Ultimate Power.

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 todays
digital source material. In other
words. quality plus quantity."

For over 60 years, Luxman
componean 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
designs. Now, the increased
popularity of the compact disc
format has created a new demand
for higher power output.

T/Ie 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 CD5 have
encouraged speaker manufacturers
to introduce new designs 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 CDS remarkable
sonic realism has also ignited a
whole new interest in listening to
music that. in many households,
has resulted in multiple 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 lnxman 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 incor-
porated 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
accommodates 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 ampli-
fiers is still the warm, musical
feeling that has resulted from
decades of research on how
vacuum 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-Beta
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 com-
bine to ensure total sonic integrity
at all volume levels. In todays
Luxman amplifiers, we call it
Ultimate Power".

Ultimate Power Receivers.

The new R-ll7, R-llS and
R-113 receivers are excellent
examples of Luxmans Ultimate
Power" amplifier designs.

The R-117, rated at 160
watts per channel, is capable of
supplying up to 600 watts of
dynamic power into 4-ohm loads,
and 700 dynamic watts into 2
ohms. The amplifier section is
backed by a massive triple-
shielded high-energy power
transformer and fast-recovery
rectifier diodes to maintain high
energy reserves under all load
conditions.

Similarly, the R-115, rated at
70 watts. can provide up to 200
dynamic watts into 4 ohms, and
270 watts into Z-ohm loads. And,
with its heavy, double-shielded
power transformer and high
efficiency, it provides a full 3dB 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.

The R-113, the most afford-
able model in Luxman's new line
of receivers, includes a high-speed
dynamic amplifier that delivers up
to 100 dynamic watts into a 2-ohm
load. And a high-efficiency toroidal
power transformer is coupled with
high-energy storage capacitors to
provide the dynamics and steady-
state reserves necessary for the
most demanding music transients.

All three receivers employ
voltage amplification 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

Complementing this
performance are an array of
advanced features that
lend versatility and
precise control over
a wide range of
functions. Both
the R-117 (l

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-ll7 power amplifier.
