Connector

Descriptions—

Cables and KL-box

Connectors on the standard cable set are labelled as to their function for easy installation and

maintenance. Similarly, connectors on the optional KL-box are also labelled.

SDI Input and Outputs

BNC connectors are provided on the KONA LHe Plus card endplate for one SD-SDI or HD-SDI

input and two SDI outputs (independent of the input). The SDI input and outputs support

video and 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.).

2-Channel Digital AES/EBU Audio Inputs And Outputs

One female XLR connector is provided for the channel 1 and 2 inputs, while a male XLR

connector carries channel 1 and 2 outputs. AES/EBU signals are handled internally as 24-bit

digital.The optional KL-box also provides XLR audio connections on the front panel.

Note: AES XLR connections are digital and cannot be used with analog equipment having

XLR connectors.

Analog 2 Channel Balanced Audio

Two sets of analog XLR connectors, one for each channel, support balanced audio

connections. Male XLRs are provided for outputs and female XLRs are provided for inputs.

Balanced audio (differential) connections provide better analog audio quality over longer

cable runs. Most professional quality VTRs and audio equipment have XLR style connectors

for analog audio. Analog audio signals are converted internally to 24-bit digital.

Analog 2 Channel Unbalanced Audio (KL-box only)

On the KL-box are two analog output connectors, one for each channel. These connectors are

RCA-style phono jacks.

RS422 Machine Control

A female DB9 connector on the breakout cable provides connection for VTRs, camcorders,

disk media servers, and other devices using RS422 SMPTE (Sony) protocol. This connector is

also present on the optional KL-box. (Connector pinout is listed in Appendix A: Specifications.)

Analog Monitor Out (Component/Composite HD/SD)

Both the standard I/O cable and the optional KL-Box feature two groups of 3 BNC connectors

(each) for input and output of component, composite and Y/C functions. The signals are

labelled on both the cable and KL-Box connectors.

Component video signals are generally higher quality than composite, but not as high quality

as serial digital (SDI).

A Note About RGB—Although RGB is used less in today’s video systems, KONA LHe Plus

supports it. However, because the KONA LHe Plus (and SMPTE SDI) native format is

YPbPr, AJA recommends the use of YPbPr whenever possible for analog monitoring.

Although component video monitors often have RGB inputs, it’s better to use YPbPr

when the monitor supports it. The YPbPr format provides “headroom” for “superwhite”

and “superblack”—and these video levels will be clipped when transcoding to RGB. Also,

the RGB/YPbPr transcoding involves a level translation that results in mathematical

round-off error. RGB can be configured in the AJA Control Panel.

A Note About YPbPr—Component Video, or YPbPr, has been given several names over

time. YUV, Y/R-Y/B-Y, and YCbCr, are just some examples. Although these various formats
