• 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 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

onnecting Speakers

Follow these guidelines when you select
and connect speakers.

• Only connect speakers that are rated
at between 8 and 16 Ohms.

• Be sure you properly connect all
speakers.

• Do not connect t wo pairs of speakers
to a single set of terminals at the
same time.

• Realistic, Optimus, and other high­quality speakers have color-coded
speaker terminals (red for positive po­larity and black for negative polarity).
Use these color-coded 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.

Connecting a Subwoofer Amplifier

Y our 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 re-creating the rumble of an earth­quake, the bone-jarring percussion of a cannon, and more. To use the sub­woofer output, simply connect
line-level input or to an amplifier to which you have connected a subwoofer.

Antenna

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
as shown.

Attach the antenna wires to the
(upper two terminals).

Place the antenna on a flat surface and rotate it for the best AM reception.

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.

You can also use a RadioShack shortwave antenna kit (Cat. No. 278-758),
which makes an excellent outdoor AM antenna. Connect the outdoor AM
antenna wire to the receiver’s AM terminal, as shown.

FM Antennas

Connect the supplied FM antenna to the

For better FM reception, you can also use a rabbit-ear TV antenna (for indoor

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

You can also use the other component’s remote control by pointing it at the
receiver’s front panel.

1. Connect each component to the receiver as shown in “Connecting Pro­gram Sources” on Page 9.

Note:

Cautions:

• 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.

Note:

If the remote’s range is reduced,

replace the batteries.

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 the volume to a comfortable level.

• Do not listen at extremely high volume levels. Extended high­volume 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.

Care and Maintenance

Your Optimus STAV-3770 Audio/Video 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 and its remote control only in normal temperature
environments. Temperature 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
receiver.

Use only fresh batteries of the recommended size and type in the remote con­trol. Always remove old or weak batteries. They can leak chemicals that can
destroy electronic circuits.

Modifying or tampering with your receiver’s internal components can cause a malfunction and m ight invalidate the receiver’s
warranty and void your FCC authorization to operate it. If the receiver is not operating as it should, take it to your local
RadioShack store for assistance.

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.
