Common QL5 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.
- Step-by-step fixGet the fix →
"Network Audio Module Failed. Please Restart the Console." error appears
Likely cause: The message is thrown when the on-board Dante module fails to hand off its settings to the console CPU at boot; a clean restart re-initialises the module.
- Step-by-step fixGet the fix →
Dante devices (R-series racks) lost audio or wrong channel count after a config change
Likely cause: Channel-count and topology changes alter the Dante flow map the console loaded at boot; the console only re-reads that map on restart, so audio routing goes stale until it is rebooted.

Dante patch to a computer / Dante Via will not mount on the QL5
Likely cause: The QL mount system only supports Yamaha-qualified Dante endpoints; software transmitters like Dante Via aren't in that list, but Dante Controller can still route their flows at the network level.

Display shows "UNLOCK" / clicks, pops or dropouts on digital audio
Likely cause: Digital devices must share one sample-rate reference; if the selected master clock is absent or at a different rate the console cannot lock, producing UNLOCK and audible artefacts.

Faders are misaligned, overshoot, or drift out of position
Likely cause: Fader friction changes over months of use and dust can enter the track, causing the motor to overshoot; calibration re-teaches the motor end-stops.

How do I update the QL5 firmware / what is the latest version?
Likely cause: V5.91 added support for Shure wireless frequency band G57 and for mounting/HA control of Rio3224-D3 & Rio1608-D3.
- Step-by-step fixGet the fix →
Input gain / output level seems inconsistent across channels
Likely cause: Analog head-amp and DAC stages can drift slightly over time; the gain-calibration routine re-aligns them so metering and level match across all channels.

Key QL5 specs for rack/power/rigging planning
Likely cause: Accurate footprint, weight and power figures let you spec the desk table/road case, power distro and cable runs correctly for a show.

Where is Dugan automixing and how many mics does it handle on the QL5?
Likely cause: The QL DSP hosts a licensed Dan Dugan auto-mix algorithm; it continuously redistributes gain so total open-mic gain stays constant, reducing feedback and ambient buildup without a hardware Dugan unit.
