Click here to return to the Mixers/Splitters page
There are three versions of 'NX1 Mixer' algorithm.
- 2×1 (No Slew)
- 3×1 (HW Signals)
- 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.

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.
