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.

Rotel RX-602 receiver

AM/FM Stereo Receiver

Add a high performance, high-sensitivity tuner to advanced PLL MPX circuitry, then add a high-power, low-distortion power amplifier to all the other RX-602 features, and what does it all add up to. An experience in sound that you'll not only want to have around to set the pace of your living room enjoyment, but one you'll also find hard to resist because the price makes the professional quality so readily accessible.

 

A high-performance, high-sensitivity tuner

For truly fantastic sound enjoyment, the high-performance,, high-sensitivity tuner Rotel engineers for the RX-602 gives you super high sensitivity, excellent rejection characteristics, and distortion  so low it's negligible. For a big boost in selectivity along with fasting reliability, ceramic filters and advanced integrated circuitry go snugly into the FM IF section.

 

The Power Amp

It's high-power, low-distortion all the way. With split power supply and 100% directly coupled OCL circuitry (OCL circuitry has low-noise silicon transistors that give 40W/40W continuous music power into 8 ohms at less than 0,5% T.H.D. both channel driven - or 35W/35W RMS continuous power into 8 ohms at less than 0,5% T.H.D. both channel driven from 20 to 30,000 Hz). If that's not superb output, you tell us what is.

Advanced NF and IC equalizer amp

Advanced because of the advanced electronics - low-distortion , 2-stage directly coupled NF (Negative Feedback) circuitry with high-voltage integrated circuitry achieve genuinely outstanding RIAA characteristics. For terrifically transparent reproduction quality, tone control circuitry also features directly coupled negative feedback circuitry.

 

FM and Audio Muting

FM muting effectively removes inter-station noise during tuning. Audio muting instantly lowers the volume level by -20 dB without disturbing the volume setting when temporary lowering of volume is necessary.

 

Extra-wide Linear FM dial scale and large tuning

The extra width of the linear FM Dial scale results in easy , precise tuning. The size of the vernier scale makes it easy to see. Large tuning meters complement this ease all the more with smooth flywheel action knob that get you right-on to a station quickly.

 

PLL MPX section

Utilization of PLL (Phase Loock Loop) integrated circuitry and other improved circuitry in the MPX section allows for effective stereo esparation and excellent frequency response. Distortion never gets in the way of stereo enjoyment.

 

The performance and the advanced electronics that make RX-602 enjoyment possible are enclosed in a cabinet that stands out in any system; hair-line brushed extruded aluminum front with luxury  metal knobs. Cabinet itself has a beautiful simulated walnut finish. This long, lean look is human-engineered up, down, and all-around to be a great looker and an equally great performer.
