Need an A/B switch on the Preamp, that has separate, volume control for the two different zones.
It sounds like you found a tape monitor, loop. The volume is set. You can lower the signal, with a passive preamp or something. It does not have volume control..and you'll only be able to lower the volume, with a passive.
Regards
