Not sure I understand - I don't seem to have that problem. I always leave the transporter out at 100 and use the tact to control the volume that's fed back into the transporter. For what you suggest to happen the transporter would have to control the volume digital output of the tact. My setup

I ran my TP straight to power w/no pre for 2 years. Because I used balanced outputs, I needed to use an attenuator (Endler stepped was excellent) to control the gain. Worked very well, although I eventually added a really nice pre and it sounded even better. Anyway, yes, it is easy to switch to
