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.
RNET Connection
To link the ST2S to an RNET-compatible device,
use a CAT-5 passthrough 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.
IR Connections
The ST2S Tuner can be controlled by infrared
commands received through the two IR connec-
tions on the rear panel. The ST2S 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 ST2S. 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 learn-
ing-capable remotes and keypads.
If you are using an IR-controlled system from
another manufacturer, installation should be sim-
ilar. The ST2S IR codes may be learned into
many other manufacturers’ remote controls that
have learning capability for unified control over
the audio-video equipment.
ST2-KP Keypad to ST2S Connection
(Non-RNET System)
Note: ST2-KP keypads are designed for use
with IR-controlled systems (non-RNET systems).
When the ST2S Tuner is a component of an
RNET system such as CAV6.6, the RNET-system
keypads are used.
The ST2-KP connects to the ST2S 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 ST2S tuner supports
up to two ST2-KP keypads. An SA-ZX3 Keypad
Splitter can be used to add additional keypads.
Rack Mount Installation
The ST2S can be mounted in a standard compo-
nent rack using the rack ears provided. Line the
rack ear’s two rows of screw holes with the
three screw holes on the side of the tuner. Use
the screws provided to secure the rack ears
onto the unit on both sides. The ST2S tuner
should not be installed above a high heat-pro-
ducing component such as a power amplifier.
