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.
