Introduction

Congratulations on your purchase of your RCS 2.2X. Y ou 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 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

2.2X has no noise and extremely low distortion, yielding amazingly transparent
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.

CAUTIONCAUTION

Room Correction

System

Separate Subwoofer

Control

T acT 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 2.2X 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.

Flexible DSP’s

8 T act Audio

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

Modular design

True Upgradeability

The internal layout of the RCS 2.2X is completely modular . All of the expensive com­ponents such as DSP’s, D/A and A/D converters are a plug-in type and are placed on
a motherboard. This allows for easy and inexpensive future upgrades. Even the rear­panel, including the sockets, can be exchanged to accommodate future interfaces.

The front-panel and DSP’s are 100% software driven, and improvements or new fea­tures 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 ([e-mail]).

RCS 2.2X Connections

Digital input

The RCS 2.2X has 5 digital inputs:

- Three RCA (S/PDIF)

- One AES/EBU (XLR)

- One TosLink (S/PDIF)

All of the digital inputs supports PCM audio data with sampling rates from 32kHz to
96kHz /16-24 bits however, the AES/EBU and RCA/coaxial input also supports

192kHz.

CAUTIONCAUTION

Digital output 1

main channels

The RCS 2.2X has three digital outputs for the main channels :

- One RCA (S/PDIF)

- One AES/EBU (XLR)

- One T osLink

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 T acT digital amplifier
or external DA converter .

RCS 2.2X Connections

Digital output 2

subwoofers

The RCS 2.2X has three digital outputs for subwoofer(s) :

- 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. (T osLink 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 DA converter.

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.
