Power
To power the tuner, connect the 12VDC external
power supply to the unit by inserting the power
supply jack into the power supply connection on
the back panel.
The ST2 Tuner power commands are global.
The ST2 component is powered on and off by
toggling the power switch on the front of the
tuner. The unit must be powered on before
receiving commands from a keypad or remote
control. When either Tuner 1 or Tuner 2 is pow-
ered off by the ST2-RC remote, the UNO-S2 key-
pad or the UNO-LRC1 remote, the command
powers down both Tuner 1 and Tuner 2.
However, the entire unit remains in standby until
the power switch is toggled to OFF.
Any key press will wake up the tuners from
standby. This is a key press from the tuner front
panel, ST2-RC remote, UNO-S2 keypad or UNO-
LRC1 remote. When the ST2 tuner is powered
back on, it will return to the last tuner, bank, fre-
quency and other settings that were in use when
the tuner was powered down.
AM Antenna
Connect the included loop antenna for AM recep-
tion to the back panel, attaching the GND
(ground) and AM ends to the appropriate con-
nections for Tuner 1. Repeat procedure for the
Tuner 2 AM antenna.
It is recommended to use an external outdoor or
attic-mounted long wire antenna for best per-
formance for AM reception. Use a 300-ohm to
75-ohm balun at the AM connection on the
tuner, and attach the 75-ohm coax cable to the
balun.
FM Antenna
Attach the included FM antenna to the Tuner 1
FM COAX connection on the back panel by push-
ing the F-type quick-connect termination of the
antenna onto the FM connection. Repeat the
same procedure for the Tuner 2 FM antenna. A
75-ohm splitter may be used to connect both
tuners to one antenna.
It is recommended to use an external outdoor or
attic-mounted long wire antenna for best per-
formance for FM reception. Attach the desired
length of 75-ohm coax cable directly to the FM
connection on the tuner.
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 dis-
tribution system. Repeat the same procedure for
the Tuner 2 Audio Output.
RNET Connection
Using a CAT-5 patch cable with T568A wiring
standard RJ-45 terminations, 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 CAV6.6 or
other RNET-compatible device.
