Connecting the subwoofer

In a traditional single subwoofer setup, connect the subwoofer to the left analog out on the TDAI-2170.

For a stereo subwoofer setup, or if you have a subwoofer which has stereo input, use both left and right

analog out.

Warning

: Do not connect the TDAI-2170 to a subwoofer with speaker terminal inputs if they are

grounded. The TDAI-2170 +/+ speaker output

terminals must never touch each other, likewise the

-/- speaker output terminals.
