Model and application
- Analog inputs
- 32
- Analog outputs
- 16
- Digital outputs
- 8 AES/EBU
- Dante
- 32 transmit / 26 receive
- Power
- Dual A/B supplies
Confirm Rio3224-D3, not D2 or Rio1608-D3. The console and control software must explicitly support D3. This rack supplies I/O and preamps; it does not replace the console’s mix buses.
Connections and required equipment
Microphone → analog input → Dante transmit → console subscription/input patch → mix bus → console Dante transmit → rack receive/output. Keep Dante PRIMARY/SECONDARY and the separate control network identified; a network socket is not an analog audio input.
Prepare the system
- Save the show and record compatible firmware, UNIT ID, startup mode and port mode.
- Follow the approved Dante topology and check link, sample rate and clock status before patching.
- With destinations protected, check one known microphone and one intended output, including mute and shared preamp ownership.
Questions and troubleshooting
Case: the console sees the rack, but the microphone is silent.
Discovery and HA control do not confirm the entire audio path.
- Compare rack input indication, Dante subscription and console input patch for the same source.
- Read the exact mute/status message. REFRESH with MUTE may be waiting for supported HA synchronization; restore that control path rather than forcing an unmuted startup.
- If rack input meters but the console does not, compare the subscription/patch; if a startup mute is indicated, resolve the documented synchronization condition first. Verify one agreed microphone through channel, bus and destination. Persistent status or sync errors require exact versions/messages for Yamaha support.
Case: the console channel works, but the stage output is silent.
Trace the return direction independently.
- Check mix-bus output assignment and console transmit to the intended rack receive channel.
- Compare rack output mute, destination/cable and local headphone monitoring; do not treat headphones as proof the physical output reaches the speaker.
- If the bus meters but the rack receive/output does not, the return route is the next check; if the rack output is present, continue to the destination. Verify the actual stage output at protected level; unresolved loss needs the full transmit/receive/output map for the system technician.
Case: a warning appears after changing the network.
Record the full message and indicator pattern before changing settings.
- Distinguish clock/rate, gigabit link, version mismatch and PRIMARY/SECONDARY warnings using the D3 status table.
- Compare the planned topology and compatible versions; schedule disruptive corrections outside the show, preserving the working configuration.
- A disappearing warning alone does not verify the audio route. After the documented correction, check status and repeat the same source/destination test. If it recurs, preserve the message and topology for Yamaha/network support instead of changing several settings together.
Choose the next check
| Observation | Next check | What to record |
|---|---|---|
| Remote input silent | Startup status plus input patch | Exact message and channel |
| Stage return silent | Console bus to rack output | Transmit/receive/output map |
| Network warning | Message-specific clock/link/version check | Topology and firmware |
Precautions
- Coordinate phantom power and shared preamp gain with every connected operator.
- Do not bridge redundant networks or change SEC.PORT mode while carrying a show.
- Dual supplies require a documented power plan; two plugs alone do not prove independent redundancy.
