INTRODUCTION
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.
As with the CAi series installation, for A-BUS the
two tuners in the ST2 unit must be set up as two
sources, with two source audio inputs and two IR
connections. You will need two IR link cables for
these connections.
The two IR code sets can be learned from the
ST2-RC remote into the A-LRC1 remote.
RNET-enabled System
- When the ST2 Tuner is
used with an RNET-enabled device such as the
CAV6.6 and connected to it through the Link
In/Link Out ports, 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 displayed on UNO-S2 keypads.
An additional ST2 Tuner can be connected to an
existing ST2 by using the Link Out of the first
unit into the Link In of the second unit.
RS-232
- The tuner is controlled via a PC or other
device that will communicate with the tuner
bi-directionally using the RNET protocol by the
RS-232 connection. Information on RS-232 oper-
ation is available to dealers on the Russound web
site, www.russound.com
.
Rack-Mount
- The ST2 Tuner is a single rack-unit
high and comes with a set of rack ears for rack
installation if desired.
