Introduction  
Congratulations on your purchase of your RCS 2.2X. You have now acquired the most  
advanced stereo Preamplifier / Room Correction System ever developed!  
The RCS 2.2X has four times the processing power of the famous TacT RCS 2.0 and  
even betterAD and DAconversion. This now combined with new features and a more  
user-friendly interface takes TacTAudio’s room correction to new heights. The RCS  
2.2X has no noise and extremely low distortion, yielding amazingly transparent  
CAUTION  
accurate sound. Every effort has been made to make this preamplifier 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.  
Room Correction  
System  
Separate Subwoofer  
Control  
One of the most exciting features of the RCS 2.2X is its separate subwoofer output.  
The RCS 2.2X 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.  
With the RCS 2.2X, 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 efficiency with significantly 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 2.2X offers 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 – undefined 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.

Introduction  
The internal layout of the RCS 2.2X is completely modular. All of the expensive com-  
ponents such as DSP’s, D/AandA/D converters are a plug-in type and are placed on  
a motherboard. This allows for easy and inexpensive future upgrades. Even the rear-  
panel, including the sockets, can be exchanged to accommodate future interfaces.  
Modular design  
The front-panel and DSP’s are 100% software driven, and improvements or new fea-  
tures can be loaded through the RS232 port with firmware upgrades. It is our policy to  
offer software upgrades at no cost, and we therefore encourage you to fill out and  
submit the enclosed registration card by fax or email ([email protected]).

RCS 2.2X Connections  
The RCS 2.2X has 5 digital inputs:  
Digital input  
- Three RCA (S/PDIF)  
- OneAES/EBU (XLR)  
- One TosLink (S/PDIF)  
All of the digital inputs supports PCM audio data with sampling rates from 32kHz to  
CAUTION  
96kHz /16-24 bits however, the AES/EBU and RCA/coaxial input also supports  
192kHz.  
Digital output 1  
main channels  
The RCS 2.2X has three digital outputs for the main channels :  
- One RCA (S/PDIF)  
- OneAES/EBU (XLR)  
- One TosLink  
All outputs are 24-bits at 44.1, 48, 88, 96 or 192 kHz sampling rates (TosLink does  
not support 192kHz). The output sampling rate is set in the “DOUT” menu.  
The main channel output is used for your main speakers or for Mid/High frequencies  
when used with subwoofers. Connect one of these outputs to a TacT digital amplifier  
or external DAconverter.

RCS 2.2X Connections  
The RCS 2.2X has three digital outputs for subwoofer(s) :  
Digital output 2  
subwoofers  
- one RCA (S/PDIF)  
- one AES/EBU (XLR)  
- one TosLink  
All outputs are 24-bits at 44.1, 48, 88, 96 or 192 kHz sampling rates. The output  
sampling rate is set in the “DOUT” menu. (TosLink does not support 192kHz)  
The sub output is for your subwoofer(s) and can be configured for either mono or  
stereo. Use the “MODE” menu to set the appropriate output mode 2.0, 2.1, or 2.2.  
Connect one of these outputs to a TacT digital amplifier or external DAconverter.  
Optional modules  
The RCS 2.2X is designed to accommodate virtually any input and output needed  
without adding extra cost for features certain users might not use. There are therefore  
3 optional modules that can be installed:  
-ADC-converter module for analog inputs such as a Tuner,  
Cassette deck, VCR etc.  
- DAC-converter module for main channels, for example  
when the RCS 2.2X is used with traditional analog  
amplifiers  
- DAC-converter module for subwoofer(s), for example when  
the RCS 2.2X is used with analog self-powered  
subwoofer(s)  
These modules are based on the latest 24-bits/192kHz state-of-the-art technology  
and offer performance far beyond that of most stand-alone converters. Due to the  
modular design of the RCS 2.2X, these modules can be added any time or exchanged  
if upgrades should become available.

DOUT menu  
The DOUT menu offers two options. Option “1” will force the system to output Left  
and Right channel signals at digital output 1, and Left SUB and Right SUB channel  
signals at digital output 2. Option “2” will output Left main channel and Left  
subwoofer at digital output 1 and Right main channel and Right subwoofer at digital  
output 2.  
This menu is designed to support TACT digital amplifiers. In many stereo systems  
digital amplifiers are used to power both main channels and subwoofers. You would  
use option “1” if both Left and Right channel are connected to the same amplifier,  
and both Left SUB and Right SUB channel are connected to the same amplifier. In  
the case where one main channel and one SUB are connected to the same  
amplifier you need to select option “2”. To select one of the options, use the “LEFT”  
or “RIGHT” navigational buttons to position the cursor over the desired option and  
press the “ENTER” button to select it.  
NOTE: This menu has no affect on the analog outputs.  
AMP menu  
The AMP menu is designed to allow the RCS 2.2X to interface with the TacT M2150  
or S2150 digital amplifiers. The RCS 2.2X can control multiple digital amplifiers.  
This setting should be ENABLED only if you have a Tact digital amplifier  
attached to the RCS 2.2X.  
For example, one amplifier can be used for main left and right channel and second  
one can be used for the left and right subwoofer channels. If two TacT digital ampli-  
fiers are connected, both options (1) and (2) should be set to ENABLED. If one Tact  
digital amplifier is connected only one option should be set to ENABLED and the  
other one should be set to DISABLED. Enable should only be set for the output  
that uses Tact digital amplifiers.  
To change the settings use the “UP” and “DOWN” navigational buttons to highlight  
the option and then press the “ENTER” button to change the setting.
