Hi,
Recently baught a turntable. Im looking in to connecting a KAB subsonic rumbel filter, however this has to be connected after the preamp.
On the backplate on the Marantz 2252B there are four phono plugs for preamp out and amp inn, they are not connected - I red that they are connected internally.
How to intercept ? Is there an internal physical switch, or will the unit itself switch when external equipment is connected/intercepted ?
This preamp out, is it only for the phono inputs, or also fed from the radio, the aux etc ?
