Trouble Shooting
The USUB is designed to function trouble free. Most problems that may occur are due to simple issues. Please check
below for a list of simple fixes if you experience any issues.
Ensure that the Status LED is blue and the power switch is ON.
No Sound
1. Verify that audio is coming form the source selected. Select another source to test, or connect the source
directly to the subwoofer input bypassing any other equipment.
2. Ensure that any connected A/V equipment is turned ON and connected properly.
3. Check cable connections for damage, poor connection or shorts.
4. Ensure subwoofer volume is turned up to a reasonable level using the control on the back of the unit.
Interference or undesired noise coming from subwoofer:
1. Check all connections for damage, poor connection or shorts.
2. If the signal cable is installed inside of the wall, it may be running parallel to a high voltage cable. Test the
system by running a separate in room cable. If the issue is resolved, a new cable should be installed with the
proper clearance from high voltage.
3. Common sources of interference include Wi-Fi antennas and devices or cordless phones setup too close to the
subwoofers source.
Cleaning & Maintenance
The exterior of the subwoofer may be cleaned using a soft lint free cloth. If the subwoofer is moved often for cleaning or
relocation, check each time to ensure that connections are not damages or loose.
