers gentle processing with minimum static and
dynamic distortion. It’s a rst choice for audiophile limiting, for instance
with classical music, choir etc.
•• The Vocals Prole is targeted human voice, and adapts well to
asymmetrical signals. Used on composite material, perceivable
distortion is to be expected with large ratios of limiting.
6.3 Ceiling
The Ceiling is intended for reserving headroom in your master le against 0 dBFS
True Peak. Often, downstream processors like Digital-to-Analog converters in
consumer playback systems or lossy audio le Codecs like MP3 and AAC used in
Streaming Services are not safely handling peaks that cross 0 dBFS and this may
result in unpredictable distortion, even if the master le sounds perfect in the
studio. To ensure extra margin against this problem Ceiling can be left a bit lower
than 0 dBFS, say at -0.5 dBFS. Ceiling
6.4 Soft Clip
Soft Clip is a bandwidth-limited distortion eect, not unlike analog tape
saturation. Soft Clipping can assist the Limiter in increasing loudness for a signal
at the price of distortion. While the Limiter has a release time, the Soft Clipper
acts instantly to transients so their audible artefacts are dierent.
When the Limiter and Soft Clipper are used in combination, it is possible
to relieve the dynamic Limiter by applying the Soft Clipper. When used in
combination with the dynamic Limiter, Soft Clip can produce a louder and denser
impression than the dynamic limiter by itself.
Note: If misused, excessive Soft Clip may lead to an ear-fatiguing sound.

6.4.1 Soft Clip Threshold
The Soft Clipper sits on the plug-in input before the gain applied by the Limiter.
Therefore the Soft Clip threshold setting relates to the plug-in input level shown
on the Input PPM meter.
Adjust the Threshold by dragging the control or by clicking and entering the
value.
Note: The Threshold can be easily set by viewing the inner-ring level meter
inside the Threshold parameter outer-ring. A highlighted overlap between the
signal level and threshold rings will indicate that the Soft Clipper is in action and

6.4.2 Soft Clip Type
The BRICKWALL HD includes newly-rened and developed options for Soft
Clipping.
There are three Types to choose from, and they all represent variations on the
soft clipping theme. Which of them is preferred on the specic content with the
chosen threshold, and possibly in combination with the Limiter, can only judged
by listening in the given situation.
Soft Clip On
Soft
Smooth
Hard
Soft Clip
Type
•• Soft is a 9 dB “knee” soft clipper
•• Smooth is a continuous “knee” from very low levels all the way to the
top. The curve is optimized for least perceptual distortion.
•• Hard is a 2 dB “knee” soft clipper
Note: Use the Soft Clip On/O as a convenient way of A/B’ing the settings.
Note: To avoid nasty surprises, such as an unexpected high amount of clipping in
the last chorus – because it happened to be a little louder – make sure to check
the Soft Clip threshold setting at the loudest passages in your track.
Note: When processing sensitive material, and for live applications, it is
recommended to turn o Soft Clip to avoid bad surprises.
6.5 Operational Hints
Master Limiter: Normal operating procedures involve rst setting the Limiter
Gain in order to reach the desired Output level.
Master
Loudness Limiter: Set the output Loudness Level, activate Set Gain while playing
back your track and let the BRICKWALL HD automatically set the limiter threshold.
Click the Set Gain button again to stop measuring when it has measured long
enough – observe when the measured loudness value below the Set Gain button
has found its level.
Loudness
Use the Gain Reduction meters, the History readings, the STATS, and your
ears, as guidelines to when it is time to stop adding more Limiter Gain, or if
the Output Loudness level is maybe set too high. For not-previously limited or
-compressed signals, as a rule of thumb, be very careful if exceeding 8 dB of total
gain reduction, if not for artistic reasons. If the signal is already dynamic range
compressed, less drastic limiting treatment should be used.
We recommend ne-tuning the limiter parameters, in combination with
parameters of any dynamic compressor earlier in the processing chain.
Experiment with dierent Limiter Release times, or use the highly intelligent
Adaptive Limiter Proles relative to your music style, and, if needed in order to
relieve the Limiter a bit, add Soft Clip and nd the type and amount that best
compliments the material.
6.5.1 How to read the History
The all-new scrolling History view gives in-depth information and assists you
in making the crucial mix or master track decisions. While we fully support that
your ears is the most important tool, you may nd it useful in the delicate nal
adjustment process to see a scrolling view of the audio transients as well as the
gain reductions for both the Limiter and the Soft Clipper.
Loudness Output
History
Input
Limiter
Soft Clip
It is possible to see the following:
•• The release time of the limiter, and see how it may end up nearly as a
general level reduction of your mix if the Release Time is too long
•• How the dierent Limiter Proles behave on your mix, especially if you
cycle a small part of your mix while looking carefully at the Limiter Gain
Reduction curve
•• How the Soft Clipper is an instant gain reduction, compared to the
Limiter, which has a dynamic behavior. This can be seen both on the
Gain Reduction curves, as well as on the dierence between the Input
signal (grey curve) and the Output signal (white curve)
•• How the Ceiling parameter sets the margin from 0 dBFS to the max
True-Peaks of your mix
•• The relation between the transients and the short term (3 sec) Loudness
curve. The Loudness curve will display how your mix progresses
loudness-wise, for example from verse to chorus, or from rst to last
chorus. This will help you decide if it has the amount of impact you
are aiming for. In this process, it may also help suggesting changes in
the upstream-process such as the actual mix or potential master bus
compressor settings

