STAV-3370 Digital Synthesized Stereo (310-3032) Component Connections Faxback Doc. # 31165 CONNECTING PROGRAM SOURCES You can connect up to five external program sources to your receiver. CONNECTING A TURNTABLE Connect a turntable with a magnetic cartridge only. Some older turntables use a ceramic-type cartridge that does not work with this system. Connect the turntable's left and right cables to the receiver's left and right PHONO jacks. Then connect the turntable's ground wire to the receiver's GND terminal. Use a shielded audio cables with phono connectors for all audio connections. CONNECTING CASSETTE DECK(S) You can connect cassette decks to the VCR/TAPE 1 and the TAPE 2 MONITOR jacks. Connect the cassette deck's output jacks to the VCR/TAPE 1 IN (audio) or TAPE 2 PLAY jacks, and connect the input jacks of your cassette deck to VCR/TAPE 1 OUT (audio) or TAPE 2 REC jacks. You can connect a third cassette deck (for playback only) to the LD IN (audio) jacks. NOTE: If you place the cassette deck directly above, below, or to the left of the receiver, the receiver could interfere with the cassette deck's operation. If possible position the cassette desk to the right of the receiver or locate it away from the receiver. CONNECTING A CD PLAYER To connect a CD player to the receiver, connect the CD player's left and right output jacks to the receiver's L and R CD input jacks. CONNECTING VIDEO SOURCES If you connect two video sources such as VCRs or laser disc players to your receiver, you can use the receiver to switch between viewing the sources. You can also use the receiver to easily record from the video sources to the source connected to VCR/TAPE 1. NOTE: If your VCR is monaural, use a Y-adapter (available at your local Radio Shack store) to connect the VCR's audio output to both the L and R audio inputs on the receiver. Connect phono cables from a VCR's audio outputs to the receiver's VCR/TAPE 1 or LD IN (audio) jacks. Then connect phono cables from the receiver's VCR/TAPE 1 OUT (audio) jacks to the VCR's audio input jacks. Connect video cables from each video source's video outputs to the receiver's VCR/TAPE 1 or LD VIDEO IN jacks. Then connect video cables from the receiver's VCR/TAPE 1 VIDEO OUT jack to the VCR's video input. CONNECTING A VIDEO MONITOR The monitor (or TV with baseband video input) you connect to the VIDEO OUT terminal can monitor any program you connect to the receiver's VCR/TAPE 1 or LD input jacks. Then connect a video cable from the receiver's VIDEO OUT TO MONITOR TV jack to the monitor's video input. CONNECTING AN ADDITIONAL AMPLIFIER To increase the center channel's output power, you can connect an amplifier to the CENTER jack, as shown. Then connect the center channel speaker to the amplifier. CONNECTING THE ANTENNAS In many cities, the supplied indoor AM loop and FM antennas provide adequate reception. AM Antennas Assemble the included antenna's base by swinging the base in the direction of the arrow and inserting the antenna's bottom tabs into the base's slot. Then attach the antenna wires to the AM and GND terminals (bottom two terminals). Place the antenna on a flat surface and rotate it for the best AM reception. If the receiver is in a rack or on a shelf and there is no room for the AM loop antenna, use two screws (not supplied) to mount the base on the wall or another location as shown. NOTES: Keep the AM loop antenna connected even when you use another indoor antenna or an outdoor AM antenna. Ensure the antenna does not touch the receiver or other metal objects. Do not place the antenna near a CD player. a personal computer, or a TV set. If the wire between your AM loop antenna and receiver is too short, you can add extra wire, available at your local Radio Shack store. You can also use a Radio Shack shortwave antenna kit (Cat. No. 278-758), which makes an excellent outdoor AM antenna. FM Antennas NOTE: For the best results, use 75-ohm coaxial cable to connect an outdoor antenna to the receiver. For better FM reception, you can also use a rabbit-ear TV antenna (for indoor use only) or an outdoor VHF TV antenna. To connect the TV antenna to the receiver, you need a VHF/UHF FM splitter (not included). Radio Shack stores carry a full line of quality outdoor antennas and antenna connection accessories. WARNING: To prevent injury, read and follow all cautions and warnings that accompany the outdoor antenna. For the best radio reception, use an outdoor antenna. Follow these steps to connect an outdoor FM antenna to the receiver using 75 ohm cable. NOTE: If your antenna has 300 ohm twin-lead cable, consult your local Radio Shack store for the correct adapter. 1. Disconnect the supplied FM antenna from the receiver's FM UNBAL 75 ohm terminal. 2. With a stripping tool, remove about 1 1/2 inches of the cable's outer insulation to expose the cable's shielding. 3. Fold back the insulation from the inner insulation. 4. Remove about 1 inch of the inner insulation from around the center wire. CAUTION: The cable's shielding should only touch the GND terminal. 5. Pull the shielding to one side. Connect the center wire to the receiver's FM UNBAL 75 ohm terminal. Twist the shielding to secure any loose wire strands, and connect it to the GND terminal. NOTE: Grounding is not necessary for reception, but we recommend it to avoid damage from lightning when you use an outdoor FM antenna and for better FM reception. Use a separate piece of thick polyvinyl insulated wire to connect the GND terminal to an earth ground such as a metal cold-water pipe. WARNING: Never connect a wire to a gas pipe for grounding since sparks might ignite the gas. USING ONE REMOTE CONTROL FOR MORE THAN ONE UNIT NOTE: When you plug the cable into a component's CONTROL IN jack, that component's remote sensor does not function. If you also have an Optimus professional series CD player, VCR, or cassette deck with the OSR mark, you can connect its CONTROL IN jack to the receiver so you can control all of your equipment with a single remote control. You can also use the other component's remote control by pointing it at the receiver's front panel. 1. Connect each component to the receiver. 2. Connect the cable supplied with the CD player, VCR, or cassette deck between the receiver's CONTROL OUT jack and the other component's CONTROL IN jack. 3. When you want to control more than one other component using the receiver's remote control, daisy-chain the CONTROL OUT and CONTROL IN connections as shown. INSTALLING THE REMOTE CONTROL'S BATTERIES The remote control use two AA batteries (not included). For the longest battery life, we recommend Radio Shack's alkaline batteries (Cat. No. 23-557). 1. Press and open the battery compartment cover. 2. Place two fresh AA batteries in the compartment as indicated by the polarity symbol (+ and -) marked in the compartment. CAUTIONS: Use only fresh batteries of the recommended size and type. Always remove old or weak batteries. Batteries can leak chemicals that can damage electronic circuits. NOTE: If the remote's range is reduced, replace the batteries immediately. 3. Replace the battery compartment cover. USING THE AC POWER OUTLET Your receiver has an AC power outlet that you can use to power an electronic device, such as a turntable, cassette deck, VCR, and so on. This switched outlet turns on and off with the receiver and provides a maximum of 100 Watts. CAUTION: Do not connect appliances with high power consumption, such as a heater, iron, monitor, or TV, to this AC outlet. Doing so can cause a risk of overheating and fire, and could damage the receiver. CONNECTING TO AC POWER Before you plug in the receiver's power cord, double check all other connections. To power the receiver, plug the supplied power cord into a standard AC outlet. The power cord's plug is polarized and fits only one way. WARNING: To prevent electric shock, do not use this polarized plug with an extension cord, receptacle, or other outlet unless you can fully insert the blades to prevent blade exposure. DEMONSTRATION DISPLAY To see a demonstration of the receiver's display, press and hold RETURN while turning on power. The receiver cycles through several demonstration displays. To exit the demonstration mode, press any key. (SP/LB 03/06/96)
