Frequently Asked Questions - S15A Proel
How do I connect the S15A subwoofer to my PA system?
Use a balanced XLR cable from your mixer or crossover output to the INPUT XLR connector on the subwoofer. For daisy-chaining to another sub, use the OUTPUT XLR jack. Ensure the phase switch matches the orientation of your other speakers.
What is the recommended crossover frequency for the S15A?
Set the low pass filter (LPF) between 80 and 120 Hz depending on your main speakers. Start at 100 Hz and adjust for seamless integration. The variable LPF control allows precise setting.
Why is there no sound coming from my S15A?
Check power supply and ensure the power switch is on. Verify signal cable connection and that the source is active. Look at the front LED: green indicates normal operation, red indicates protection mode (overload/overheat). If red, let it cool down.
Can I use the S15A outdoors?
Yes, but it is not weatherproof. Protect it from rain and direct sunlight. Use a cover when not in use. Ensure proper ventilation to avoid overheating.
Does the S15A have a built-in crossover?
Yes, it includes a variable low‑pass filter (80–120 Hz) and a phase switch (0/180°) to optimize integration with full‑range speakers.
What are the dimensions and weight of the S15A?
Dimensions are approximately 520 x 600 x 550 mm (W x H x D) and weight is about 30 kg. Always use two people to lift and position the subwoofer.
How do I clean and maintain my S15A subwoofer?
Disconnect power. Wipe the enclosure with a dry, lint‑free cloth. Do not use solvents or harsh cleaners. Keep ventilation grilles free of dust. Periodically check cable connections.
What is the power consumption of the S15A?
Maximum power consumption is about 800 W under full load. In standby or idle, consumption is significantly lower. Use a power outlet rated for at least 10 A.
Is the S15A compatible with 100V line systems?
No, it is designed for low‑impedance (8 ohm) operation with an internal amplifier. It requires a standard AC power outlet (100–240 V). It cannot be used directly on a 100V line.
What should I do if the amplifier goes into protection mode?
Protection mode (red LED) indicates overload, overheating, or short circuit. Reduce volume, improve ventilation, and ensure impedance is not too low. Let the unit cool for 10 minutes before restarting. If persistent, contact Proel service.
