Damn I'm old... Can't figure out the tape loop on a Bryston SP3


I haven't used a tape loop since the 80's..

I just received the B&W Bass Alignment Filter for my 802 s3's and I was trying to put it in the tape loop of my Bryston SP3 but for the life of me I can't figure out how to "enable" the tape loop function..  I run balanced from pre to amp so I would really like to use the unbalanced tape loop.  Also there I would be able to insert and remove the BAF from the path.

SP3 tape output to input of BAF, BAF output to SP3 input...  Physical is simple, but enabling it not so much.  SP3 manual mentions the tape loop but not how to engage it.

Weekend, Bryston is closed so posting here.

Tape (or processor) Loop, you go out to your deck or processor, and back to Tape IN. On older Preamps, there is a 'Monitor' or some similarly named switch that selects the tape loop input (doesn't matter what your source selector is using, it cuts to the tape input automatically).

this unit?

Looking at the rear jacks, there are two tape loops, one analog and one digital. It has to be selectable, and other settings are involved to get to 2 channel, etc.

here's your manual, perhaps someone here understands these modern devices, not me.
