Installation & Setup
When preparing for installation of your MAAT product, we recom-
mend that you quit all applications prior to proceeding. Also, aer
downloading the installer and prior to installation, let any anti–malware
measures you may have running scan the installer. en, temporarily
disable all anti–malware measures once scanning is complete.
To install, simply double click on the downloaded Installer for your
particular operating system. e installation process will guide you
through the install procedure. If you have an older OS version, restart-
ing your host may be required. Don’t forget to reënable anti–malware
measures or simply restart your host.
Licensing
MAAT soware is licensed through our dongle–free, cloud–based
license control framework. Cloud–based implies a connection to the
public Internet, which you will need for at least one computer under
your control. at net–connected computer does not have to be the host
machine on which you want to run MAAT soware. It can be any com-
puter to which you have access; see Oine Activation below.
Basically, you can activate a license on any machine and that activation
“sticks” or stays active for 30 days. You can have two simultaneous acti-
vations on two dierent machines. If you want to move the license from
one machine to another, you must “retire” or deactivate one of your two
activations.
Online Activation
ere are two ways to activate a license; either by opening the product
directly, or by using License Central which is our global licensing utility
installed with every MAAT product. If the product is a plug–in, you can
open an instance to start the activation process. If the product is stand-
alone or “native,” then you can simply launch the product. With License
Central, you can manage all your licenses within one unied interface.
In–Product Activation
To license your MAAT purchase directly within the product, instan-
tiate an example in your preferred plug–in host. When licensing, we
recommend you open a new session in your DAW just for this pur-
pose.

Figure 1: The initial Activation dialog
Instantiate the plug–in or, if an app, launch the product. Wait for
the user interface to open, then click on the Preferences’ gear icon.
Click on the Activate License button. Once the Activation dialog
appears, paste or type in your Product Key supplied at the time of
purchase. en click on Activate Online and follow the prompts.
Once your product is licensed on a particular host, clicking on the
Deactivate Online button will deactivate your license on that ma-
chine. Repeat elsewhere to reactivate.

License Central Activation
To activate any of your MAAT products or several at once, use Li-
cense Central…see below.
Offline Activation
If, for security reasons you have:
• an oine host computer not connected to the Internet
• or you plan on working without a reliable Internet connection
…it is best to go with an oine license.
is will license your MAAT product without the need to periodically
contact our licensing server. If you anticipate working without the in-
ternet for more than several months at a time or, for security purposes,
your studio machine is “air gapped” and has no Internet, take a moment
to surrender your online license, and replace it with an oine version.

To prepare for oine activation, you will need:
1. Your Product Key!
2. Some method to move your License Conrmation le to the of-
ine host machine.
You will need your Product Key that was supplied to you via e–mail
when you purchased your MAAT product. That second requirement
can be accomplished in any number of ways, but a USB ash drive is
oen readily available and most convenient.
e oine activation process starts with generating a License Request,
with a “.maatr” le extension, which is submitted on–line to our server
or via e–mail to MAAT Support <suppor[email protected]esk.com>.
A License Conrmation le, with a “.maatc” extension, will be returned
to you, which will activate your product.
To proceed, click on the Activate/Deactivate Oine button, and follow
the prompts. In a year’s time, 365 days from the date the maatr le was
created, a full oine license must be renewed using the same maatr/

License Central, located in MAAT’s Shared directory, is a free utility
that validates, repairs and logs your MAAT licenses. It also displays
what MAAT products you have installed and assists in downloading
both updates and demos. License Central is installed alongside all
MAAT products.
License Central lists all of our products, and shows you:
• If a product is installed and what licenses you have [CLOUD,
SUBSCRIPTION, TRIAL, OFFLINE]
• What versions are installed, and which version installers are avail-
able for download
It also provides:
• A one–click download of an update or a demo
• A button to activate or deactivate any of your licenses

