ST2 SETUP AND CONNECTIONS
BASIC CONNECTIONS
Power
To power the tuner, connect the 12VDC external
power supply by inserting the power supply jack
into the power supply connection on the tuner’s
rear panel.
Audio Output
Connect one end of a dual RCA audio cable to
the Tuner 1 Audio Output connection. Keep prop-
er channel identity. Attach the other end of the
RCA cables to the source input of the audio con-
trol system. Repeat the same procedure for the
Tuner 2 Audio Output.
IR Connections
The ST2 Tuner can be controlled by infrared
commands received through the two IR connec-
tions on the rear panel. The ST2 Tuner compo-
nent contains two tuners, which must be set up
as two sources. There are two IR connections -
one for each tuner in the ST2. You will need two
IR link cables (Russound P/N 09-0508) for these
connections. There is a unique IR code set each
for Tuner 1 and Tuner 2, which allow each to be
controlled independently. These codes can be
learned from the ST2-RC remote into learning-
capable remotes and keypads. If you are using
an IR-controlled system from another manufac-
turer, installation should be similar. The ST2 IR
codes may be learned into many other manufac-
turers’ remote controls that have learning capa-
bility for unified control over the A/V equipment.
RNET Connection
T
o link the ST2 to an RNET-compatible device,
use a CA
T
-5 passthr
ough patch cable with simi-
lar wiring terminations at each end. Connect one
end of the cable to the RNET Link In of the ST2
tuner
, and connect the other end of the patch
cable to the RNET Link Out connection on the
RNET-compatible device.
ST2-KP Keypad to ST2 Connection
(Non-RNET System)
The ST2-KP connects to the ST2 tuner with
CAT-5 cable, using an RJ-45 (T568A) jack on the
tuner connection end of the cable. Be sure to
use the keypad ports for the ST2-KP and NOT
the RNET link ports. The ST2 tuner provides
connections for up to two ST2-KP keypads. An
SA-ZX3 Keypad Splitter can be used to add addi-
tional keypads.
Note: ST2-KP keypads are designed for use
with IR-controlled systems (non-RNET systems).
When the ST2 Tuner is a component of an RNET
system such as CAV6.6, the RNET-system UNO-
S2 keypads are used
Rack Mount Installation
The ST2 can be mounted in a standard compo-
nent rack using the rack ears provided. Line up
the rack ear’s two rows of screw holes with the
thr
ee scr
ew holes on the side of the tuner
. Use
the scr
ews pr
ovided to secur
e the rack ears
onto the unit on both sides. The ST2 tuner
should not be installed above a high heat-pr
o
-
ducing component such as a power amplifier
.
