THE BRAND WITH OVER 1,000,000 CUSTOMS

In choosing this fine Realistic product you have demonstrated a rather acute
awareness of the good old American custom called getting the most for your
money. With Realistic this is not an idle boast.

The "line was born in Boston, long famous for Yankee ingenuity - and thrift. lts
original intent was to bridge a gap between $100 equipment and $25 equipment
where, at the time, there was a real void in hi-fi merchandise.

Ear/y products were a $39.95 FM tuner, a $29.95 preamp/amplifier, a $79.95
speaker. Soon we found ourselves a unique niche as manufacturing retailers.

Capacity and ability grew simultaneous/y. Soon Realistic hi-fi products -
loudspeakers, receivers, tape decks, even tab/e radios - began receiving critical
acclaim for faultless performance as well as value. Dealers and franchises from all
over the world began requesting a Realistic franchise.

Today you can shop The Nationwide Supermarket of Sound I with the
confidence that youre getting the widest selection of quality hi-fi equipment
available anywhere - whether youre looking at budget-priced extension speakers
or true audiophile receivers.

Serial Number:

Your Realistic STA-2100 is a powerful and versatile AM/FM Stereo
Receiver. Designed by Radio Shack and made in our own factory, the
STA-2100 represents the latest in audio electronics engineering. A receiver
this powerful - 120 RMS watts per channel over the entire audio band - -
might have seemed unthinkable just a few years ago. But as you'll soon
discover, the benefits for you as a hi-fi listener are undeniable!

You can easily power up to two pairs of loudspeakers ~ even inefficient
systems - with your new Receiver. And of course, you can play your
music at "live-performance" levels (if the speakers can handle the power).

But more importantly, the STA-2100's ample power lets you enjoy sound
with plenty of headroom" at all volume levels. This means you'll hear the
subtle, instantaneous sound peaks that give music its live" quality. On
lower-powered receivers, there is often not enough reserve power available
to reproduce these peaks.

In addition, the STA-2100 offers a full array of controls and connection
jacks, so its capable of controlling even the most elaborate stereo system.

Read this manual carefully - it will help you get the most enjoyment
from your Receiver, from setting it up in your system to using all its
exceptional features. But first, you might like to know a little bit about the
innovative internal circuitry that makes it all possible.

0 FM front end uses an insulated-gate dual MOSFET amplifier for high
sensitivity, low noise and freedom from strong-signal overload.

0 FM IF employs a quadrature IC and triple ceramic filtering for superior
selectivity and rejection of unwanted signals.

0 PLL-Multiplex IC for wide and stable stereo separation. ,

O The AM section uses a newly developed AM tuner IC plus a three-gang
variable capacitor for superior reception of strong and weak signals and
freedom from unwanted signals.

0 Low-noise, wide dynamic range phono preamp features a built-in subsonic
filter to reduce or eliminate turntable rumble.

0 Speical noise cancelling circuitry eliminates switching pops.

O Elaborate relay protection circuits to handle thermal, overdriving or
speaker problems (shorting or otherwise).

0 Special protection against power-on current and voltage surges.

0 Full toroidal power transformer for efficiency and reduced hum leakage.
