Frequently Asked Questions - Reference SUB R12 INFINITY
How do I connect the Infinity Reference SUB R12 to my receiver?
Use a single RCA cable from your receiver's subwoofer output (LFE) to the subwoofer's LFE input. Alternatively, use line-level inputs if your receiver has pre-outs.
What is the ideal placement for the subwoofer?
Place the subwoofer in a corner or along a wall for maximum bass output. Avoid placing it in the center of the room. Experiment with placement to minimize standing waves.
How do I set the crossover frequency?
Start with the crossover set to 80 Hz if using with a receiver. Adjust between 50-150 Hz to blend seamlessly with your main speakers. For LFE connection, set the crossover to the highest setting (150 Hz) and let your receiver handle the crossover.
What does the phase switch do?
The phase switch (0° or 180°) helps align the subwoofer's output with your main speakers. If the bass sounds weak at the listening position, try flipping the phase switch.
Why is my subwoofer not turning on?
Ensure the power cord is connected and the subwoofer is plugged into a working outlet. The auto-standby feature may have turned it off if no signal is detected; play audio to activate it. Verify that the power switch is on.
How do I clean the subwoofer?
Unplug the subwoofer before cleaning. Use a soft, dry cloth to wipe the cabinet and grille. Do not use any liquids or cleaning agents, as they may damage the finish or internal components.
Can I use the subwoofer in a home theater system?
Yes, the Infinity Reference SUB R12 is ideal for home theater. Connect it to your AV receiver's LFE output for dedicated low-frequency effects.
What is the maximum power rating?
The subwoofer has a built-in amplifier rated at 300 Watts RMS and 600 Watts peak. It is designed to handle this power without distortion.
How do I adjust the volume level?
Use the volume knob on the back panel. Start with a low setting and gradually increase until the subwoofer blends with your speakers without overpowering them.
What type of cable should I use?
Use a standard RCA audio cable with a single male connector on each end. For optimal performance, use a shielded subwoofer cable to reduce interference.