decisions on your mix

6.6 Modern Mastering, Loudness and
True-Peaks
The BRICKWALL HD is highly suitable for the mastering process, with many ways
to make your mix sound better, but if not used wisely, there are many ways of
making it sound worse!
There is a risk of becoming speed-blind in the tuning process, and at rst prefer
an over-compressed and loud-sounding track. This is a situation that can be
avoided by:
•• Knowing your music genre deeply
•• Using relevant reference tracks for comparison
•• Ensuring calibrated monitoring levels
•• Using an optimized monitoring environment
The resulting Loudness and Dynamic Compression are two of the most important
properties of a track, adjusted nally in mastering. These two properties can be
regarded as counterparts to each other. In other words, it is important to:
•• Decide how loud your tracks should be
•• Design the dynamic prole of your music
Due to the xed 0 dBFS ceiling, louder tracks have less dynamics, and “weaker”
tracks will potentially have more dynamics.
We recommend that you do not hyper-compress and limit your tracks to the
extreme in the mastering process, in order to achieve a loud track. If you overdo
it, it will reduce the audio quality of your work. And often, there is even a penalty
in playback stages so your loud track may end up sounding weaker, rather than
louder.
6.6.1 Loudness
The Loudness approach to music mastering is based upon similar methods
introduced more than a decade ago by the industry producing audio for TV.
Loudness measures how loud we actually hear audio, which is dierent from
“level” PPM meters that look at transients only. The Loudness method includes
K-ltering that emulates human hearing, where bass aects the perceived
loudness level less, and where frequencies from approximately 2 kHz and up
aect the perceived loudness level more.
Loudness is a modern, but still well-rehearsed reference method, which is
standardized in BS-1770, and many music streaming services refer to this
standard, or similar proprietary methods.
Loudness is measured on the LUFS metering scale. LUFS stands for "Loudness
Units Full Scale." The scale does not measure sound as a dB meter or a VU meter
would. Rather, it accounts for how the human ear (and brain) perceives the
loudness of a track. That is also why there is only one loudness value or level,
instead of one per channel.
Loudness examples: Some Streaming Services will aim for -16 LUFS loudness
when they play back music tracks with “Sound Check” enabled. The AES
community recommend streaming music between -20 and -16 LUFS. Often
you will see songs that measure -14, -12, -10 or even -8 LUFS and it will vary for
example by music genre.
6.6.2 True Peak
Often, there can be small peaks of sound in-between digital samples, inter-
sample peaks, that go undetected in digital tools including our MASTER X HD.
Where traditional peak meters and conventional peak limiters fail to read those
true peaks of sound, a True Peak meter will provide the mastering engineer with
the actual reading.
Without a True Peak meter and True-Peak Limiter especially, a mastered track
could go into digital clipping when converted to a lossy format like MP3 or AAC
or when being Digital-to-Analog converted in normal playback systems. This can
happen, even if no distortion is heard when monitoring the nal master.
For a modern, versatile and trustworthy mastering chain, we recommend the
BRICKWALL HD True-Peak Limiter is inserted after the MASTER X HD to ensure
elimination of the potential and problematic inter-sample peaks in your nal
master track.
6.6.3 Beware of The Loudness Wars
An important note on loudness, is that there has been a trend in mastering
toward making songs appear louder and louder. Since you can never exceed
the 0dBFS digital ceiling, applying a brickwall Limiter at the nal stage, the
result often has been to apply very aggressive settings on dynamics tools such
as multiband compressors, so-called ‘loudness optimizers’, as well as the nal
Brickwall Limiter itself. This phenomenon has been referred to as ‘The Loudness
Wars’.
This escalated because we naturally perceive a louder version of a song to be
better than a softer version, when you compare them directly. Another cause is
that record industry people would compare an ‘airplay’ version of one track to a
newly mastered CD track, where the former tended to sound louder and fatter
due to FM broadcast processing – leading to a request to make the master louder,
with more cowbell. Well, the ‘wars’ may have peaked, but it is still something
that you should be aware of and pay attention to. And while we say that they
may have peaked, they are not completely over…
Further, if you apply extreme amounts of compression, distortion occurs, which
may lead to listening fatigue for you as well as your audience. Of course, the
amount of compression that you can use in order to t a certain music genre can
vary, but just stay aware of how it aects your music, and act accordingly.
It is also very important that you always listen to your own mastering project and
your reference library at the same loudness level when you compare them. There
is no doubt that while a heavily compressed song – dynamically speaking – may
sound more impactful at rst, you will sacrice detail and nuance.
Finally and as mentioned above, keep in mind that the current trend in music
streaming is a target loudness of approximately -16 LUFS, so if you deliver a
signicantly louder song, it will get turned down automatically if the listener
chooses to apply the ‘normalization’ feature such as ‘SoundCheck’ or ‘Same Level’
that aligns the loudness of the songs in the library. And if that happens, your very
loud song may well end up sounding much less impressive than the competition!