Page 8 of 23 Page 9 of 23
• A copyable list of all your Product Keys
• One–click generation of the MAAT diagnostic report
In Use
When you launch License Central, it scans your host computer and then
attempts to match up each product found with a Product Key on our
license server. at scanning happens in real time, and the process is
shown as a progress bar. When quitting, this process happens in reverse.
Once all the licenses are validated, a list on the le displays all MAAT
products, including License Central. Products that are not installed are
grayed out, and installed products are displayed in high contrast. To
the right of each product entry is a check mark, which indicates that the
product is licensed.
Selecting a product entry displays information about the installed ver-
sion and if an update is available for download.
Controls
ere are two persistent buttons along the top. At upper le is Check
for Updates, which refreshes the list of installed products, and pings our
server again for currently available versions to download. It also recre-
ates your Product Key list.
At upper right, the Activate/Deactivate button brings up the familiar
blue and orange MAAT license window, allowing you to deactivate or
return your license to the Cloud. If you have requested a 365 day Oine
license, use the Create License Request function in the MAAT license
window, and have received your “.maatc” conrmation le, you can
take your license oine. Finally, you can also paste in a Product Key to
activate a new license.
Note: 365 day Oine licenses require a license conrmation le
as supplied by MAAT’s support department.
If any product is out of date, a third Download Update button will ap-
pear when that product is selected. is button is an express method for
updating your MAAT products.
At bottom le of the License Central window is an Auto–Refresh check
box, which is selected by default. Deselecting that will prevent License
Central from frequently scanning your host for changes including new
installs. It starts a scan every 3 seconds, waiting for completion of that
scan, then begins a new 3 second countdown before starting the next
scan. If you nd that License Central is interrupting you workow while
scanning, then disable Auto–Refresh.
Preferences
In License Central, the Preferences’ gear icon brings up the Preferences
window with four tabs.
Paths
For those who set up alternate directories for the management
of their plug–ins in a DAW, two alternate plug–in paths can be de-
ned. ese directories will be also included when License Central
searches.

Introduction
RSPhaseShier, a high delity frequency–dependent phase shier or
“phase rotator,” is great for any situation where you need to creative-
ly control tonal and harmonic content through phase manipulation.
RSPhaseShier was created in conjunction with Roger Schult/German
Audio Lab, and is a painstaking, 64 bit digital realization of the Phase
Shier W2324 hardware. From both the original W2324 Operating
Manual, and all of us at MAAT…“Dear customer, we sincerely thank
you for purchasing our product.”
“In order to maintain the factory specs and guarantee safe operation in
the future, we advise that you read the included operating manual…(it
contains) important notes for operating and handling your product.”
RSPhaseShifter Mastering Filter/Phase Shifter
Based on Roger Schult’s active analog W2324 Phase Shier module for
the API® 500 System, MAAT’s RSPhaseShier is a “…high precision tool
to solve phase problems in sound recording and playback applications.
Comb ltering is a common and usually undesirable eect caused by
dierences in phase when combining multiple signals from one source,
such as a microphone and a DI signal from an electric guitar or multi-
ple microphones on a kick drum. e phase shier is the ultimate tool
to hone in and correct those phase problems with unheard-of accuracy
and sound quality. Alternatively, experienced engineers will appreciate

