Front Panel Controls
“Select” pushbutton: Used to select which stream URL (1-4) is decoded, monitored
for silence and fed to the outputs.
“Def”: Recessed pushbutton used to place unit in special bootloader startup mode
for firmware reset/update.
“PM LVL”: Powered monitor level control, allows adjustment of analog output volume,
when enabled with Fixed/PM Switch.
“HdPh LVL”: Headphone output level control, adjacent to ¼” stereo headphone jack.
Defaults
The “Def” defaults button is located behind a recessed opening on the front panel.
To reset the unit to default settings, apply power and wait for the Power LED to
begin flashing, then hold down the defaults button for 10 seconds. Releasing the
defaults button will trigger a reset to defaults.
Balanced Analog Audio Output
The Streaming Sentinel 4 provides a balanced analog stereo audio output on male
XLR connectors labeled “Analog Out.”
The output connector pin-out conforms to the 3-pin XLR Wiring Standards:
Pin 1 = Ground. Pin 2 = Positive. Pin 3 = Negative.
Fixed/PM Switch
The recessed Fixed/PM switch toggles the analog audio output between a fixed out-
put level mode and a power monitor mode which allows the output level to be con-
trolled by the front panel “PM LVL” knob.
