Joranalogue - Switch 4

Switch 4 is a great tool for live performers. The module can be used to quickly turn audio signals or control voltages on and off. Thanks to two types of switching channels, the routing can be changed in no time at all. On top of this, it is possible to use the circuit as a Switched Multiple. Three-way switches allow musicians to active channels momentarily or constantly. High-end components guarantee excellent sound quality. - Not a given, considering the low price.

Switch 4 can handle audio material as well as control voltages. The front panel is divided into two areas. At the bottom, there are four inputs that pass signals to four outputs. Switches for activating / deactivating the channels have been installed between the sockets. The inputs are normalized so that a signal can be sent to several outputs.

Two additional switching channels are located at the top of the front panel. Via knobs, users can select which of the four inputs mentioned before is connected. Subsequently, switches and outputs follow.

High-end components guarantee low noise and distortion. All channels are buffered. The switches feature a three-way design. If the user pushes a control element downwards, it will spring back to the middle position after releasing it. Upwards, it works like a toggle switch for activating channels constantly.

New in revision C:
Input A is now normalized to a voltage of +5 V as long as no cable is connected. Thus, Switch 4 is now able to generate gate signals on its own.
All outputs have impedance compensation in revision C to improve voltage accuracy.

New in revision D:
revD has a small improvement to avoid possible glitches when using the routing section.
