KONA LHe Plus Installation & Operation Guide — Understanding Typical

KONA LHe Plus

Audio

KONA LHe Plus supports two-channel 24-bit 48kHz AES audio via XLR connections, and

eight-channel embedded 24-bit 48kHz audio over the same single SDI connection as the

video. If you are using a digital deck—you’ll have the proper connections to the deck.

For analog audio, KONA LHe Plus provides two-channel balanced audio input and output.

If you purchase the optional KL-Box breakout box, you also get two-channel unbalanced

audio output (RCA jacks).

KONA LHe Plus also features AES input sample rate conversion; this feature eliminates the

requirement for audio source synchronization. Sample rate converters auto-lock to any

AES input, 32-96KHz, and then convert it to 24 bit 48KHz audio, perfectly locked to

internal KONA LHe Plus video. Sample rate conversion is done at very high quality (over

120db THD).

Software • KONA LHe Plus control panel for source selection and controlling KONA LHe Plus

within the overall MacOS environment (Macintosh Desktop, Input Pass through, and

more).

• AJA QuickTime™ drivers for tightly integrated hardware/software operation.

• Supports all popular standard definition formats: 8/10 bit uncompressed, JPEG,

DV25/50, and 3:2 pulldown for 24Hz support.

• Support for Apple Final Cut Pro 7™ (application software not included).

• Support for After Effects, Combustion, Motion, and Other Applications

(application software not included).

AJA’s KONA LHe Plus software and hardware were developed for use with Final Cut Pro 7

for powerful integrated video/audio capture, editing, and video production. With an

Apple Mac Pro, FCP 7, and KONA LHe Plus, you have an ideal high-quality cost-effective

system for standard definition, high definition, and analog video production workflows.

Software is supplied on CD, including the AJA Control Panel, drivers for the card itself, and

all files necessary for Final Cut Pro 7 and other application support (Final Cut Pro 7

software application not included).

Understanding Typical Workflows

KONA LHe Plus and Final Cut Pro 7 allow more workflow flexibility than ever before. Users

can independently select different formats for capture and storage media, while also

outputting to an array of analog and digital uncompressed formats—with all outputs

active simultaneously. Capture can range from analog, DV, or SD and HD digital

uncompressed. Media can be stored on disk as:

• offline quality at low bit rates

• on-line quality at moderate bit rates

• or with the highest quality as 8 or 10 bit uncompressed SD and HD

As quality and codecs improve, the lines between offline and online are blurring. For

example, with the Apple ProRes 422 codec, native HD editing in that codec is now

possible, providing very high quality results (true HD editing) at very low data rates.

Following are summaries of the most common codecs used in various workflows,

providing data rates and relative quality levels. Some workflows require a RAID array and

some will work using the host Apple computer's internal system drive (as noted where

supported).

PhotoJPEG Data rate: approximately 1-3 MB/second standard definition or high definition—

supported by internal system drive

Quality: Very Good
