Regulatory Notices
EMI NOTICE
This equipment has been tested and found to comply with the limits for a Class A digital device,
pursuant to Part 15 of the FCC Rules. These limits are designed to provide reasonable protection against
harmful interference when the equipment is operated in a commercial environment. This equipment
generates, uses, and can radiate radio frequency energy and, if not installed and used in accordance with
the instruction manual, may cause harmful interference to radio communications. Operation of this
equipment in a residential area is likely to cause harmful interference in which case the user will be
required to correct the interference at his own expense.
Canadian Department of Communications compliance statement:
This equipment does not exceed Class A limits per radio noise emissions for digital apparatus set out in
the Radio Interference Regulation of the Canadian Department of Communications. Operation in a
residential area may cause unacceptable interference to radio and TV reception requiring the owner or
operator to take whatever steps are necessary to correct the interference.
Avis de conformite aux normes du ministere des Communications du Canada:
Cet equipment ne depasse pas les limites de Classe A D'emission de bruits radioelectriques pour les
appareils numeriques telles que perscrites par le Reglement sur le brouillage radioelectrique etabli par le
ministere des Communications du Canada. L'exploitation faite en milieu residentiel peut entrainer le
brouillage des receptions radio et television, ce qui olbigerait le proprietaire ou l'operateur a prendre les
dispositions necessaires pour en eliminer les causes.

Introduction
This manual explains the RS20i Audio Processor setup and operation. It contains full instructions for
installing hardware and software, setting up audio playback, configuring the system, performing
maintenance and troubleshooting, and setting up and operating optional functions.
How to Use this Guide
The guide is divided into three parts. The first part covers functions for the “operator”. The second part
covers the installation, setup and other technical functions. The third part consists of appendices with
technical details such as connector and wiring diagrams.
NOTE: Technical adjustments should only be performed by a qualified installer. The
appendices provide detailed information for the installer.

About RS20i Audio Processor
The RS20i audio processor is designed for the high-end consumer audio/home theater (theater) market.
It has been engineered to deliver precise reproduction of both analog and digital sources, using the power
of 6 Analog Devices 400MHz DSPs. The standard RS20i offers 16 channels of digital and 8 channels of
analog inputs coupled to the 16 digital and 16 analog outputs. In addition to 1 S/PDIF and 2 TOSLINK
inputs, the RS20i features 4 HDMI 1.4a inputs with Blu-ray HD decoding and active loudspeaker
crossovers.
Each of the 16 channels includes:
31 bands of 1/3 octave equalization
3 bands of parametric equalization
Channel gain & phase inversion control
Individual Bass & Treble controls
Variable delay line adjustable from 0ms to 1000ms
One of the most compelling features of the RS20i is the inclusion of Dirac Live room optimization
technology. Dirac Live is a state-of-the-art digital room correction technology that improves the listener
experience by correcting for room modes and anomalies using high-resolution filter technology.
Configure once and never touch again. The result - improved musical staging, clarity of dialogue and an
enhanced listener experience.
For even greater flexibility, the RS20i Audio Processor has three product expansion slots that are
removable from the back of the unit while racked. All internal control and data lines are available to
expansion cards to service future user needs.
To get the most out of your RS20i, we suggest that you review this manual and keep it available during
system installation and initial operation.

1.2 Front Panel Controls and Indicators
Figure 1: Front Panel Controls and Indicators
The front panel contains the following controls and indicators for operating the RS20i.
Power button: Turns the unit on and off. Gently press the power symbol on the power
button cover to activate the button.
USB port: The USB port is accessed by swinging open the power button cover, left to right.
Figure 2: Power button cover, open position
Use for software updates and loading and saving of configurations. See topics 2Update
System Software From USB Device and Saving and Restoring Configuration Files on page
257 for more details.
LCD/Touch Screen: Displays system configuration and status and allows configuration
changes. Most selections can be made by touching the screen with your finger or by using a
stylus.
The LCD screen operates in two modes:
oHome screen. The operator can select inputs and mute volume from this screen.
They can also change the monitor volume and execute manual automation commands
via the popup windows. During playback, the screen displays information about the
content currently being played.
Touch screen Adjustment knob
Power button/ USB port

RS20i Installation and Operating Guide Page 15
RS20i Installation & Operating Guide Document # 9301H52900 Ver. 1.00
oSetup (System) mode. In setup mode, the screen displays menus for viewing and
adjusting operational settings by the installer. The operator does not need to enter
these menus.
Adjustment knob:Used for volume control and parameter adjustments. On the Home
screen, this knob adjusts the volume control level. However, it is used within the setup
screens to adjust values, EQ filter volume controls, and other values. When the setup screen
contains many controls, first set the focus by touching the control on the display. Then move
the knob clockwise to increase the value, or counterclockwise to decrease the value.
1.3 Powering ON the RS20i Processor
Warning: Before powering on the RS20i for the first time, verify that the correct input voltage
has been selected at the rear panel power entry module. Incorrect input voltage setting will
damage the RS20i. See section 2.5.4.
Turn ON the main power switch on the rear panel. A “hard boot” (cycling the power at the power entry
module on the rear panel) typically takes the system one minute and 15 seconds to initialize. A “soft
boot” (pressing the power button on the front panel when power has not been cycled) typically takes
about 20 seconds.
While the system is initializing, the following start up screen will appear. As initialization continues, a
progress bar will appear and status messages will show in the lower left hand corner of the screen.
Figure 3. Initial screen

RS20i Installation and Operating Guide Page 16
RS20i Installation & Operating Guide Document # 9301H52900 Ver. 1.00
When the home screen appears, the RS20i is ready.
Figure 4. Home Screen
5Note: If no image appears on the touch screen after you have turned on the power switch, check the
following:
Is the power to the equipment rack on? Has the circuit breaker to the audio rack been
tripped?
Is the power cable connected?
Is the front panel power switch lighted?
Have the fuses blown? (Note: Check that the voltage input setting on the rear panel power
entry module has been set correctly for either 115VAC or 230VAC).
Navigating through the Menus
Since the RS20i is equipped with a touch screen display, you can navigate easily through the menus by
touching any button with your finger. A non-abrasive stylus that will not scratch the screen can also be
used if you prefer.
In all screens but the Home screen, you will be presented with a button menu along the bottom of the
screen. This menu will take you to any other screen within the menu structure with a few touches of
your finger.
If the following symbol appears on the screen, it indicates that the front panel adjustment knob may be
used as a navigation tool (usually to scroll through a list or to increase/decrease values):

1.4 The Home Screen
Figure 5. Home Screen
When the system has finished booting up, the Home Screen will appear, as shown in the above example.
