Powering the STAxxx

Connection of 12 VDC power to the stereo adapter is optional. If no power source is connected to the STAxxx,

it operates from the unit‟s internal battery.

Using an External Power Source

When the 12 VDC input is connected to a power source, it supplies power to the unit when its power switch is in

the „OFF‟ position.

If batteries are installed in the unit and external power is connected, it will not be able to power down unless an

external power switch is available to remove the external power.

Using the STAxxx to Power the Unit

The adapter can be used to power the unit while it is in Mono mode and using a Mic-level input.

The Audio/Timecode Output Connection

The audio output connection is used to monitor the audio functions of its host unit or to allow timecode to pass

through the STAxxx. The unit‟s output setting (TC Output Enable page {p.39}) determines if audio or timecode

is sent through the output.

Timecode Input

The timecode input is used to jam the unit‟s timecode generator. If the auto-load function (TC Jam Mode page

{p.39}) is enabled, the timecode input of the stereo adapter can be used.

Operation of the STAxxx

For the stereo adapter to operate, the Operator must select STEREO (UHF Signal Format page {p.36}) and

select STA-100 or STA-150 (as appropriate) (ADC Select page {p.41}).

Host Unit functions

Selecting the stereo setting causes the unit to combine the two input signals together and transmit them on one

frequency. The ADC selection: INTERNAL – selects the internal mic input, STA-100 or STA-150

selects the appropriate stereo adapter‟s audio.
