AMPLIFIER PANEL CONTROLS AND CONNECTIONS
AMPLIFIER PANEL CONTROLS AND CONNECTIONS
¡
Speaker-Level Inputs: If your receiver
or amplifier does not have a line-level
subwoofer output, connect these binding
post terminals to the main left and right
speaker terminals of your receiver or
amplifier. Remember to maintain polarity
by connecting the (+) terminal on the
receiver/amplifier to the (+) terminal on the
HKSUB 12 subwoofer, and the (–) terminal on
the receiver/ amplifier to the (–) 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 (+) terminal on the HKSUB 12
subwoofer to the (+) terminal on the speak-
er, and the (–) terminal on the HKSUB 12
subwoofer to the (–) terminal on the speak-
er. If you are not using the
Speaker-Level
Inputs
¡
, connect your front left and
right speakers directly to your receiver
or amplifier. See pages 9 through 12 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,
