What is stereo?




There are now two system of high fidelity, monophonic (monaural) and stereophonic. Monophonic is a system that starts from one microphone and is fed through a single high fidelity set. Stereophonic is a double system. Two separate microphones are placed at different sides of the orchestra and two different systems are used to keep the two signals or channels separated. Two separate speakers are used, placed on different sides of you room. Stereo is much like 3-D photography, two slightly different sound reach your ears giving you a new dimension in sound.

Luxman R-117

The Luxman R-117 combines the state-of-the-art  technology of separate components into one affordable receiver.

Total Sonic Integrity
All Luxman receivers incorporate massive power supp;ies to deliver high dynamic power. The R-117 measures over 700 watts of dynamic power per channel (2 ohms) to ensure distortion-free transients.  The pre-amplifier section combines several Luxman exclusive circuit designs to optimize sonic accuracy, and the AM/KM stereo tuner is sonically competitive with the finest separate tuner in the world.
In all, the R-117 receiver provides the purity and musical warmth of the original source, plus the high dynamic power output necessary to ensure total sonic integrity at all volume levels.

Audio/Video remote Capability
The R-117 includes a hand-held remote to control the major functions of each Luxman audio component. In addition, the R-117 handpiece can select up to three video sources, and professional-grade video amplifiers are incorporated to maintain a high-quality picture. This single component will function as a complete audio and video control center with total remote capability.

Multi-Room Expandability
The R-117 also interconnects with an external remote eye to allow complete system operation from any room in your house. With a simple installation of cables and accessories, virtually all functions of the master system can be controlled at each remote location. This multi-room concept can be expanded at anytime in the future to include additional rooms.
 Long-Term Durability
A previous advantage of separate components over receivers has been in the area of durability. The R-117 is designed with a no-compromise approach to longterm reliability and is backed by a 5 year parts and labor warranty (the best in the industry)
The Luxman R-117 receiver is simply the finest sounding, most versatile, most reliable receiver in the world,   the ultimate component to upgrade your audio/video system.

"Ultimate Power" Recivers
The new R-117 receivers are excellent examples of Luxman's  "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 ohms loads, and 700 dynamic watts into 2 ohms. The amplifier section is backed by a massive triple-shialded high-energy power transformer and fast-recovery rectifier diodes to maintain high energy reserves under all load conditions.

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 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-117 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.
