Frequently Asked Questions - AP-S15LA Atlas Sound
How do I connect the AP-S15LA to an amplifier?
Use a professional speaker cable and connect to the Speakon or barrier strip inputs. Make sure the amplifier is off during wiring. Maintain correct polarity.
What amplifier power is recommended for the AP-S15LA?
The speaker handles 200W RMS and 400W program. It is safe to use an amplifier delivering up to 400W continuous at 8 ohms for optimum performance.
Can I connect multiple AP-S15LA speakers to one amplifier?
Yes, parallel connection is possible. With 8-ohm impedance, two speakers in parallel give a 4-ohm load. Ensure the amplifier can handle the lower impedance and total power.
Where should I place the AP-S15LA for best sound?
Place the speaker at ear level for the audience, or use a pole mount to raise it. Avoid corners and walls to reduce bass buildup. Tilt slightly downward for long-distance coverage.
How do I clean and maintain the loudspeaker?
Use a dry, soft cloth to wipe the enclosure and grille. Do not use water or solvents. Inspect cables and connections and check cabling for wear. Tighten loose screws periodically.
What should I do if the speaker produces no sound?
Check the cable connections, amplifier settings, and ensure the input selector is correct. Verify the speaker is not muted or blown. Test with another cable or channel. If the driver is faulty, replace the faulty component.
Is the AP-S15LA weatherproof?
It is not fully weatherproof. Use it only in dry locations or protect it from direct rain and moisture. For outdoor installation, use a weather-resistant enclosure or cover.
Does the AP-S15LA require an external crossover?
No. It has a built-in crossover that splits the signal between the woofer and tweeter. Just feed it a full-range signal from the amplifier.
Can the AP-S15LA be mounted on a speaker pole?
Yes, it has a 36 mm pole socket on the bottom. Use a standard pole or tripod stand, ensuring the pole is rated for the speaker weight and hold it securely.
What safety precautions should I follow?
Use stable support for mounting, avoid overloading the amplifier, and keep the speaker away from heat sources and moisture. Check all hardware and cables before use. Follow the power rating to prevent damage.
