Every zone has a Min Volume and a Max Volume setting, which together define the range its volume control operates over. This covers what they do and how to use them.
How They Work
Both settings are absolute volume levels. A level of 0 means the signal going out matches the signal coming in — unity gain. Each step is a 0.5 dB change, so a setting of 1 is +0.5 dB of gain, and -1 is -0.5 dB of loss. The defaults are 24 (+12.0 dB gain) for Max Volume and -120 (-60 dB loss) for Min Volume.
The zone's actual volume control runs from 0 to 100:
| Volume setting | What it does |
|---|---|
| 0 | Always fully muted, regardless of Min/Max Volume |
| 1 | Sets the level to whatever Min Volume is set to |
| 100 | Sets the level to whatever Max Volume is set to |
| 2–99 | A proportional point between Min and Max — e.g. 50 sits exactly halfway between them |
Using Max Volume
Max Volume is straightforward — it caps how loud a zone can go, regardless of what a user requests. Useful for limiting volume in specific zones.
Using Min Volume
Min Volume is more subtle. In a quiet room, you can turn the volume down and still hear audio at whisper levels — in that case, set Min Volume to a large negative value so the volume control can go correspondingly low.
Outdoor speakers are the opposite case. Background noise often means nothing changes once volume drops below 50% — half the control's range feels wasted, and holding the volume-down button between 1% and 49% can feel like the system isn't responding. Raising Min Volume until you can just start to hear something — often around 5% — gives you the full 1–100% range of useful control, with the sound fading out cleanly below that point rather than wasting half the range on inaudible levels.
