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.

The  Lafayette LA-226C is a self-contained instrument designed for the control and reproduction of all stereophonic and monophonic sources. Features a "pilot monitor"  stereo indicator which tells you instantly whether or not an FM station is broadcasting in stereo multiplex. The receiver section consists of an AM/FM tuner with built-in multiplex which provides more than 30 dB separation at 400 cycles. A sensitivity of 2 µV for 20 dB of quieting is achieved by the FM circuit with AFC defeat assuring reception of even the weakest signals. FM noise and filter slide switch cuts out unwanted station noise. The AM section features a superheterodyne circuit with AVC, and built-in ferrite loop antenna. The 40 watt amplifier section features large power fransformers and a frequency response of 20 - 20,000 cps ±2 dB. Less than 1,5% harmonic distortion on all modes.complete stereo preamp facilities provide dual concentric front panel controls for bass and treble, volume control balance, blend for variable channel separation from 5-position selection switch stereo to mono, (AM, FM, Stereo, Phono, Aux), 4-position amplifier mode switch (A, B, AB, REV), rumble filter slide switch, loudness slide switch, jack for stereo headphones, and On-Off power switch. Read controls include: Speaker phase switch, 8-16 Ω impedance selector switch , dimension control adjustment, speaker on/off switch, AC outlet, fuse and stereo tape outputs

Lafayette LR-3500


You won't and you can't
Because the LR-3500 is as good or better than any receiver around - including some that cost as much as half thousand dollars.
The top of the Lafayette line, the LR-3500 AM,FM and FM stereo receiver has all the features you've come to expect as the trappings of power. It'has state-of-the-art. Electronics, complete power controls to personalize the sound. 
The LR-3500 has more Continuous Power (RMS) than the Pioneer SX-737, Sony STR-7055, Sansui 771 and Kenwood KR-6400. Total Harmonic Distortion as low as the Pioneer and the Sansui. Better IHF FM Sensitivity than the Marantz 2250, the Sony, Sansui, Kenwood and Pioneer. And Capture Ratio that's better than the Sansui and equal to the Marantz and Kenwood.
Getting down to specifics, the LR-3500 puts out 47 Watts  per channel into 8 ohms from 20 - 20,000 Hz at no more  than 0,5% Total Harmonic Distortion. It has two tuning meters, two tape monitors, two stereo headphone output jacks, front panel tape output and mike inputs, FM MPX Phase Lock Loop Circuitry and loads of other features all packaged in a handsome walnut finish wood cabinet. And topped off with our 2 year free repair or replacement limited warranty on material and workmanship.
We know the Lafayette LR-3500 is a great $400 receiver because we've sold thousands of them at that price for years. But right now, it's an incredible $298 at your Lafaayette store.

It sounds too good to be true. But then, so does the LR-3500
