Carefully remove the RCS 2.2 XP and accessory kit from the carton and visually
check for shipping damage. Contact both the shipper and TacT Audio immediately
if the unit shows any sign of damage from rough handling. All TacT Audio equipment is carefully inspected before leaving our factory.
KEEP SHIPPING CARTON AND PACKING MATERIALS for future use or in the
unlikely event that the unit needs servicing. If this unit is shipped without the
original packing, damage could occur and void the warranty.

The RCS 2.2 XP has four times the processing power of the famous TacT RCS
2.0 and even better AD and DA conversion. This now combined with new features and a more user-friendly interface takes TacT Audio’s room correction to
new heights. The RCS 2.2 XP has no noise and extremely low distortion, yielding
amazingly transparent accurate sound. Every eff ort has been made to make this
preamplifi er the best that money can buy. Add to this the latest evolution of TacT
Audio’s room correction technology and the result is absolutely staggering.
TacT room correction technology has been praised by the press all around the
world. Comments like “Wholesale improvement in sound quality” have become
a standard phrase for reviewers describing the results that can be achieved with
TacT’s room correction. Now we have taken room correction technology even
further, not only in terms of processing power, but also in terms of the measurement and correction systems. The measurement is now done with a triple pulse
for each acquisition. This increases the measurement resolution in both the time
and frequency domains. Correction resolution is now four times higher than found
in the original RCS 2.0.
One of the most exciting features of the RCS 2.2 XP is its separate subwoofer
output. The RCS 2.2X P can be used with one or (preferably) two subwoofers. An
electronic crossover can be set with a frequency between 60 and 400 Hz and a
slope between 12 dB/octave and 60 dB/octave to split the audio signal between
the main and subwoofer outputs. The correction software aligns the sub-woofer(s)
with the main speakers in the time domain and in the frequency domain, for completely seamless integration surpassing even the best single-box systems.
CAUTIONCAUTION
With the RCS 2.2 XP, you can add subwoofers to an existing High End speaker
system for substantial sonic improvements. Preferably, the subwoofers should be
placed in the corners behind the main speakers. Corner placement of the subwoofers will yield much higher effi ciency with signifi cantly reduced low-frequency
distortion. But more importantly, the transfer of energy from the sub to the listening
position will be much more direct, resulting in vastly improved impulse response.
The room correction system will easily compensate for the frequency response
variations of the subs introduced by corner placement. It will delay the main
speakers for perfect time alignment to within 1/8 of an inch.
The RCS 2.2 XP off ers you the opportunity to add subwoofers to a system and
improve the transient response tremendously at the same. This contrasts sharply
with the normal result of adding subwoofers to a system: slow – undefi ned bass
with lots of frequency and time behavior problems. If the separate subwoofer
outputs are not used, then the RCS 2.2X will use all the processing power on the main
speakers.

