What can be operated remotely with the ODR-1X?

You can switch the gain boost and on/off functions remotely. It is important to know that you use a switch that emits a short pulse. These are called momentary or unlatched. In other words, NOT a switch that holds the contact when you press it and cancels the contact when you press it a second time. If you only want to remotely control the boost function, a simple switch connected to the remote socket with a standard mono jack cable is sufficient.
For the double function, use a stereo jack cable (TRS) – or an insert cable if necessary.
Of course, a looper/switcher can also be helpful in such a case.
