STA-7500 (310-2107) Connections Faxback Doc. # 6499 CONNECTING AUDIO SOURCES You can connect a turntable and a tape deck to the receiver. You can also connect two other audio sources such as a TV, a VCR, or a CD player. Guidelines for Connecting Audio Sources Use only shielded audio cable with RCA-type connectors (not supplied). Your local Radio Shack store sells the required cable. Connect each source's left channel output to the receiver's corresponding L input jack. Connect each source's right channel output to the receiver's corresponding R input jack. Connecting a Turntable Use a turntable with a magnetic cartridge. For better sound and less wear on your records, we recommend a cartridge with an elliptical stylus. Note: The output voltage for older ceramic-type cartridges is too high and could damage the receiver. Most newer model turntables use a magnetic cartridge. Connect the turntable to the receiver's PHONO jacks. Connect the turntable's ground wire to the receiver's PHONO GND terminal. Connecting a Tape Deck Today's high-performance tape decks have special tape bias settings and noise-reduction circuitry. Some decks also offer advanced recording and dubbing capabilities. Radio Shack's Optimus SCT-7500 (Cat. No. 14-667) or SCT-7500 (Cat. No. 14-668) offers the added convenience of remote operation using the receiver's remote controls. Connect the tape deck's output jacks to the receiver's TAPE IN jacks. Connect the receiver's TAPE OUT jacks to the deck's input jacks. Connecting Other Audio Sources Connect the audio outputs of other audio sources, such as a TV, VCR, or CD player, to the TV/VCR, CD, or AUX jacks. These three sets of jacks are identical in function, so you can use each of them with any audio source that has standard line outputs. The jack's names help you associate the connections on the back of the receiver with the selector buttons on the front panel. CD Players CD players are free from audible noise and distortion and provide a dynamic range close to that of a live performance. With proper handling, compact discs last indefinitely. Features such as search program, and repeat play make it easy to listen to your favorite tunes. Radio Shack's Optimus CD-5500 (Cat. o. 42-5036) or CD-7500 (Cat. No. 42-5038) offers the added convenience of remote operation using the receiver's remote control. TVs/VCRs You can connect your VCR or TV (if your TV has audio output jacks) to your receiver. This allows you to enjoy rich, powerful sound through your system's speakers when you watch TV programs and video cassettes. For the best audio performance, we recommend a VHS Hi-Fi VCR. CONNECTING THE REMOTE CABLE If you use an Optimus SCT-5500/7500 cassette deck or a CD-5500/7500 CD player with this receiver, you can use the receiver's remote control to operate the other component. Use the remote control cable to connect the receiver's DIGI LINK or DECK PAUSE jack to the other component's DIGI LINK or DECK PAUSE jack. This relays the remote control signal from the receiver to the other component. CONNECTING ANTENNAS In many cities, the supplied AM loop antenna and FM line-cord antenna provide adequate reception. The FM line-cord antenna (shown below) is already connected to the receiver. It uses the AC power line to receiver FM signals. However, for the best radio reception in any area, use an outdoor antenna. Your local Radio Shack store sells a wide selection of outdoor antennas. Connecting the Supplied AM Antenna Assemble the antenna's base by swinging the base in the direction of the arrow as shown and snapping the tabs into the groove. Then attach the antenna wires to the receiver's AM ANT terminals. Place the antenna on top of or next to the receiver. If the receiver is in a rack or on a shelf and there is no room for the AM loop antenna, you can hang the antenna with the keyhole slot. Hang the antenna as close to the receiver as possible. If the wire between the AM loop antenna, and receiver is too short, you can add extra wire. Extra antenna wire is available at your local Radio Shack store. Connecting an Outdoor AM Antenna Connect the outdoor antenna's AM wire to receiver's AM ANT terminal. Use a separate piece of antenna wire to connect the AM ANT GND terminal to an earth ground, such as a metal cold-water pipe. Caution: Do not connect an antenna ground to a natural gas pipe. A spark could possibly ignite the gas, causing an explosion. Note: Radio Shack's shortwave antenna kit makes an excellent outdoor AM antenna. Connecting an FM Antenna You can also connect a rabbit-ear TV antenna (for indoor use only) or an outdoor VHF/UHF TV antenna for FM reception. Radio Shack stores carry a full line of quality outdoor antennas and antenna connection accessories. Notes: Use a VHF/UHF/FM splitter (not included) to connect an antenna to both the receiver and a TV. The drawing below illustrates how to split the antenna connection. For the best FM reception, use 75 ohm coaxial cable to connect an outdoor antenna to the receiver. However, if your existing antenna installation uses 300 ohm twin head cable, you can also use it to make the connection. First, disconnect the FM line-cord antenna from the receiver's FM ANT 300 ohm terminal. Then connect the antenna wire as follow depending on the cable type. If the antenna wire is 75 ohm cable: 1. With a stripping tool, remove about 1 inch of the 75 ohm cable's outer insulation to expose the cable's shielding. Then fold back the shielding from the inner insulation. 2. Strip off about 1/2 inch of the inner insulation around the center wire. 3. Pull the shielding back over the inner insulation. Insert both the shielding and wire through the metal clamp connected to the FM ANT GND terminal. Then, connect the center wire to the receiver's FM ANT 75 ohm terminal, and secure the shielding with the GND terminal's clamp. Caution: The cable's shielding should only touch the GND terminal. If the antenna wire is 300 ohm twin-lead cable, connect each lead to one of the receiver's FM ANT terminals. CONNECTING TO POWER Connect the receiver's power cord to any standard AC outlet. Switched Power Outlets The two outlets on the back of the receiver provide AC power for other system components, such as a compatible CD player or cassette deck. The outlets are switched (they turn on and off with the receiver). Warning: To avoid a fire hazard and to protect the receiver, do not connect a device with high power consumption (such as a heater, iron, hair dryer, television, or refrigerator) to either outlet.
