How a crossover is used
The Sound Storm Laboratories SX210
is a high-fidelity signal processor that
allows you to divide a stereo audio
input signal into two frequency ranges:
a highpass output and a subwoofer
output.
Both outputs are stereo. For use in
systems where there is a single mono
subwoofer, the SX210 features a circuit
which merges the left and right sub-
woofer channels so that the signal
presented to the left and right subwoof-
er outputs is mono.
For improved time alignment, the sub-
woofer channel also features a selector
for switching the subwoofer output
signal phase.
This crossover intended for use in a
car audio system which includes am-
plifiers in the signal path after the head
unit.

Installation
Choose a mounting location where the
unit will not distract or otherwise
interfere with the driver’s ability to
control the vehicle.
Use only the installation parts and
hardware provided with the unit to
ensure proper installation. Using other
parts can cause malfunction and
possible damage to your crossover.
Avoid installing the unit in a location
which is subject to high temperatures,
direct sunlight, hot air from such
sources as heaters or exhaust lines,
or where it will be subject to contact
with dust, dirt, moisture or excessive
vibration.
Making electrical and audio
connections
Using the screw terminals provided,
connect the following wires:
+12V:
Use a minimum 16GA wire and
connect it directly to the vehicle's (+)
battery terminal, with a inline 3A fuse
within 18 inches of the battery.
GND (Ground):
Use a minimum 16GA wire and
connect it to a clean, solid chassis
ground point as close to the crossover
as possible.
REM (Remote):
Use a minimum 16GA wire and
connect it to the Remote Turn-On lead
of your head unit.
Audio Cables:
Use high quality RCA cables. Make
connections as shown in the diagram
shown elsewhere in this manual.
Getting started
Before powering up your system:
1) recheck all connections
2) set all level controls to the minimum
positions
3) set all crossover controls and
switches to the desired positions.
Power up your system and set the
volume control on your head unit to a
moderate level (typically this is a level
where you can still have a normal
conversation and be heard over the
audio). You may need to further fine
tune the system to suit your taste.

FREQUENCY CONTROL
Use this to select the frequency range
sent to the subwoofer outputs. The
selected frequency is the highest
frequency which will be reproduced
by the subwoofer(s).
BASS BOOST CONTROL
This control allows you to increase the
level of the bass up to +12dB, centered
at 45Hz.
SUB STEREO/MONO SELECTOR
For systems where you need stereo
subwoofer outputs, choose STEREO.
All others choose MONO.
PHASE SELECTOR
Select the phase of the subwoofer
output channel(s) for best time alignment
and imaging.
SUBWOOFER OUTPUT LEVEL
Use to independently increase or
decrease output gain.