Page 10 of 23 Page 11 of 23
the creative sound design possibilities oered by the module.”
“Furthermore, the (RSPhaseShier) can be used in the subwoofer path
of any playback system to optimize the low-frequency response and
remedy room mode issues thanks to the continuously adjustable phase
angle.”
“Within the selectable frequency range…any frequency build–ups or
cancellations due to the time delay between two sources or (when used
in the playback path) due to problematic room acoustics can be ad-
dressed by shiing of the phase. Simply select the desired frequency
with the thirteen position rotary switch and correct the level and phase.
A three position ip switch further allows phase angle extension in
excess of 180° as well as providing a bypass position for a quick and easy
comparison with the uncorrected signal.”
The Difference Between Hardware & Software
As with all Roger Schult by MAAT products, the RSPhaseShier is
hand craed and precision engineered in California by way of Germa-
ny. is is an explicit digital recreation of the analog W2324 topology,
not a modeling algorithm. We copied the functionality of the original
hardware without analog’s shortcomings. is tool’s value is more about
what it does technically, so we le out stu like fake transformer color,
hum, Johnson Noise or other distortion. ere are lots of colorful plug–
ins, we simply provide convenient access to the useful functionality
along with a stylin’ API 500 look.
Our algorithm provides top audio quality from 180°, at the upper limit,
down to a few degrees. We set the plug–in’s lower limit to 15°. A real 0°
is impossible, as it is in hardware. Also, values very close to 0° cause nu-
merical problems during calculation, as well as problems in hardware.
“It’s simply a mathematical fact of life,” as our designer says! Fortunate-
ly, in real workows, there’s no need for very small phase shis.
Because of high resolution calculations, we are able to extend the ranges
for frequency and phase shi compared to the original hardware. We
can do this while still maintaining full 24 bit audio quality in terms of
THD+N (Total Harmonic Distortion + Noise).
e hardware’s analog degree scale is highly non–linear, due to issues
with analog circuitry. e original W2324 has ten tick marks, from 10 to
125°. Freed from the limitations of an analog implementation, we have
moved to a true, linear scale and extended the range slightly, something
only possible in the digital domain. RSPhaseShier’s eleven tick marks,
in 15° steps, are:
15; 30; 45; 60; 75; 90; 105; 120; 135; 150; 165°
ough not technically a tick mark, the vertical line at 6 o’clock on the
dial, in addition to visually linking the phase adjustment control and
phase range switch, corresponds to the 180° end stop for the phase ad-
justment control.
Output Polarity
Also note that RSPhaseShier has an inverting output, as does the
original analog W2324 Phase Shier. In other words, the output exhibits
an absolute polarity inversion relative to its input. e phase shi values
starting at 15° above are actually negative values (negative polarity) but,
throughout the majority of this user manual, the minus sign has been
removed both for clarity and in keeping with the original hardware’s
markings. e inverted output does not aect the plug–in during use. If
desired, you can use MAATgo to re–invert the signal back to the origi-
nal orientation.
Functions
• Continuously adjustable lter gain range of ±5 dB
• Continuously adjustable phase angle between 15° and 180°
• 3 position range switch to bypass or extend phase angle from
+180° to 0 (360)°
• 13 position steeped or continuous rotary control to select frequency
range from 16 to 4 kHz
Applications
• Correct the phase between multiple microphone signals to
avoid comb ltering, such as when tracking drums or guitars
• Get control of phase problems when mixing a “DI” or direct
injected signal with a microphone signal
• Match and optimize the time delay or phase response of a
subwoofer in a 2.1, 5.1 or N.N monitoring environment
• Reduce the influence of standing waves (room modes) of
a loudspeaker setup in conjunction with one or more sub-
woofers
• Create ultra–wide sounds and phase sweeps by deliberate
phase manipulation of one side of a stereo track

The Interface
Once installed, the plug–in appears in your DAW as MAAT RSPhase-
Shier.
Figure 2: The RSPhaseShifter user interface
e straightforward RSPhaseShier user interface contains two rotary
controls, stepped gain and continuous phase rotation, a three position
range/bypass switch, a rotary frequency selector and three optional
mode switches.
Double clicking on a control resets the control to the default.
LEVEL
e top of the module is occupied by a rotary gain control with a range
of ±5 dB. is level control allows adjusting the output level to compen-
sate for potential level jumps caused by shiing phase.
PHASE
e phase control provides a continuous phase shi of 15° to 180°, with
the phase switch in the bottom position. Extending the phase range by
setting the Phase Mode switch, see below, to the top position (+180°)
increases the phase shi by an additional 180°, resulting in a total range
of 195° to 360°. Phase values between 0° and 15° are unavailable because
of limitations of the lter topology employed within RSPhaseShier.
Phase Mode
is three position switch is used to select the range of the phase shier.
Top position: +180° (+180 - 0°)
Center position: Bypass
Bottom position: 0 - 180° (0 - -180°)
e center position, the “0” setting or Bypass mode, provides a means
to compare the eect of the selected phase shi with the unprocessed,
original phase of the source material.
FREQUENCY
e phase shi is dependent on the selected frequency setting. Frequen-
cy selection is managed by an 13 step ELMA–style control with the
following frequencies conforming to ⅔ octave ISO recommendations:
16 Hz 400 Hz
25 Hz 630 Hz
40 Hz 1000 Hz
63 Hz 1600 Hz
100 Hz 2500 Hz
160 Hz 4 kHz
250 Hz
e Frequency control is stepped by default, and changes to a continu-
ous control when the shi key is held down.
DELTA
e DELTA switch, marked δ, lets you hear an isolated stream of only
the processed audio. is mode helps to aurally identify the aspects of
the signal that are being changed or processed.
Note that DELTA is unavailable within a MONO instance of RSPhase-
Shier. Also, don’t forget to disable DELTA mode when you’re done
nding your preferred settings.
Figure 3: RSPhaseShifter with DELTA enabled
Making Sense of DELTA

