Description
@
The Integrated Amplifier of L series which introduced the technology developed with the high-end model.

In order to send out the stable energy to a speaker, the Oide power transistor and the large-sized heat sink are adopted.
Moreover, the efficient large-sized EI core power transformer and the mass capacitor excellent in the instant charge-and-discharge property were carried, and the effective output of 70W+70W has been obtained.

The high slew rate CSSC (Complementary Single Stagger Circuit) super-wide band amplifying circuit which was excellent in the instantaneous power of sound in the wide band is adopted as an amplifier circuitry.

ROM optical disk (Optimized Dual) beta circuit is carried.
It was used in order to secure the stability of the direct-current area of amplifier, but by the way of inserting DC servo amplifier etc. in a feedback loop, the feedback of general DC had become a cause by which the tones for every band differed in order to put in a process which is different only to DC area.
In L-501s, though the dependency to a corrective network is reduced by improving the nakedness property of a circuitry and a direct-current region and each alternating-current region are considered as another feedback, the unification of the tone covering the stability and all the play bands of a circuitry is realized, without using DC servo amplifier.

The STAR circuit original with a Lux is adopted, sharing of the feed line in a circuitry or an earth line is abandoned, and the loop which became independent, respectively consists of connecting the whole of each line with each block or a signal path directly from a reference point.
This removes the variation factor of the amplification reference point by the cross interferencee between each circuitry, or transition of the signal current, and the cleaner music play is aimed at.

Two lines are carried in the speaker terminal as a bi-wiring interconnection correspondence.
Moreover, the vice type screw type which holds a cable firmly is adopted, and the banana plug is also supported.

The input only for man month is carried and phone amplifier is built in.

The motor drive scheme is adopted as a volume and an input selector.

Functionalities, such as a loudness, a Subsonic Filter, a feather r eggplant control, a mono-switchpoint, and a tone control, are carried.
Moreover, the straight switchpoint is carried and a tone quality with a higher purity is obtained by making a signal path simple.

Phase-in barter is carried and a phase switching of a balance line (XLR) input is possible.

The line phase sensor is carried and a polar mandatory is possible.

Relay contact only for headphone was given to the headphone jack, and it has the headphone circuitry of another system with the output to a speaker termination.

A power switch, an input selector, volume control, and the remote control in which the fundamental operation of a muting is possible are attached.
Moreover, the bus line which interlocks the compact disk player made from LUXMAN and a remote control operation is also carried, and the operationality of a systemwide is raised.
