Introducing the Optimus STAV-3790
Your Optimus STAV-3790 Audio/Video Receiver operates as the perfect
control center for your audio/video system. It combines 100 watts-perchannel of clean power with modern styling. It provides connections for
one tape deck, one VCR, two audio/video sources, an additional tape
deck or audio source, a CD player, and a video monitor.
Your receiver also has special sound options. Dolby Digital produces the
digitally-processed true lifelike sound in every channel including subwoofer. Dolby Pro Logic® Surround Sound delivers movie theater sound
for audio/video programs (especially those encoded with Dolby Surround Sound signals). DSP Effects creates a listening environment that
simulates a concert hall, jazz club, theater, or a dance hall.
In addition, you can connect a multi-channel decoder or DVD player
with 5.1-channel output so that all five channels and subwoofer have
independent signals.
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.
Midnight Listening Mode Lets you enjoy the quality surround sound even at low volumes without
disturbing others.
Optical Digital Output Lets you directly output the digital source signals to a digital recording
device, such as MD, DAT, or CD-R.
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 compati-
ble components connected to the receiver.
Note: The remote control requires two AA batteries (not supplied).
We recommend you record the receiv er’s serial number here. The number is on the receiver’s back panel.
Serial Number:_____________________________________________
Note to the Cable TV System Installer:
This reminder is provided to call the CATV system installer’s attention to Article 820-40 of the National Electrical Code that
provides guidelines for proper grounding and, in particular, specifies that the cable ground shall be connected to the grounding system of the building as close to the point of cable entry as practical.

Caution:
Make all the necessary connections before you plug in or turn on the receiver.

Person in Listening Area
Normal Listening Point
• 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 particularly important for the center
speaker since it is usually located
closest to the TV.

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 different locations for your speakers.
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.
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.
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 dispersion. You can angle the speakers toward you for better
stereo effect.
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 26). Also, place the center speaker above,
below, or behind the TV. If you place it beside the TV, the picture may
not coincide with the sound.
You can also compensate the speaker positioning by adjusting the control settings for the front, center, or subwoofer speakers. See “Initial
Setup” on Page 17.

Preparing Your Receiver
Connecting Speakers
Follow these guidelines when you select
and connect speakers.
• Only connect speakers that are rated
at between 6 and 16 Ohms.
• Be sure you properly connect all
speakers.
• Do not connect two pairs of speakers
to a single set of terminals at the
same time.
• Optimus and other high-quality speakers have color-coded speaker terminals (red for positive polarity and black
for negative polarity). Use these colorcoded terminals as a guide to help
you properly connect the speakers to
the receiver.
• Use 16-gauge (or larger) speaker wire
for all speaker connections, and consider possible speaker locations before you decide how much speaker
wire you need.
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 steps to prepare the speaker wires.

1. Cut the speaker wires to the necessary length.
2. Separate the wires about 4 inches on each end.
3. Using a wire stripper, carefully strip about 3/4 inch of insulation
from the end of each conductor.
4. Twist the end of each conductor to secure any loose wire strands.

Note: If you have a turntable with magnetic cartridge and want to connect it to the STAV-3790, you need to connect a pre-amplifier between
the turntable and the receiver. Some turntables have a switchable builtin amplifier: if your turntable has this feature, switch it to preamp
mode. Connect the output of the pre-amplifier to any unused audio
input jacks (
MD/TAPE1, CD, TAPE2 MONITOR, TV/SAT, DVD/LD
, or
VCR
).

In many areas, the supplied indoor AM loop and FM antennas provide
satisfactory reception.
AM Antennas
Assemble the supplied AM 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. 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.
Attach the antenna wires to the
AM LOOP ANTENNA
nals (upper two terminals).
Place the antenna on a flat surface and rotate it for the best AM recep-
tion.
Notes:
• Keep the AM loop antenna connected even when you use another
indoor antenna or an outdoor AM antenna.
• Ensure that the antenna does not touch the receiver or any other
metal object.
• 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 RadioShack
store.

Warning:
To prevent injury, read and follow all cautions and warnings that accompany the outdoor antenna.
Caution:
The cable’s shielding should
only touch the terminal.
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.
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
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 cen-
ter wire.

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 ser-
vice grounding electrode system.
Warning: Never connect a wire to a gas pipe for grounding since sparks
might ignite the gas.
