Audio Cards
The JetStream MINI will accept from one to eight audio cards in slots A-H, which can be either
analog or digital.
JSM-AIN-RJ Analog Input Card
The JSM-AIN-RJ card provides 8 mono or 4 stereo inputs using RJ-45 connectors, following the
StudioHub+ wiring standard. Trim pots to the left of the slot provide precise level adjustment. All
JSM-AIN-RJ cards ship from the factory calibrated to a reference of +4 dBu. The reference level
may also be set using AE Config software, although adjustments made to the analog cards in AE
Config may not be as clean or as precise as by using the trim pots. The top LED on each connector
will blink as an audio meter when audio is present on the left channel and the bottom LED will
blink when audio is present on the right.
 TIP: The trim pots must be used for gain changes of more than 4 dB to preserve the
signal to noise ratio!

the left of the slot provide precise level adjustment. All JSM-AIN-RJ cards ship from the factory
calibrated to a reference of +4 dBu. The reference level may also be set using AE Config software,

using the trim pots. LED lamps above the connector will flash as a meter to show audio presence.
