AJA Ki Pro (Ultra 12G / Ultra Plus / GO / Rack) troubleshooting

Common Ki Pro (Ultra 12G / Ultra Plus / GO / Rack) errors & problems

What techs run into most, and what's usually behind it. The step-by-step fix for your exact unit is in Ask Roadie.

• Ki Pro GO2: visible glitch at the cut between clips in back-to-back playback

  Likely cause: The decoder must reconfigure when the codec changes, which cannot be hidden in a seamless cut.

• How do I update firmware safely?

  Likely cause: Updating mid-record or without a reset can corrupt config or brick the flash; the refresh step avoids a false "update failed" scare when the browser session simply drops.

• Ki Pro GO vs GO2 media and codecs

  Likely cause: The approved list is the tested set for sustained 4-channel writes; the list was revised in July 2026, so checking a drive against the old v5.1r5 list can give a wrong answer.

• What is the current firmware for each Ki Pro? (2026)

  Likely cause: Each Ki Pro model has its own firmware track; loading the wrong model image or an old build is a common self-inflicted failure.

• Ki Pro GO/GO2 shows a B-frames warning when recording 10-bit 4:2:2

  Likely cause: The 10-bit 4:2:2 encoder profiles do not support more B-frames; the unit overrides the setting rather than refusing to record.

• Which PAK media do I need for multi-channel ProRes?

  Likely cause: Multi-channel recording multiplies the write bandwidth, so slower/older PAK revisions cannot keep up; picking the right file system avoids a re-copy step in post.

  Step-by-step fixGet the fix →

• Dropped-frames warning during record

  Likely cause: The recorder streams at a fixed data rate; if the drive cannot sustain write speed (fragmentation/directory errors) it drops frames.

• Machine control / deck control from a switcher or editor

  Likely cause: RS-422 Sony 9-pin is the broadcast standard editors/switchers speak; DATA-LAN mode repurposes the Ethernet port for file transfer instead of live control.

  Step-by-step fixGet the fix →

• Media will not mount / unit hangs on boot with media inserted

  Likely cause: The Ki Pro tries to mount inserted media during boot; a corrupt directory can hang that process.

  Step-by-step fixGet the fix →

• Source is not genlocked / no house reference available

  Likely cause: Frame sync buffers and re-times an off-speed input so it records cleanly without a shared clock; the looping ref input lets the unit lock to house sync when one exists.

• Analog / AES audio wiring (no sound or wrong channels)

  Likely cause: Several DB-25 audio pinouts exist; a non-TASCAM loom silently swaps or kills channels.

  Step-by-step fixGet the fix →

• Media won't record / not recognized

  Likely cause: The Ki Pro writes to its own file-system layout; computer-formatted or slow media fails its qualification checks.
