 Q111  Pan/Fade

Click Image for Large View 

Click here to see a large image
The Q111 Pan/Fade module can pan an input signal between two outputs, or fade an output signal between two inputs. For example: Pan mode would allow a single input signal to be routed to one of two different speakers. Fade mode allows an output to fade from one of two input signals. Both Pan and Fade modes allow both manual and voltage control.

Usage and Patch Tips

Pan Mode Basics
Input #2 is not used in Pan mode. Put an input signal into the Input #1 connector. The combination of the control voltage input and the Initial Control setting will determine how much of the input signal will be routed to each of the outputs. To pan a signal back and forth between the outputs, set the Initial Control to 0, and patch a +/-5volt sine wave from an oscillator to the Control Input connector.

Fade Mode Basics
Output #2 is not used in Fade mode. Put signals into both input connectors. The combination of the control voltage input and the Initial Control setting will determine how much of which input signal will be routed to the output. To fade a signal back and forth between the inputs, set the Initial Control to 0, and patch a +/-5volt sine wave from an oscillator to the Control Input connector.

Switching
By using a square wave as the control signal, a voltage controlled switch can be created.

Signal Polarity
In Pan mode (1 input, 2 outputs), Output #2 is inverted. In Fade mode (2 inputs, 1 output), Input #2 is inverted. This may or may not be an issue depending on your use. Use a Q125 signal processor to invert the signal back to its original polarity if needed.
