13 Introduction — Cable Connections
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.
RS-422 Machine Control
A female DE-9 connector on the LHi/LSe breakout cable provides connection for VTRs,
camcorders, disk media servers, and other devices using RS-422 SMPTE (Sony) protocol. This RS-
422 connector is also present on the optional KL-Box (connector pinout is listed in “Machine
Control Connector Pinout” on page 118).

Descriptions—
KONA 3 Cables and
K3-Box Connectors on the standard cable set are labelled for their function for easy installation and
maintenance. Connectors on the optional K3-Box (breakout box) are similarly labelled.
8-Channel Digital AES/EBU Audio Inputs and Outputs
When using the standard cables, XLR connections are provided for AES/EBU audio input/output.
Four female XLR connectors are provided for audio input and four for audio output. Each XLR
carries two channels. XLR connectors are labeled for input/output and channels.
The optional K3-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 breakout box are two analog output connectors, one for each channel. These connectors
are RCA-style phono jacks.
RS-422 Machine Control
A female DE-9 connector provides connection for VTRs, camcorders, disk media servers, and
other devices using RS-422 SMPTE (Sony) protocol. This connector is present on both the
general I/O cables and the optional K3-Box. (Connector pinout is listed in
“Machine Control
Connector Pinout” on page 118 .)
SDI Inputs and Outputs
On the KONA 3/3x card, 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.
KONA 3 has three video outputs altogether—two SDI outputs that are used for both High- and
Standard-definition (SD/HD-SDI), and one component analog output (discussed later). 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 and 8-channel 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