Dynamic Room Correction (DRC) ® is new technology developed by Tact Audio
Inc. over past two years. This groundbreaking brings the science and art of Room
Correction, and specifi cally Tact room correction products, to yet another level.
When we introduced our fi rst RCS system (the Tact-2.2 in the late 90’s) we were
fully aware that we were embarking on a long term research process in the new
exciting fi eld of room acoustics correction. As a result of this research effort we
brought to the market products such as Tact-2.0 S two channel RCS preamp, the
Tact-2.2 X two channel preamp with RCS on two main and two subwoofer channels, and the TCS MKII ten channel theater correction system. All these systems
offer RCS technology not found in any other product on the market. Our continued research combined with enormously valuable feedback from our customers
has resulted in this new technology that we named Dynamic Room Correction
(DRC)®.
Why do we call it Dynamic Room Correction (DRC)?
The reason we call it DRC is that the target curve used to compute correction fi lters dynamically changes with the master level control. In another words, for every
0.1 dB of level change the system uses a new target curve to compute room cor-
rection fi lters. What makes this dynamic is that all computations and adjustments
are done on the fl y without any interruption to the music you listen to.
Why do we need Dynamic Room Correction (DRC)?
It is well known fact that humans do not here all frequencies at the same level.
It is also known that our ears are more sensitive to frequencies between 2000
and 5000 Hz than to frequencies bellow 2000 Hz and above 5000 Hz. In addition to this our hearing sensitivity changes with sound pressure level (SPL). This
human hearing property was fi rst discovered and experimentally confi rmed by
Fletcher and Munson at Bell Laboratories in 1933 and later refi ned by Robinson
and Dadson in 1956. Their work resulted in a family of equal loudness curves
(contours), widely known as Fletcher-Munson equal loudness curves. A sample of
Fletcher-Munson loudness curves is shown in the fi gure bellow.
On the graph there are 12 curves numbered from 0 to 110. These numbers represent the loudness level in phons. A Phon is a unit used to describe the loudness
level of a given sound. The reason for introducing the loudness unit is that two
sounds with the same SPL (dB) do not necessarily have the same perceived loudness. Phon is equal to SPL in decibels at 1000 Hz. For example, 80 phons means
as loud as 80 dB, 1000 Hz tone.
Equal loudness curves represent the SPL that different frequencies need to have
in order to be perceived as two tones of equal loudness. For example, a 200 Hz
tone at SPL of 50 dB will have the same perceived loudness as a 1000 Hz tone at
SPL of 40 dB. In this case both 200 Hz and 1000 Hz tones have a loudness of 40
phons, and they both belong to the 40 phons equal loudness curve.
As it can be seen from the graph, in comparison to frequencies between 2000
and 5000 Hz, it is intrinsically harder for us to hear very low frequencies (below a
few hundred Hz) and to a lesser extent very high frequencies (above 7000 Hz). At
higher listening levels this difference gradually becomes smaller and smaller and
curves become fl atter.
Tact Audio
Traditional Tact room correction systems use one target curve that allows for
full range 20-20,000 Hz room corrections. Once selected, the same target curve
(same set of correction fi lters) was used at all listening levels. This approach did
not take in account the fact that our sound perception, as described by FletcherMunson curves, is frequency and level dependent. Many of our customers have
realized this fact and they have used the nine correction presets (available on all
our RCS products) to program 2.0 S, 2.2 X and TCS MKII with nine different target
curves each corresponding to a different listening level. In this way they were able
to take into account the equal loudness curve effect by switching to new target
curves as the master level changes.
Thus for a number of reasons it is clear that we need a room correction system
that will perform room acoustics correction and at the same time dynamically
change the target curve (correction fi lters) as the system listening level changes.
How does it work?
Dynamic Room Correction (DRC) offers a very sophisticated way of handling a
multi target curve approach to solving equal loudness curve problem. The system
is based on one reference target curve and eight additional target curves called
dynamic target curves. The reference target curve is used to perform basic reference room correction. Dynamic target curves are labeled 0, -6, -12, -18, -24, -30,
-36 and –42 dB and are combined with the reference target curve to obtain the
fi nal target curve used to calculate correction fi lters.
For example, if the master level reads –10.3 dB (89.6 on the relative readout) the
system will use the –6 dB and the –12 dB dynamic target curves and by interpolation will calculate a target curve corresponding to –10.3 dB. After that the system
will combine the 10.3 dB target curve with the reference curve to obtain the fi nal
target curve that is then used to calculate the correction fi lters. New correction
fi lters are loaded into the signal path as the music is playing and the new correction takes effect in a split of a second. The same process repeats again for any
new master level setting.

ROOM CORRECTION
Tact-2.2 XP can now perform room correction automatically from the 2.2 XP front
panel user interface, without the need for an PC software.
The automatic room correction feature is designed to perform the entire room correction process without using a PC interface. The Tact-2.2 XP has suffi cient DSP
processing power to perform room measurement, crossover fi lter design, target
curve generation and correction fi lter calculation. The entire process is controlled
from the 2.2 XP front panel DRC-RCS menu. Target curve and crossover fi lter
adjustments can be made on the fl y while the music is playing. Users can, for example, specify a boost at low frequencies or a roll-off at high frequencies. Values
of the ‘low’ and ‘high’ frequencies can also be adjusted.
PC based room correction requires that the 2.2 XP is connected to the RS232 port
of a PC. PC software is used just as a GUI (graphical user interface) to provide
the user with a graphical presentation of the correction process. After the room
response measurement is completed, the room frequency response for all measured channels can be displayed on the screen. Crossover fi lters and actual correction fi lters can be viewed. The displayed graphs provide valuable information
that helps users design their own optimum target curve.
The Tact-2.2 XP memorizes two sets of target curves: computer generated and
automatically generated target curves. When the automatic feature is turned OFF,
the 2.2 XP will use a computer generated set of target curves. When the automatic
feature is turned ON, the 2.2 XP uses target curves generated by the 2.2 XP front
panel automatic correction feature.
When the 2.2 XP is connected to a PC and the automatic feature is enabled, automatically generated target curves will be uploaded into the RCS/DRC screen.
The curves can than be saved or modifi ed. Modifi ed curves can than be loaded
back into the 2.2 XP. However, the uploaded curves will not take effect until the
automatic feature is disabled. Any target curve uploaded to 2.2 XP is saved as
a PC generated target curve and takes effect only when the automatic feature is
disabled. In another words, if a target curve is to be modifi ed by the PC software,
the automatic correction feature has to be disabled.
This following describes the automatic room correction process for all 2.2 XP
operating modes.

