Frequently Asked Questions - Aurora XT Sub 30A HECO
How to connect the Aurora XT Sub 30A subwoofer to my amplifier?
Use an RCA cable from the amplifier's LFE output to the subwoofer's LFE input. If your amplifier does not have an LFE output, connect the subwoofer's high-level terminals in parallel with the main speakers.
What is the best position for the subwoofer?
Place the subwoofer near a wall or in a corner to reinforce bass. Avoid obstacles and test different positions for balanced sound. The distance from the rear wall affects the frequency response.
How to adjust the crossover frequency?
Set the crossover frequency on the subwoofer (typically between 80 and 120 Hz) according to your main speakers. For bookshelf speakers, 80 Hz is a good starting point. Adjust by ear until you get a seamless transition.
What is the phase adjustment for?
The phase adjustment (0–180°) allows aligning the timing of the subwoofer with that of the main speakers. In the 0° position, both reproduce the signal simultaneously. If the bass seems weak or out of sync, turn the knob until you get the fullest level.
What to do if the subwoofer does not turn on?
Check the power cable, mains socket, and on/off switch. Make sure the auto standby mode is not triggered by a too weak signal. If the problem persists, contact after-sales service.
How to clean the subwoofer?
First unplug the device. Use a soft dry cloth to wipe the surface. Never use chemicals, alcohol, or abrasive wipes. Avoid letting moisture enter the ventilation slots.
Can I use the subwoofer with a 2.1 audio system?
Yes, the Aurora XT Sub 30A subwoofer is designed to be integrated into a 2.1 system. Connect it to the LFE output of your amplifier or to the high-level terminals. Adjust the volume and crossover to your preference.
The subwoofer emits a hum, what to do?
A hum can come from incorrect grounding or interference. Check cable connections, use shielded cables, and move the subwoofer away from sources of electromagnetic interference. If the problem persists, reverse the polarity of the mains plug (polarity adapter).
What is the recommended maximum power of the amplifier?
The subwoofer is active and has its own built-in amplifier of 200 W RMS. There is no need to supply external power. Simply plug it into a mains socket.
How to resolve an unintentional triggering of protection?
The protection triggers in case of short circuit or overheating. Check the connection cables, ensure the ventilation slots are not blocked. Reduce the volume if the device is pushed to the max. Let it cool down before using again.
