FAQ
My audio is intermittent or drops out completely with edit to tape. What can I do?
The KONA LS monitoring playback looks choppy when capturing VHS sources. Is its capture quality okay?
Can I input a phantom-powered audio source into the KL Box or Kona LS? (Some professional audio sources supply 48 Volts at the connector, usually referred to as "phantom power".)
I get audio out of KONA with FCP canvas playback, but not with FCP viewer playback. Why?
How do I configure FInal Cut's Motion JPEG-A Codec?
How can I test RAID performance?
Sleep settings and Energy Saver (System Preferences)—how should it be set?
If I ever have to, can I "un-install" my KONA LS drivers?

Q: My audio is intermittent or drops out completely with edit to tape. What can I do?
A: Go to FCP Audio Video Settings -> Device Control Presets (tab). Click on <edit> (edit the current Io/Kona device control preset). Ensure the number of audio channels listed in "Audio Mapping" matches the number of audio channels of the sequence.
Q: The KONA LS monitoring playback looks choppy when capturing VHS sources. Is its capture quality okay?
A: KONA LS is capturing the VHS video properly with the help of its internal TBC, however the monitoring output shown during the capture doesn't reflect this. Instead it's showing the typical poor sync characteristic of VHS. Final Cut's canvas — the capture window — better reflects what is happening (athough at a lower framerate). When you playback the video after capture you'll see it was captured correctly. An unstable source like VHS will also appear poorly while monitoring when the KONA LS is set to "Input Passthrough".

Why the difference? During capture, KONA LS output is set to input passthrough. This means the video output is connected directly to the live video input—so if the live source has unstable sync so will the output from KONA. The reason captures are okay and the canvas display looks fine is that the input video is also routed to the framebuffers during capture. Video that gets written into the framebuffers on KONA is re-clocked, so sync issues from unstable sources are cleaned up and the video coming out of the framebuffer looks great. The captured video and the video that QuickTime displays in the canvas is pulled from the framebuffers and thats why these are fine.
Q: Can I input a phantom-powered audio source into the KL Box or Kona LS? (Some professional audio sources supply 48 Volts at the connector, usually referred to as "phantom power".)
A: No, applying phantom-powered audio sources can cause permanent damage to the audio circuits.
Q: I get audio out of KONA with FCP canvas playback, but not with FCP viewer playback. Why?
A: Go to the FCP sequence, control-click below the a1/a2 source markers, and select -> RESET PANEL.
Q: How do I configure FInal Cut's Motion JPEG-A Codec?
A: Read the KONA and Io Motion JPEG-A FAQ PDF.
Q: How can I test RAID performance?
A: Here's how to test your RAID with a real clip:

1) Set up your project with a KONA LS easy setup (type <control><q> for easy setup menu; make sure the "show all checkbox" is checked).

2) Create a new sequence (<apple> <n>). A new sequence will appear in the FCP browser.

3) In the FCP browser, double-click on the sequence; the new sequence will appear in the FCP timeline window.

4) Click on the Effects (tab) in the FCP browser.

5) Go to the Video Generators folder, and drag the appropriate Bars and Tone effect onto the new sequence.

6) Go to the Video Filters -> Video folder and drag the Timecode Generator Effect onto the video track of the new sequence (burned in timecode).

7) From the FCP menu bar, go to FILE -> EXPORT -> QUICKTIME MOVIE.

8) Give it a name and make sure the rendered clip is stored on the RAID.

9) From the FCP menu bar, go to FILE -> IMPORT, and select the clip that you exported in step 8.

10) Create a new sequence and drag the bars and tone clip onto the new sequence.

11) Hold Down the <shift><option><command> keys; From the FCP menu bar, go to TOOLS -> INTERNAL TOOLS, and select the Playback Meter. The playback meter monitors the RAID performance during playback. One for Audio, one for Video and two for Processing. The Playback meter should remain GREEN (center to right) for all the components it monitors during playback. If any of the performance bars goes to the left, the color will change to yellow or red which signifies that the RAID storage is not keeping up with playback.

12) Play the clip and monitor RAID performance with the Playback Meter.
Q: Sleep settings and Energy Saver (System Preferences)—how should it be set?
A: We recommend you set the Energy Saver "Sleep" setting to "Never" for optimum operation.
Q: If I ever have to, can I "un-install" my KONA LS drivers?
A: Yes, the KONA LS Installer automatically places an application called "Kona Uninstaller" in the "/Applications/Kona Utilities" folder on your PowerMac. Running the Uninstaller will result in removal of all the KONA LS driver software.
Recommended KONA LS System: Macintosh dual processor G5, and a Fibre Channel or SCSI external RAID for uncompressed SD storage.

Minimum KONA LSe System: Power Mac G5 (dual) PCI-Express, 2GHz with 1GB or more RAM. Ensure your Macintosh has a PCI-Express slot for compatibility.

Recommended KONA LSe System: Power Mac G5 PCI-Express (dual) 2.3 GHz or, for best performance a Quad 2.5GHz with 1GB or more RAM.
