- INPUT LEVEL CONTROL: Adjusts the input sensitivity to match the source unit's output.
- BASS Control: Adjusts the level of the reconstructed bass output.
- SUBSONIC Control: Sets the low-frequency cut-off point to protect subwoofers from ultra-low frequencies.
3.2 Rear/Side Panel Connections
- GROUND ISOLATION Switch: Used to eliminate ground loop noise. Select between GND (grounded), ISO (isolated), or 200 (200 Ohm isolation).
- OUTPUT: RCA outputs for connecting to an amplifier.
- INPUT: RCA inputs for connecting to the source unit.
- REMOTE Port: Connects to the external parametric bass control remote.
- Power Terminals (12V, REMOTE IN, GND): Connections for power, remote turn-on, and ground.
4. Setup and Installation
Proper installation is crucial for optimal performance. If you are unsure about any steps, consult a professional installer.
4.1 Mounting
Mount the BX-22i securely in a dry location, away from excessive heat or moisture. Ensure adequate ventilation around the unit.
4.2 Wiring Connections
- Ground Connection (GND): Connect the GND terminal to a clean, chassis ground point in your vehicle. Ensure a solid, low-resistance connection.
- 12V Power Connection (12V): Connect the 12V terminal directly to the positive terminal of your vehicle's battery using a fused power cable. The fuse should be located within 18 inches of the battery.
- Remote Turn-On Connection (REMOTE IN): Connect the REMOTE IN terminal to the remote turn-on output of your head unit or another switched 12V source. This will turn the BX-22i on and off with your audio system.
- Audio Input (INPUT): Connect the RCA outputs from your head unit or signal processor to the INPUT RCAs on the BX-22i.
- Audio Output (OUTPUT): Connect the OUTPUT RCAs of the BX-22i to the RCA inputs of your amplifier.
- Remote Bass Control: Connect the provided remote bass control unit to the REMOTE port on the BX-22i using the supplied cable.
5. Operation
Once installed, adjust the controls for optimal bass performance.
5.1 Initial Power-Up
Turn on your audio system. The POWER LED on the BX-22i should illuminate, indicating it is receiving power.
5.2 Adjusting Input Level
Start with the INPUT LEVEL CONTROL set to its minimum position. Play a familiar piece of music. Slowly increase the INPUT LEVEL CONTROL until the bass sounds clear and powerful without distortion. If distortion occurs, reduce the level slightly.
5.3 Adjusting Bass Output
Use the BASS control to fine-tune the desired amount of bass reconstruction. Adjust this to your personal preference, ensuring the bass remains tight and defined.
5.4 Setting Subsonic Filter
The SUBSONIC control helps protect your subwoofers by filtering out frequencies below their usable range. Set this control to a frequency just below your subwoofer's lowest effective frequency. Common settings are between 25Hz and 40Hz. Refer to your subwoofer's specifications for guidance.
5.5 Ground Isolation Switch
If you experience alternator whine or other ground loop noise, try adjusting the GROUND ISOLATION switch. Start with 'GND', then try 'ISO', and finally '200' to see which setting eliminates the noise most effectively.
5.6 Remote Bass Control
The remote bass control allows for convenient adjustment of the bass level from your listening position. Use this to make real-time adjustments to the bass output.
6. Maintenance
The Soundstream BX-22i requires minimal maintenance to ensure long-lasting performance.
- Cleaning: Use a soft, dry cloth to wipe the exterior of the unit. Do not use harsh chemicals or abrasive cleaners.
