Luxman has
perfected sonic reproduction with amplifiers that capture the best of both
worlds; the warm musicality associated with vacuum tube amplifiers, plus the
high power needed for today's digital source material. In other words,
"guality plus quantity".
For over 60
years, Luxman components have earned the highest accolades for their musical
warmth and transparency. In the past, however, Luxman's amplifiers were
designed to deliver optimum results with analog source material and
conventional loudspeaker design. Now, the increased popularity of the compact
disc format has created a new demand for higher power output.
The Digital
Era
Compact
discs have a dynamic range that far exceeds that of phonograph records and
cassette tapes. This requires amplifiers with greater reserve power to smoothly
handle the dramatic changes in dynamic impact.
In addition,
the clarity and wider dynamics of CD's have encouraged speaker manufactures to
introduce new design with improved sonic performance. However, several of these
new speaker designs expose amplifiers to extremely low impedance loads that
demand higher current output. Plus the
CD's remarkable sonic realism has also ignited a whole interest in listening to
music that, in many households, has resulted in multip;e speaker arrangements
and multiple-room speaker installations. These combined loads pose additional
threats to the stability and clarity of an amplifier with insufficient reserve
power.
The new
Luxman Amplifiers
To ensure
the sonic integrity of CDs into a variety of speaker loads, an amplifier must
be able to deliver high dynamic power. In answer to this, Luxman has
incorporated massive power supplies with high energy reserves to ensure
distortion-free transients.
High-current, bipolar transistors are then carefully selected in matched
pairs to preserve total sonic integrity at high dynamic levels. This rugged design technique accomodates the
high demands of both digital software and low impedance loads. But high power
is only half the story …
Ultimate
Fidelity
The
heart of Luxman amplifiers is still the warm, musical feeling that has resulted
from decades of research on how vaccum tube amplifiers reproduce music so
faithfully. To achieve this same type of "tube-like" transparency and
naturalness, Luxman transistor amplifiers employ voltage driven amplification
configurations that perform the main current conversion only at the
output. In addition, sophisticated
circuit designs, including Duo-βeta
circuitry, STAR circuit patterns and LED bias circuitry, are utilized to obtain
that extra degree of musical purity that conventional amplifiers ignore.
Ultimate
Power
The best of
both worlds. It's the purity and musical warmth of the original source plus the
high dynamic power output that combine to ensure total sonic integrity at all
volume levels. In today's luxman
amplifiers, we call it "Ultimate
Power".
"Ultimate
Power" Recivers
The new
R-115, R-117 and R-113 receivers are excellent examples of Luxman's "Ultimate Power" amplifier designs.
The R-115
rated at 70 watts, can provide up to 200 dynamic watts into 4 ohms, and 270
watts into 2 ohms loads. And, with its heavy, double-shielded power transformer
and high efficiency, it provides a full 3 dB of dynamic headroom.
Both
incorporate a new 5-gang varactor, dual-gate MOSFET FM front end, with
automatic hi-blend circuitry, that ensures clean, distortion-free FM
performance.
All three
receivers employ voltage amplifications circuitry that ensures the
"tube-like", musical warmth of traditional Luxman amplifiers. In addition,
CD Straight circuitry routes CD input signals past all signal processor
and switching functions to provide optimum accuracy, imaging and impact.
Complementing
this performance are an array of advanced features that lend versatility and
precise control over a wide range of functions . Both the R-115 even include a hand-held
remote that can operate a complete system of components.
The Ultimate
Upgrade
All three
Luxman receivers include pre-out connections for upgrading in power output to
the awesome M-117 power amplifier.
