INTRODUCTION
IR-controlled System
CAi Series -
The ST2 Tuner can be controlled by infrared
commands received through the two IR connec-
tions on the rear panel. The ST2 contains two
individual tuners, which makes it act as two
sources in the CAi system. There are two source
audio outputs and two IR connections - one for
each tuner in the ST2. You will need at least one
IR link cable (Russound P/N 09-0508) for these
connections (one is supplied with each CAi sys-
tem). There are two unique IR code sets for
Tuner 1 and Tuner 2, which allow each to be con-
trolled independently from either IR connection.
These codes can be learned from the ST2-RC
remote control into the CA-LRC1 remote control
and/or the DSC and DAN IR learning keypads. If
you are using an IR-controlled system from anoth-
er manufacturer, installation should be similar.
The ST2 IR codes may be learned into many
other manufacturers’ remote controls that have
learning capability for unified control over the A/V
equipment.
A-BUS
®
System -
The ST2 Tuner can be used in an A-BUS system
with an audio distribution hub such as the
A-H484 and IR-repeating keypads such as the
A-KP2. The connections on the rear panel are
designed to receive IR signals from a repeating
system commonly used in A-BUS distributed
audio systems.
For A-BUS applications, as with the CAi series
installation, the two tuners in the ST2 unit must
be set up as two sources, with two source audio
inputs and two IR connections. Y
ou will need two
IR link cables for these connections. The two IR
code sets can be learned from the ST2-RC
r
emote into the A-LRC1 r
emote control.
Note: Optional ST2-KP keypads can be used to
provide control for the ST2 Tuner and are
designed to be used with IR-controlled systems.
RS-232 Controlled System
The ST2 Tuner can be controlled using the RNET
protocol provided via the RS-232 port on the
rear panel. It can also be controlled by any
RS-232-enabled control system (e.g., Crestron,
AMX). Information on RS-232 operation is avail-
able to dealers on the Russound web site,
www.russound.com.
