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-1030

 Model R-1030 Am/FM  Stereo Receiver
A new receiver from Lux with optimum cost/performance ratio. An exhaustive review of current circuitry and functions in receivers has made it possible to achieve greater simplicity whilsst still retaining the features indispensable to real High Fidelity. Power output 30W/channel into 8 ohms both channels driven with 0,05% total harmonic distortion.

Pre-Amp Section
Sound playback is possible from any of the FM, MW, Phono and Auxiliary terminals. A 2-stage direct coupled amp in the equalizer circuitry with PNP and NPN transistors gives good linearity and high input voltage at phono. Versatile contouring of the reproduced sound is possible with Lux's exclusive NF type tone control for bass and treble. High- and low-cut filters are useful to renmove tape-hiss disc noise and turntable rumble. A loudness control offers effective tonal compensation at low-level listening.

Main Amp Section
The direct coupled DC output configuration ensures the best possible bass and transient response and gives the amplifier excellent characteristics throughout. Today's almost mandatory full complementary symmetric output attains the least possible distortion, i.e.0,05% up to 30 W both channels driven into 8 ohms.

 FM Section
The front-end features a high grade 3-gang tuning capacitor to provide a satisfactory sensitivity at 2 µV, and 2 pairs of linear phase ceramic filter ensures good bandpass response. The superb figures provided by the PLL MPX IC in respect of distortion, separation and Signal-to-Noise will remain constant over a long period of time.
AM Section
A newly developed IC for AM reception makes it possible to obtain high sensitivity, low distortion and strong AGC, and the adoption of a ceramic filter of good selectivity ensures clean AM broad casting without interference, thus most AM stations become far more "listenable".
