STA-100 Receiver (310-2089) Connections Faxback Doc. # 16419 BEFORE MAKING CONNECTIONS: Do not plug in the Receiver's power cord. Be sure POWER is off. NOTE: To reduce hum, use shielded audio cables for all connections except speakers. SPEAKERS The STA-100 has two sets of A (main) speaker outputs - use only one set. If your speakers have phono plug inputs, use the Receiver's phono plug outputs and set of unshielded speakers cables. Otherwise use the Receiver's screw terminal outputs. For maximum bass response, be sure to observe proper phasing. Connect the + Receiver speaker output to the speaker terminal labeled A, 1 or +; and the - output to the speaker terminal labeled B, 2 or -. Most speaker wire is marked with a edge along one conductor or has one color-coded conductor. If you use preassembled phono plugs, phasing will automatically be correct. Connect B (remote) speakers following the instructions above. Be sure the speakers are phased properly. NOTES: The STA-100's outputs are designed for 4-16 ohm speakers. However, when more than one set of speakers is being connected, use only 8-16 ohm systems. This will prevent the amplifier from being overloaded. When using the screw terminals, be sure no stray strands of wire touch a second terminal or the chassis - a harmful short could result. Connect no more than two sets of speakers to the Receiver. Use only as much wire as necessary to connect the speakers. If you are using 4-ohm speakers, connect only one set of speakers, or use only one set of speakers at a time. That is, don't use A+B if one set is 4 ohms. Low-impedance speaker systems will tend to trip the automatic circuit protection/amplifier shutdown circuitry when operating at high volume levels (to prevent damage from amplifier overdrive). TURNTABLE Connect the turntable leads to the PHONO inputs. If the turntable has a ground wire (usually green or black), connect it to the PHONO GND screw. Plug the turntable's power cord into an AC outlet or Receiver's UNSWITCHED convenience outlet. NOTE: If the turntable has a ceramic or crystal cartridge, connect it to the AUX jack. TAPE DECK For recording, connect the Receiver's TAPE OUT jacks to the recorder's Aux or Line input. For playback, connect the deck's Line or Output jacks to the Receiver's TAPE IN jack. If you want to duplicate (or dub) a recording, or make two recordings at one time, use shielded cable to connect the STA-100's DUB OUT jacks to a second tape recorder's input. If your tape deck has a DIN-type socket, use a cable with DIN-type connectors and plug into the DIN-type socket on the Receiver. Use either phono jacks or DIN jack, not both. ANTENNAS Be sure the line cord FM antenna is connected to the FM ANT 300 ohm terminal. The built-in AM antenna requires no attention. If you think you need an external antenna, see "Hints and Tips" (Faxback Doc. # 16421). AUXILIARY Plug the output from any high level source into the AUX jacks. This input is ideal for a second tuner, TV audio, ceramic or crystal phono cartridges, a tape player, shortwave radio, etc. (ALL-08/10/95)
