STA-82 44-Watt AM/FM Stereo Receiver with Quatravox (310-2056) Features Faxback Doc. # 33307 INTRODUCTION Your new STA-82 is a highly versatile AM/FM Stereo Receiver which delivers enough power to drive almost any speaker system. The "honest" 22 watts per channel over the entire audio bandwidth will drive both "main" and "remote" speakers. And it has the performance and convenience features that distinguish a truly great receiver. Built-in Quatravox synthesizes 4-channel sound from ordinary stereo sources. Whenever you're ready, just add a second set of stereo speakers for the rear channels. It's the best of both worlds - stereo and 4 channel. With the FM tuner, the specifications tell the story. There's an FET front-end for excellent sensitivity and reduced noise. When you tune, muting eliminates interstation hiss. Our exclusive Auto-Magic dramatically simplifies FM tuning. when you touch the tuning knob, it lets you dial stations easily. Then as you release the knob, Auto-Magic fine-tunes the station and locks it in for drift-free listening. The wideband tuner provides maximum AM fidelity. And there are a lot of "little things" that show you how carefully we designed the STA-82. Things like easy-to-use Glide Path volume controls and a separate push-button power switch so you don't have to reset the volume every time you turn the receiver on. At Radio Shack we also believe a receiver should look as good as it sounds. So we built the STA-82 with a blackout dial and a dial pointer that changes from yellow to red to indicate stereo broadcasts. Like every Realistic component, the STA-82 comes with a beautiful oiled walnut case - and it doesn't cost you a penny extra. GUARANTEE: The Realistic guarantee is stated on the Guarantee Card packed with the receiver. It is in effect from coast-to-coast and in Alaska. At any time, Realistic equipment will be restored to new condition with original parts with MINIMUM delay anywhere in the U.S.A., usually right in your own neighborhood. In 98% of the cases, it is NOT necessary to return Realistic components to one of our Laboratories. NOTE: Before operating your STA-82 for the first time, please read these documents carefully. It will tell you how to connect your receiver and how to get the most enjoyment from your system. SELECTOR Chooses one of five input positions: AUX - For any high-output source - a second tuner, a crystal or ceramic phono cartridge, a second tape deck, TV, Ham radio, etc. PHONO - For any turntable equipped with a magnetic cartridge. FM - Activates the built-in FM tuner. FM MUTING - Activates the built-in FM tuner and eliminates interstation hiss. AM - Activates the built-in wideband AM tuner. STEREO/MONO When pressed in, switches the amplifier and tuner from stereo to monaural operation. In the out position, the amplifier operates in stereo and the FM tuner automatically switches to stereo when there is a stereo signal. TAPE MONitor Push in to play tapes or to monitor a tape as it is being recorded. HI FILter When pressed in, minimizes hiss, scratches and other high-frequency noise. AUTO-Magic With the button out, the AUTO-MAGIC beacon on the tuning dial lights and special circuitry simplifies FM tuning. When pressed in, FM tuning is manual. PHONES Accepts any pair of low impedance stereo headphones. The jack is always "live." LOUDNESS With button out, boosts high and low frequencies to compensate for the ear's reduced sensitivity to bass and treble at low volume. Radio Shack's exclusive Perfect Loudness adds just the right amount of compensation at every listening level. Pressing the button in removes the compensation. SPEAKERS OUT - Turns all speakers off for private headphone listening A - Connects main speakers only B - Connects remote speakers only A+B - Connects main and remote speakers QUATRAVOX - Synthesizes 4-channel sound. "A" speakers become front channels, "B" speakers are rear. BASS Controls low frequencies. At the center position, it does not effect the sound. Turn clockwise to boost bass response, counterclockwise to de-emphasize the low frequencies. TREBLE Controls high frequencies. At the center position, it does not effect the sound. Turn clockwise to boost treble response, counterclockwise to de-emphasize the high frequencies. POWER Turns the receiver on when pushed in - off when pushed a second time. LEFT and RIGHT VOLUME Adjusts volume and balance. Tuning Knob Tunes AM and FM stations. In the Auto-Magic mode, touching the knob changes the TUNING meter light from green to white and permits easy station selection. TUNING Meter Indicates the relative strength of FM and AM signals. Tune for the highest reading. Dial Pointer Lights yellow when listening to AM or FM. The pointer turns red when the STEREO/MONO button is out and there is an FM stereo signal. AUTO-MAGIC Beacon Lights when listening to FM with AUTO-Magic button pressed in. Blackout Dial Lights whenever the receiver's power is on. REAR PANEL 1. UNSWITCHED Convenience Outlet - Powers any audio accessory up to 200 watts. The front panel POWER switch does not effect this receptacle. 2. AC CORD - Supplies the receiver's power. Plug the cord into any 120 VAC, 60 Hz outlet (220/240 VAC, 50 Hz power where the sets are so marked in the rear for European and Australian models.) 3. POWER FUSE - Protects the receiver from voltage surges, short circuits and other abnormal operating conditions. If the dial light does not go on when POWER is pressed, check the fuse. If it is blown, replace it with an identical size and value. 4. "B" SPEAKERS - Powers remote/rear speakers. 5. "A" SPEAKERS Phono Jacks - Connects to speakers with phono jack connectors. NOTE: Use either phono jacks or screw terminals for A speakers, not both. 6. "A" SPEAKERS Screw Terminals - Powers main/front speakers which do not have phono jacks connectors. NOTE: Use either phone jack or screw terminals for "A" speakers, not both. 7. TAPE IN - Accepts output from any tape deck or recorder for tape playback. 8. TAPE OUT - Permits tape recording any source chosen by the SELECTOR. The output from these jacks is uneffected by the front panel controls. 9. AUX - Accepts output from any high-level source - a second tape deck or tuner, a ceramic or crystal phono cartridge, etc. 10. PHONO MAG - Accepts output from any turntable equipped with a magnetic cartridge. 11. PHONE GND - Accepts the green or black ground wire found on most turntables. Making this "ground" connection reduces or eliminates hum. 12. FM Linecord Antenna - Connects to 300 Ohm FM screw terminal to provide FM reception in most metropolitan areas. Remove the linecord antenna when attaching an external FM antenna. 13. FM ANTenna 300 Ohm - Connects to antennas using standard 300-Ohm lead-in. 14. FM ANTenna 75 Ohm - Connects to antennas using 75-Ohm coaxial lead-in. Coaxial cable provides extremely high resistance to static and other noise. 15. AM ANTenna - Connects to external AM/shortwave antenna for long distance AM reception. In most areas the built-in antenna will provide excellent reception. (SP/EB 5/22/96)
