Hardware Channels (Phantom Power)
A HwChannel represents a hardware input on the mixer. It can be used to control input gain and phantom power.
On the Ui24R, hardware inputs can be patched to different channels. This is why a hardware channel is not always the same as an input.
This distinction is also visible in the original protocol of the mixer as well as in the UI (Phantom Power/Gain are on another page than the input faders).
For Ui16 and Ui12, those hardware settings are part of the input channels internally.
To keep the library surface clean, this library considers the mixer model in the background and offers all options through the HwChannel class.
First, get a HwChannel by calling conn.hw(inputNumber), e.g. conn.hw(1) for the first input.
Phantom Power
Call on HwChannel | Description |
|---|---|
phantom$ | Get phantom power status (0 or 1) |
phantomOn() | Switch ON phantom power |
phantomOff() | Switch OFF phantom power |
togglePhantom() | Toggle phantom power status |
setPhantom(value) | Set phantom power status (0 or 1) |
Gain
Call on HwChannel | Description |
|---|---|
gain$ | Linear gain level of the channel (between 0 and 1) |
gainDB$ | dB gain level of the channel (between -6 and 57) |
setGain(value) | Set gain (between 0 and 1) |
setGainDB(dbValue) | Set gain in dB (between -6 and 57) |
changeGainDB(offsetDB) | Change gain relatively by adding a given value (in dB) |
Please note that the value conversion for gain dB values in the original Web UI is not exact.
Values emitted by gain$ may differ from the values visible in the UI.
