Crossfader Component

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.

Controls

The controls listed below are divided into sections to match the Control Panel sections.

Once you establish the initial settings for a component, you can save those settings, along with all the other component's settings, in a Snapshot.

Crossfader

Control	Function	Default/Range
Gain A and B (dB)	Displays the current gain value for each channel. During a crossfade operation, one value is increasing, the other decreasing.	Default for A = 0 Default for B = -120 Range = -120 to 0
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.	Default = 0 Range = 0 to 100
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.	Default = A on, B off

Control

Function

Default/Range

Gain A and B

(dB)

Displays the current gain value for each channel. During a crossfade operation, one value is increasing, the other decreasing.

Default for A = 0

Default for B = -120

Range = -120 to 0

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.

Default = 0

Range = 0 to 100

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.

Default = A on, B off

Configure

Control	Function	Default/Range
Time (seconds)	The Time controls the length of time it takes the Crossfader to fade from one channel to the other.	Default = 1.00 Range = 0.01 to 100
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.	-3 dB constant power -6 dB constant gain

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.
