Frequently Asked Questions - BassLink 4SC INFINITY
How do I connect the BassLink 4SC to my receiver?
You can connect using either the RCA line-level inputs or speaker-level inputs. Use a subwoofer cable from the receiver's subwoofer output to the RCA input on the subwoofer. For speaker-level, connect the receiver's speaker wires to the subwoofer's speaker-level input terminals.
Does the subwoofer automatically turn on?
Yes, the BassLink 4SC features an auto on/off function that detects an audio signal. It will turn on when a signal is present and turn off after a period of inactivity.
What is the crossover frequency and how do I adjust it?
The crossover is adjustable from 40 Hz to 120 Hz. Turn the crossover knob on the subwoofer to set the point where the subwoofer blends with your main speakers. A good starting point is 80 Hz.
What is the phase control for?
The phase control (0°/180°) helps align the subwoofer's output with your main speakers for smoother bass. Switch between settings to hear which gives the most cohesive sound at your listening position.
Can I use this subwoofer with a car audio system?
The BassLink 4SC is designed for home use with a standard AC power outlet. For car use, you would need a power inverter. However, Infinity offers car-specific subwoofers.
What size fuse does the subwoofer use?
The BassLink 4SC typically uses a 2.5A or 3A fuse. Always replace with the same type and rating to avoid damage.
How do I clean the subwoofer?
Unplug the subwoofer and wipe the exterior with a soft, dry cloth. Do not use any liquid cleaners or abrasive materials.
Why is my subwoofer making a humming noise?
A humming noise is often due to a ground loop. Ensure all components are plugged into the same power strip. Try using a ground loop isolator on the RCA cable.
Can I place the subwoofer on its side?
The subwoofer is designed to be placed upright. Placing it on its side may affect performance and stability. Always follow the manual's placement recommendations.
