Powering
The PIX 270i features an advanced powering system with 2 redundant DC Inputs (on rear XLR4M
connections) and PowerSafe technology. Two power sources can be attached simultaneously. When
multiple power sources are connected, the PIX 270i will use only one source at a time. The order of
precedence for power sources is:
1. DC Input 1 (Primary power source)
2. DC Input 2 (Secondary power source)
3. PowerSafe circuitry (Shutdown)
By default, the PIX 270i will operate from the Primary power source. When the Primary power
source is removed (or its voltage drops below 9V), the PIX 270i switches to the Secondary power
source without interruption, if available. When operating from the Secondary power source, if the
Primary power source voltage rises above 10.5V, the PIX 270i switches to the Primary power source
without interruption.
PowerSafe
When power is removed or voltage drops below the threshold and no Secondary power source is
available, PowerSafe circuitry will activate. The PIX 270i displays a warning, stop any active record-
ings, finish writing files, and shut the PIX 270i down. The PowerSafe Battery will power the PIX 270i
during this time. This feature ensures that files will be protected even in the event of unexpected
power loss.
