IMPORTANT!

Please read this instruction manual carefully before installing your FM stereo
adapter. Taking a few minutes now, may save you considerablc time and effort
later on and will avoid the possibility of an improper installation. Be sure to
keep this booklet available at all times. It contains indispensable technical and
service information.

INTRODUCTION

IM Multiplexing depends upon the placing of two information channels
on one station carrier. The first information channel consists of the sum of the
loft and right stereo signals and is transmitted on the main carricr in the usual
manner. All existing monophonic FM receivers will treat this as a normal mono-
phonic signal. The listener equipped with a standard FM set is not aware that
storm) is living broadcast and his position is analogous to that of the black and
white TV sot owner who continues to receive a black and White compatible
picture cven when a colorcast is in progress. Thr- decoding element from which
stun-o is derived consists of the difference of the left and right signals (L-R).

The main carrier is modulated by a supersonic subcarricr which in turn is
modulated by the decoding clr-nwnf hit, The function of the FM stereo adapter
is to convert the two signals into left and right channels and produce the full
stcrcophonic effect. The broadcast is solely F.\[ with all of FM's advantages.

Listed below are several queslions and answers which should further help
explain FM stereo.

Question: Why 39 The GE Zenith System Chosen?

Answer: The GE Zenith system permits adequate opportunity to provide excel.
lent performance at relatively moderate cost. The frequency response
and distortion characteristics are consistent with high fidelity stand
:n-ds Stereo separation is good throughout the entire range. In short,
it offers a minimum degradation of conventional FM monophonic
response and a simple and effecliw method of achieving excellent
FM stereo.

Question: What Equipment Is Needed To Receive FM Stereo Broadcasts?

Answer: An FM tuner with multiplex output jar-k, multiplex adapter. dual chan-
nel amplifier and two speakers.

Question: Are There Any Special Antenna Requirements For Receiving FM
Stereo?

Answer: In difficult reception arcas, more sensitive and directional antennas,
both indoor and outdoor, might be required. The rcason for this is
that the decoding lltmtIlI of the signal is weaker and more susceptible
lo noise than regular monophonic programs.
