Frequently Asked Questions - L-595ASE LUXMAN

How do I reset the L-595ASE to factory defaults?

Turn off the power. Then hold down the OPERATION button on the main unit for at least 5 seconds and press the LINE STRAIGHT button once while holding OPERATION. The power will switch off and settings will reset to defaults: input LINE-1, speakers A, subsonic off, mono off, loudness off, line straight off, separate off.

Why is there no sound from the speakers?

Check that the volume control is not at minimum, the correct input source is selected, and cables are securely connected. Ensure the MUTE button on the remote is off and the SEPARATE button is set to off. If using headphones, set SPEAKERS to OFF.

How do I connect a turntable?

Connect the turntable's output to the PHONO terminals. For MM cartridges, set input selector to MM; for MC, set to MC. Connect the ground wire to the SIGNAL GROUND terminal. If the turntable has a built-in phono stage, use a LINE input instead.

What does the LINE STRAIGHT button do?

When LINE STRAIGHT is on, the signal bypasses the tone controls, balance control, loudness, subsonic, and mono circuits for the shortest, purest signal path. The indicator lights up when active.

How can I use the amplifier with an external power amp?

Use the SEPARATE function. Set the SEPARATE button to ON to feed the MAIN IN terminals directly to the power amp section. Connect the PRE OUT to your external amp's input. Volume must then be controlled by the external preamp or source.

The protection circuit keeps activating. What should I do?

The protection circuit activates due to overcurrent, high temperature, or DC offset. Disconnect the AC plug, wait a few minutes, then reconnect and power on. If it persists, check speaker connections for shorts, ensure ventilation is adequate, and consult your dealer.

Can I use speakers with 4 ohm impedance?

Yes, the amplifier is stable with 4 Ω loads when using a single speaker pair. However, when using both A and B speakers simultaneously, the combined impedance must be 8–16 Ω.

How do I clean the amplifier?

Use a soft, dry cloth. For stubborn dirt, lightly dampen the cloth with a neutral detergent, then wipe dry. Never use benzine, thinner, or abrasive cleaners.

What is the LECUA 1000 volume control?

LECUA 1000 stands for Luxman Electronically Controlled Ultimate Attenuator. It uses fixed resistance switching controlled electronically for precise, distortion-free volume adjustment from -87 dB to 0 dB in 1 dB steps.

Does the amplifier have a subsonic filter?

Yes, a subsonic filter is available via the remote control's SUBSONIC button. It cuts frequencies below the audible range to prevent turntable rumble or warped records from affecting the sound. The indicator lights when active.

Installation place

This unit should be installed in a well-ventilated location to enable heat dissipation because it is an A-class amplifier and generates considerable heat.

Especially, installation of this unit where direct sunlight is present, where the temperature rises excessively high such as close to a heater, or where it is humid or dusty may cause malfunctions even if the heat is efficiently released. Therefore, do not install this unit in such places.

Ventilation

The ventilation holes on the top and bottom panels of this product should never be blocked. If the amplifier is installed in closed rack or similar location, ensure ample space for cooling and leave the door open. Never place anything on top of the amplifier. Failure to observe these may cause malfunctions.

Note:

Ensure heat dispersal. Do not install this equipment in a confined space such as a book case or similar unit.

Precautions when connecting to other components

When connecting this unit to other input devices, such as a CD player, SACD player, D/A converter, tuner or recorder, be sure to turn off the power to this unit and all other connected devices first. Failure to observe this may generate a dangerous noise shock resulting in speaker damage and may cause malfunctions.

The connectors to each input terminal of this unit must be pushed in firmly. If the grounding terminal is inadequately connected, noise or hum, may be generated, resulting in an adverse S/N ratio.

Cautions when connecting speakers

When connecting to a speaker system, exercise extra care not to short-circuit between the positive and negative connections of the speaker terminals and the speaker input terminals of this unit. If a large signal is applied to the amplifier while it is short-circuited, a large current may be passed through the output circuit and cause malfunctions.

Sound is not generated shortly after the power supply is turned on.

This amplifier is equipped with a timed muting circuit to protect the output. Therefore, no sound will be generated for a short time after the power supply is turned on.

If the volume control is set to a high volume level before the timed muting circuit disengages, a loud, dangerous volume will be suddenly generated. Set the volume control to a low level first and then adjust it after you hear the output from the speakers.

