Frequently Asked Questions - Entra Sub Two INFINITY
How do I connect my Infinity Entra Sub Two subwoofer to my amplifier?
Use the LFE line input for a home theater receiver, or the speaker level inputs for a stereo amplifier. For LFE, connect an RCA cable from the receiver's subwoofer output. For speaker level, connect wires from the amplifier's speaker terminals to the sub's high-level inputs.
Where is the best placement for a subwoofer?
Place it near a wall or corner for deeper bass, but avoid the exact center of the room to minimize standing waves. Move it around while playing bass-heavy music to find the optimum position for your space.
How do I set the crossover frequency?
Set the crossover on your receiver to around 80 Hz if available. If not, adjust the sub's crossover between 50 and 150 Hz to blend smoothly with your main speakers.
My subwoofer has no sound. What should I check?
Verify that the power is on, the volume is turned up, and all input cables are securely connected. Also try the phase switch in both positions to see if one delivers more bass output.
Can I use this subwoofer with a stereo system that has no LFE output?
Yes, use the speaker level inputs and connect them to the amplifier's speaker output terminals. The sub's internal crossover will filter out the high frequencies, letting it reproduce only bass.
What does the phase switch do?
The phase switch (0° or 180°) adjusts the timing of the sub's output relative to the main speakers. Choose the setting that gives the fullest and most balanced bass at your listening position.
How do I clean the subwoofer cabinet?
Use a soft dry cloth to gently dust the cabinet and grille. Do not use water, abrasive cleaners, or any solvents, as they could damage the finish.
Is the subwoofer safe to leave on all the time?
Yes, the sub features standby mode that activates when no audio signal is present, consuming less than 0.5W in standby. You can also switch it off manually for peace of mind.
Can I place objects on top of the subwoofer?
No, keep the top surface clear. The subwoofer needs free air circulation around the driver and port to prevent overheating and to avoid sound distortion.
Where can I get replacement parts or service?
Contact an authorized Infinity service center for repairs or genuine replacement parts. Do not open the enclosure yourself, as this may damage internal components and void the warranty.
