Composite Outputs (BNC)
These two low impedance outputs (Composite 1 and Composite 2) are each capable of driving up to 100 feet of RG-
58A/U coax cable. The output levels are individually adjustable between the outputs so the unit can operate as a
“composite DA” to drive a variety of equipment. The output levels and other stereo generator settings are set through
software parameters in the Encode menu. An internal jumper sets the output impedance to either 10 ohms (the factory
setting) or 75 ohms. The default setting is appropriate for the vast majority of exciter connections. However, in the
event a higher source impedance is required a jumper can be moved (one for each composite output) on the
motherboard to change the source impedance to 75 ohms. For reference, J10 is for Composite #1, and J13 is for
Composite #2.

19 kHz Sync Output (BNC)
This TTL-level 19 kHz square wave output can be used as the reference signal for any SCA generator that operates at
57 kHz or other multiple of the 19 kHz pilot frequency. This Sync output is phase and frequency locked to the stereo
pilot. When this signal is used to synchronize an external SCA or RDS generator, this locking assures that no
difference frequencies exist which may cause intermodulation components between the pilot and the SCA signal.

SCA Input (BNC)
Any SCA signal above 53 kHz can be added to the composite outputs of the Omnia-6fm by connecting the SCA
signal to the SCA INPUT connector. The SCA signal is mixed in the analog domain directly into both composite
outputs. A high-pass filter on the SCA input provides SCA to main-channel crosstalk protection. The SCA deviation
level is controlled through the SCA Level software parameter in the Encode Menu.

Ethernet Connection
The Remote Control link for your Omnia6-fm can take several forms. Dial-up modem, RS-232 serial, and TCP/IP
over 10BaseT and 100BaseT networks can be utilized. Using any of these options requires the Omnia-6 Remote
Control application that can be downloaded from http://www.omniaaudio.com, the Telos/Omnia website. The setup
and operation of the Remote Control software application is covered in detail in Chapter 6.

RS-232 Connection (DB-25F)
This connector serves two important purposes: It can be used for a local, bi-directional computer connection with
Omnia-6 Remote Control, or it can be used for troubleshooting and error code resolution. In the former case,
Omnia6-fm Remote Control software is utilized. In the latter, any terminal emulation program can be used. In either