memory, please refer to the Microphone section of the PC software manual.
AVG This is a very important measurement parameter. It equals the number of
measurements that are averaged prior to being saved. The averaging process
reduces the effects of random environmental noise. Typical Average values go
from 10 to 30.
Tact Audio
DELAY. If you do not want to be in the room while measurement is in progress,
set this parameter to a few seconds to allow you to exit the room. For example, if
DELAY = 10 the system will wait for 10 seconds before it starts pulsing.
PULSE. This parameter sets the relative level of the output measurement pulse.
Minimum level is 1% and maximum level is 100%.
FILE. Use this option to assign a File number to the measurement you are just
about to perform. At the end of the measurement process, the measurement data
for all four channels will be saved in the selected File number. Tact-2.2 XP supports up to seven measurement fi les. In another words you can save up to seven
different measurements in 2.2 XP internal memory.
Use L, R, SL and SR options to select (enable) a channel for measurement.
Channels are labeled as L for left, R for right, SL for subwoofer left and SR for
subwoofer right channel. Selected (enabled) channels are marked by a rectangle.
To select or deselect a channel place the cursor over desired channel and press
ENTER button.
In most cases, factory presets are optimum and users can proceed directly with
peforming actual measurements. To initiate the room measurement process, click
on the START button. The following screen will be displayed:

4. Enable automatic room correction. In the DRC-RCS screen (Fig. 3), select
correction preset 1. Make sure that crossover fi lters are enabled and proper
crossover frequency is selected. Crossover fi lters can be adjusted at any time
even after you enable the automatic feature. Click on the AUTO-OFF menu option
to enter the Auto Correction screen (Fig. 5). Note that in bypass mode the AUTOOFF(ON) menu option is not displayed.
Fig. 5 Auto Correction screen.
In the Auto Correction screen click on the AUTO-OFF menu option to display
AUTO-ON and then click on the SET option to activate automatic room correction. In a split of a second the 2.2 XP will calculate target curves based on LF,
HF, crossover fi lter selection parameters and measurement data as saved in
measurement fi le 1.
You are ready to perform your fi rst listening test. Use LF parameters to add gain
or attenuation at frequencies bellow the frequency as displayed in LF parameter
bloc (1). Use HF parameters to add gain or attenuation to frequencies above the
frequency as displayed in HF parameter block (2). In this way you can shape target curves to match your specifi c listening needs.

MIC FILE. This fi eld displays the microphone fi le name used to perform microphone calibration. The microphone calibration fi le data is saved in 2.2 XP internal
memory. For more details on how to transfer microphone calibrations fi le to 2.2 XP
memory, please refer to the Microphone section of the PC software manual.
AVG This is a very important measurement parameter. It equals the number of
measurements that are averaged prior to being saved. The averaging process
reduces the effects of random environmental noise. Typical Average values go
from 10 to 30.
DELAY. If you do not want to be in the room while measurement is in progress,
set this parameter to a few seconds to allow you to exit the room. For example, if
DELAY = 10 the system will wait for 10 seconds before it starts pulsing.
PULSE. This parameter sets the relative level of the output measurement pulse.
Minimum level is 1% and maximum level is 100%.
FILE. Use this option to assign a File number to the measurement you are just
about to perform. At the end of the measurement process, the measurement data
for all four channels will be saved in the selected File number. Tact-2.2 XP supports up to seven measurement fi les. In another words you can save up to seven
different measurements in 2.2 XP internal memory.
Use L, R, SL and SR options to select (enable) a channel for measurement.
Channels are labeled as L for left, R for right, SL for subwoofer left and SR for
subwoofer right channel. Selected (enabled) channels are marked by a rectangle.
To select or deselect a channel place the cursor over desired channel and press
ENTER button.

After the measurements are completed, click on the EXIT option and then click
on the MENU button to go back to the DRC-RCS screen (Fig. 3). At any time during the measurement process you can click on the CANCEL option to cancel the