Page 14 of 23 Page 15 of 23
e use of the Delta function is an optional feature which makes sense
for specic advanced use cases. Rather than using it for pure phase
alignment against a separate track, it is particular helpful when you use
RSPhaseShier as an insert FX for modifying stereo spread in an MS
workow. To do so, rst insert an MS encoder prior to the RSPhase-
Shier, then the RSPhaseShier and subsequently an MS decoder. Now
you can either alter the phase of the M or Mid/Mono signal (le chan-
nel), the S or Side/Dierence signal (right channel) or both. Delta allows
you to hear the processed portion in this scenario, helping you to arrive
at the best setting faster.
DELTA Nonsense
When you use RSPhaseShier for the sole purpose of phase alignment
with another track, one not being processed by RSPhaseShier, using
Delta mode is not applicable because the mix or sum of your processed
track with the unprocessed track is what counts. Particularly when you
move the phase of a stereo room ambience track in relation to another
room ambience track, the use of Delta makes no sense!
Mono vs Stereo Operation
A mono instance appears as a double wide UI, with controls on the le
channel, and the right channel having a matching “cover plate” or blank
panel.
A stereo instance also appears as a double wide UI, with controls on
the right channel, and the le channel having the cover plate. e three
aforementioned buttons, δ, MIRROR and FLIP, also appear.
MIRROR
For a stereo instance with MIRROR disabled, only one channel is pro-
cessed. With MIRROR disabled, the cover plate is on the le, and the UI
is on the right as mentioned above. e le channel is not altered.
With MIRROR enabled, the second set of controls appear. Note that,
normally, no oset is possible between controls in MIRROR mode.
Identical settings are applied to both channels, with a ganged set of
controls for both. Also note that, in MIRROR mode, the FLIP button is
disabled.
Figure 4: RSPhaseShifter with MIRROR enabled
Unlink
In MIRROR mode, the controls are linked or ganged by default. You can
defeat the linking, to apply dierent settings to each channel.
To enable UNLINK mode, control–click the MIRROR button. In UN-
LINK Mode, the MIRROR button blinks slowly, indicating that the le
and right channel controls are no longer ganged. To deactivate UN-
LINK, click either the MIRROR or FLIP button. You can also control–
click the MIRROR button again to reënable the default LINK mode.
See Stereo Track Caveats below for more information on the implica-
tions of UNLINK mode.
FLIP
FLIP simply ips the RSPhaseShier from processing the default right
channel to the le. e user interface also ips. Again note that, in
MIRROR mode, the FLIP button is disabled.
Figure 5: RSPhaseShifter with FLIP enabled

