Introducing the Optimus STAV-3770
Your Optimus STAV-3770 Audio/Video Receiver is the perfect control center for
your audio/video system. It combines 100 watts-per-channel of clean power
with modern styling. And, it provides connections for one tape deck, one audio/
video source, one more tape deck or audio/video playback source, a turntable,
a CD player, and a video monitor.
Your receiver also has special sound options. Dolby Pro Logic‘ Surround Sound
delivers movie theater sound for audio/video programs (especially those
encoded with Dolby Surround Sound signals). Dolby 3CH Logic provides a
wider sound field than ordinary playback. DSP Effects creates a listening envi-
ronment that simulates a concert hall, jazz club, theater, or a dance hall. Dolby
Virtual provides a three-dimensional sound field using only the front left and
right speakers.
Additional features include:
Digital-Synthesized Tuner Precisely tunes to AM and FM stations.
30 Memory Locations Let you store and recall the frequencies for up to 30 AM/FM stations.
Automatic Tuning Searches for the next available AM/FM station.
Tape Monitoring Lets you listen to the actual recording as you record, if your tape deck has a
tape-monitoring feature.
Built-In Protection Circuits Automatically turn off the receiver to help avoid power surges or short circuit
damage.
Remote Control Lets you use a single remote control for the receiver and other compatible com-
ponents connected to the receiver.
Note: The remote control requires two AA batteries (not supplied).
We recommend you record the receiver’s serial number here. The number is on the re-
ceiver’s back panel.

ABLE PARTS INSIDE. REFER SERVICING
TO QUALIFIED PERSONNEL.
Carts — Move the product on a cart carefully. Quick stops, excessive force, and
uneven surfaces may cause the product/cart to overturn.
Ventilation — Slots and openings in the cabinet provide ventilation, ensure reli-
able operation, and protect from overheating. Do not block or cover these open-
ings, and do not place the product on a bed, sofa, rug, or other similar surface. Do
not place the product in a built-in bookcase or rack unless it provides proper ven-
tilation as specified by the manufacturer.

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.
Midway Point
Between Speakers
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.
Normal ListeningPoint
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 front speakers at the
front of your listening area, and place the (rear) surround speakers behind or to
the sides of the listening point (see “Using Advanced Sound Options” on
Page 21). 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.

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.
• Only connect speakers that are rated
at between 8 and 16 Ohms.
Follow these steps to prepare the speaker wires.
• Be sure you properly connect all
speakers.
Wire Strands
• Do not connect two pairs of speakers
to a single set of terminals at the
same time.
Speaker Wire
• Realistic, Optimus, and other high-
quality speakers have color-coded
speaker terminals (red for positive po-
larity and black for negative polarity).
Use these color-coded terminals as a
guide to help you properly connect the
speakers to the receiver.
Wire Strands
Conductor
• Use 16-gauge (or larger) speaker wire
for all speaker connections, and con-
sider possible speaker locations be-
fore 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.

splitter (not included). RadioShack stores carry a full line of quality antennas
and antenna connection accessories.

Preparing Your Receiver
For the best radio reception, use an outdoor antenna. Follow these steps to
connect an outdoor FM antenna to the receiver using 75Ω coaxial cable.
Warning: To prevent injury, read and fol-
low all cautions and warnings that ac-
company the outdoor antenna.
Note: If your antenna has 300Ω twin-lead cable, consult your local RadioShack
store for the correct adapter.
1. Disconnect the supplied FM antenna from the receiver’s FM UNBAL 75Ω
terminal.
2. With a stripping tool, remove about 11/2 inches of the outdoor antenna
cable’s outer insulation to expose the cable’s shielding.
3. Fold back the shielding from the inner insulation.
4. Remove about 1 inch of the inner insulation from around the center wire.

5. Pull the shielding to one side. Connect the center wire to the receiver’s FM
UNBAL 75Ω terminal. Twist the shielding to secure any loose wire strands,
and connect it to the FM UNBAL 75Ω terminal.
Caution: The cable’s shielding should
only touch the terminal.

Note: Grounding is not necessary for reception, but we recommend it for better
FM reception and to avoid damage from lightning when you use an outdoor FM
antenna. Use a separate piece of thick polyvinyl insulated wire to connect the
terminal to the building’s power service grounding electrode system.
Warning: Never connect a wire to a gas pipe for grounding since sparks might
ignite the gas.

The remote control uses two AA batteries (not included). For the longest battery
life, we recommend alkaline batteries (such as RadioShack Cat. No. 23-557).
Installing the
Remote Control’s Batteries
1. Press and slide open the battery compartment cover.
Cautions:
2. Place two fresh AA batteries in the compartment as indicated by the
polarity symbols (+ and –) marked in the compartment.
• Use only fresh batteries of the required
size and recommended type.
• Always remove old or weak batteries.
Batteries can leak chemicals that can
damage electronic circuits.
3. Replace the battery compartment cover.
Note: If the remote’s range is reduced,
replace the batteries.
