1.
Using a stereo RCA-stereo male 3.5mm mini
plug patch cable with gold ends, connect
the left and right line level audio outputs of
a CD player, MP3 player, cable box or other
audio device to the Aux In on the SA 2.1
Receiver Front Panel as shown in
Figure 15
.
NOTE:
If using the SA 2.1 system to broadcast
surround speaker channels, connecting a
source to the SA 2.1 Receiver Aux In is not
recommended. Surround speaker levels
should be set to specific levels that are in
balance with the front speakers. Select-
ing the source connected to the Aux In
and adjusting the volume for that source
will adversely affect the front/rear speaker
balance when the surround speakers are
selected.
This connection will allow switching the SA
2.1 Receiver to a local audio source or the
main source broadcast by the SA 2.1 Trans-
mitter.
The Aux In is selected by pressing the Input
button on the SA 2.1 IR Remote.
Position the Transmitter and Receiver
After all connections to the SA 2.1 Transmitter and Receiver have been made, place the Transmitter and Re-
ceiver in their normal operating locations.
Antenna
With the SA 2.1 Transmitter and Receiver in their normal operating positions, confirm that the antennas are ex-
tended in a fully upright position as shown in the illustrations.
Power Supply Connections
After all connections to the SA 2.1 Transmitter and Receiver have been made and confirmed, connect the
included power supplies to the appropriate device.
1.
Connect the
18VDC 400mA
supply to the 18VDC 400mA jack on the
SA 2.1 Transmitter
.
2.
Connect the
24VDC 4.75A
supply to the 24VDC 4.75A jack on the
SA 2.1 Receiver
.
3.
The Front Panel LED’s on both units will illuminate solid red (standby) until an audio signal is sensed by the SA
2.1 Transmitter Speaker Level or Pre-amp Level Inputs.
4.
Confirm all other system components are connected to AC power.
5.
SA 2.1 system is ready for operation.
Final Setup
Turning the SA 2.1 ON/OFF
ON -
When properly set up, the SA 2.1 system will turn ON/OFF automatically. The SA 2.1 Transmitter Pre-Amp
and Speaker Level Inputs feature audio sensing circuitry that instantly and automatically turns the SA 2.1 system
ON when audio signals are detected.
1.
Turn on all system components (Audio receiver/amplifier, CD player, Blu-ray player, MP3 player, etc.) Select
a source on the audio receiver/amplifier and play that source.
The LEDs on the SA 2.1 Transmitter and Receiver front panels should illuminate solid blue. This will indicate
that the SA 2.1 Transmitter and Receiver are communicating normally. (RF lock)
If the LEDs do not illuminate solid blue (solid red or slow blue flash) confirm all connections, confirm all system
devices are connected to power and turned on and confirm that the selected source is playing.
If the LEDs still do not illuminate solid blue, check for possible interference from other devices that may be
interfering with the RF (radio frequency) signals between the Transmitter and Receiver. Interference can be
caused by large metal objects such as steel beams and refrigerators or radio interference from other elec-
tronic devices such as cordless telephones or other wireless devices.
Repositioning the Transmitter and/or Receiver may help in eliminating RF interference that is affecting SA 2.1
system performance. Also see section:
Operating the SA 2.1/ID Codes
.
OFF -
The SA 2.1 system will automatically turn OFF (standby) when no audio signals have been detected at the
Transmitter Pre-Amp or Speaker Level Inputs for more than ten minutes. The LEDs on the SA 2.1 Transmitter and
Receiver will illuminate solid red to indicate standby.
Front Panel LEDs
The LEDs on the SA 2.1 Transmitter and Receiver will change state (solid/flash) and color to indicate current
operating status.
