Frequently Asked Questions - PRIMUS PS212W INFINITY
How do I connect my PRIMUS PS212W subwoofer to my receiver?
Use a single RCA cable from the subwoofer output on your receiver to the Line Level LFE input. Alternatively, use speaker wire from your receiver's speaker terminals to the subwoofer's speaker-level inputs if your receiver lacks a dedicated sub output.
What is the best crossover setting for music?
Set the crossover to around 80 Hz. This blends well with most speakers. Adjust based on your main speakers' low-frequency capability.
Why does my subwoofer not produce sound?
Check that the power cord is connected and the subwoofer is turned on. Ensure the audio source is sending a signal. Confirm the volume and crossover are set appropriately. Also, verify the phase switch is in the correct position (try both 0° and 180°).
Can I place the subwoofer in a corner?
Yes, corner placement can increase bass output due to boundary reinforcement. However, it may cause boomy or uneven bass. Experiment with placement for best room integration.
How do I clean the subwoofer?
Unplug the subwoofer. Use a soft, dry cloth to gently wipe the cabinet and grille. Do not use any liquids or cleaning agents as they may damage the finish.
What is the phase switch for?
The phase switch (0°/180°) adjusts the timing of the subwoofer's output relative to your main speakers. Set it to the position that produces the strongest, most articulate bass at your listening position.
Is the subwoofer magnetically shielded?
No, the PRIMUS PS212W is not magnetically shielded. Keep it at least 2 feet away from CRT monitors or magnetic media to avoid interference.
What are the dimensions of the subwoofer?
The subwoofer measures approximately 14.5 inches wide, 16.5 inches high, and 16 inches deep (368 x 419 x 406 mm). Ensure adequate ventilation space around the amplifier.
Can I replace the driver myself?
Yes, the driver is replaceable. Order a genuine Infinity replacement driver. Remove the front grille, unscrew the driver, and disconnect the wires. Reassemble in reverse. Ensure proper polarity.
Does the subwoofer have a standby mode?
Yes, the subwoofer features auto-on/off. It will automatically power on when it detects an audio signal and switch to standby after a period of inactivity to save energy.
