Luxman L-3

 Luxma L-3 is a solid state stereo integrated amplifier. The L-3 was so designed as to offer diverisfied facilities, while retaing the slim, precision-look common to our prestigeous line of "laboratory Reference Sries" and "Laboratory Standard Series"

Totally direct-coupled amplifier circuitry at the power amp section with dual rail power supply offers a high damping factor at the ultra bass range to ensure efficient driving of loudspeakers. To reduce the crossover distortion down to the minimum level, a through complementary configuration is employed at the output stage by means of PNP and NPN transistors, while the driver transistors have extremely good heat-dissipation to ensure high dependability. Transistors having high cut-off frequency are used in the driver stage to help reduce distortion in the treble range.

 Specialy selected low noise transistors and resistors in conjunction with low leakage type electrolytic capacitors realize good S/N ratio.

The 2-stage equalizer amps using PNP and NPN transistors not only offer outstanding linearity but handle sufficiently high input voltage (150 mV, 1khz, RMS)

LUX's well-known NF type tone controls are provided independently for both right and left channels and make it possible to tailor reproduced sound according to your own state. At the center-click point a true flat frequency response is obtained. A high-cut filter is provided to remove unpleasant tape hiss, disc scratchnoise etc., while subsonic filter is useful to get rid of all the bad effects of turntable rumble and infrasonic disc noise.. A loudness control is employed for proper compensation at low level of listening. 2 pairs of tape monitor circuits permit dubbing from one tape to another.

The speaker selector allows you to drive either A and B speakers separately or both of them simultaneously.

 Styling of L-3

A truly high quality precision image was achieved in this audio component thanks to its meticulous finish of totally metallic structure. Aluminium extruded front panel provides an optimum match with the elegant case and precision metalic knobs. The exhaustive study of human engineering is reflected in the placement of the various knobs and controls for easiest and most logical operation.
