Sound Storm Laboratories SX210 2-Way Car Electronic Subwoofer Control

How a crossover is used

The Sound Storm Laboratories SX21 O 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 sub­woofer channels so that the signal presented to the left and right subwoof­er outputs is mono.
For improved time alignment, the sub­woofer channel also features a selector for switching the subwoofer output signal phase.
This crossover is intended for use in a car audio system which includes am­plifiers 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.

Controls and features

1. SUBWOOFER CROSSOVER 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).
2. BASS BOOST CONTROL
   This control allows you to increase the level of the bass up to + 12dB, centered at 45Hz.
3. SUB STEREO/MONO SELECTOR
   For systems where you need stereo subwoofer outputs, choose STEREO. All others choose MONO.
4. PHASE SELECTOR
   Select the phase of the subwoofer output channel(s) for best time alignment and imaging.
5. SUBWOOFER OUTPUT LEVEL
   Use to independently increase or decrease output gain.
6. LEFT and RIGHT AUDIO INPUTS
7. LEFT and RIGHT SUB OUTPUTS
8. LEFT and RIGHT HIGHPASS OUTPUTS
9. REMOTE SUBWOOFER LEVEL CONTROL JACK
10. FUSE
    Power Connections:
11. +12V
12. rEMOTE
13. GROUND
14. FRONT HIGH PASS CROSSOVER FREQUENCY CONTROL
    Sets the crossover frequency for the front (high pass) crossover.
15. POWER INDICATOR
16. HIGH PASS OUTPUT LEVEL
    Use to independently increase or decrease output gain for this channel.

Audio connections

Review the diagram below and connect the unit as shown.

Power connections

Please note that this crossover contains an internal ON/OFF switch, which is activated when the head unit is turned on. For this reason, in order to use this crossover, your head unit must have a remote turn on lead.

Troubleshooting

If you experience operation or performance problems with this product, compare your installation with the electrical wiring diagram on the previous page. If problems persist, read the following troubleshooting tips which may help eliminate the problems.
