SDA Non-Common Ground Amplifier Interface

Free to a good home, just cover my shipping.... cut in half with plenty of length to patch back together. This was needed for me to remove it from my wall. Toes are not included, so I know Russ and Tom won’t be interested...

    I have the exact same one just like to know its purpose? I was powering a pair of SDA 2Bs with two Adcom GFA 555s bridged/mono. Does bridged make this a non-common ground set up?
    Thanks

    Yes , 2 monos make it non-common ground.
