Nx1 Mixer (Linear)


Click here to return to the Mixers/Splitters page
There are three versions of 'NX1 Mixer' algorithm.

  1. 2×1 (No Slew)
  2. 3×1 (HW Signals)
  3. 4×1 (No Slew)


2x1 (No Slew)

The 2×1 Mixer has 2 input channels and 1 output channel. 2×1 mixers mixes two input channels to one output channel. Each input mix level can be independently adjusted. There are two combo boxes for setting the gain, one combo box for one input pin. To set the gain, click on the combo box and enter the value in the range of -128.0 to 127.999.

Input Pins

NameFormat [int/dec] - [control/audio]Function Description
Pin 0*: Decimal - audio Input signal
Pin 1*: Decimal - audio Input signal
Note : *Indicated for 2×1 Mixer. Input pins will increase by N


Output Pins

NameFormat [int/dec] - [control/audio]Function Description
Pin 2: Decimal - audio Mix of input signals to output channel

3x1 (HW Slew)

The 3×1 Mixer has 3 input channels and 1 output channel. 3×1 mixers,mixes three input channels to one output channel. Each input mix level can be independently adjusted. There are three combo boxes for setting the gain, one combo box for one input pin. To set the gain, click on the combo box and enter the value in the range of -128.0 to 127.999. The gain values are slewed to reduce audio clicks. Slewing options can be selected from the context menu.


Input Pins

4x1 (No Slew)

The 4×1 Mixer has 4 input channels and 1 output channel. 4×1 mixers mixes four input channels to one output channel. Each input mix level can be independently adjusted. There are four combo boxes for setting the gain, one combo box for each input pin. To set the gain, click on the combo box and enter the value in the range of -128.0 to 127.999.
