Frequently Asked Questions - L-505uXII LUXMAN
How do I connect my turntable to the L-505uXII?
Use the PHONO input. If your turntable has a moving magnet (MM) cartridge, set the phono selector to MM. For moving coil (MC), you may need an optional MC transformer or built-in MC option if equipped.
What is the minimum speaker impedance for the L-505uXII?
The amplifier is rated for 4 Ω to 16 Ω speakers. Using speakers below 4 Ω may cause overheating or activate protection.
How do I activate the preamp output?
Connect your external power amplifier to the PRE OUT jacks. The internal amplifier is disabled when using the pre-out on most Luxman integrated amps; check the manual for your specific model.
Can I use the L-505uXII in a bi-wiring configuration?
Yes, by using two pairs of speaker cables per channel. Ensure the speaker terminals are properly tightened and observe polarity.
What should I do if the amplifier turns off suddenly?
This is likely due to the protection circuit activating. Check for shorted speaker wires, overheating, or impedance load below 4 Ω. Turn off, let it cool, and verify connections.
How do I clean the L-505uXII?
Use a soft dry cloth. Do not use chemical cleaners or spray liquids directly on the unit. Keep ventilation grilles dust-free.
Is a subwoofer output available?
Yes, there is a dedicated SUBWOOFER OUT jack. Connect a powered subwoofer. The output is line-level.
How do I switch between MM and MC phono input?
On the rear panel, locate the PHONO LOAD selector. Set to MM for standard cartridges, or follow the manual for optional MC settings (may require internal jumpers).
What is the purpose of the 'Loudness' control?
The LOUDNESS button boosts bass and treble at low volume levels to compensate for human hearing characteristics. It is recommended for quiet listening.
Can I stack other components on top of the L-505uXII?
Avoid stacking because the amplifier requires adequate ventilation. Place it on a stable surface with at least 10 cm clearance above and 5 cm on sides.
