Preparing Your Receiver
Caution: Make all the necessary connections before you plug in or turn on the receiver.
Where you place your speakers (not supplied) can make a noticeable difference
in your system’s sound. The guidelines in this section will help you choose the
best locations. After you use your receiver for a while, you might want to try dif-
ferent locations for your speakers.
Positioning Speakers
a
L
R
Bass response depends largely on speaker location. For strong bass, place the
speakers in the corners of the room. If you want even stronger bass, place the
speakers directly on the floor. If the bass is too strong, move the speakers
slightly away from the corners of the room, or raise them 6 to 18 inches off the
floor. You can buy speaker stands at your local RadioShack store.
Halfway Point
Between Speake
b
a=b
The distance between the speakers should be about the same as the distance
between the normal listening point and the point halfway between the speakers.
If you place the speakers too close together, you reduce the stereo separation.
If you place them too far apart, you reduce the bass effect and create a hole in
the middle of the sound.
Person in Listening Area
Most speakers have a tweeter dispersion angle of about 60 degrees. Ideally,
your listening position should be just inside the overlap area of the tweeter dis-
persion. You can angle the speakers toward you for better stereo effect.
• Surround speakers generally sound
best if you position them above ear
level.
• To avoid interference with the picture
on a nearby TV, use magnetically
shielded speaker systems. This is par-
ticularly important for the center
speaker since it is usually located
closest to the TV.
To position your speakers for surround sound, place the A or B speakers at the
front of your listening area, and place the surround speakers behind or to the
sides of the listening point (see “Using Advanced Sound Options” on Page 20).
Also, place the center speaker above, below, or behind the TV. Sound might not
appear to coincide with the picture if you place it beside the TV.

Preparing Your Receiver
Connecting Speakers
Preparing the Speaker Wires
Speaker wire consists of two conductors (individual wires) encased in insulation
and is usually color-coded or marked with a ridge along one side so you can
identify each conductor. Use these markings as a guide to help you properly
connect the speakers to your receiver.
Follow these guidelines when you select
and connect speakers.
• Be sure you properly connect all
speakers.
Follow these steps to prepare the speaker wires.
• Do not connect two pairs of speakers
to a single set of terminals (A or B) at
the same time. When you use two
pairs of speakers, connect one set to

and one set to
• Optimus and other high-quality speak-
ers have color-coded speaker termi-
nals (red for positive polarity and
black for negative polarity). Use these
color-coded terminals as a guide to
help you properly connect the speak-
ers to the receiver.

• Use 16-gauge (or larger) speaker wire
for all speaker connections, and con-
sider possible speaker locations
before you decide how much speaker
wire you need.
1. Cut the speaker wires to the necessary length.
2. Separate the wires about 4 inches on each end.
3
3. Using a wire stripper, carefully strip about /4 inch of insulation from the
end of each conductor.
4. Twist the end of each conductor to secure any loose wire strands.

Preparing Your Receiver
Connecting the A and B Speakers
Note: Be sure you connect the
receiver’s right and left positive (+) and
negative (–) terminals to the speaker’s
corresponding right and left positive (+)
and negative (–) terminals.
Follow these steps to connect the right speaker to the receiver’s right FRONT
SPEAKERS A terminals.
1. Press the receiver’s FRONT SPEAKERS A R (+) red lever and insert the
ridged or color-coded conductor’s end into the small hole. Pull back the
lever to secure the conductor.
+

–
2. Press the receiver’s FRONT SPEAKERS A R (–) black lever and insert the
other conductor’s end into the small hole. Pull back the lever to secure the
conductor.
3. Connect the ridged or color-coded conductor’s loose end to the right
speaker’s positive (+) terminal.
4. Connect the remaining loose conductor to the right speaker’s negative (–)
terminal.
Repeat Steps 1 through 4 to connect the left speaker to the receiver’s left
FRONT SPEAKERS A terminals.
Repeat this entire process to connect a second pair of speakers to the FRONT
SPEAKERS B terminals.
Connecting Surround-Sound Speakers
You can connect a pair of speakers to the receiver’s REAR SPEAKERS terminals
for surround-sound programs. Follow the steps in “Connecting the A and B
Speakers.”
Connecting the Center Speaker
The center speaker gives additional ambience to surround sound. Connect the
center speaker to the CENTER SPEAKER terminals. Follow the steps in “Con-
necting the A and B Speakers.”
Connecting Center Channel and Subwoofer Amplifiers
To increase the center channel’s output power, you can connect an amplifier to
the CENTER jack. Then connect the center channel speaker to the amplifier.
Your receiver includes a line-level subwoofer output. Connecting a subwoofer to
your system dramatically extends bass response for incredible richness and
depth. When you listen to surround-sound programs, a subwoofer enhances
your home theater experience by realistically recreating the rumble of an earth-
quake, the bone-jarring percussion of a cannon, and more.
To use this output, simply connect it to an amplified subwoofer’s line-level input
or to an amplifier to which you have connected a subwoofer.
RadioShack stores sell a variety of suitable subwoofers and amplifiers.

