Frequently Asked Questions - ALS-LFI350 ATLAS
How do I connect the ALS-LFI350 speaker to my amplifier?
Use the dual binding posts on the back of the speaker. Connect the amplifier's speaker wire to the terminals, ensuring positive to positive and negative to negative. For bi-wiring, remove the metal jumpers and use separate cables for the tweeter and woofer sections.
What is the impedance of the ATLAS ALS-LFI350?
The impedance is 8 ohms, which is compatible with most home amplifiers and receivers. Always check your amplifier's specifications to ensure it can drive 8-ohm loads.
How should I clean my loudspeaker?
Turn off the speaker and let it cool down. Wipe the cabinet with a soft dry cloth. Do not use water, solvents, or abrasive cleaners. For the grille, gently vacuum with a brush attachment if needed.
Can I use the ALS-LFI350 outdoors?
No, this speaker is designed for indoor use only. Exposure to moisture, extreme temperatures, or direct sunlight can damage the cabinet and drivers. Keep it in a dry, temperature-controlled room.
What type of amplifier is recommended for this speaker?
An amplifier with 25 to 150 watts per channel at 8 ohms is suitable. Avoid using low-power or high-power mismatches; too little power can cause clipping, while excessive power may damage the drivers.
How far from the wall should I place the speakers?
For optimal bass response, place the speakers at least 20 to 30 cm away from the back wall. The bass reflex port is on the rear, so leaving space allows proper air flow and reduces boomy sound.
Why is there no sound coming from my speaker?
Check the connections: ensure the speaker wires are securely attached to both the amplifier and the binding posts. Verify that the amplifier is set to the correct output channel and not muted. Also confirm the balance control is centered.
Can I wall-mount this speaker?
No, the ATLAS ALS-LFI350 is a floor-standing speaker and is not designed for wall mounting. It should be placed on a stable, level surface or on its included rubber feet on the floor.
What should I do if the sound is distorted?
Distortion often occurs when the amplifier is overdriven. Lower the volume to a level below the clipping point. Also, be sure the speaker is not placed too close to a corner, which can cause excessive bass and muddy midrange.
Is the speaker magnetically shielded?
Yes, the ALS-LFI350 is magnetically shielded, reducing interference with older CRT televisions or monitors. However, for modern flat screens, it is not necessary but still safe to place nearby.
