| The rear panel has XLR connectors for the input and the outputs. All connections are balanced (pin 2 positive) and transformer-isolated. |
| Pin 1 of the input is connected to the chassis ground. There is a screw next to the input connector that can be replaced with a ground terminal (supplied) if you prefer to use a separate ground wire, rather than supply ground through the input cable. |
| The output grounds (pin 1) are completely isolated from the input and from each other. Logically, this is like a reverb chamber; the outputs can be thought of as coming from a pair of microphones inside. There is no possibility of ground loops. |
