KONA 3 Installation and Operation Manual — Cable Connections
Connector
Descriptions—
Cables and
K3-Box
Connectors on the standard cable set are labelled as to their function for easy
installation and maintenance. Similarly, connectors on the optional Breakout Box are
also labelled.
8 Channel Digital AES/EBU Audio Inputs And Outputs
When using the standard cables, XLR connections are provided for digital AES/EBU
audio input/output. Four female XLR connectors are provided for audio input and
four male for audio output. Each XLR carries two channels. XLR connectors are
labelled as to input/output and channels.
The optional Breakout Box provides both BNC and XLR audio connections on the
front panel.
Note: XLR connections are digital and cannot be used with analog equipment
having XLR connectors.
Analog 2 Channel Unbalanced Audio (Breakout Box only)
On the optional K3-Box are two analog output connectors, one for each channel.
These connectors are RCA-style phono jacks.
RS422 Machine Control
A DB9 connector provides connection to VTRs, digital disk recorders, and other
devices using RS422 device protocol. For the breakout cable the connection is male
and for the breakout box the connector is female. (Connector pinout is listed in
Appendix A: Specifications.)
SDI Input and Outputs
Mini-connectors are provided for two SDI inputs and two SDI outputs for single or
dual-link. A cable with four Mini-connectors on one end and four BNCs on the other
end is provided for connecting equipment to the SDI inputs and outputs. This cable
is also used to interconnect between the KONA 3 board to the optional K3-Breakout
Box.
KONA 3 has up to 4 video outputs in SD and up to 3 outputs in HD—2 SDI
outputs that are used for both high-definition and standard-definition (SD/HD-SDI),
and an analog video output (configuration of this three BNC cluster is discussed later
with regards to component, composite and Y/C). Each of the three outputs is
independently switchable between HD and SD. For example, if you are working in
HD, you can have simultaneous HD-SDI, SD-SDI, and HD-component analog
output.
SDI inputs and outputs support video as well as 16-channels of embedded 24-bit
digital audio. Use SDI wherever possible for 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.).
Note: In the past manufacturers have used separate I/O connections for standard-
and high-definition SDI because the circuits were different. On KONA 3 we use the
same connectors for both HD and SD-SDI (both input and output) due to our dual
rate chipset which supports both HD and SD.
