Frequently Asked Questions - Aerius i Martin Logan
How do I set up the Aerius i speakers for the first time?
Unbox carefully, place speakers at least 2 feet from the wall. Connect speaker wires to the dual binding posts (ensure proper polarity). Plug the power cord into the wall; the electrostatic panel requires AC power. Turn on your amplifier and start with low volume.
What is the recommended amplifier power for the Aerius i?
Martin Logan recommends an amplifier capable of 20 to 300 watts per channel. The Aerius i has a nominal impedance of 4 ohms, so choose a stable amplifier that can deliver high current.
Can I bi-wire or bi-amp the Aerius i?
Yes, the Aerius i features dual binding posts that allow bi-wiring or bi-amping. Remove the metal jumpers between the posts and connect separate cables for the woofer and electrostatic panel.
How should I clean the electrostatic panels?
Use a soft, dry brush or a microfiber cloth to gently remove dust from the panel surface. Do not use any liquids, cleaners, or compressed air as they can damage the diaphragm.
Do the Aerius i speakers need a break-in period?
Yes, allow 30-50 hours of play time for the speakers to reach optimal performance. During this period, the bass driver suspension and the electrostatic panel will settle.
What is the correct toe-in angle for the Aerius i?
Start with a slight toe-in of about 5-10 degrees, aiming the speakers directly at the listening position. Adjust based on your room acoustics and personal preference.
Why is there a power cord on a passive speaker?
The Aerius i is a hybrid design: the bass section is passive, but the electrostatic panel requires AC power to charge the diaphragm. The power cord provides the bias voltage needed for electrostatic operation.
What should I do if there is no sound from the electrostatic panel?
Check that the power cord is plugged in and the power switch is on. Ensure the amplifier is connected properly. If the problem persists, the panel may need service – contact Martin Logan support.
Can I place the Aerius i near a TV or electronic equipment?
Yes, but keep at least 2 feet of distance to avoid magnetic interference with CRT TVs. For modern flat-panel TVs, interference is minimal. Ensure good ventilation.
How do I replace the spikes on the Aerius i?
Unscrew the existing rubber feet or spikes. Insert the new spike into the threaded insert and tighten by hand. Use the included lock nuts to secure them. Adjust for leveling.
