I just thought I'd post this pic,...
of the 133 back panel. You see, there's a dbx control connector, and I'd assumed that this was specific to the DX-2d. No other dbx unit that I know of had the "control cable" connection, 'cept the Tascam DX-Series of dbx units. Beyond that, I plead my ignorance.
So, Herm, you got the dbx unit and have not tried it for about 3 years? Heh,... sounds like me.
GFM, I appreciate your effort to answer questions and your near-perfect track record. I'm wrong, & I apologize, etc, w/edit above.
I'd still get the DX-2D for hookup to the 133, and may very well do so, at some future time, as yet TBD.
I'm not familiar with dbx units, as well as some other folks.
cjacek, Good luck & Thanx.
