Optimus STA-7500 - Connecting Audio Sources; Connecting the Remote Cable

When connecting a speaker wire, use the wire’s
color-coding or marking to help you correctly con-
nect it to the receiver’s positive or negative termi-
nals. For example, be sure the conductor that is
connected to the speaker’s negative (—) terminal is
connected to the receiver’s negative (—) terminal.
This greatly affects the bass.
Note: Some speakers’ connection terminals are
marked + and —. Others have a mark or dot next
to the positive terminal and no mark for the nega-
tive terminal.
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
e 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 re-
ceiver’s corresponding R input jack.
Connecting a Turntable
Use a turntable with a magnetic cartridge. For bet-
ter sound and less wear on your records, we recom-
mend 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 mag-
netic 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-5500 (Cat. No. 14-667)
or SCT-7500 (Cat. No. 14-668) offers the added con-
venience of remote operation using the receiver’s
remote controls.
Connect the tape deck’s output jacks to the re-
ceiver’s TAPE IN jacks. Connect the receiver’s TAPE
OUT jacks to the tape 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 distor-
tion, and provide a dynamic range close to that of
alive 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. No. 42-5036) or
CD-7500 (Cat. No. 42-5038) offers the added con-
venience 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 re-
ceiver, 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.
