# isInputGainSettable

A Boolean value that indicates whether you can set the input gain.

var isInputGainSettable: Bool { get }
```

## Return Value

Returns <doc://com.apple.documentation/documentation/Swift/true> if the device allows input gain to be changed, otherwise <doc://com.apple.documentation/documentation/Swift/false>.

## Discussion
