Frequently Asked Questions - HTPS-400 JBL
How do I connect the HTPS-400 subwoofer to my AV receiver?
Use the LFE (RCA) input on the subwoofer. Connect an RCA cable from the subwoofer output on your AV receiver to this input.
What is the purpose of the phase switch?
The phase switch (0/180°) adjusts the subwoofer's timing relative to the other speakers. Set it to the position that gives the loudest and most balanced bass at your listening position.
Why is my subwoofer not turning on automatically?
Check that the Auto Standby feature is enabled. If the subwoofer does not receive an audio signal for several minutes, it goes into standby. Ensure the AV receiver is sending a low-level signal.
Can I place the subwoofer in a cabinet or enclosed space?
It is not recommended. The subwoofer needs adequate ventilation to prevent overheating. Place it in an open area with at least a few inches of clearance around the amplifier panel.
What is the recommended crossover frequency setting?
Start with the crossover dial set to 80 Hz (THX standard). Adjust based on your main speakers' capabilities. Higher for smaller speakers, lower for larger ones.
How do I clean the subwoofer?
Unplug the unit and use a soft, dry cloth to wipe the exterior. Do not use any liquid cleaners or solvents, as they may damage the finish or components.
What should I do if the subwoofer produces a humming noise?
Hum can be caused by a ground loop. Try using a grounded outlet, check cable connections, or use a ground loop isolator. Ensure the subwoofer and receiver are on the same electrical circuit.
Does the HTPS-400 have a wireless connection?
No, the HTPS-400 requires a wired connection via RCA or speaker-level inputs. It does not support wireless subwoofer kits.
What type of driver does it use?
It uses a 10-inch (254 mm) cone driver with a rubber surround for accurate bass reproduction.
Is the subwoofer compatible with 220-240V systems?
The US model operates at 120 V ~ 60 Hz. For other voltages, check the label on the back. International models may vary; use a step-down transformer if necessary.