6.6.4 Compress-O-Meter - Master Analyser
TC Electronic has launched a free on-line service at the following address:
https://nalizer.com/analyzer
This analyzer can help you investigate and decide the suitable loudness level
and amount of dynamics processing for your music, when you compare it to your
preferred reference tracks, or pre-analyzed giant hits through the history.
A central part of this service is the Compress-O-Meter:
The X-axis is the amount of Dynamic Compression. It is unit-less, so you should
not add “dB”, “ratio”, or similar, when thinking about it.
The Dynamic Compression is based on the track’s Peak-to-Loudness (PLR) value
and a measurement of the micro-dynamics of the track.
•• Very dynamic music with lots of transients and loud and soft passages,
will have a low Dynamic Compression value, to the left in the Compress-
O-Meter.
•• Very dense music with little transients, will have a high Dynamic
Compression value and show up to the right.
The Y-axis is the full track Loudness value, shown in LUFS (Loudness Units Full
Scale).
6.6.5 Modern Mastering
Another highly relevant combination of processing can be carried out with
MASTER X HD and the TC Electronic BRICKWALL HD limiter in series as the last
step before bouncing your mix or master.
The MASTER X HD will add 3-Band Expansion, Compression and Limiting, and
it is able to act both as downward and upward compressor, so it is a strong
companion to the BRICKWALL HD.
There are suitable presets “pairs” located in the Preset menus of the two plug-ins
as an aid to using the two plug-ins together.

7. 2 Set Gain procedure using the optional
Desktop Controller
With Loudness Limiter selected, holding Loudness Limiter (labeled Loudn) will
start the Set Gain procedure. This will automatically set the Limiter Gain behind
the scenes, based on the audio content and your Loudness Target.
1. Make sure you have set the Target Loudness level, say -15 LUFS. The Spotify/
Apple/AES Stream texts will individually light up if your Loudness target
is appropriate for these platforms. Note that these recommendations are
bound to change now and then. To see the latest evolvement, please refer to
https://nalizer.com/analyzer
2. Start DAW playback of your project or track, and hold Loudness Limiter to let
BRICKWALL HD listen to the content. The Loudness Limiter button will blink
while the text display reads LIST. (Listening) and shows the accumulated
Loudness value while sampling the content. The Loudness bar in the display
will also show the accumulated Loudness value. The LED bar increases 1 LED
per second during Listening.
3. When the Loudness measurement in the display is not evolving anymore, or
when the plug-in reads “Sample OK” (when this happens the LED bar on the
Desktop Controller will not blink anymore), you may press Loudness Limiter
to stop listening. The display will ash “DONE”.
4. Now, the measured input loudness and the adjusted Target Loudness are
used to set the Gain behind the scenes, which will result in the Limiter
working to aim for the Target Loudness.
Please note:
•• We recommend that you let the BRICKWALL HD listen to multiple
passages, especially the loudest in your track, to help the BRICKWALL
HD "hit the target" optimally
•• The BRICKWALL HD Desktop Controller will show dierent messages if
the Set Gain-feature is not able to nd appropriate settings due to the
sample being too short, too low audio level, no audio detected etc.