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.

Preparing Your Receiver
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 out-
let turns on and off with the receiver and provides a maximum of 100 Watts.
Using the AC Power Outlet
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 over-
heating and fire, and could damage the
receiver.

Listening Safely
To protect your hearing, note the following when using headphones.
• Set the volume to its lowest setting before you begin listening. After you
begin listening, adjust volume to a comfortable level.
• Do not listen at extremely high volume levels. Extended high-
volume listening can lead to permanent hearing loss.
• Once you set the volume, do not increase it. Over time, your ears adapt to
the volume level, so a volume level that does not cause discomfort might
still damage your hearing.

decks.
You can copy, or dub, a cassette tape from one cassette deck to another.
You can use either deck as the playback or recording deck. However, if you

Using Advanced Sound Options
Your receiver has four special sound options: Dolby Pro-Logic Surround, Dolby
3CH Logic, Studio-Effect Surround, and Simulated Surround. These special
options enhance a program source.
Notes:
• To get the full benefit from programs encoded with Dolby Surround
Sound, you need a stereo VCR.
• Dolby Surround does not operate correctly if the signal passes through a
graphic equalizer. If you connected an equalizer to the TAPE 2 MONITOR
jacks, do not select TAPE 2 MONITOR when you listen to Dolby Surround
signals.
To activate Dolby Pro-Logic Surround or Dolby 3CH Logic, press its button. For
studio effect, simulated surround, or arena effect, press SFC MODE until the
desired option appears on the display. On the remote control, press 3CH LOGIC
to select Dolby 3CH Logic Sound and use SURR MODE for other sound options.
Dolby Pro-Logic Surround
Dolby Pro-Logic Surround puts you in the middle of the action. The center- and
rear-channel speakers add incredible realism by directing the sound to the
appropriate speakers, making you feel like you are really there. You can find
hundreds of movies, television shows, and compact discs produced with Dolby
Surround.
Dolby 3CH Logic
Dolby 3CH Logic produces a more spacious sound field than is possible with
ordinary stereo playback by combining the front and rear speaker sounds.
Select this mode when you play a Dolby Surround Sound program and do not
have rear speakers. The rear channel’s sound is sent to the front left and right
speakers.
Studio Effect
Studio Effect gives the effect of listening in a recording studio. The front speak-
ers provide normal stereo, and the rear speakers provide a subtly reverberated
sound. Select this mode when you listen to sources not encoded with Dolby
Surround.
Simulated Surround
Simulated Surround simulates a surround effect when you listen to a monaural
(mono) source.

Using the Remote Control
The remote control works up to a distance of about 23 feet, and within a 30-
degree angle on either side of the receiver. Point the control at the receiver’s
front panel and press the desired button(s).
Many buttons on the remote control work the same as buttons on the receiver’s
front panel. Use these buttons exactly as you would use the corresponding but-
tons on the receiver.

The remote control can also control other compatible audio/video components
when you connect them to the receiver’s CONTROL OUT jack. Set the switch to
AUDIO to control audio components such as CD players or cassette decks. Set
the switch to VCR to control video components such as a VCR.
When you set the switch to VCR, dual-function buttons control the function
marked in gold next to the button. For example, the button marked CENTER
MODE and TEST TONE operates as the center mode adjust when you set the
switch to AUDIO and as the test tone function when you set the switch to VCR.

Care and Maintenance
Your STAV-3580 Digital Synthesized A/V Surround Receiver is an example of superior design and craftsmanship. The following
suggestions will help you care for the receiver so you can enjoy it for years.
Keep the receiver dry. If it gets wet, wipe it dry immediately. Liquids can contain
minerals that can corrode the electronic circuits.
Handle the receiver gently and carefully. Dropping it can damage its circuit
boards and can cause the receiver to work improperly.
Use and store the receiver only in normal temperature environments. Tempera-
ture extremes can shorten the life of electronic devices, damage batteries, and
distort or melt plastic parts.
Keep the receiver away from dust and dirt, which can cause premature wear of
parts.
Wipe the receiver with a damp cloth occasionally to keep it looking new. Do not
use harsh chemicals, cleaning solvents, or strong detergents to clean the
CLEANER
receiver.
Use only fresh batteries of the recommended size and type in the remote con-

The FCC Wants You to Know
Your receiver might cause radio or TV interference even when it is operating
properly. To determine whether your receiver is causing the interference, turn off
your receiver. If the interference goes away, your receiver is causing it. Try to
eliminate the interference by:
• Moving your radio or TV away from the receiver
• Connecting your receiver to an outlet that is on a different electrical circuit
from the radio or TV
• Contacting your local RadioShack store for help
If you cannot eliminate the interference, the FCC requires that you stop using
your receiver.
