Crossfader
The Crossfader component allows you to fade between two input channels going to one output. You can specify a mono Crossfader, having two inputs and one output, a Stereo Crossfader, having four inputs and two outputs, or a Multi-channel Crossfader. The number of inputs is always double the number of outputs.
You manually trigger the fade from Input A to Input B, and back. You can control the time it takes to fade from one channel to another. All of the inputs and outputs (Mono, Stereo, and Multi-channel) on a single Crossfader component are controlled simultaneously.
Inputs and Outputs
Note: The number of signal pins is variable and set in the component's Type Property.
Input Pins
Input
Audio signal pins are represented by a (
) circle, and traditional wiring is represented by a thin black line.
By default, the Crossfader component is set to a Mono channel, which provides 2 inputs. Additionally, you can set the Properties to allow for Stereo, which gives you 4 inputs (Right and Left for each input); or you can choose Multi-Channel, which will allow you to choose between 2 and 256 inputs and outputs.
Output Pins
Output
Audio signal pins are represented by a () circle, and traditional wiring is represented by a thin black line.
By default, the Crossfader component is set to a Mono channel, which provides 1 output. Additionally, you can set the Properties to allow for Stereo, which gives you 2 outputs (Right and Left); or you can choose Multi-Channel, which will allow you to choose between 2 and 256 inputs and outputs.

Crossfader Properties
Channels
Type
Selects the range for the number of inputs.
Count
Only available if the Type Property is Set to Multi-Channel. Selects the number of inputs for Multi-Channel.
Controls
Crossfader
Gain A and B (dB)
Displays the current gain value for each channel. During a crossfade operation, one value is increasing, the other decreasing.
Position (percentage)
Displays the positional balance between Input A and Input B.
Zero percent (0%) the output is equal to Input A.
One hundred (100%) the output is equal to Input B.
Xfade to A and B
Radio style buttons that start the crossfade operation. If the Position reading is at 0%, the Xfade to A button is on, or true and Channel A is going to the output.
If the Position reading is at 100%, the Xfade to B button is on, or true and Channel B is going to the output.
You can click either button to start the crossfade operation.
Configure
Time (seconds)
The Time controls the length of time it takes the Crossfader to fade from one channel to the other.
Type
The Type control allows selection of the crossfade type: -6 dB constant gain or -3 dB constant power.
With -6 dB constant gain type selected, the Crossfader sums the input signals with a constant combined gain. The midpoint gain is -6dB. This setting is suited for correlated input signals but results in a 3 dB dip at the midpoint for uncorrelated signals.
With -3 dB constant power type selected, the Crossfader sums the input signals to a constant combined power. The midpoint gain is -3dB. This setting is suited for uncorrelated input signals and is the preferred one.

Troubleshooting
There are some components that are unique in their operation in the Emulate mode. Some of these components are the Audio Player, Crossfader, Gain Ramp, and Listen buttons. For more information, see Limitations.
