Luxman 5 l 15 brochure

Page 1

The Luxman 5L15 integrated amplifier is rated
at 80 watts/channel minimum continuous power,
both channels driven into 8 ohms from 20 Hz to
20 kHz, with no more than 0.02% total harmonic
distortion. lntermodulation distortion is also a low
0.02% at rated output. Both the preamplifier and
power amplifier sections are direct-coupled DC
design, for high phase linearity, low transient
intermodulation distortion and extremely
wide-band response.

The preamplifier and power amplifier
sections both include Dual Monolithic Linear
Integrated Circuits (DML-le). These special,
LUX~developed le eliminate the danger of
DC drift and help achieve outstanding overall
performance. A class AB output stage and
high-speed transistors also contribute to high
performance, eliminating crossover (notch")
distortion.

Connections are provided for tuner, two tape
decks, two auxiliary sources and phono. A phono

Stereo integrated amplifier

subsonic filter can be switched to cut turntable
rumble. Dubbing and monitoring are provided
for two decks, and separate program source
listening is possible during tape-to-tape dubbing.
A muting switch permits preset volume
attenuation within a 715 to 740 dB range.

And illuminated power meters have adjustable
sensitivity, for full-scale readings at one-tenth

of rated power output.

Two DC sensing circuits protect amplifier and
speakers. lf excessive levels of DC exist, a
front-panel warning light goes on. A protective
blocking capacitor can then be switched into the
signal path. This switch also adapts the output for
use with electrostatic speakers.

Overall dimensions are standard for rack
mounting, and optional mounting brackets are
available. The units integral metal enclosure is
specially designed to nest compactly with other
LRS components. An optional vinyl-clad,
simulated wood-grain enclosure is also available.