Use Cases
In many cases, it makes sense to use this tool on just one channel, rather
than on both stereo channels. is is the case when, for example, a ste-
reo pair of ambiance mics suer because of slightly dierent distances
to the source.
1) You have a DI’d bass track, which sounds annoyingly “D.I.ish,”
and you drop the track into the mixing project so you can re–
amp. You create a great, let’s say, Ampeg SVT sound and you try
to blend the DI track with the re–amped track and it sounds aw-
ful…
Just grab the RSPhaseShier, insert it into only one mono track
of the two bass tracks, and start o with what ever frequency, let’s
say 73 Hz, and play around with the phase angle…Bang! Sudden-
ly, it sound awesome and you are done. You just need to nd the
sweet spot so that you have a fat bass and both tracks complement
each other perfectly in terms of phase.
2) Another scenario would be a set of two, let’s say stereo, distorted
guitar tracks recorded with dierent guitars or amps but playing
the same ri. ey sound awful because both are modeling–based
guitar amp simulations. You insert the stereo version of the RS-
PhaseShier into one of those pair of tracks and play around in
the same way, aer you enabled Mirror mode, so that both tracks
are ganged. Within seconds, you will nd a sweet spot where
both guitars blend perfectly, because by sweeping through the
phase angle control, you’re applying very complex comb lters
which you could not create with EQ.
3) A common situation is you have closely spaced, multi–mic’d sources,
like a snare with top and bottom mics, some instrument with two
mics, or an acoustic guitar with a mic and a piezo pickup. Just play
around with the RSPhaseShier on one of the feeds, preferably the
one which is closest to the source, such as a piezo or D.I.’d signal,
and nd the sweet spot by feel.
4) Yet another would be you’ve made a great acoustic stereo recording
and have used supporting microphones, such as room, spot or far
hall placements. To meld these into your main stereo pair, take your
mains as the phase reference, and align one supporting mic aer
the other with the mains. is is easiest if your supporting sources
are panned center and approximately the same level during phase
alignment. Aerwards, you can set gain and panning back to taste.
5) Special Effects & Sound Design: Maybe you want to create
phase sweeps to “y a sound into the mix from outer space.”
Play around, especially with RSPhaseShifter within an MS
environment, to open a creative playground for fancy phase
tricks which are dicult to achieve with other plug–ins.
6) Acoustical issues are oen an annoyance at low frequencies. RSPhase-
Shier lets you compensate for time delays between main speakers
and subwoofer channels…
a) Reduce the inuence of standing waves, or room modes, for a
loudspeaker setup in conjunction with one or more subwoofers.
b) Reduce the acoustical energy caused by low frequency cancella-
tion in live sound applications.
Stereo Track Caveats
In most stereo use cases, it makes sense to adjust the phase of just one
of two stereo channels. For that reason, in stereo you get one mono
instance on the right channel as a starting point, with the unaltered le
channel shown with its cover plate. When you want to use the MAAT
RS Phase Shier on the le channel, just press the FLIP button. If you
want to apply phase shi to both channels equally, use MIRROR mode.
Note that, normally, you cannot have oset control settings in MIR-
ROR mode; the same settings are applied to both channels. By control–
clicking on MIRROR, the two sets of controls are unlinked, operating
independently.
You may be asking yourself, “How can I have dierent treatment for
le and right channels?” In most cases, that simply doesn’t make sense
and you’d have a good chance of getting lost in your plug–in setup.
at said, unlinking via control–clicking MIRROR as mentioned above
would do the trick. You would need that function if the stereo channel
you are working on has:
a) an internal phase problem to be cured and
b) a phase problem in relation to another channel or stereo pair
To prevent you from getting lost in nding the best phase settings, we
recommend that you not unlink, and instead rst use a plug–in instance
with just one side in use, either le or right, to adjust the internal phase
relation between the two. When you’re done, just open another plug–in
instance and switch that instance to MIRROR mode. Now you can nd
the proper phase relation in conjunction with other tracks by shiing
the phase of the le and right channel, always with the same phase rota-
tion so that you can’t mess up the correct internal phase relation set by
the rst instance. is is much faster and allows individual A/B-ing of
both steps of phase correction.
e unlink mode is useful when using RSPhaseShier in an MS work-
ow where you want to create special eects. We have added this option
to make it available to you geeks, you know who you are, who simply
can’t resist going one step further.
Monaural Caveats

Page 18 of 23 Page 19 of 23
When audio engineering, it always a good idea to know where you are
with low frequency correlation. at has always been the case since un-
correlated low frequncy content, especially at large amplitude, cannot be
encoded or “cut” into a lacquer master.
But wait! Just when you thought mastering for vinyl was your only
concern at low frequencies, along comes “smart speakers.” Most are
physically small, and thus either electrically or acoustically “fold down”
stereo content to mono at low frequencies. Since by its very nature,
RSPhaseShier can modify stereo correlation, it always a good idea to
periodically check mono compatibility when using RSPS. Our 2BC mul-
tiCORR is an excellent tool for that, providing high granularity correla-
tion measurements at low frequencies.
