Speaker-Level Inputs:
If your receiver
or amplifier does not have a line-level
subwoofer output, connect these binding
post terminals to the main (front) left and
right speaker terminals of your receiver or
amplifier. Remember to maintain polarity
by connecting the positive (+) terminal on the
receiver/amplifier to the positive (+) terminal
on the HKSUB 12 subwoofer, and the negative
(–) terminal on the receiver/amplifier to the
negative (–) terminal on the HKSUB 12
subwoofer.
™
Speaker-Level Outputs:
If you are
using the
Speaker-Level Inputs
¡
on
the HKSUB 12, connect these binding post
terminals to your front left and right speakers,
remembering to maintain polarity by con-
necting the positive (+) terminal on the
HKSUB 12 subwoofer to the positive (+)
terminal on the speaker, and the negative (–)
terminal on the HKSUB 12 subwoofer to the
negative (–) terminal on the speaker. If you
are not using the
Speaker-Level Inputs
¡
, connect your front left and right speakers
directly to your receiver or amplifier. See
pages 12 through 15 for further information
on speaker connections.
£
Line-Level Full-Range Inputs:
Connect
the full-range, unfiltered line-level subwoofer
output or preamp output(s) of your receiver or
amplifier to these inputs. If your receiver does
not have a separate subwoofer output, use a
Y-adapter (not supplied) to bridge the receiver’s
preamp output to the main amp input for that
channel, and connect the long end of the
adapter to the corresponding line-level input
on the HKSUB 12. If your receiver has only a
single subwoofer output, you may connect it
to either the left or right line-level input on the
HKSUB 12, and no Y-adapter is needed.
¢
Line-Level Subwoofer (SUB) Input:
Connect the filtered subwoofer output of a
receiver to this input. This input bypasses
the HKSUB 12’s internal crossover circuitry,
and should only be used with a filtered sig-
nal. If your receiver does not have a filtered
subwoofer output, you should use the
Line-
Level Full-Range Inputs
£
instead.
