Reference Video (looping)
These two BNC connectors allow you to synchronize Io
LD
or Io
LA
outputs to your house reference video signal (or black burst). If you
have a sync generator or central piece of video equipment to use for
synchronizing other video equipment in your studio, then connect
its composite output here. When an Io
LD
or Io
LA
outputs video it
uses this reference signal to lock to.
AC Power
A standard male AC power socket provides connection to a power
cable (supplied separately) having three wires—one for ground. The
internal power supply is autosensing, meaning that it adjusts
automatically to either 110 or 220 VAC. The range of input AC levels
is from 100 to 240VAC at either 50 or 60Hz.
Caution: The Io
LA
and Io
LD
panels have no user-serviceable parts. An internal
fuse protects the circuitry; however, it can only be replaced by AJA service centers or
AJA dealers.

Descriptions
SDI Input and Outputs
BNC connectors are provided for one SDI input, two
SDI outputs (independent of the input), and one
looping SDI output that follows the input. SDI inputs
and outputs support video and embedded 24-bit digital
audio. SDI offers the best quality 10-bit uncompressed
video input, capture and output. If peripheral equipment
has a variety of inputs/outputs, look to see if it has SDI I/
O, and use it where possible. Most high-end professional
broadcast equipment supports SDI (VTRs, cameras,
media storage servers, etc.).
Audio/Video Analog Output
A DB15 female connector provides attachment for a breakout cable
that offers two XLR connectors for stereo balanced analog audio
output, and three BNCs for analog component or composite video
output. The connections are ideal for monitoring and/or connecting
to analog video equipment.
BNC Assignments—Component and Composite Modes
S/PDIF Audio Output
The S/PDIF connector carries 2 channels of digital audio output as
configured by Final Cut Pro. S/PDIF signals are handled internally as
24-bit digital. The connector is an RCA-style jack.
