System 719 (130-1266) Installation Faxback Doc. # 7565 CONNECTING THE ANTENNAS NOTE: Do not connect the system to AC power until you complete all other connections. You can use the supplied indoor AM loop antenna and FM antenna to tune to local AM and FM stations. For the best reception, connect outdoor antennas. Your local Radio Shack store sells a complete line of outdoor AM and FM antennas and accessories. Connecting the AM Loop Antenna Follow these steps to connect the supplied AM loop antenna. 1. Position the AM loop antenna with the loop at 90 degrees to the base. 2. Loosen the AM and GND terminal screws on the back of the system unit, and wind the stripped ends of the antenna wires around the screws. Then, tighten the screws. 3. Position the loop antenna for the best reception. You can use screws (not supplied) to attach the antenna to the wall. Connecting the Supplied FM Antenna The supplied indoor FM antenna is usually adequate for FM reception in metropolitan areas. If FM reception is weak using the indoor antenna, connect an outdoor antenna. Connect the antenna to the FM 75 OHM ANTENNA terminal jack on the back of the multi-component system unit using a 75-ohm coaxial cable with a male F-connector and an F-to-PAL antenna adapter (such as Cat. No. 278-265, not supplied). Then, position the antenna for the best reception. CAUTION: Be sure to follow all the installation instructions described in the enclosed "Safety Instructions". CONNECTING THE SPEAKERS For the best stereo effect, place the supplied front speakers so the dis- tance between them is the same as the distance between the listening area and the point halfway between the speakers. If the distance between the speakers is greater, you can improve the stereo effect by angling the speakers toward you. To increase the bass effect, place the speakers in the corner of the room, against the wall, or directly on the floor. To decrease the bass effect, move the speakers slightly away from the corner, increase the distance be- tween them, or raise them 6 to 8 inches off the floor. You can purchase speaker stands at your local Radio Shack. In addition to the supplied front speakers, you can also connect another pair or front (or remote) speakers and a pair of rear speakers. You can use either or both pairs of front speakers using the selection switches on the stereo power amplifier unit (see "Selecting Speaker Systems"). Each speaker connected to the front (A or B) or rear speaker terminals on the system must have an impedance of at least 8 ohms. Your local Radio Shack store has a wide selection of speakers. For maximum bass response and best overall performance, connect your speakers so their polarities match each other (+ with +, and - with -). You can easily make the proper connections by using speaker wire coded to show the polarity. To help you properly connect terminals, one side of each pair of speaker wires is generally marked with a stripe or groove. NOTES: The insulation in some speaker wires is clear and the separated conductors are different colors. Your local Radio Shack store has a wide selection of speaker wire. Preparing the Wires 1. Split each speaker wire's two conductors for about four inches on each end. 2. Strip 1/2-inch of insulation from each conductor's end and twist the ends of each stranded wire. 3. Route the speaker wires to the appropriate speaker. Connecting the Front Speakers CAUTION: Do not let the bare speaker wires touch each other. This might damage the amplifier or speakers. 1. Press and hold the speaker terminal tabs labeled RIGHT SPEAKERS (FRONT) A on the back of the stereo power amplifier unit. 2. Insert the stripped end of the right speaker's brown wire into the system's negative (-) terminal and release the tab to lock the wire. 3. Insert the stripped end of the right speaker's yellow wire into the system's positive (+) terminal and release the tab to lock the wire. 4. Repeat Steps 1 through 3 for the left speaker. 5. Repeat Steps 1 through 4 to connect another pair of speakers to the right and left SPEAKERS (FRONT) B terminals. Connecting the Rear Speakers 1. Press and hold the speaker terminal tabs labeled RIGHT SPEAKERS (REAR) on the back of the stereo power amplifier unit. 2. Insert the stripped end of the right speaker's negative wire into the system's negative (-) terminal and release the tab to lock the wire. 3. Insert the stripped end of the right speaker's positive wire into the system's positive (+) terminal and release the tab to lock the wire. 4. Repeat Steps 1 through 3 for the left speaker. NOTES: If only one channel of the rear speaker is connected or if the sound at the front speakers is monaural, sound will not be heard from the rear speakers. If the speaker wires are near the AM loop antenna, they might interfere with reception. CONNECTING THE STEREO HIGH-POWER AMPLIFIER Follow these steps to connect the stereo high-power amplifier to the multi-component system unit. 1. Connect the amplifier audio input cord's phono plugs to the system's PRE OUT LEFT and RIGHT output jacks. 2. Connect the amplifier's surround control cord to the system's SURROUND CONTROL input jack. 3. Connect the amplifier's AC cord into the system's switched AC outlet. NOTES: The switched AC outlet's power turns off when the system's POWER turns off. The AC plug is polarized. If you have difficulty inserting the plug, do not force it. Turn it over and reinsert it. CONNECTING A TURNTABLE Plug a turntable's left and right audio cable's phono plugs into the sys- tem's PHONO LEFT and RIGHT input jacks. If the turntable has a ground wire, connect it to the GND terminal. CONNECTING VIDEO EQUIPMENT If you have a VCR, or other equipment such as a video disc player or a TV with line-level audio outputs, you can play it through your system. Connect the audio source's left and right output jacks to the VIDEO 1 or VIDEO 2 jacks on the back of the multi-component system unit. NOTE: Use shielded audio cables for this connection. CONNECTING POWER After you have made all connections, plug the system unit's AC cord into a standard AC outlet. The STAND BY indicator lights. NOTE: The AC plug is polarized. If you have difficulty inserting the plug, turn it over and reinsert it. (tlc/all-09/15/94)
