Controlling Multiple Devices
The Switch Gizmo features two electrically isolated switching jacks,
which makes it safe to connect each jack to a different device. When
connected this way, the 1 and 2 buttons control the first device and
the 3 and 4 buttons control the second device.
Even though it is possible to split the 1/2 or 3/4 jacks into two mono
ΒΌ-inch plugs using an insert cable and connect those plugs to two
different devices, this is not a recommended configuration.
Connecting two different devices to the same switching jack can
cause ground loops or even cause damage to your devices.