Protection circuit

This product is equipped with a protection circuit that is activated upon detecting overcurrent, abnormally high temperatures and DC drifts to protect the amplifier and speakers. When the protection circuit is activated, the output to the speaker terminals will be shut off and the operation indicator will blink orange to show that this unit is muted. If the protection circuit is frequently activated, disconnect the AC plug from the wall outlet, wait for a while and then reconnect the plug to the wall outlet again and turn on the power. If the problem persists, please consult your dealer.

Repair and adjustment

When repairs or adjustments are needed, please consult the dealer who sold you the unit.

Cleaning

For cleaning, use a piece of soft fabric such as a cleaning cloth to wipe the unit. If dirt is hard to remove, use a small amount of neutral detergent to wipe it off and then wipe the unit with dry cloth. Do not use a solvent like benzine or thinner because they could damage the exterior.

Batteries

Warning: Batteries used for the remote control shall not be exposed to excessive heat such as sunshine, fire or the like.

Safety caution

Caution

This unit is heavy. Be careful when unpacking, carrying, and installing it.

New LECUA 1000 — LUXMAN Electronically Controlled Ultimate Attenuator 1000

The new LECUA 1000 has integrated an amplifier circuit and a high-precision attenuator by which uses electrically controlled fixed resistance switching. Fine sound volume is adjustable from 0 dB through -87 dB are achieved with no deterioration in sound quality.

ODNF — Only Distortion Negative Feedback —

The output section features LUXMAN's original distortion-only negative feedback system which enables a high-speed primary slew rate and ultra-wide audio bandwidth. Only distortion generated in the amplification process is fed back for cancellation. This maintains pure, high quality sound reproduction in the main amplifier section. Low impedance and a high signal to noise ratio for the transmission circuits are achieved thanks to the paralleled first stage and Darlington equipped second stage amplification circuits.

Also the input stage error detection circuits are triple-paralleled to moderate frequency characteristics and noise.

Since the latest version of ODNF-u uses dual transistors for the cascode circuit and the current mirror circuit, the error detection accuracy is improved by minimizing the difference between these elements.

Triple-paralleled push-pull output stages

Triple-paralleled bipolar transistors in push-pull configuration are used in the final output amplification stage providing a rated output of 30 W+30 W (8 Ω).

Highly stable power supply

The unit's highly stable power supply circuitry features a large capacity El-core-type power transformer with 8 custom designed 10,000 F blocking capacitors.

Parallel speaker relays

This unit is equipped with 2 large parallel speaker relays with a low resistance value to reduce the impedance of the speaker output lines.

Beeline construction

LUXMAN's Beeline construction ensures that the audio signal path takes the optimum shortest route from input to speaker output.

Selector switch IC

The selector switch IC, as used in our high-end C-900u control amplifier, supports high quality audio and improves input separation and crosstalk performance.

Schottky barrier diodes

By using Schottky diodes, manufactured by KYOCERA Corporation, this unit achieves very high DC conversion efficiency in the power rectifier circuitry and much less switching noise.

LUXMAN's original OFC wiring

Our original OFC cable, with non-plated core wire, is used for internal wiring to achieve smooth signal transmission. Extrathick 3.5 mm² copper cable is used in connections between the amplifier board output and speaker output board.

Non-angled circuitry

After carefully considering the delicate nature of the audio signal flow, non-angled circuit board tracking has been adopted to achieve smooth signal transmission.

Phono amplifier

This unit is equipped with an integral phono amplifier compatible with the MM/MC cartridge to achieve high-quality analog record reproduction without the need for an external dedicated phono amplifier.

Separate function

This unit is equipped with a “Separate” button used for separating the pre-amplifier and main-amplifier sections from each other. This enables bi-amp connections to an external power-amplifier and facilitates integration with an AV or home theatre system.

Loopless chassis structure

This unit features a loop-less chassis, independently constructed to eliminate increases in ground impedance due to chassis current.

Copper alloy RCA terminals

The RCA terminals used for the LINE-1 inputs are specially designed with the high conductivity of copper and the durability of brass.

18 mm pitch RCA terminals

We have used 18 mm pitch RCA input terminals for inputs other than LINE-1 to support high quality audio cables with large connectors.

Cast-iron insulators

For stability and support, this product features cast iron feet with vibration reducing density gradient.

Selector buttons

The source selector's individual buttons and indicators echo the design of our vintage L-570 masterpieces.

Large speaker terminals

The speaker terminals (A and B systems) have a separated inline layout (with the same characteristics for right and left) and are compatible with Y lugs to enable easy connection using extra-thick speaker cables.

Headphone output terminal

This terminal enables you to enjoy sound with headphones.

Aluminum remote controller
