INTRODUCTION
DESCRIPTION
Thank you for choosing the Russound ST2 Smart
Tuner. Whether you are adding radio to an exist-
ing system, expanding a CAi Series system or
taking advantage of the CAV6.6’s robust RNET™
communication link, the ST2 Tuner is designed to
meet your needs.
The ST2 Tuner is like having two radios in one.
The two AM/FM tuner modules share one set of
controls and display on the front of the unit, but
each runs independently. This arrangement
allows two different broadcasts at the same time
in a multi-room audio distribution system.
In addition to the traditional AM/FM broadcast
tuner function, the ST2 Tuner can store up to 72
favorites, or memory presets. These are stored
in groups of six called banks. There are six
banks for each tuner. Each preset and each bank
can be given a custom name of your choice.
The ST2 Tuner can be controlled from the front
panel or by the dedicated ST2-KP tuner keypad.
It can also be controlled by the ST2-RC IR remote
aimed at the tuner’s front panel IR receiver. The
ST2-RC IR codes can be learned into any IR
learning remote control for easy system integra-
tion. It can also be controlled by IR signals
received through the IR connections on the rear
panel from IR repeating system commonly used
in distributed audio systems.
If the ST2 Tuner is part of an RNET-enabled sys-
tem such as the CA
V6.6-S2 system, the tuner
can be controlled through an UNO-S2 keypad.
The ST2 Tuner also has an RS-232 port to sup-
port fully bi-directional integration into whole-
house control systems such as Crestron
®
and
AMX
®
.

INSTALLATION APPLICATIONS
RNET-enabled System
When the ST2 Tuner is used with an RNET-
enabled device such as the CAV6.6 and is con-
nected to it through the Link In or Link Out port,
the tuner will be controlled by the CAV6.6
through the UNO-S2 keypad. Through RNET,
tuner information such as Tuner 1 or 2, station
frequency, preset names and AM/FM band is dis-
played on UNO-S2 keypads. An additional RNET
device can be connected to an existing ST2 by
using the Link Out of the first unit into the Link In
of the second unit.
Before using the ST2 tuner with the
CA
V6.6, you must assign sour
ce numbers
to Tuner 1 and 2 in the ST2 Setup Menu
AND complete the CAV6.6’s Source Setup
pr
ocedure to identify the tuner as a
“Peripheral“ device and assign Sour
ce
Numbers. The CAV6.6 requires firmware
version 2.00.01 or higher to control each
tuner thr
ough RNET
