Check the complete rear label. Standard GALAXY 816 and GALAXY 816-AES3 have different physical outputs. The standard model’s analog XLR outputs feed powered loudspeakers or amplifier inputs; they do not power passive cabinets.
Connections and required equipment
Analog or AES3 reaches the selected input; AVB audio uses the network ports. Compass controls input selection, matrix routing, processing and mutes. Ethernet control visibility alone does not establish a compatible network audio stream.
Prepare the system
- Save the working configuration; identify each output’s loudspeaker/zone and intended source.
- Confirm analog/AES3/AVB selection and clock status, then verify the matrix route at protected output level.
- Rehearse each zone separately; measure alignment before editing delay, polarity or Product Integration.
Questions and troubleshooting
Case: Compass sees the unit, but network audio is silent.
Separate controller connectivity from audio transport.
- Confirm the source actually provides a supported AVB/Milan stream and the network supports the required timing; Dante is not a directly interchangeable stream.
- Check subscription, input selection, AVB sync and Audio clock indications against the installed firmware guide.
- If controller activity is present without audio-clock/stream validity, the control connection has not verified audio delivery. After the documented correction, check input, output and the actual destination at controlled level; persistent sync/subscription errors require network and firmware details for Meyer Sound support.
Case: analog input B stopped after enabling AES3 on A.
The physical inputs form documented pairs.
- AES3 connects at A, C, E, G; the analog companion B, D, F, H is disabled when its pair uses AES mode.
- Choose the intended AES3 left/right channels in Compass or restore the planned analog pair with destinations protected.
- If restoring the planned input mode returns the expected channel meter, the paired-input selection was relevant; verify both intended channels and their destinations. If a known-good compatible signal still fails, record physical port, format and Compass selection for support rather than swapping modes repeatedly.
Case: input meters move, but one fill zone is silent.
Follow the route instead of adding input gain.
- Inspect the selected Summing Matrix crosspoint, gain, input/output mutes and actual output cable.
- If timing is wrong, record input, crosspoint and output delays separately; their contributions can accumulate.
- If input meters but the output does not, compare the matrix and mutes; if output is present, continue through cable and downstream input. Verify the same reference in the affected zone after correction; unresolved timing needs measured alignment by the system engineer, not a copied delay.
Choose the next check
| Observation | Next check | What to record |
|---|---|---|
| Network silence | Stream, subscription and clocks | Source, firmware, LEDs |
| Analog pair disappears | AES3 pair selection | Port and source format |
| Zone silent or late | Matrix, mutes, cable, delay blocks | Output map and snapshot |
Precautions
- Protect loudspeaker destinations before recalls, routing or level-range changes.
- Do not copy another system’s EQ, polarity or alignment values; use the exact loudspeaker documentation and measurements.
- Use the specified grounded mains connection and connector procedure; refer internal faults to qualified service.
