It might not have internal bass management,but you can simply use the pre out connections.
Macintosh pre amps
I'm not used to connections other than AV/Receivers, but looking at McIntosh pre-amps, both Tube and SS, I can't see or figure out connections for subwoofers?? What am I missing? I looked at the C49 manual, there's not mention about subwoofer connections.
My question? Can you connect to McIntosh pre-amps subwoofers directly?
I can't believe that at that price levels there's no sub connections.
