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 recorder‟s internal battery.
Using an External Power Source
When the 12 VDC input is connected to a power source, it supplies power to the recorder when its power
switch is in the „OFF‟ position.
If batteries are installed in the recorder and external power is connected, the unit 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 Recorder
The adapter can be used to power the recorder 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 recorder‟s output setting (
Timecode Output Enable page {p.26}) determines if audio
or timecode is sent through the output.
Timecode Input
The timecode input is used to jam the recorder‟s timecode generator. If the auto-load function ( Timecode Jam
Mode page {p.26}) is enabled, the timecode input of the stereo adapter can be used.
Operation of the STAxxx
For the stereo adapter to operate, the recorder must select the stereo setting ( Record Format page {p.23}) and
external ADC ( ADC Location page {p.28}) must be selected.
Host Unit functions
Selecting the stereo setting causes the recorder to combine the two input signals together and transmit them on
one frequency. The ADC selection:
INTERNAL
– selects the internal mic input,
EXTERNAL
– selects the
stereo adapter audio.