8. Presets
The BRICKWALL HD oers a collection of factory presets, as well as the option to
create and save your own custom settings as user presets and favourites.
Note that most DAWs have a built-in preset function that appears on every plug-
in, which is often found at the top of the plug-in window.
It is not recommended to use this as your primary method of saving presets, as it
has limited functionality and does not allow the saved presets to be transferred
easily to other DAWs. Instead, we suggest using the Preset section at the bottom
right corner of the user interface window:
A single click on this PRESET window will bring up a menu with several preset-
related options. You can recall a factory or user preset from the libraries, save the
current preset, or create a new user preset with the 'Save as' option.
The presets menu is divided into Factory Presets and User Presets.
User Presets
Factory Presets
Factory Logo

Favourites Up/Down
8.1 Factory Presets
Factory presets are built into the plug-in and cannot be overwritten.
The factory presets have three main options:
•• Master presets: for when the BRICKWALL is used as with the Master
Limiter approach
•• Loudness presets: for when the BRICKWALL HD is used with the
Loudness Limiter approach
•• MASTER X HD Pairs: for when the BRICKWALL HD is used in conjunction
with the MASTER X HD Plug-in. The MASTER X HD has similar presets
When recalling a Factory preset or saved User preset, the name will appear in
plain text as shown below.
8.2 User Presets
If you make an alteration to any of the parameters in the current preset, the
preset name changes to italics as a reminder that something has changed from
the original factory preset.
To save this new setting as a User preset, click in the PRESET window, then select
the Save As option. Save it with an appropriate name. User presets can be edited
and organized as you like.

19 BRICKWALLHD User Manual
To discard the changes without saving, simply navigate away from that preset.
The altered preset will be saved as a user preset, with your new name for it, and
its name will appear in the User Presets window.
If you modify a saved user preset, you have the option to "Save" (rewriting over
the existing user preset) or "Save As" (save as a new user preset).
If you modify a factory preset, then only "Save As" is available (to save as a new
user preset). Factory presets cannot be overwritten.
User presets are not given a number unless you rst assign them as favourites.
(See Favourite Presets below.)
8.3 Favorite Presets
Creating your own presets will make them accessible from the Preset menu,
but they will only appear in the list of 100 presets in the plug-in or hardware unit
if you set them as a favorite. This is done by assigning a favorite slot number to
the preset using the Favorite menu.
Click the FAVORITE (heart-shaped) button in the preset window, then select one
of the 10 banks. Assign one of your custom presets to a favorite slot, then save
the preset. When a preset is set as a favorite, the "heart" logo will be lled.
When a preset is assigned a favorite slot number:
•• The preset is part of the 100 presets that can be recalled on the
hardware unit
•• The favorite number will be displayed on the hardware unit when
recalled
•• The favorite number will be locked so that two presets cannot be
assigned to the same favorite slot number. This is shown in the Favorite
menu by graying out the number in question.
•• The favorite number will be displayed in brackets when you browse the
presets menu
You can remove the favorite assignment by selecting the “Remove Assignment”
feature in the Favorite menu, then saving the preset.
8.4 Browse Favorites Only
The 'Browse Favorites Only' option in the preset menu allows the UP/DOWN
arrows in the bottom bar of the plug-in, or via the hardware unit, to scroll only
through the favorites list. Otherwise, scrolling goes through all presets.
8.5 Make Current Preset Default
Selecting 'Make current preset default' will cause this preset to appear every time
a new instance of the plug-in is created.
8.6 Reveal User Preset Folder in Explorer
To change the name of a preset, select 'Reveal User Preset Folder in Explorer'
and modify the le name. This will open a Finder (Mac) or Explorer (PC) window
where the user presets are stored. You can rename as well as delete, copy and
paste presets. This allows you to share presets with other users online, simply
pasting the new ones in this folder.

9. Software Updates
New versions of the software may be released to add new features and improve
performance. Updates can be detected from the plug-in directly and can be
installed after download from the website. See Chapter 2 for plug-in installation.
If the ’Automatically check for updates’option is checked inside the update
menu, the red dot will appear on the settings icon when a new plug-in
is available.
Click the gear icon and select “Check for Updates” to perform a scan.
9.1 Hardware Unit Software Updates (optional)
The hardware unit rmware will be included in each plug-in update.
After you have installed a new plug-in, the system will detect mismatched
rmware and indicate a need for update via a small red dot on the gear icon.
Click the “Upgrade to x.x.xx”eld to start the update. Progress will be indicated
in the plug-in, and the Feedback LED on the hardware unit will ash. (This
