This switch reverses the polarity of the sig-
nal going to the subwoofer amplifier by 180º. It
has no effect on the signal at the
LEFT
and
RIGHT OUT
or the
MASTER OUT
.
There is no right or wrong setting for this
switch. Listen to the overall blend of the
subwoofer with the rest of the system, and select
the switch position that gives you the best sound.
LEFT AND RIGHT INPUTS
Balanced XLR female and unbalanced RCA
female connectors are provided for the left and
right inputs. Connect the full-range line-level
signal from the mixer or preamplifier to one of
these input jacks.
The connectors are wired as follows (per
the AES/IEC standard):
XLR RCA
Hot (+) Pin 2 Tip
Cold (–) Pin 3 —
Shield (Ground) Pin 1 Shield
If connecting a single subwoofer or LFE out-
put to the HRS120, use the
LEFT (MONO)
input with the
FILTER BYPASS
switch pushed in.
LEFT AND RIGHT OUTPUTS
Balanced XLR male and unbalanced RCA fe-
male connectors are provided for the line-level
left and right high-pass outputs. Connect these
to the inputs of the main speakers (if they are
powered speakers) or to the inputs of the am-
plifier powering the main speakers.
The signal at the left and right outputs is
post-crossover. The low-pass output from the
crossover goes to the internal power amplifier
in the HRS120, while the high-pass output goes
to these output jacks.
