We realize that you can’t
wait to hook up your new
Mackie Designs HRS120
High Resolution Powered
Subwoofer and try it out.
Nevertheless, please take the time to read this
page NOW, and the rest can wait until you’re
good and ready.
The HRS120 has its own built-in power am-
plifier. You should turn the
INPUT SENSITIVITY
control on the back of the cabinet down
(fully counterclockwise) before turning on the
HRS120 for the first time. Also be sure to set
the power switch
on the rear panel off
(down). This will prevent you from accidentally
connecting a hot signal source to the subwoofer
and getting a rude surprise.
There are a number of other settings you
can make on the back of the HRS120, and you
can read about them later on in this manual so
you really know what they do. For now, just
leave all the switches out, and the
CROSS-
OVER
controls set to the center position (
80Hz
).
For stereo applications:
1. Connect the left and right line-level signal
from your mixer, preamp, or other signal
source to the
LEFT
and
RIGHT IN
jacks
on the HRS120 (XLR or RCA).
2. Connect the
LEFT
and
RIGHT OUT
jacks on the HRS120 (XLR or RCA) to the
inputs of the left and right main powered
speakers (or to the inputs of the amplifiers
powering the left and right main speakers).
3. Connect the supplied AC power cord to the
IEC socket
on the back of the
subwoofer. Plug the other end into an AC
outlet properly configured with the correct
voltage for your particular model.
For surround sound applications:
1. Connect the LFE (Low-Frequency Effects)
or subwoofer line-level signal from your
mixer, preamp, or other signal source to the
LEFT (MONO) IN
jack on the HRS120
(XLR or RCA).
2. Set the
FILTER BYPASS
switch to the
FULL RANGE
position (pushed in).
3. Connect the supplied AC power cord to the
IEC socket
on the back of the
subwoofer. Plug the other end into an AC
outlet properly configured with the correct
voltage for your particular model.
